From: mpn at illearth dot net Operating system: Win NT(2K) PHP version: 4.3.9 PHP Bug Type: Output Control Bug description: headers_sent() reporting incorrect value
Description: ------------ When checking the value of headers_sent(), function is returning FALSE even though headers have clearly been sent. Returned result does not change when output buffering is commented out or where output buffering is started (i.e before sending headers or after ). I crammed the test code into 19 lines, so please excuse the formatting. ["SERVER_SOFTWARE"]=> string(31) "Apache/2.0.49 (Win32) PHP/4.3.9" using sapi Reproduce code: --------------- <?php ob_clean(); if ( stristr( $_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip' ) ) { ob_start( 'compressOutput' ); } else { ob_start(); } header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT' ); header( 'Cache-Control: no-store, no-cache, must-revalidate' ); header( 'Cache-Control: post-check=0, pre-check=0', FALSE ); header( 'Last-Modified: ' . gmdate( 'D, d M Y H:i:s' ) .
