Get the file extension [duplicate]

Question

I'm exploding on "." to get file format and name:

list($txt, $ext) = explode(".", $name);

The problem is that some files have names with dots.

How do I explote on the LAST "." so that I get $name=pic.n2 and $ext=jpg from: pic.n2.jpg?

Answer 1

Use pathinfo:

$pi = pathinfo($name);
$txt = $pi['filename'];
$ext = $pi['extension'];
