sqlite_fetch_array

SQLiteResult::fetch

SQLiteUnbuffered::fetch

(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)

sqlite_fetch_array -- SQLiteResult::fetch -- SQLiteUnbuffered::fetch — Fetches the next row from a result set as an array

说明

sqlite_fetch_array ( resource $result [, int $result_type = SQLITE_BOTH [, bool $decode_binary = TRUE ]] ) : array

面向对象风格 (method):

SQLiteResult::fetch ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = TRUE ]] ) : array

SQLiteUnbuffered::fetch ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = TRUE ]] ) : array

Fetches the next row from the given result handle. If there are no more rows, returns FALSE, otherwise returns an associative array representing the row data.

参数

result: The SQLite result resource. This parameter is not required when using the object-oriented method.
result_type: 可选的 result_type 参数接受常量，且决定返回的数组如何被索引。使用 SQLITE_ASSOC 会仅返回关联索引（已命名字段），而 SQLITE_NUM 会仅返回数值索引。SQLITE_BOTH 会同时返回关联和数值索引。SQLITE_BOTH 是此函数的默认值。
decode_binary: 当 decode_binary 参数设置为 TRUE（默认值）时，PHP 会解码那些由 sqlite_escape_string() 编码后的二进制数据。通常应保留此值为其默认值，除非要与其他使用 SQLlite 的应用程序建立的数据交互。

返回值

Returns an array of the next row from a result set; FALSE if the next position is beyond the final row.

由 SQLITE_ASSOC 与 SQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。

范例

Example #1 Procedural example


<?php
$dbhandle = sqlite_open('sqlitedb');
$query = sqlite_query($dbhandle, 'SELECT name, email FROM users LIMIT 25');
while ($entry = sqlite_fetch_array($query, SQLITE_ASSOC)) {
    echo 'Name: ' . $entry['name'] . '  E-mail: ' . $entry['email'];
}
?>

Example #2 Object-oriented example


<?php
$dbhandle = new SQLiteDatabase('sqlitedb');

$query = $dbhandle->query('SELECT name, email FROM users LIMIT 25'); // buffered result set
$query = $dbhandle->unbufferedQuery('SELECT name, email FROM users LIMIT 25'); // unbuffered result set

while ($entry = $query->fetch(SQLITE_ASSOC)) {
    echo 'Name: ' . $entry['name'] . '  E-mail: ' . $entry['email'];
}
?>

[Editor's note: to get short column names there's an undocumented PRAGMA setting. You can exec "PRAGMA short_column_names = ON" to force that behavior.]



I noticed that if you use Joins in SQL queries, the field name is messed up with the dot!

for example if you have this query:

SELECT n.*, m.nickname FROM news AS n, members AS m WHERE n.memberID = m.id;



now if you want to print_r the results returned using SQLITE_ASSOC type, the result array is like this :

array

(

  [n.memberID] => 2

  [n.title] => test title

  [m.nickname] => NeverMind

  [tablename.fieldname] => value

)



and I think it looks horriable to use the variable ,for example, $news['m.nickname'] I just don't like it!



so I've made a small function that will remove the table name (or its Alias) and will return the array after its index is cleaned

<?php

function CleanName($array)

{

  foreach ($array as $key => $value) {

    //if you want to keep the old element with its key remove the following line

      unset($array[$key]);



   //now we clean the key from the dot and tablename (alise) and set the new element

      $key = substr($key, strpos($key, '.')+1);

      $array[$key] = $value;

  }

  return $array;

}

?>
