MySQL Client/Server PHP problem

mysql 3.23.28 gamma PHP 4.0b4pl1 Apache 1.3.12 I have a PHP script that "include"s 1. a file that defines MySQL database constants, one of which is the HOST that the MySQL database is on, and 2. a file that contains a MySQL connection function. The main script "include"s both of these. In the database constants "include" file, after changing the DB_SERVER constant From: define("DB_SERVER","host_a"); To: define("DB_SERVER","host_b"); The "include"ed connection function still gets "host_a" as the value of the DB_SERVER constant. I can connect at the command line using "mysql" to "host_b" with no problem, and I can get my PHP script to connect to "host_b" if I hardcode host_b in the connect. I've tried bringing MySQL up on the client system(where the script runs) and issuing the "mysqladmin flush-hosts" command, which seems to work(comes back to the prompt), but every time DB_SERVER gets the value "host_a". Any ideas? TIA. -- Hardy Merrill Mission Critical Linux, Inc. http://www.missioncriticallinux.com
