KasperskyOS modification of PHP Interpreter

This version of PHP Interpreter (Zend) is adapted for KasperskyOS. The PHP Interpreter operates in FastCGI mode.

What is a PHP Interpreter for KasperskyOS?

The PHP Interpreter for KasperskyOS is based on the PHP-8.2. Please refer to README.md for more information about the original PHP Interpreter not related to this project.

The PHP Interpreter for KasperskyOS has the following limitations:

• Currently, subprocess creation isn't available in KasperskyOS Community Edition. All client requests to the PHP Interpreter are processed sequentially: a new request is executed only when a previous request has finished processing.

For additional details on KasperskyOS, including its limitations and known issues, please refer to the KasperskyOS Community Edition Online Help.

Getting started

Prerequisites

1. Install KasperskyOS Community Edition SDK. You can download the latest version of the KasperskyOS Community Edition for free from os.kaspersky.com. The minimum required version of KasperskyOS Community Edition SDK is 1.2. For more information, see System requirements.
2. Copy project sources files to your home directory. All files that are required to build the PHP Interpreter for KasperskyOS and examples of KasperskyOS-based solutions are located in the following directory:

   ./kos
   

3. Set the environment variable SDK_PREFIX to /opt/KasperskyOS-Community-Edition-<version>, where version is the version of the KasperskyOS Community Edition SDK that you installed. To do this, run the following command:

   $ export SDK_PREFIX=/opt/KasperskyOS-Community-Edition-<version>
   

Building the PHP Interpreter

Run the following script to build the PHP Interpreter for KasperskyOS:

./kos/php/cross-build.sh

The PHP Interpreter for KasperskyOS is built using the CMake build system, which is provided in the KasperskyOS Community Edition SDK.

Installing and removing the PHP Interpreter

To install the PHP Interpreter for KasperskyOS to the KasperskyOS Community Edition SDK, run the following script with root privileges:

./kos/php/install.sh

To remove the PHP Interpreter for KasperskyOS from the KasperskyOS Community Edition SDK, run the following script with root privileges:

./kos/php/uninstall.sh

Usage

When you develop a KasperskyOS-based solution, use the recommended structure of project directories to simplify usage of CMake scripts.

To include the PHP Interpreter in your KasperskyOS-based solution, follow these steps:

1. Add the find_package() command to the ./CMakeLists.txt root file to find and load the php package.

   find_package (php REQUIRED)
   

   For more information about the ./CMakeLists.txt root file, see the KasperskyOS Community Edition Online Help.
2. Add the Fpm program to a list of program executable files defined in the ./einit/CMakeLists.txt file as follows:

   set (ENTITIES
        Fpm
        ...)
   

   For more information about the ./einit/CMakeLists.txt file for building the Einit initializing program, see KasperskyOS Community Edition Online Help.
3. Specify a list of IPC channels that connect the Fpm program to VfsNet and VfsRamFs programs in the ./einit/src/init.yaml.in template file. For more information about the init.yaml.in template file, see KasperskyOS Community Edition Online Help.
4. Create a solution security policy description in the ./einit/src/security.psl.in template file. For more information about the security.psl.in template file, see KasperskyOS Community Edition Online Help.
5. Add PHP and nginx configuration files to the directory ./resources.

Examples

• ./kos/examples/fpm—Version of the FastCGI Process Manager (FPM) adapted for use on KasperskyOS.
• ./kos/examples/web_server—KasperskyOS-based dynamic web server.

Testing the PHP Interpreter

The test suite for the original PHP Interpreter is used to test the PHP Interpreter for KasperskyOS, but testing systems are different. The testing system for KasperskyOS consists of two programs: php.Server and php.Client. The php.Client program parses PHPT files and sends a request, which contains a PHP script, to the php.Server program. The php.Server program executes the request and returns а result to the php.Client using аn HTTP response. The php.Client compares the received response with the expected result.

To run the tests, execute the following script:

./kos/tests/cross-build.sh

If you want to save test results to a file, go to the directory ./kos/tests and run the following command:

./cross-build.sh > log.txt
