Free PHP Obfuscator

Update: The obfuscator download is not active anymore.

You may need to obfuscate your php code for security or licensing reasons. So the other third party cannot easily hijack your code for their own reasons. Obfuscated code is source or machine code that has been made difficult to understand for humans. So if you planning to sell your php script, make sure you obfuscated it for security and license reasons.

There are a lot of tools to obfuscating PHP script, 2 best tools on the net right now is IonCube Encoder and Zend Guard. But unfortunately they are not free, and you need to install IonCube loader or Zend Guard loader module on the server, so the obfuscated could read properly.

If you are developing small PHP project than i suggest you to use the free PHP Obfuscator instead using IonCube Encoder or Zend Guard. You can use PHP Obfuscator from Raizlabs, it is light and free. I love free software, and i bet you do too 🙂

Here is the sample:

getbrowser.php

function getBrowser()
{
    $u_agent = $_SERVER['HTTP_USER_AGENT'];
    $bname = 'Unknown';
    $platform = 'Unknown';
    $version= "";

    //First get the platform?
    if (preg_match('/linux/i', $u_agent)) {
        $platform = 'linux';
    }
    elseif (preg_match('/macintosh|mac os x/i', $u_agent)) {
        $platform = 'mac';
    }
    elseif (preg_match('/windows|win32/i', $u_agent)) {
        $platform = 'windows';
    }

    // Next get the name of the useragent yes seperately and for good reason
    if(preg_match('/MSIE/i',$u_agent) && !preg_match('/Opera/i',$u_agent))

    else {

    }

    // check if we have a number
    if ($version==null || $version=="") {$version="?";}

    return array(

        'version'   => $version,

}

// now try it

print_r($yourbrowser);
var_dump($ua);
