What are the benefits of separating the class definition from the main script in PHP development?

Separating the class definition from the main script in PHP development helps to organize the code, improve readability, and promote reusability. By defining classes in separate files, it becomes easier to maintain and update the codebase, as changes to the class do not affect the main script directly. Additionally, separating the class definition allows for better code modularization and can facilitate collaboration among developers working on different parts of the project. 

// File: MyClass.php
class MyClass {
    public function sayHello() {
        echo "Hello, World!";
    }
}

// File: main.php
require_once 'MyClass.php';

$myObject = new MyClass();
$myObject->sayHello();
