    <?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

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