How can you reverse the values of the sub-arrays in a two-dimensional array in PHP?

To reverse the values of the sub-arrays in a two-dimensional array in PHP, you can iterate over each sub-array and use the `array_reverse` function to reverse the order of the elements within each sub-array. 

<?php
// Original two-dimensional array
$twoDArray = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
];

// Reverse the values of the sub-arrays
foreach ($twoDArray as &$subArray) {
    $subArray = array_reverse($subArray);
}

// Output the reversed two-dimensional array
print_r($twoDArray);
?>
