# socket_set_block

(PHP 4 >= 4.2.0, PHP 5)

socket_set_block — Sets blocking mode on a socket resource

### 설명

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.

### 인수

`socket`

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

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 예제

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.
