My PHP file/browser just frozed
<p>Okay i'm just starting out on PHP &amp; i'm doing the tutorials on the PHP manuals. After doing the first part.. which is echo hello world!, my browser just frozed? I refresh and all it says is Hello World! Even if I echo another word. Why doesn't it change?</p>

<p>and i'm also using Wamp for my PHP.</p>
