How can PHP developers effectively structure complex modules or programs to improve maintainability and reusability?

To effectively structure complex modules or programs in PHP for improved maintainability and reusability, developers can utilize object-oriented programming principles such as encapsulation, inheritance, and polymorphism. By breaking down the code into smaller, modular components with clear responsibilities, developers can easily maintain and reuse code in different parts of the application. 

<?php

// Example of structuring complex modules using object-oriented programming in PHP

// Parent class
class Module {
    protected $data;

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

    public function processData() {
        // Process data logic
    }
}

// Child class
class SubModule extends Module {
    public function processData() {
        // Additional processing logic specific to SubModule
    }
}

// Implementation
$data = ['example' => 'data'];
$module = new Module($data);
$module->processData();

$subModule = new SubModule($data);
$subModule->processData();

?>
