How do I rewrite split() to preg_split()

Question

Here is my code that I want to update from 5.1 to 5.3 in php

$filename=$_FILES['file']['name'];

function findexts ($filename) 
{ 
$filename = strtolower($filename) ; 
$exts = split("[/\\.]", $filename) ; 
$n = count($exts)-1; 
$exts = $exts[$n]; 
return $exts;

But I am very confused on how to do it

What error do you get? Tried just replacing `split` with `preg_split`? — Johan Lindskogen, Dec 09 '13 at 03:10
Change `$exts = split("[/\\.]", $filename);` to `$exts = preg_split("[/\\.]", $filename);` — Johan Lindskogen, Dec 09 '13 at 03:11
Hmmm, thank you, it's working now, before I had that code exactly and it said that my resources were invalid, but thank you :) — Cup of Java, Dec 09 '13 at 03:12

Just changing

$exts = split("[/\\.]", $filename);

to:

$exts = preg_split("[/\\.]", $filename);

Should work!

It should be $exts = preg_split("[\\.]", $filename);, as it is in your answer it doesn't recognize your regex. – dendini Mar 20 '14 at 13:01
