[SOLVED] regex

[Yesideez]

Having some major problems here.

preg_match('/^.*\/([^\/\.]*)\.\w{3,4}$/','http://www.mydomain.com/here.php',$filename);
echo print_r($filename);

This displays:

Array ( [0] => http://www.mydomain.com/here.php [1] => here ) 1

As you can see it extracts just the filename "here" into $filename[1] however, if I try this:

$str=$_SERVER['HTTP_REFERER'];
preg_match('/^.*\/([^\/\.]*)\.\w{3,4}$/',$str,$filename);
echo print_r($filename);

I get this instead:

1

 

Basically I'm trying to take any URL no matter whether it starts with ftp or http, regardless of the file extension and how many folders it's nested and only return the name of the file itself.

You could try doing an explode on "/", filtering out empty values, and then have a list of accepted file extensions and loop through the array until you find the entry that ends with one of the file extensions, (.php)

Found the reason I was getting nothing - I was calling that script directly and not linking to it!

<?php
$url = 'http://www.foo.com/1/2/3/4/foo.php';

$hash = count_chars($url, 1);
echo basename($url) . ' ' . ($hash[ord('/')] - 2);
?>

 

Might be a little faster than regex.

 

Best,
