#41491 [NEW]: header() adds extra x'200A' space/LF to start of file

From: jeff at pointhere dot net Operating system: Sun OS 5.10 (Solaris 10) PHP version: 5.2.2 PHP Bug Type: HTTP related Bug description: header() adds extra x'200A' space/LF to start of file Description: ------------ When using the header() function to prepend a text file so that a user can save a downloaded file, the resulting file has two extra characters on the front of the file (hex '200A' - space and line-feed). When header() functions are removed, the file appears to load into the browser correctly. Reproduce code: --------------- // Start sending the file ob_start(); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private", false); header("Content-Type: text/plain"); header("Content-Length: " . $filesize); header("Content-Disposition: attachment; filename=\"" . $filename . "\""); header("Content-Transfer-Encoding: 7bit"); echo($cardprint_file); ob_end_flush(); exit; Expected result: ---------------- The user's browser should open a window that asks to Open, Save or Cancel the download. When saving or opening the file the contents of $cardprint_file should be the ONLY contents (the contents were verified to be correct with the var_dump command). Actual result: -------------- The first two characters in the file (which translate to a blank line) are an ASCII hex 20 (space) and an ASCII hex 0A (Line feed). -- Edit bug report at http://bugs.php.net/?id=41491&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41491&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41491&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41491&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41491&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41491&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41491&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41491&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41491&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41491&r=support Expected behavior: http://bugs.php.net/fix.php?id=41491&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41491&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41491&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41491&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41491&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41491&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41491&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41491&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41491&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41491&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41491&r=mysqlcfg
