Last time I checked, two consecutive "exec" calls with the same second argument would append to the array of outputs. Hey, it's even documented that way: http://www.php.net/manual/en/function.exec.php It was unexpected when I first saw it, but seemed perfectly sane to me, as I suppose somebody might want it, and unset($output); wasn't exactly horrible to add before each "exec" call. It would be wise to check other PHP function with references returned to sanity check your definition of sane :-) -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE
