Bug #65943 [Opn->Csd]: Blank headers missing with apache_request_headers

Edit report at https://bugs.php.net/bug.php?id=65943&edit=1 ID: 65943 User updated by: jgotts at gmail dot com Reported by: jgotts at gmail dot com Summary: Blank headers missing with apache_request_headers -Status: Open +Status: Closed Type: Bug Package: Apache related Operating System: Linux PHP Version: 5.4.21 Block user comment: N Private report: N New Comment: I'm going to close this bug because it's a bug in XMLHttpRequest::setRequestHeader() in Firefox 24, not in PHP. PHP does the right thing when I explicitly set a blank header like this: curl -k -H "my-header;" https://127.0.0.1/test.php test.php: <?php print_r(apache_request_headers()); ?> Output: Array ( [User-Agent] => curl/7.27.0 [Host] => 127.0.0.1 [Accept] => */* [my-header] => ) Previous Comments: ------------------------------------------------------------------------ [2013-10-22 01:48:25] jgotts at gmail dot com Description: ------------ It appears that apache_request_headers won't return blank headers. The key for said header is missing from the associative array. We have something quite simple on the JavaScript side: var xhr = new XMLHttpRequest(); ... xhr.setRequestHeader('my-header', ''); Nothing in https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest disallows a blank second argument for setRequestHeader(). And on the PHP side, we have: $headers = apache_request_headers(); $headers['my-header'] is missing! What ate it? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65943&edit=1
