How can the issue of returning an integer instead of an array in PHP be fixed?

Issue: The problem of returning an integer instead of an array in PHP can be fixed by ensuring that the function always returns an array, even if it contains only one element. This can be achieved by using the array() function to create an array with the desired value.

// Fix for returning an array instead of an integer
function getArray() {
    return array(42);
}

// Call the function and store the result in a variable
$result = getArray();

// Output the result
print_r($result);
