Getting last part of URL

[multimediocrity]

Ok, I'm stumped! I need to get the highest folder name in the URL, such as the examples below:

www.fakesite.com/folder/this
www.fakesite.com/folder/file/this/
www.fakesite.com/this/index.html

will all yield 'this'.

How do I approach this using PHP or JavaScript?

Thanks,
M

This seems to work, at least for those 3 test cases:

<?php
$test = array(
   'www.fakesite.com/folder/this',
   'www.fakesite.com/folder/file/this/',
   'www.fakesite.com/this/index.html'
);
foreach($test as $string) {
   if(preg_match('#/([^./]+)(/(.+\..+)?)?$#', $string, $matches)) {
      echo "<p>".$matches[1]."</p>\n";
   }
}

Well... thanks! That was very thorough. That did what I needed it to do. I don't think there's a rule or a 'best practice' in this case. Thanks for the solution!

Glad it helped. I have to admit upon looking at it again, the regexp sure looks arcane, or else like random typing with the shift key held down.

I know! And I thought PHP had enough arbitrary punctuations before I saw this! Thanks again, though. It works well from what I tested.
