Manipulate a string...

[Anon]

Okay... here's the next hurdle..

I need to use regular expressions or something for this one but can't work it out myself...

I have a filename that takes the form:

www.somedomain.com.gif (or jpg, or png)

basically a url then the image file extension.

I want to end up with the url as a variable (let's call it $url if that's okay)

so I can print a string that looks like this:

<A HREF="$url"><IMG SRC="$filename" ALT="Visit $url"></A>

[craigh]

$string = "www.somedomain.com.gif"

$extension = substr($string, -4)

$url = substr($string, 0, (strlen($string)-4))

I think this will work. I didn't test it. Of course, this only works if all your extensions are four characters long (a dot plus three characters).
