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.
