Here's the thing.. I have a file named first.php containing the following code:
<html>
<title>trial</title>
<head>welcome</head>
<body>
<br>
<?php
echo "hello world";
?>
</body>
</html>
However when I execute it, the php code is not interpreted. The short open tag also seems to be on. I'm using wampserver. what have I missed?
