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
?>
上例的输出类似于：
int(5) Notice: fputs(): send of 5 bytes failed with errno=32 Broken pipe in test.php on line 9 int(0)
