<?php
if (false == ($socket = @socket_create(AF_INET, SOCK_STREAM, SOL_TCP))) {
   echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}

if (false == (@socket_bind($socket, '127.0.0.1', 80))) {
   echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($socket)) . "\n";
}
?>
