Just to avoid letting you search everywhere why your code doesn't work when using this function to enable crypto as a server, and when using TLS, you have to put the certificate in the "ssl" context, even if you start a TLS, SSLv3, etc.. server. I had some troubles because of that...

As already mentioned above: stream_socket_enable_crypto is likely to fail/return zero if the socket is in non-blocking mode. You may either wait some seconds until all neccessary data has arrived or switch temporary to blocking mode: <?PHP stream_set_blocking ($fd, true); stream_socket_enable_crypto ($fd, true, STREAM_CRYPTO_METHOD_TLS_CLIENT); stream_set_blocking ($fd, false); ?> This works very fine for me ;-)
