How can PHP developers handle dynamically changing keys in multidimensional arrays for efficient data manipulation?

When dealing with dynamically changing keys in multidimensional arrays, PHP developers can use functions like array_keys() and array_values() to retrieve and manipulate the keys and values efficiently. By dynamically accessing and updating array elements based on their keys, developers can ensure flexibility and adaptability in their data manipulation processes. 

// Example of handling dynamically changing keys in a multidimensional array
$myArray = [
    'first' => [
        'name' => 'John',
        'age' => 30
    ],
    'second' => [
        'name' => 'Jane',
        'age' => 25
    ]
];

// Get all keys in the first level of the array
$keys = array_keys($myArray);

foreach($keys as $key) {
    // Access and manipulate data based on keys
    echo "Key: " . $key . "\n";
    echo "Name: " . $myArray[$key]['name'] . "\n";
    echo "Age: " . $myArray[$key]['age'] . "\n";
}
