How should constructors be utilized in PHP classes and what are their main purposes?

Constructors in PHP classes are special methods that are automatically called when an object is created. They are used to initialize object properties or perform any setup tasks needed for the object to function properly. Constructors are defined using the `__construct` keyword in PHP classes. 

class Person {
    public $name;

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

$person = new Person('John Doe');
echo $person->name; // Output: John Doe
