stream_socket_shutdown — Shutdown a full-duplex connection
$stream
, int $how
) : boolShutdowns (partially or not) a full-duplex connection.
Note:
The associated buffer, or buffers, may or may not be emptied.
streamAn open stream (opened with stream_socket_client(), for example)
how
One of the following constants: STREAM_SHUT_RD
(disable further receptions), STREAM_SHUT_WR
(disable further transmissions) or
STREAM_SHUT_RDWR (disable further receptions and
transmissions).
成功时返回 TRUE， 或者在失败时返回 FALSE。
Example #1 A stream_socket_shutdown() example
<?php
$server = stream_socket_server('tcp://127.0.0.1:1337');
$client = stream_socket_client('tcp://127.0.0.1:1337');
var_dump(fputs($client, "hello"));
stream_socket_shutdown($client, STREAM_SHUT_WR);
var_dump(fputs($client, "hello")); // doesn't work now
?>
以上例程的输出类似于：
int(5) Notice: fputs(): send of 5 bytes failed with errno=32 Broken pipe in test.php on line 9 int(0)
Just a note to say that if you encounter problem closing some sockets using fclose in a multi client server, you should really give this one a try.
Spent a full day trying to resolve this issue using stream_socket_shutdown($clientStream,STREAM_SHUT_RDWR);
finally do the trick.
