What are the best practices for using constructors in PHP classes?

When using constructors in PHP classes, it is best practice to set initial values for class properties, perform any necessary setup tasks, and handle any dependencies that the class may have. This ensures that the class is properly initialized and ready to be used. 

class MyClass {
    private $property;

    public function __construct($value) {
        $this->property = $value;
        // Perform any additional setup tasks here
    }

    public function getProperty() {
        return $this->property;
    }
}

// Usage
$myObject = new MyClass('Initial value');
echo $myObject->getProperty(); // Output: Initial value
