Try this, put your code in a file, say, testparse.php and testparsebracket.php and try something like myseq=`seq 1 1000` time for i in $myseq; do php testparse.php;done time for i in $myseq; do php testparsebracket.php;done of course the time to spawn php will probably be the most time consuming part Bret -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
