How to encrypt php

Zend Guard

Zend Guard can only encrypt files with PHP tags or source code (such as: .php, inc, etc.), other files saved in text mode without PHP tag cannot be encrypted, support period, registration code. (Recommended learning: PHP programming from entry to proficiency)

Supports encryption of PHP4.2.X~5.2.X versions.

The ZendOptimizer (PHP engine) used can improve the speed optimization of the source code by more than 20~50%. Combined with ZendGuard, it can improve the performance speed optimization by more than 50%, and ZendOptimizer can be installed in many current mainstream systems.

(When using ZendGuard encryption, you can choose the ZendOptimizer version for more optimization). In addition, ZendGuard can only be used in an environment configured with ZendOptimizer and cannot run independently. (Must be configured in the php.ini file)

* Also worth noting is the error of ZendGuard under PHP4. There will be a big difference between the absolute path and relative path of PHP4 during encryption.

ionCube PHP Encode

ionCube PHP Encode, developed by ionCube, is used to encrypt PHP or non-PHP files. ionCube has been tested to be superior to Zend's ZendGuard in terms of functionality. It not only supports encryption methods such as expiration date, registration code, etc., but also supports complex encryption methods such as IP and MAC addresses.

In addition, ionCube can not only encrypt PHP files with PHP tags or source code, but also encrypt non-php files saved in text mode, such as xml, js, css, etc. (However, the read API provided by ionCube must be used for reading and writing operations.)

The encryptable PHP version ranges from PHP4.0.6~5.2.X (2 levels higher than ZendGuard)

Like Zend, ionCube also provides a corresponding PHP engine in order to improve PHP performance optimization, which can provide PHP optimization functions for most operating systems, but unfortunately, a Windows version of the PHP engine has not been provided so far.

Regarding the path problem in the PHP4 environment mentioned in ZendGuard before, it does not appear in ionCube. It can be seen that ionCube is relatively stable.

For ionCube, files with PHP tags or source code are processed by compression and encryption, and non-php text files are processed by encryption.

You must use "ioncube_read_file/ioncube_write_file" to read and write files when reading. Therefore, before using ionCube encryption, the corresponding PHP code needs to be modified before it can be used.
