PHP Version check

I ran into a problem when I was using your plugin with PHP 5.2.*.
You use the function strstr() in line 107 with 3 parameters, which is not supported before PHP Version 5.3.0.

In line 107 you should use instead:
$url = $uri;
if($qry) {
if (version_compare(PHP_VERSION, ‘5.3.0’) >= 0)
$url=strstr($uri,’?’,true);
else
$url=substr($uri,0,$qry);
}

(Or just always substr())
