Bug #4013: header function not functions after and if statment

From: everett@bentonrea.com Operating system: linux 2.2.5-15smp PHP version: 3.0.14 PHP Bug Type: Misbehaving function Bug description: header function not functions after and if statment Can some one explain this to me? $admin_test = admin_user($REMOTE_USER); if( !$admin_test ) { header("Location: index.phtml"); exit; } exit(); This is the problem portion of my code. If I run this code, and the $admin_test is false I get the "Warning Can't display more header info....." My initial thought was \n or \r in the function, but I have even changed the function to a simple return false; line. If $admin_test is true, then the page exits, and there is NOTHING that shows up when I do the View Source. If I remove the if statement, and just run the header function, like so: $admin_test = admin_user($REMOTE_USER); header("Location: index.phtml"); exit(); It works fine and redirects to that correct page. Any one have any ideas. Apache 1.3.11 PHP 3.0.14 mod_perl 1.21 mod_ssl.5.0 mod_auth_mysql 2.20 mysql 3.22.32 gd 1.7.3
