(PHP 4 >= 4.2.0, PHP 5, PHP 7)
Sets blocking mode on a socket resource
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.
Parameters:
socket
A valid socket resource created with socket_create() or socket_accept().
Returns:
Returns TRUE
on success or FALSE
on failure.
Examples:
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.
