Bug #77442 [NEW]: cURL ignores last header in CURLOPT_HTTPHEADER

From: stian at octetnest dot no Operating system: Ubuntu 16.04 PHP version: 7.1.26 Package: cURL related Bug Type: Bug Bug description:cURL ignores last header in CURLOPT_HTTPHEADER Description: ------------ cURL seems to always ignore the last header set through CURLOPT_HTTPHEADER. When I inspect outgoing requests with Wireshark, it consistently shows that the last header in an headers array provided to cURL gets ignored. For the headers provided in the 'Test Script' field, this is what Wireshark reports (The 'X-Remove' header is gone) : POST [REMOVED] HTTP/1.1 Host: [REMOVED] Accept: */* Accept-Encoding: application/xml X-External-User-ID: 1 X-Territory-ID: 9b0a8426-1493-4997-aab0-2d0de736225a X-Company-Name: Company Name X-File-Quality: 1 X-File-Type: JPG X-Filename-Prefix: prefix X-Title: Title Authorization: Basic dGVzdDp0ZXN0 X-Trace: 2B2B1AB863BA48CFF980DCE0B5CD3C3FE7DD4E68390B4A407CEEBFEBC601 If I take out the 'X-Remove' header, then cURL will ignore the 'Authorization' header. Test script: --------------- $headers = array( 'X-External-User-ID: 1', 'X-Territory-ID: 9b0a8426-1493-4997-aab0-2d0de736225a', 'X-Company-Name: Company Name', 'X-File-Quality: 1', 'X-File-Type: JPG', 'X-Filename-Prefix: prefix', 'X-Title: Title', 'Authorization: Basic dGVzdDp0ZXN0', 'X-Remove: This header will be removed by curl', ); $curl = curl_init(); curl_setopt_array($curl, array( CURLOPT_URL => $url, CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => "application/xml", CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 3, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => $method, CURLOPT_HEADER => 1, CURLOPT_HTTPHEADER => array_values($headers) )); -- Edit bug report at https://bugs.php.net/bug.php?id=77442&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77442&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77442&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77442&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77442&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77442&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77442&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77442&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77442&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77442&r=support Expected behavior: https://bugs.php.net/fix.php?id=77442&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77442&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77442&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77442&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77442&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77442&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77442&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77442&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77442&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77442&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77442&r=mysqlcfg
