Basic PHP skills for integrators

TYPO3

Beschreibung

TYPO3 integrators traditionally worked without needing PHP knowledge. That boundary has steadily blurred: configuration files, extension registration, and environment-specific setups all involve PHP that an integrator must be able to read and cautiously edit. This skill covers the foundational PHP concepts that appear most frequently in integrator work — from variables and arrays to conditional logic and functions — so that encountering a PHP file no longer means guesswork.

Ziele

• I know what a PHP variable is, how it is declared with the $ prefix, and what the common data types are (e.g strings, integers, booleans, arrays, and null) and how they appear in TYPO3 configuration files.
• I know what a PHP array is, can read both indexed and associative array structures as they appear in settings.php and additional.php, and know how arrays are merged using functions such as array_merge and the spread operator.
• I know what a return statement in a PHP file means and why TYPO3 configuration files use it to pass a data structure back to the system.
• I know what conditional statements are in PHP (e.g if, switch, and match) and can read conditional blocks in additional.php that apply different configuration depending on the application context or environment variables.
• I know what a function and a method are in PHP, can distinguish between a standalone function call and a method call on an object, and can identify both when reading TYPO3 configuration and extension files.
• I know what PHP namespaces are, how they are declared with the namespace keyword, and where they appear in TYPO3 extensions.
• I know how to read and make basic edits to settings.php and additional.php without breaking the file structure.
• I know how to register global Fluid ViewHelper namespaces in PHP so they are available across all Fluid templates without a per-file namespace declaration.
