When working with multidimensional arrays in PHP, what strategies can be implemented to ensure correct sorting and iteration through the data?

When working with multidimensional arrays in PHP, it is important to use the correct sorting functions and iteration methods to ensure data is processed accurately. One strategy is to use nested loops to iterate through the array and access the inner arrays. Additionally, using functions like `array_multisort()` can help sort multidimensional arrays based on specific keys or values. 

// Example of sorting a multidimensional array by a specific key
$multiArray = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Alice', 'age' => 35]
];

// Sort the array by 'age' key in ascending order
array_multisort(array_column($multiArray, 'age'), SORT_ASC, $multiArray);

// Iterate through the sorted array
foreach ($multiArray as $person) {
    echo $person['name'] . ' - ' . $person['age'] . '<br>';
}
