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

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. =)

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.

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);
