Once the crypto settings are established, cryptography can be turned on and off dynamically by passing true or false in the parameter. enable

     If omitted, the  context option on

session_stream Seed the stream with settings from . session_stream

Returns true on success, false if negotiation has failed or if there isn't enough data and you should try again (only for non-blocking sockets). 0

Voorbeeld: example

<?php
$fp = stream_socket_client("tcp://myproto.example.com:31337", $errno, $errstr, 30);
if (!$fp) {
    die("Unable to connect: $errstr ($errno)");

/* Turn on encryption for login phase */

fwrite($fp, "USER god\r\n");
fwrite($fp, "PASS secret\r\n");

/* Turn off encryption for the rest */
stream_socket_enable_crypto($fp, false);

while ($motd = fgets($fp)) {
    echo $motd;
}

fclose($fp);
