I use this to find extentions like “file.txt” would show “.txt”, but cant find out how to get the “file” by itself.

function GetFileExtention($filename) {  
$ext = strstr($filename,".");  
return $ext;  
}

I’ve been searching for the last half any hour how to find out of “file.txt” the string “file”.

//edit, Basically I need everything before the “.”.

Thanks.
