说明

bool socket_set_nonblock ( resource $socket )

The socket_set_nonblock() function sets 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 non-blocking socket, the script not pause its execution until it receives a signal or it can perform the operation. Rather, if the operation would result in a block, the called function will fail.

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_nonblock() example


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

socket_accept($socket);
?>

This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_NONBLOCK mode. socket_accept() will immediately fail unless there is a pending connection exactly at this moment.
