socket_set_block

SOCKET_SET_BLOCK(3)							 1						       SOCKET_SET_BLOCK(3)

socket_set_block - Sets blocking mode on a socket resource

SYNOPSIS

       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.
