What are the limitations of using multi-dimensional arrays in PHP compared to other programming languages?

One limitation of using multi-dimensional arrays in PHP compared to other programming languages is that PHP does not support true multi-dimensional arrays, but rather arrays of arrays. This can lead to confusion and make it more challenging to work with multi-dimensional data structures. One way to work around this limitation is to use nested arrays to simulate multi-dimensional arrays. 

// Simulating a multi-dimensional array with nested arrays
$multiDimArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

// Accessing elements in the simulated multi-dimensional array
echo $multiDimArray[1][2]; // Output: 6
