How can you access specific data within a multidimensional array in PHP?

To access specific data within a multidimensional array in PHP, you need to specify the index for each dimension of the array. For example, if you have a multidimensional array $arr and you want to access the element at index [1][2], you would use $arr[1][2]. 

// Sample multidimensional array
$arr = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

// Accessing specific data within the multidimensional array
echo $arr[1][2]; // Output: 6
