how protect external javascript using PHP

**M rosi** · 07-26-2010, 04:14 PM

hi,

I want to protect my external javascript(and css also) from outside people, who steal my javascript.

but this is impossible using client-side language.

so can anyone tell me a method to hide external javascript(and css) by using sever-side language???

thank you

I found some code. but it' not working
the code witch i want to protect

Code:

<html>
<head>
<title>Test</title>

<link rel="stylesheet" type="text/css" href="Excss/css_test.css">   //external css in the folder of Excss
<script type="text/javascript" src="Exjs/js_test.js" ></script>  //external js in the folder of Excss
</head>
<body>
</body>
</html>

then the new code....

Code:

<html>
<head>
<title>Test</title>

<link rel="stylesheet" type="text/css" href="hide.php?type=css&serve=css_test"/>
<script type="text/javascript" src="hide.php?type=js&serve=js_test"> </script>

</head>
<body>
</body>
</html>

hide.php

Code:

<?php
if (defined('IN_SITE'))
{
    $sPath = '';
    switch(@$_GET['type'])
    {
        case 'css':
            header('Content-type: text/css');
            $sPath = 'Excss/' . @$_GET['serve'] . '.css';
            break;
        case 'js':
            header('Content-type: text/js');
            $sPath = 'Exjs/' . @$_GET['serve'] . '.js';
            break;
    }

    // sPath should be a non-published directory
    $fp = @fopen($sPath, 'r');
    if ($fp)
    {
        fpassthru($fp);
        fclose($fp);
    }
}

?>

why is this not working? can anyone correct this code.....?

That's not going to hide the code or protect it. The user just needs the variables which are and have to exposed in your code.

Anyway if you want to do it the way your doing it can you post a link or the directory structure, just note that it is not anymore secure than linking to the regular css file.

or you could try

Code:

<?php
if (defined('IN_SITE'))
{
    $sPath = '';
    @switch($_GET['type'])
    {
        case 'css':
            header('Content-type: text/css');
            $sPath = "Excss/$_GET['serve'].css";
            break;
        case 'js':
            header('Content-type: text/js');
            $sPath = "Exjs/$_GET['serve'].js";
            break;
    }
    // sPath should be a non-published directory
    $fp = @file_get_contents($sPath);
    if ($fp) {
       echo $fp; 
    }
}
?>
