extension grab

[chrisleon]

I would like to find a way to grab the extension of a file that I am linking.

ie.

<a href="worddoc.doc">Some word file</a>
<a href="pdfdoc.pdf">Some adobe file</a>

and grab the .doc or .pdf file extension.

Is this a semi-easy task?

I have done something similar with getting the text that sits in between the <title> tags but that doesn't seem to apply to this example.

If someone can point me in the right direction, I would appreciate that.

Hi,

When you say 'grab', do you mean you have a string ...

<?php
$html = '
<a href="worddoc.doc">Some word file</a>
<a href="pdfdoc.pdf">Some adobe file</a>
';
?>

... and you want to extract just the extensions of all the urls referred to in the href's?

P.

PS Look up preg_replace() in the manual.
