Parameters on old PHP versions

I am trying to use two PHP commands on an older version of PHP that my web host is running (PHP/3.0); they work fine on my system that is running one of the final versions of v3, but on the web host, both give the error "Wrong parameter count" - the two commands are strpos() and fsockopen(). For reference the two program lines are: $fp = fsockopen($host, 80, &$err_num, &$err_msg, 30); and $adr = strpos("http://localhost/internal/send.php3","/" ,7); Any ideas? Did the spec of these two commands change during versions? Thanks in advance John -- // John Portwin <john@mobiletones.com> // Technical Director, mobiletones.com Ltd
