socket_set_block

(PHP 4 >= 4.2.0, PHP 5)

socket_set_block — Sets blocking mode on a socket resource

说明

bool socket_set_block ( resource $socket )

The socket_set_block() function removes the O_NONBLOCK flag on the socket specified by the socket parameter.

When an operation (e.g. receive, send, connect, accept, ...) is performed on a blocking socket, the script will pause its execution until it receives a signal or it can perform the operation.

参数

socket: A valid socket resource created with socket_create() or socket_accept().

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

Example#1 socket_set_block() example


<?php
$socket = socket_create_listen(1223);
socket_set_block($socket);

socket_accept($socket);
?>

This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_BLOCK mode. socket_accept() will hang until there is a connection to accept.
