How To Hide Your JavaScript With PHP!
by Ben SinclairI hate the thought of JavaScript that you don't want to be copied being copied... Here's a little script that will hide it so that no one can copy it!
The Script
On the page where the JavaScript is placed, add:
<?
session_start();
if (!isset($_SESSION['access'])){
$_SESSION['access'] = true;
$access = true;
}
?>
<html>
<head>
<script language="JavaScript" src="script.php"></script>
</head>
<body>
Body goes here...
</body>
</html>
session_start();
if (!isset($_SESSION['access'])){
$_SESSION['access'] = true;
$access = true;
}
?>
<html>
<head>
<script language="JavaScript" src="script.php"></script>
</head>
<body>
Body goes here...
</body>
</html>
And now create a new file called script.php and place your JavaScript there:
<?
session_start();
if($access)
{
header("Content-type: text/javascript");
?>
//any javascript can go in here
alert("woohoo it works at last!");
<?
$access = false;
}
?>
session_start();
if($access)
{
header("Content-type: text/javascript");
?>
//any javascript can go in here
alert("woohoo it works at last!");
<?
$access = false;
}
?>
As you can see it uses a session. When you open the page where the JavaScript is placed it creates a session which allows the JavaScript to be viewed. But if you open script.php by its self, no session is created!
Try opening script.php in your browser window and you'll notice you can't view the code!
Enjoy!
