Prevent Reverse Engineering and Unauthorized Use
With Zend Guard, you can encode, obfuscate and protect your PHP code to prevent unlicensed use and reverse engineering.
Zend Guard supports PHP versions up through 5.6. Please read this blog for more information.

With Zend Guard, developers can encode their PHP script at any time during the development process, protecting PHP code prior to distribution or publishing.
You can prevent external code tampering by using obfuscation in Zend Server. It converts tags and names in code files into cryptic names. As a result, external parties will not be able to easily understand your code, yet your applications will run successfully.
Choose a license model that meets your requirements. Options include number of concurrent users or specific amounts of time, network segments, or servers.
You worked hard to develop your code. Now you need to protect it. Zend Guard's powerful encoding and obfuscation technologies prevent reverse engineering, copyright infringement, and unauthorized modification of your code.
Encoding is a process where the PHP source code is converted to an intermediate machine readable format, just like PHP encryption. This format is hard for humans to read and convert back to source code. As a result it protects your code from casual browsing. This means that if people obtain access to your site's code they will not be able to use that for unintended purposes.
Obfuscation is a process where the code is intentionally made very hard to read as source code or as reverse engineered code. This obfuscation is designed to manage risks that stem from unauthorized access to source code. These risks include loss of intellectual property, ease of probing for application vulnerabilities and loss of revenue that can result when applications are reverse engineered, modified to circumvent licensing and then recompiled. Although reverse engineering always existed in computer software, it is especially important for in computing environments such as PHP which take advantage of dynamic processing of language elements rather than code which has been compiled into machine language before being deployed.
Zend Guard's licensing capabilities allow Independent Software Vendors to create a variety of licensing policies for their commercial PHP applications. The product supports most commonly used licensing models such as concurrent users, time limited, segment of network, or server specific licensing. These capabilities allow vendors to maximize their revenue by preventing unauthorized use.
Compiles and converts the plain-text PHP scripts into a platform-independent binary format known as a 'Zend Intermediate Code' file. These encoded binary files can then be distributed instead of the plain text PHP protecting your hard programming efforts. Benefits of using this PHP encrypt process:
The Zend Guard License Manager both strengthens protection and enhances revenue generation opportunities.
Choose from a variety of licensing models such as concurrent users, time limited, segment of network, or server specific.
The license file, deployed along with the encoded PHP, is validated at runtime. Licenses can be easily modified or renewed, without the need to deploy new software. Vendors can pick-and-choose from a variety of flexible licensing models:
Full support for PHP 5.5 and 5.6.
Full support for PHP 5.4.
