As it is the same as this: if( ! ( isset($argv[1]) && isset($argv[2]) && isset($argv[3]) ) ) Which most of us write if (!isset($argv[1]) || !isset($argv[2]) || !isset($argv[3])) All three have the same result ;) Tijnema -- Vote for PHP Color Coding in Gmail! -> http://gpcc.tijnema.info -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
