I would change the above the the following: if ( empty($pmatch) || ( strpos($key, $pmatch) === 0 ) ) { print "$key = $value<br />"; } it would be slightly faster

love the "skin the cat" game! What I like about this Jim is that the strpos() could be changed to allow a "contains" argument rather than a "begins with" argument... for example if you wanted to find all variable names containing 'foo'. Something like: if ( empty($pmatch) || (( strpos($tkey, $pmatch) === 0 ) || ( strpos($tkey, $pmatch) > 0 ))) { print "$key = $value<br />"; } t_foo foo_t t_foo_t would all be found. Thanks!
