title: What is <<<_END?
body: <p>I'm new to PHP and don't understand what the point of <code>&lt;&lt;&lt;_END</code> is. Could someone please explain when this should be used? I've looked at various examples and they all seem to have HTML embedded within them. But I can use HTML without the <code>&lt;&lt;&lt;_END</code> tags, so why should I use them? I tried searching the manual, but I keep finding the <code>end()</code> method for arrays.</p>
