$arrayObj = new ArrayObject(['apple', 'banana', 'cherry']); $backupArray = $arrayObj->getArrayCopy();
$arrayObj1 = new ArrayObject(['apple', 'banana', 'cherry']); $arrayObj2 = new ArrayObject(['apple', 'orange', 'cherry']); if ($arrayObj1->getArrayCopy() == $arrayObj2->getArrayCopy()) { echo "The two arrays are the same."; } else { echo "The two arrays are different."; }In this example, two `ArrayObject` instances are created with different arrays of fruits. The `getArrayCopy()` method is called on both objects to create copies of their respective arrays. These copies are then compared using the `==` operator to determine if they are the same.
