I have a big(=many lines) function "a()" and a little one "b()". I call function "b()" from function "a()" and alsow from many other php files.

That's why I don't want to use b($var_a). > -- > Jason Wong -> Gremlins Associates -> www.gremlins.com.hk > Open Source Software Systems Integrators > * Web Design & Hosting * Internet & Intranet Applications Development * > > /* > "I will make no bargains with terrorist hardware." > -- Peter da Silva > */ Best regards, George Nicolae IT Manager ___________________ PaginiWeb.com - Professional Web Design www.PaginiWeb.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
