How does using objects as arrays in PHP provide a safer alternative?

Using objects as arrays in PHP provides a safer alternative because objects have access control modifiers like public, private, and protected, which can restrict access to properties. This helps prevent accidental modification of data and ensures that data is accessed and modified only through defined methods. Additionally, objects can have methods that validate input data before setting properties, adding an extra layer of security. 

class SafeArray {
    private $data = [];

    public function __get($key) {
        return $this->data[$key];
    }

    public function __set($key, $value) {
        // Add any validation logic here
        $this->data[$key] = $value;
    }
}

$safeArray = new SafeArray();
$safeArray->example = "Hello";
echo $safeArray->example; // Output: Hello
