What are some recommended online tutorials for learning about classes in PHP?

One recommended online tutorial for learning about classes in PHP is the official PHP documentation on classes (https://www.php.net/manual/en/language.oop5.php). This tutorial covers the basics of creating classes, defining properties and methods, and instantiating objects. Another great resource is the PHP Classes and Objects tutorial on W3Schools (https://www.w3schools.com/php/php_classes.asp), which provides interactive examples and exercises to practice your skills.

<?php
class Person {
  public $name;
  public $age;

  public function __construct($name, $age) {
    $this->name = $name;
    $this->age = $age;
  }

  public function greet() {
    echo "Hello, my name is " . $this->name . " and I am " . $this->age . " years old.";
  }
}

$person1 = new Person("John", 30);
$person1->greet();
?>
