The ionCube PHP Encoder makes it easy to protect your PHP files from easy observation, theft and change. With optional licensing features built in, licensing your scripts to control which server your code runs on is easy too, and you can even give your files a time expiry!

Available in three versions, Basic, Pro and Cerberus, all versions offer bytecode PHP encoding plus optional encryption of non-PHP files. Pro and Cerberus also include the optional PHP licensing features for time expiry and restricting where code can be used, allowing licensing models to be effectively and easily implemented.

The PHP Encoder is available for Windows, Linux, FreeBSD and Intel OS X. All versions offer command line access for encoding and creating license files (Pro and Cerberus), which is ideal if you wish to automate processing. The Windows Encoder also includes an easy to use GUI, and the Windows Pro and Cerberus version includes a Linux based license generator for PHP scripts for FREE, which is great if you wish to encode on Windows and create license files from a Linux based web server for example.

Encoded files run on a wide range of operating systems such as Linux, Windows, FreeBSD and more.

Encoding BenefitsAs PHP scripts can be easily read, changed and run on any PHP enabled system, encoding PHP offers important benefits:

Product Developers: protect and license your code before distribution. Ideal for protecting evaluation copies, the low once only purchase cost can quickly deliver a significant return on investment from increased sales.

Website Designers: protect your creative work and a revenue stream from future script updates.

Enterprise Customers: successfully enforce internal change control policies by avoiding untracked software tweaks that may get lost on a site reinstall or server move.

Website Owners: hide sensitive data and protect scripts from unauthorised changes that may go unnoticed indefinitely and be a serious security and data protection risk.
