How can developers effectively handle complex PHP scripts with multiple functions and dependencies?

Developers can effectively handle complex PHP scripts with multiple functions and dependencies by organizing their code into smaller, more manageable modules or classes. They can also use namespaces to prevent naming conflicts and improve code readability. Additionally, utilizing autoloading mechanisms such as Composer can help streamline the loading of dependencies. 

// Example of organizing code into classes and using namespaces

namespace MyNamespace;

class ClassA {
    public function methodA() {
        // Functionality for methodA
    }
}

class ClassB {
    public function methodB() {
        // Functionality for methodB
    }
}

// Implementing autoloading with Composer
require 'vendor/autoload.php';

// Start using the classes
$classA = new MyNamespace\ClassA();
$classA->methodA();

$classB = new MyNamespace\ClassB();
$classB->methodB();
