How can PHP 4.x users adapt the method of passing variables to class constructors used in PHP 5?

In PHP 4.x, class constructors do not support passing variables directly. To adapt to the method used in PHP 5, PHP 4.x users can create setter methods within the class to set the values of the variables after the object has been instantiated. 

class MyClass {
    private $variable;

    public function __construct() {
        // Constructor in PHP 4.x
    }

    public function setVariable($value) {
        $this->variable = $value;
    }
}

// Instantiate the class and set the variable
$obj = new MyClass();
$obj->setVariable('value');
