SOCKET_SET_BLOCK(3) 1 SOCKET_SET_BLOCK(3)socket_set_block - Sets blocking mode on a socket resourceSYNOPSIS
bool socket_set_block (resource $socket)
DESCRIPTION
The socket_set_block(3) 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
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
socket_set_block(3) 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(3) will
hang until there is a connection to accept.

SOCKET_SET_NONBLOCK(3) 1 SOCKET_SET_NONBLOCK(3)socket_set_nonblock - Sets nonblocking mode for file descriptor fdSYNOPSIS
bool socket_set_nonblock (resource $socket)
DESCRIPTION
The socket_set_nonblock(3) 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 will not pause its execu-
tion 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.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
socket_set_nonblock(3) 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(3)
will immediately fail unless there is a pending connection exactly at this moment.
