After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. ' into '), so I created my own by improving on the existing ones:
function phpinfo2array() {
$entitiesToUtf8 = function($input) {
// http://php.net/manual/en/function.html-entity-decode.php#104617
return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
};
$plainText = function($input) use ($entitiesToUtf8) {
return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
};
$titlePlainText = function($input) use ($plainText) {
return '# '.$plainText($input);
};
ob_start();
phpinfo(-1);
$phpinfo = array('phpinfo' => array());
// Strip everything after the <h1>Configuration</h1> tag (other h1's)
if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
return array();
}
$input = $matches[1];
$matches = array();
if(preg_match_all(
'#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
'(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
$input,
$matches,
PREG_SET_ORDER
)) {
foreach ($matches as $match) {
$fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
if (strlen($match[1])) {
$phpinfo[$match[1]] = array();
} elseif (isset($match[3])) {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
} else {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $fn($match[2]);
}
}
}
return $phpinfo;
}
The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):

phpinfo
(PHP 4, PHP 5, PHP 7, PHP 8)
phpinfo — 输出关于 PHP 配置的信息
说明
phpinfo(int
$what = INFO_ALL): bool输出 PHP 当前状态的大量信息，包含了 PHP 编译选项、启用的扩展、PHP 版本、服务器信息和环境变量（如果编译为一个模块的话）、PHP环境变量、操作系统版本信息、path 变量、配置选项的本地值和主值、HTTP 头和PHP授权信息(License)。
因为每个系统安装得有所不同，phpinfo() 常用于在系统上检查 配置设置和 预定义变量。
phpinfo() 同时是个很有价值的、包含所有 EGPCS(Environment, GET, POST, Cookie, Server) 数据的调试工具。
参数
-
what -
可以用以下的一个或多个 constants 用位运算传递给可选的
what参数来定制输出的信息。 该参数可以把常量相加或者用按位或操作符按位运算。phpinfo() 选项 Name (constant) Value Description INFO_GENERAL 1 配置的命令行、 php.ini 的文件位置、建立的时间、Web 服务器、系统及更多其他信息。 INFO_CREDITS 2 PHP 贡献者名单。参加 phpcredits()。 INFO_CONFIGURATION 4 当前PHP指令的本地值和主值。参见 ini_get()。 INFO_MODULES 8 已加载的模块和模块相应的设置。参见 get_loaded_extensions()。 INFO_ENVIRONMENT 16 环境变量信息也可以用 $_ENV 获取。 INFO_VARIABLES 32 显示所有来自 EGPCS (Environment, GET, POST, Cookie, Server) 的 预定义变量。 INFO_LICENSE 64 PHP许可证信息。参见 » license FAQ。 INFO_ALL -1 显示以上所有信息。
返回值
成功时返回 true， 或者在失败时返回 false。
更新日志
| 5.5.0 | Logo GUIDs were replaced with data URIs, and so turning off expose_php now has no effect on the result of phpinfo(). Credits are also now embedded within the output itself instead of linked. |
|---|---|
| 版本 | 说明 |
| 5.2.2 | 增加了“已加载的配置文件”信息，之前只存在“配置文件路径(php.ini)"。 |
范例
示例 #1 phpinfo() 范例
<?php
// 显示所有信息，默认显示 INFO_ALL
phpinfo();
// Show just the module information. 仅仅显示PHP模块信息，
// phpinfo(8) 返回同样的结果。
phpinfo(INFO_MODULES);
?>
注释
注意:
在 PHP 5.5 之前版本，当 expose_php 设置为
off可以禁用一部分信息。 这包括了 PHP 和 Zend 的 logo，以及贡献者名单。
注意:
在命令行（CLI）模式下 phpinfo() 仅会输出纯文本，而不是HTML。
参见
- phpversion() - 获取当前的PHP版本
- phpcredits() - 打印 PHP 贡献者名单
- php_logo_guid()
- ini_get() - 获取一个配置选项的值
- ini_set() - 为一个配置选项设置值
- get_loaded_extensions() - 返回所有编译并加载模块名的 array

Hi.
Here my version of saving php_info into an array:
<?php
function phpinfo_array()
{
ob_start();
phpinfo();
$info_arr = array();
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
$cat = "General";
foreach($info_lines as $line)
{
// new cat?
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
if(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = $val[2];
}
elseif(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
}
}
return $info_arr;
}
// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";
?>

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:
<?php
// start output buffering
ob_start();
// send phpinfo content
phpinfo();
// get phpinfo content
$html = ob_get_contents();
// flush the output buffer
ob_end_clean();
// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], '<i>no value</i>', $html);
if (isset($_SERVER['AUTH_PASSWORD'])) $html = str_replace($_SERVER['AUTH_PASSWORD'], '<i>no value</i>', $html);
echo $html;

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).
<?php
ob_start ();
ob_start (); // Capturing
phpinfo (); // phpinfo ()
$info = trim (ob_get_clean ()); // output
// Replace white space in ID and NAME attributes... if exists
$info = preg_replace ('/(id|name)(=["\'][^ "\']+) ([^ "\']*["\'])/i', '$1$2_$3', $info);
$imp = new DOMImplementation ();
$dtd = $imp->createDocumentType (
'html',
'-//W3C//DTD XHTML 1.0 Transitional//EN',
'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'
);
$doc = $imp->createDocument (
'http://www.w3.org/1999/xhtml',
'html',
$dtd
);
$doc->encoding = 'utf-8';
$info_doc = new DOMDocument ('1.0', 'utf-8');
/* Parse phpinfo's output
* operator @ used to avoid messages about undefined entities
* or use loadHTML instead
*/
@$info_doc->loadXML ($info);
$doc->documentElement->appendChild ( // Adding HEAD element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('head')->item (0),
true // With all the subtree
)
);
$doc->documentElement->appendChild ( // Adding BODY element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('body')->item (0),
true // With all the subtree
)
);
// Now you get a clean output and you are able to validate...
/*
echo ($doc->saveXML ());
// OR
echo ($doc->saveHTML ());
*/
// By that way it's easy to add some style declaration :
$style = $doc->getElementsByTagName ('style')->item (0);
$style->appendChild (
$doc->createTextNode (
'/* SOME NEW CSS RULES TO ADD TO THE FUNCTION OUTPUT */'
)
);
// to add some more informations to display :
$body = $doc->getElementsByTagName ('body')->item (0);
$element = $doc->createElement ('p');
$element->appendChild (
$doc->createTextNode (
'SOME NEW CONTENT TO DISPLAY'
)
);
$body->appendChild ($element);
// to add a new header :
$head = $doc->getElementsByTagName ('head')->item (0);
$meta = $doc->createElement ('meta');
$meta->setAttribute ('name', 'author');
$meta->setAttribute ('content', 'arimbourg at ariworld dot eu');
$head->appendChild ($meta);
// As you wish, take the rest of the output and add it for debugging
$out = ob_get_clean ();
$pre = $doc->createElement ('div'); // or pre
$pre->setAttribute ('style', 'white-space: pre;'); // for a div element, useless with pre
$pre->appendChild ($doc->createTextNode ($out));
$body->appendChild ($pre);
$doc->formatOutput = true; // For a nice indentation
$doc->saveXML ();
?>
All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:
<?php
/* parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();
$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
} elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
}
}
}
}
return $vModules;
}

<?php
// NOTE: When accessing a element from the above phpinfo_array(), you can do:
$array = phpinfo_array();
// This will work
echo $array["General"]["System "];
// This should work also, but it doesn't because there is a space after System in the array.
echo $array["General"]["System"];
// I hope the coder will fix it, so as to save someone else from wasting time. Otherwise, nice script.

This function parses the phpinfo output to get details about a PHP module.
<?php
/** parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();
$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
} elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
}
}
}
}
return $vModules;

check out this cool and fantastic colourful phpinfo()!
<?php

$hexvalue = '0123456789abcdef';
$j = 0;
foreach ($matches as $match)
{
$r = '#';
$searches[$j] = $match;
for ($i = 0; $i < 6; $i++)
$r .= substr($hexvalue, mt_rand(0, 15), 1);
$replacements[$j++] = $r;
unset($r);
}
for ($i = 0; $i < count($searches); $i++)

To extract all of the data from phpinfo into a nested array:
<?php
ob_start();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
foreach($matches as $match)
if(strlen($match[1]))
$phpinfo[$match[1]] = array();
elseif(isset($match[3]))
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
else
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>
Some examples of using individual values from the array:
<?php
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
echo "Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
echo "License: {$phpinfo['PHP License'][0]}<br />\n";
?>
To display everything:
<?php
foreach($phpinfo as $name => $section) {
echo "<h3>$name</h3>\n<table>\n";
foreach($section as $key => $val) {
if(is_array($val))
echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
elseif(is_string($key))
echo "<tr><td>$key</td><td>$val</td></tr>\n";
else
echo "<tr><td>$val</td></tr>\n";
}
echo "</table>\n";
}
?>
Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!
some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)
we need to change two lines:
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>
and
<?php
preg_split( '/\n/', $matches[1] )
?>
to
<?php
preg_split( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>
That's all! Now we have a really flexible addition to phpinfo();

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.
I have changed the preg_match_all() here so that the last <td></td> is optional
<?php
function parsePHPConfig() {
ob_start();
phpinfo(-1);
$s = ob_get_contents();
ob_end_clean();
$a = $mtc = array();
if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
foreach($mtc as $v){
if($v[2] == '<i>no value</i>') continue;
$a[$v[1]] = $v[2];
}
}
return $a;
}
?>

One note on the very useful example by "jon at sitewizard dot ca".
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
These two lines will produce the error "Strict Standards: Only variables should be passed by reference in...". The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:
Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];
This fixes the error.
To wrap it all in an example:
<?php
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER)){
foreach($matches as $match){
if(strlen($match[1])){
$phpinfo[$match[1]] = array();
}elseif(isset($match[3])){
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
}else{
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $match[2];
}
}
}
if(! empty($phpinfo)){
foreach($phpinfo as $name => $section) {
echo "<h3>$name</h3>\n<table class='wp-list-table widefat fixed pages'>\n";
foreach($section as $key => $val){
if(is_array($val)){
echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
}elseif(is_string($key)){
echo "<tr><td>$key</td><td>$val</td></tr>\n";
}else{
echo "<tr><td>$val</td></tr>\n";
}
}
}
echo "</table>\n";
}else{
echo "<h3>Sorry, the phpinfo() function is not accessable. Perhaps, it is disabled<a href='http://php.net/manual/en/function.phpinfo.php'>See the documentation.</a></h3>";
}
}
?>
Frankly, I went thought the trouble of adding this note because the example by "jon at sitewizard dot ca" is probably the best on the web, and thought it unfortunate that it throws errors. Hope this is useful to someone.
Mardy dot Hutchinson at gmail dot com ¶

Embedding phpinfo within your page, that already has style information:
The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.
Yes, we cheat on preparing the selector list.
<?php
ob_start();
phpinfo();
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
# $matches [1]; # Style information
# $matches [2]; # Body information
echo "<div class='phpinfodisplay'><style type='text/css'>\n",
join( "\n",
array_map(
create_function(
'$i',
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
),
preg_split( '/\n/', $matches[1] )
)
),
"</style>\n",
$matches[2],
"\n</div>\n";
?>
Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

I wanted a simple *function* to convert the output of phpinfo into an array. Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c
Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.
== Sample Output ==
[PHP Configuration] => Array

[PHP Version] => 5.2.6
[PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42

I needed a way to quickly scroll through the phpinfo which is a large list of information. so here it is. In the top there is a list with sections, the new section loaded extensions will hold the links to the anchors of the loaded modules. the section session variables will show the current loaded sessions. It's using Domdocument for manipulation so you should have that loaded:
<?php
ob_start();
$exts = get_loaded_extensions();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
//print $phpinfo;
$html_str = $phpinfo;
$html = new DOMDocument();
$html->loadHTML($html_str);
$title = $html->getElementsByTagName("title")->item(0);
$title->nodeValue = "PHP Version ".phpversion();
$body = $html->getElementsByTagName("body")->item(0);
$body->setAttribute("style", "background-color:beige;");
$table = $body = $html->getElementsByTagName("table")->item(3)->nextSibling;
$head = $html->getElementsByTagName("table")->item(0)->nextSibling;
ob_start();
?>
<h2><a name="session_variables">Session variables</a></h2>
<table border="0" cellpadding="2" width="600">
<tr class="h"><th>Variables</th><th>Value</th></tr>
<?php foreach($_SESSION as $key=>$value){
if(is_bool($value)){
$value = ($value)?"true":"false";
}else if(is_array($value)){
$value = '<pre>'.print_r($value, true).'</pre>';
}else if(empty($value) && $value != "0"){
$value = "<i>no value</i>";
}
?>
<tr>
<td class="e"><?=$key?></td>
<td class="v"><?=$value?></td>
</tr>
<?php
}
?>
</table>
<h2><a name="loaded_extensions">loaded extensions</a></h2>
<table border="0" cellpadding="2" width="600">
<tr class="h"><th>Extension</th><th>Version</th></tr>
<?php
natcasesort($exts);
foreach($exts as $value){
$version = phpversion($value);
?>
<tr>
<td class="e" style="width:150px;"><a href="#module_<?=$value?>" style="color:black; background-color:#ccccff;"><?=$value?></a></td>
<td class="v"><?=(!empty($version))?$version:"<i>Unknown</i>" ?></td>
</tr>
<?php
}
?>
</table><br />
<?php
$txt_str = ob_get_contents();
ob_end_clean();
$txt = new DOMDocument();
$txt->loadHTML($txt_str);
$txt_body = $txt->getElementsByTagName("body")->item(0);
foreach($txt_body->childNodes as $child){
$child = $html->importNode($child, true);
$table->parentNode->insertBefore($child, $table);
}
$h2 = $html->getElementsByTagName("h2");
foreach($h2 as $item){
if($item->getElementsByTagName("a")->length == 0){
$value = $item->nodeValue;
$item->nodeValue = "";
$a = $html->createElement("a");
$a->setAttribute("name", strtolower(str_replace(" ", "_", $value)));
$a->nodeValue = $value;
$item->appendChild($a);
}
$a = $item->getElementsByTagName("a")->item(0);
if(!in_array($a->nodeValue, $exts)){
$menu[strtolower(str_replace(" ", "_", $a->nodeValue))] = $a->nodeValue;
}
$top_a = $html->createElement("a");
if(!in_array($a->nodeValue, $exts)){
$txt = $html->createTextNode("(Go to top)");
$top_a->appendChild($txt);
$top_a->setAttribute("href", "#");
}else{
$txt = $html->createTextNode("(Go to extensionlist)");
$top_a->appendChild($txt);
$top_a->setAttribute("href", "#loaded_extensions");
}
$top_a->setAttribute("style", "background-color:beige; font-size:12px; margin-left:5px; margin-top:-5px; color:black;");
$item->appendChild($top_a);
}
ob_start();
?>
<br />
<table border="0" cellpadding="2" width="600">
<tr class="h"><th colspan="2">Sections</th></tr>
<tr>
<?php
$i = 0;
foreach($menu as $key=>$item){
print "<td class='v'><a href='#$key' style='background-color:#cccccc; color:black;'>$item</a></td>";
if($i%2){
print '</tr><tr>';
}
$i++;
}
if($i%2){
print '<td class="v"></td>';
}
?>
</tr>
</table>
<?php
$txt_str = ob_get_clean();
$txt = new DOMDocument();
$txt->loadHTML($txt_str);
$txt_body = $txt->getElementsByTagName("body")->item(0);
foreach($txt_body->childNodes as $child){
$child = $html->importNode($child, true);
$table->parentNode->insertBefore($child, $head);

print $html->saveHTML();

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:
-1, coded in 7 digits:
111 1111
look at this:
1+2+4+8+16+32+64=127
unsigned,127 is:
111 1111
so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1
so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2
so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>
hope this will be useful, that's my 1rst post ^^

Building on SimonD's elegant example to hide the logged-in username and password, which otherwise appear in plain text, the following should work for PHP 5.4+:
<?php
// start output buffering
ob_start();
// send phpinfo content
phpinfo();
// get phpinfo content
$html = ob_get_contents();
// flush the output buffer
ob_end_clean();
// remove auth data
if ( isset( $_SERVER[ 'PHP_AUTH_USER' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_USER' ], '[ protected ]' , $html);
if ( isset( $_SERVER[ 'PHP_AUTH_PW' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_PW' ], '[ protected ]' , $html);
echo $html;
?>
To remove additional items, just add them as above.

If you are embeding the output of the function within a page, the <html> tag can collide and page will distort.
Rather, it is important to extract the contents within the <body> and </body> tags only. Here is how.
<?php
public function info()
{
ob_start();
phpinfo();
$info = ob_get_clean();
$info = preg_replace("/^.*?\<body\>/is", "", $info);
$info = preg_replace("/<\/body\>.*?$/is", "", $info);
echo $info;
}
?>
