What are some potential pitfalls when deleting elements from a multidimensional array in PHP?

When deleting elements from a multidimensional array in PHP, one potential pitfall is that the indexes of the array may not be preserved, leading to unexpected behavior or errors in your code. To avoid this issue, you can use the unset() function to remove the element from the array without affecting the indexes of other elements. 

// Example of deleting an element from a multidimensional array in PHP
$multiArray = array(
    array("apple", "orange", "banana"),
    array("carrot", "lettuce", "tomato"),
    array("dog", "cat", "bird")
);

// Remove the element "lettuce" from the second sub-array
unset($multiArray[1][1]);

// Output the updated multidimensional array
print_r($multiArray);
