What is the best practice for accessing individual elements within a multidimensional array in PHP?

When accessing individual elements within a multidimensional array in PHP, it is best practice to use nested square brackets to specify the indices of each dimension. This allows you to traverse through the array and access the desired element accurately. 

// Example of accessing individual elements within a multidimensional array
$multiDimArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

// Accessing the element at row 1, column 2
$element = $multiDimArray[1][2];
echo $element; // Output: 6
