Php Folks,
This is really weird!
Look at this code …
All tags intact but look at my attached img. Why php code is shown in Fire Fox ?
[code]
<!DOCTYPE html>
<html>
<head>
<title>Web Crawler in PHP</title>
</head>
<body>
<div id=”content” style=”margin-top:10px;height:100%;”>
<center><h1>Web Crawler in PHP</h1></center>
<form action=”index.php” method=”POST”>
URL : <input name=”url” size=”35″ placeholder=”http://www.subinsb.com”/>
<input type=”submit” name=”submit” value=”Start Crawling”/>
</form>
<br/>
<b>The URL’s you submit for crawling are recorded.</b><br/>See All Crawled URL’s <a href=”url-crawled.html”>here</a>.

What is wrong in the code ? What is misfiring in the browser ?
