PHP Installation

Tadreeb LMS supports PHP 8.2 only. Other PHP versions are not recommended and may lead to unexpected issues.

Supported PHP Version​

Note

Before installing PHP, ensure that your system meets the
System Requirements.

  • PHP 8.2 – Required and officially supported

PHP must be installed for:

  • The web server (Apache)
  • The command-line interface (CLI)

⚠️ Both Apache and CLI must use the same PHP version (8.2).

Required PHP Extensions​

The following PHP extensions must be installed and enabled for Tadreeb LMS to function correctly:

  • php8.2 – Core PHP 8.2 package
  • php8.2-cli – Command-line interface for PHP
  • php8.2-common – Common PHP files
  • php8.2-mbstring – Multibyte string support
  • php8.2-xml – XML support (DOM, SimpleXML, XMLReader/Writer)
  • php8.2-curl – cURL support for HTTP requests
  • php8.2-zip – ZIP archive support
  • php8.2-mysql – MySQL/MariaDB drivers (MySQLi & PDO)
  • php8.2-bcmath – Arbitrary precision mathematics
  • php8.2-gd – Image processing (GD library)

These extensions are installed through standard OS packages, for example:

  • php8.2-mysql
  • php8.2-xml
  • php8.2-mbstring

✅ No additional database connector configuration is required beyond installing the PHP MySQL extension.

Verifying Installed Extensions​

To confirm that a PHP extension is enabled, run:

php -m | grep -i <extension_name>

If the extension name appears in the output, it is enabled.

PHP Configuration (php.ini)​

The following php.ini values must be configured for Tadreeb LMS:

memory_limit = 512M
upload_max_filesize = 512M
post_max_size = 512M
max_execution_time = 300
max_input_time = 300
max_input_vars = 5000
date.timezone = UTC

These settings are required to:

  • Prevent installer timeouts
  • Allow large file uploads
  • Ensure stable request processing

ℹ️ Values can be increased further based on project requirements.

Notes on PHP Configuration​

Multiple php.ini Files​

PHP uses different configuration files depending on how it is executed.

Common locations on Ubuntu:

  • Apache
    /etc/php/8.2/apache2/php.ini

  • CLI
    /etc/php/8.2/cli/php.ini

Ensure that the required configuration values are applied consistently in both files.

Identify Active Configuration​

  • For CLI:

    php --ini

  • For Web:

    • Use a phpinfo() page, or
    • Check the Apache PHP handler configuration

Restart Services​

After installing PHP extensions or modifying php.ini, restart Apache:

sudo systemctl restart apache2

✅ PHP is now correctly configured for Tadreeb LMS.
