phpでこういう書き方もできる

<?php
header("Content-type:application/x-javascript");

echo "(function(){";

require_once 'require/spanFontController.js';
require_once 'require/ContainerSlider.js';
require_once 'require/LinkController.js';
require_once 'require/Main.js';

echo <<<EOF

function init(){
	new Main();
}

document.addEventListener('DOMContentLoaded',init,false);
EOF;

echo "}());";
?>
