One of the main threat PHP developers face is that PHP is an interpreted language, means PHP source code is readable by anybody who downloads your application. We can say that it’s a drawback of PHP. But you can protect your intellectual property by encoding your PHP source code. Here in this article I will explain how to protect your PHP source code.

Actually there are many tools available for protecting php code. But here we will discuss ionCude PHP encoder tool. By this tool, you can protect your PHP 4 & 5 source code from easy observation, theft and change. So before releasing your PHP software, you can use the encoder to convert your plain-text PHP files into special encrypted files.

The ionCude PHP Encoder is available for Windows, Linux, FreeBSD and Intel OS X. All versions offer command line access for encoding, and also for creating license files using Pro or Cerberus. This feature is ideal if you wish to automate processing. The Windows Encoder also includes an easy to use GUI, and the Windows Pro and Cerberus editions include a Linux based license generator for PHP scripts too, allowing scripts to be protected using Windows and creating license files from a Linux based web server.

How To Encode PHP source files
Here we will run a php script(phpencoder.php) for encoding its source code.  We will use below command to encode this file.
/usr/local/ioncube/ioncube_encoder5 phpencoder.php -o phpencoder-enc.php

<?php
   echo “MY PHP Encoder Example!”;
?>

You can also Encode an entire project directory by using below command:
/usr/local/ioncube/ioncube_encoder5 projectDir -o build
As There are are many different options available, encoding above script (phpencoder.php) with the default options will return following PHP file.

<?php
    echo(‘Site error: the file <b>’.__FILE__.‘</b> requires the ionCube PHP Loader ’.
    basename($__ln).‘ to be installed by the site administrator.’);
?>
