I'm trying to track down a strange issue -- everything works fine on both my development (localhost) systems and another remote server.

However in production (LightSpeed/PHP 5.4) it fails completely. Using a stripped-down version of the sample (exception handling omitted for brevity) even a simple version-check fails :

<?php
$userStoreHttpClient = new THttpClient('sandbox.evernote.com', '443', "/edam/user", 'https');
$userStoreProtocol = new TBinaryProtocol($userStoreHttpClient);
$userStore = new UserStoreClient($userStoreProtocol, $userStoreProtocol);
// do something simple and check the protocol version (returns true or false).
$versionOK = $userStore->checkVersion("Evernote EDAMTest (PHP)", 1, 21);
// <----- it never returns here. But gets stuck reading in ttransport.php
?>

I've been over the php.ini settings, cross-checked the firewall, and stepped through the lib files. It appears to get hung-up somewhere with the read.

I know it's not exactly an API issue, but has anyone seen this before?

Following up my own post -- It took a test box and a packet sniffer, but I think I figured this out.

Evidently the headers (as set by flush() in THttpClient.php) were being stripped and/or overidden on their way out.

Expecting the POST to arrive with the requisite "Content-Type: application/x-thrift", it was instead showing up as "ContentType: application/x-www-form-urlencoded"; not good.

As a hack, the following appears to be a workaround:

ini_set("user_agent", "PHP/THttpClient\r\nAccept: application/x-thrift\r\nContent-Type: application/x-thrift");

Piggybacking the user_agent gets us the other headers as a bonus.

The reasons for this still have me completely baffled, but I hope this helps anyone who might be troubleshooting the same thing.

BTW, the post at http://stackoverflow.com/a/4249933 pushed me in the right direction.

Mission accomplished. Your hack fixed my problem. Thanks.
