I am parsing the following string from a previous page using POST .

folder/subfolder/images/imagename.jpg

to create a link to the image.

I also need to display on the page only the imagename.

How can I remove everything before the imagename and the .jpg file extention?

Use basename($path) to get the last path component.

Thanks, coddie.  You may also be interested in urlencode() and urldecode() respectively, for encoding spaces and special characters for urls.

Cheers,
Sam

Cheers Sam,
Thanks for the advice, since my first enquiry and your reply, I have got 'right into' what one can do with strings ..... !

As a ASP coder, I didn't realise there were so many operations that one could perform on a string in PHP.

Learn something new everyday.

All the best

Yes, it seems there are almost too many sometimes.  My biggest gripe is that the arguments to all the string operators aren't always consistent.  Check the manual regularly :-)
