Note:

These constants were added in 5.2.0.

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

Fixed version (patch hexdec conversion + version_compare usage)

<?php

<?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
