Is it recommended to include the entire PHP code that needs to be processed within a constructor, or are there better practices for organizing code within classes?

It is not recommended to include the entire PHP code that needs to be processed within a constructor as it goes against the principle of separation of concerns and can lead to bloated and hard-to-maintain code. A better practice is to organize code within classes by breaking it down into smaller, more manageable methods and utilizing other class members like methods and properties to encapsulate functionality.

class MyClass {
    private $data;

    public function __construct($data) {
        $this->data = $data;
        $this->processData();
    }

    private function processData() {
        // Code to process data goes here
    }
}
