What are the best practices for integrating self-written PHP scripts with Typo3?

To integrate self-written PHP scripts with Typo3, it is recommended to create Typo3 extensions to encapsulate your custom functionality. This allows for better organization, version control, and compatibility with Typo3's architecture. You can then call your PHP scripts within the extension using Typo3 hooks or by including them in your TypoScript configuration.

// Example Typo3 extension configuration file (ext_localconf.php)

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTypoScriptConstants('plugin.tx_myextension.settings.customScript = EXT:myextension/Resources/Private/PHP/customScript.php');

// Example Typo3 TypoScript setup file (setup.typoscript)

plugin.tx_myextension {
    settings {
        customScript = {$plugin.tx_myextension.settings.customScript}
    }
}
