How can redundant method calls be optimized in PHP when instantiating classes within a switch case?

Redundant method calls can be optimized in PHP when instantiating classes within a switch case by using a variable to store the instantiated object and then calling methods on that object. This prevents unnecessary instantiation of the same class multiple times within the switch case. 

$classInstance = null;

switch ($type) {
    case 'A':
        if ($classInstance === null) {
            $classInstance = new ClassA();
        }
        $classInstance->method();
        break;
    case 'B':
        if ($classInstance === null) {
            $classInstance = new ClassB();
        }
        $classInstance->method();
        break;
    default:
        // Handle default case
        break;
}
