[RESOLVED] substr to get file extension

[DKY]

I have the file and extension stored in a database and would like to know if there's something out there like substr but only backwards or even strchr but backwards? I want to get the extension of a file and right now i'm doing this

If (strchr ( $Row["File"], "." ) == ".pdf")

but if someone uploads a file with .'s in it then it doesn't work.

There's "strrchr()" (linked to from the manual's descriptive list of string functions), and there's also "pathinfo()".

$ext = end(explode('.', $file));
works beautifully, thanks

Uh, sure.
