Hello,
I'm trying to replace a couple of lines of code:
$dotpos = 1 - (strlen($userfile_name) - strpos($userfile_name, '.'));
$extension = substr($userfile_name, $dotpos);
with a simpler regular expression:
$extension = eregi_replace( "/.*", "", $userfile_name);
However it isn't working..
What I'd like to do is to find the extension of a file name and place that in a
variable. So in
'/home/mike/test.txt', I want to have the statement return 'txt'
Any help would be appreciated..
Mike
