Hi Leo,
Actually I do this with preg_replace().
A code might like this:
--- begin code ---
// if url taken from browser url address
$querystring = $_SERVER['QUERY_STRING'];
$newurl = preg_replace('/(var1)=([0-9].*)&(.*)$/', '\1=20&\3',
$querystring );
// if url taken from string
$url = http://www.foo.com/test.php?var1=20&var2=10
list(, $querystring) = explode('?', $url);
$newurl = preg_replace('/(var1)=([0-9].*)&(.*)$/', '\1=20&\3',
$querystring );
--- end code ---
Good Luck,
Firman
