Examples
Example #1 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.
