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.

socket_accept - Accepts a connection on a socket

SYNOPSIS

       resource socket_accept (resource  $socket)

DESCRIPTION

	After  the socket $socket has been created using socket_create(3), bound to a name with socket_bind(3), and told to listen for connections
       with socket_listen(3), this function will accept incoming connections on that socket. Once a successful connection is made,  a  new  socket
       resource  is returned, which may be used for communication. If there are multiple connections queued on the socket, the first will be used.
       If there are no pending connections, socket_accept(3) will block until a connection becomes present. If $socket has been made  non-blocking
       using socket_set_blocking(3) or socket_set_nonblock(3), FALSE will be returned.

	The  socket  resource  returned by socket_accept(3) may not be used to accept new connections. The original listening socket $socket, how-
       ever, remains open and may be reused.

PARAMETERS

	      o $socket
		- A valid socket resource created with socket_create(3).

RETURN VALUES

	Returns a new socket resource on success, or FALSE on error. The actual error code can be retrieved by calling socket_last_error(3).  This
       error code may be passed to socket_strerror(3) to get a textual explanation of the error.
