<?php
echo "openssl version text: " . OPENSSL_VERSION_TEXT . "\n";
echo "openssl version number: " . OPENSSL_VERSION_NUMBER . "\n";
?>
will output something like:
openssl version text: OpenSSL 1.0.2d 9 Jul 2015
openssl version number: 268443727

OPENSSL_VERSION_NUMBER(integer)
注意:
这些常量是在5.2.0版本中添加的。

Plase note that these constants show not
the current system openssl library version
but version PHP was compiled with.
