picking off file extentions in php

antken · 08-07-2002, 08:04 AM

hi,

i have an intranet system written in php it is designed to read folders and display their contents and put a nice little icon at the side of the file for example a m$ word document would get a blue letter W at the side.

unfortunatly the way its written it only picks off a 3 letter extention so .html files dont display
is there a way to read the file name from the right upto the . (dot) and put it into a string?

so if i gave it a file name of blah.foobar it would pick off the extention of foobar

thanks
antken

How about:

$string="filename.test.php";
$tok=strtok($string,".");
while ($tok)
{
$filetype=$tok;
$tok=strtok(".");
}
echo $filetype;

Out of my head, however it's all at php.net. Go there and embrace the php goodness.
