how

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.
