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

ID: 41491 Updated by: tony2001@php.net Reported By: jeff at pointhere dot net -Status: Open +Status: Bogus Bug Type: HTTP related Operating System: Sun OS 5.10 (Solaris 10) PHP Version: 5.2.2 New Comment: . Previous Comments: ------------------------------------------------------------------------ [2007-05-27 22:18:09] jeff at pointhere dot net THAT DID IT!! I then started experimenting with the code - I took out all of the code that had any variables and it worked. As soon as I added them in it did not. Then I changed the code to work with apostrophes rather than quotes and put the variables back in with a concatonation and it worked! I hope this makes sense and leads to a fix using the quotes and replacable variables. This code works as expected and you can color me thrilled: // Start sending the file ob_start(); header('Pragma: public'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Content-Type: text/plain'); header('Content-Disposition: attachment; filename="'.$filename.'"'); header('Content-Transfer-Encoding: 7bit'); echo($cardprint_file); ob_end_flush(); Thank you so much for pointing me down the path that led me to a work-around and a working program!!! Jeff ------------------------------------------------------------------------ [2007-05-27 17:50:20] iliaa@php.net Can you try leaving header() calls with static parameters (no embeded variables) and see if you still get the extra chars? ------------------------------------------------------------------------ [2007-05-24 15:50:34] jeff at pointhere dot net 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 this bug report at http://bugs.php.net/?id=41491&edit=1
