How do I determine the value of    tx   from this string?

Go regular expressions... /tx=([^\&]+)/ then do a preg_match with the string using the $matches array argument. $matches[1] should be your value. Ash www.ashleysheridan.co.uk

There really isn't a need to even try to build something like that when something already exists exactly for the purpose. It's well documented too. Plus after this part works, there's probably a good chance we'd be looking for that second variable. =) -- http://www.voom.me | EFnet: #voom

But isn't what you suggest to use only available in PHP5? When possible, I try to build for PHP4, as my own hosting, and others I've seen only support 4, and the old answer of "find a better hosting" is not always a good solution. Besides, if you need the second part of the URL, just adapt the regular expression a bit. I don't why people seem so afraid of them to be honest. Ash www.ashleysheridan.co.uk

parse_str (PHP 4, PHP 5) parse_str — Parses the string into variables

lol - it's obviously an url guys.. http://php.net/parse_url and http://php.net/parse_str $s = 'your/url/?with=parrams'; $parts = parse_url($s); $arrayOfQueryParams = parse_str($parts['query']); $theBitYouWant = $arrayOfQueryParams['tx']; // output the bit you want echo $theBitYouWant . PHP_EOL; // output all the params print_r($arrayOfQueryParams); regards
