String append

[jroscoe]

I have a variable:

$url = sprintf("%s%s%s","http://",$HTTP_HOST,"$REQUEST_URI?$url_params");

I want to create a new variable ($url_abbr) that only shows say the firs 50 characters of $url and then puts "..." at the end. How can I do this?

Thanks!

something like this...

$url_abbr = substr ($url, 0, 50)."...";
