Edit report at https://bugs.php.net/bug.php?id=79575&edit=1 ID: 79575 Updated by: cmb@php.net Reported by: kevin dot seymour at gmail dot com Summary: Content-Length header name is getting corrupted Status: Verified Type: Bug Package: OpenSSL related Operating System: * PHP Version: 7.3 Block user comment: N Private report: N New Comment: I'm not sure whether we prepare SSL correctly for this case. Previous Comments: ------------------------------------------------------------------------ [2020-05-11 08:00:11] nikic@php.net This is pretty weird. If the corrupted output comes from SSL_read(), then I don't think the problem here can be on the PHP side, right? ------------------------------------------------------------------------ [2020-05-09 13:32:50] cmb@php.net Apparently, the respective SSL_read() call[1] yields the broken contents. [1] <https://github.com/php/php-src/blob/php-7.3.17/ext/openssl/xp_ssl.c#L2099> ------------------------------------------------------------------------ [2020-05-08 16:59:35] kevin dot seymour at gmail dot com Description: ------------ When you run the below script you'll see the Content-Length header will come back with the correct value, but that the word Content is jumbled. For example: Cteonnt-Length: 195628. If you change Accept-Encoding to identity (disable compression) the value comes back correctly. This is causing unexpected end of data errors when we use SoapClient to attempt to parse a WSDL as only part of the XML is returned. There is a lot of testing information here: https://stackoverflow.com/questions/61681804/php-file-get-contents-returning-inconsistent-partial-data-for-http-requests Test script: --------------- php << 'EOF' <?php $ctx = stream_context_create(array( 'http' => array( 'header' => "Accept-Encoding: gzip" ) )); $xml = file_get_contents('https://webservices3.autotask.net/atservices/1.6/atws.wsdl', false, $ctx); echo var_dump($http_response_header); ?> EOF Expected result: ---------------- Content-Length should remain with the same header name. Actual result: -------------- Content-Length header field name is corrupted. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79575&edit=1
