How does the use of return array() affect the output in PHP classes and methods?

Using `return array()` in PHP classes and methods will return an empty array. If you intend to return an array with specific values, you need to define those values within the `array()` function. To fix this issue, make sure to populate the array with the desired values before returning it. 

class MyClass {
    public function getArray() {
        // Populate the array with values before returning
        return array('value1', 'value2', 'value3');
    }
}

// Instantiate the class and call the method
$obj = new MyClass();
$result = $obj->getArray();

print_r($result); // Output: Array ( [0] => value1 [1] => value2 [2] => value3 )
