PHP 4.0 Bug #8974: Blank lines in includes cause session errors

From: samj@faredge.com.au Operating system: All PHP version: 4.0.4pl1 PHP Bug Type: Feature/Change Request Bug description: Blank lines in includes cause session errors A PHP script with includes followed by commands which set headers (ie session_start) will generate errors if include file(s) contain blank lines. For example: <? include "includes/functions.inc"; session_start(); ?> where functions.inc contains leading or trailing blank lines will result in an error like: Warning: Cannot send session cache limiter - headers already sent This problem appears to be very common (according to a search on google), and has no doubt frustrated many PHP users. Unfortunately this behaviour is technically 'correct', although it should probably be fixed anyway. -- Edit Bug report at: http://bugs.php.net/?id=8974&edit=1
