PHP conditional for vBulletin version?

[kh99]

There's a PHP function version_compare() for doing compares on version strings: http://us2.php.net/manual/en/functio...on-compare.php and the vbulletin version is in $vbulletin->versionnumber, so you could do something like

PHP Code:

if (version_compare(@$vbulletin->versionnumber, '4.1.4', '>=')) 
{
...
} 


An example I found in the vb code had the '@' there, I'm not sure why, I guess it would suppress an error message if $vbulletin->versionnumber didn't exist but I don't know if or when that would happen.
