How can one access a specific element within a nested array in PHP?

To access a specific element within a nested array in PHP, you need to specify the index of each nested array level. For example, if you have a nested array called $nestedArray and you want to access an element within the second level array, you would use $nestedArray[index1][index2]. This allows you to drill down into the nested structure and access the desired element. 

$nestedArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

$element = $nestedArray[1][2]; // Accessing the element '6' in the nested array
echo $element; // Output: 6
