How can PHP modules be effectively integrated into API scripts for functionality?

To effectively integrate PHP modules into API scripts for functionality, you can use the "require" or "include" statements to include the necessary module files in your script. This allows you to access the functions and classes provided by the modules within your API script, enabling you to leverage their functionality seamlessly.

// Include the necessary PHP module file
require_once 'module_file.php';

// Now you can use functions or classes from the module in your API script
// Example:
$result = ModuleClass::moduleFunction($param1, $param2);
