How can proper code formatting help in improving the readability of multidimensional arrays in PHP?

Proper code formatting can help improve the readability of multidimensional arrays in PHP by making the structure of the array more visually clear. This includes using indentation to show the hierarchy of nested arrays, aligning array keys and values for easy comparison, and using consistent spacing and line breaks to separate different levels of the array. 

$multiArray = [
    'first_level' => [
        'second_level' => [
            'key1' => 'value1',
            'key2' => 'value2',
        ],
        'another_second_level' => [
            'key3' => 'value3',
            'key4' => 'value4',
        ],
    ],
    'another_first_level' => [
        'key5' => 'value5',
    ],
];
