@ShrineDesignsJul 02.2004 — try the pathinfo() function, example:[code=php]<?php
$path_parts = pathinfo("/www/htdocs/index.html");

echo $path_parts["dirname"]."n";
echo $path_parts["basename"]."n";
echo $path_parts["extension"]."n";
?>[/code]

@crh3675Jul 02.2004 — How about just:

[code=php]
<?
$file="http://www.somesite.com/farms/horses.pdf";

function getExtension($f){
$parts=explode(".",trim($f));
return strtoupper($parts[count($parts)-1]);
}

print getExtension($file);
?>

[/code]

@moondanceJul 03.2004 — or how about a simpler alternative:

[code=php]
Function GetExtension($filename)
{
return strrchr($filename, ".");
}
[/code]

strrchr looks for the last occurence of a character in a string, so this would work ok for extensions that are 2 or 4 characters long, as well as filename such as "my.pic.jpg"

Success!
