How can the Adapter Pattern be used to address issues with method declaration differences in PHP classes?

The Adapter Pattern can be used to address issues with method declaration differences in PHP classes by creating an adapter class that acts as a bridge between the incompatible classes. The adapter class implements a common interface that both classes can use, allowing them to work together seamlessly. 

// Interface that both classes will implement
interface TargetInterface {
    public function commonMethod();
}

// Class with different method declaration
class Adaptee {
    public function specificMethod() {
        echo "Specific method called\n";
    }
}

// Adapter class that implements the common interface
class Adapter implements TargetInterface {
    private $adaptee;

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

    public function commonMethod() {
        $this->adaptee->specificMethod();
    }
}

// Client code
$adaptee = new Adaptee();
$adapter = new Adapter($adaptee);
$adapter->commonMethod();
