(PHP 5 >= 5.1.0, PHP 7)
stream_socket_enable_crypto — Turns encryption on/off on an already connected socket
说明
stream_socket_enable_crypto
( resource $stream
, bool $enable
[, int $crypto_type
[, resource $session_stream
]] ) : mixed
Enable or disable encryption on the stream.
Once the crypto settings are established, cryptography can be turned
on and off dynamically by passing true
or false
in the
enable
parameter.
参数
stream
The stream resource.
enable
Enable/disable cryptography on the stream.
crypto_type
Setup encryption on the stream. Valid methods are
STREAM_CRYPTO_METHOD_SSLv2_CLIENT
STREAM_CRYPTO_METHOD_SSLv3_CLIENT
STREAM_CRYPTO_METHOD_SSLv23_CLIENT
STREAM_CRYPTO_METHOD_ANY_CLIENT
STREAM_CRYPTO_METHOD_TLS_CLIENT
STREAM_CRYPTO_METHOD_TLSv1_0_CLIENT
STREAM_CRYPTO_METHOD_TLSv1_1_CLIENT
STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
STREAM_CRYPTO_METHOD_SSLv2_SERVER
STREAM_CRYPTO_METHOD_SSLv3_SERVER
STREAM_CRYPTO_METHOD_SSLv23_SERVER
STREAM_CRYPTO_METHOD_ANY_SERVER
STREAM_CRYPTO_METHOD_TLS_SERVER
STREAM_CRYPTO_METHOD_TLSv1_0_SERVER
STREAM_CRYPTO_METHOD_TLSv1_1_SERVER
STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
If omitted, the
crypto_method
context option on the stream's SSL context will be used instead.session_stream
Seed the stream with settings from
session_stream
.
返回值
Returns true
on success, false
if negotiation has failed or
0
if there isn't enough data and you should try again
(only for non-blocking sockets).

范例
Example #1 stream_socket_enable_crypto() 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 */stream_socket_enable_crypto($fp, true, STREAM_CRYPTO_METHOD_SSLv23_CLIENT);fwrite($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);?>
