Determine PHP version.

[xconspirisist]

I've tried $SERVER['SERVER_SOFTWARE'] and $SERVER['SERVER_SIGNATURE'], although both seem very unreliable, as different servers broadcast them, and some don't. Is there a more reliable method?

edit: Whoops: phpversion() 🙂

hi
you use phpversion()
http://php.net/phpversion

<?php

// prints e.g. 'Current PHP version: 4.1.1'
echo 'Current PHP version: ' . phpversion();

echo '<br>';

// or
$version =  phpversion();
echo 'PHP ' . $version;

echo '<br>';

if ( $version >= "4.3.3" )
    echo 'version is PHP 4.3.3 or later';
else
    echo 'before PHP 4.3.3';
