How can PHP beginners effectively transition from using functions to classes for their scripts?

To effectively transition from using functions to classes for PHP scripts, beginners should start by identifying common functionalities that can be grouped together into classes. They can then create classes with methods that perform these functionalities, making the code more organized and reusable. By gradually converting functions into class methods, beginners can improve their understanding of object-oriented programming in PHP.

// Example code snippet demonstrating the transition from functions to classes

// Function-based approach
function greet($name) {
    echo "Hello, $name!";
}

greet("John");

// Class-based approach
class Greeting {
    public function greet($name) {
        echo "Hello, $name!";
    }
}

$greeting = new Greeting();
$greeting->greet("John");
