Re: cvs: php-benchmarks / bench.php

It seems tha everyone is on-line and they've already provided great feedback. Let me just add that *ereg() and split() functions shouldn't be used. Please use the pcre extension instead. Also, take a look to the http://php.net/getopt function to simplify the code to parse command-line arguments.
