What are some common pitfalls when trying to access values in a multidimensional array in PHP?

One common pitfall when trying to access values in a multidimensional array in PHP is not properly specifying the index for each dimension. To access a value in a multidimensional array, you need to specify the index for each dimension, starting from the outermost dimension. Failure to do so can result in errors or incorrect data retrieval. 

// Example of accessing a value in a multidimensional array
$multiArray = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
];

// Correct way to access a value in a multidimensional array
echo $multiArray[1][2]; // Output: 6
