This works differently in 5.2.6 and 5.2.8. I've scanned through UPDATING/CHANGELOG but couldn't find anything. I've disabled APC to make sure it's not connected. php -m: [PHP Modules] ctype date dom filter iconv libxml mbstring mcrypt mysqli pcre Reflection session SimpleXML sockets SPL standard tidy xml zlib Also reproduced with RC1 on 5.3: PHP 5.3.0RC1 (cli) (built: Apr 9 2009 15:45:09) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies Reproduce code: --------------- <?php ob_start(); system('file -i -b /path/file.txt'); $contents = ob_get_contents(); ob_end_clean(); var_dump(headers_sent($file, $line), $file, $line); Expected result: ---------------- headers_sent() should return false. Actual result: -------------- headers_sent() returns true, with empty $file and $line = 0. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47937&edit=1
