Are there any specific PHP functions or techniques that can help in dynamically generating and passing arguments to array_multisort for sorting multidimensional arrays efficiently?

When sorting multidimensional arrays using array_multisort in PHP, dynamically generating and passing arguments can be challenging as the number of dimensions and keys can vary. One efficient way to handle this is by using the call_user_func_array function to dynamically pass arguments to array_multisort based on the keys of the multidimensional array. 

// Sample multidimensional array
$data = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Alice', 'age' => 35],
];

// Define the keys to sort by
$keys = ['name', 'age'];

// Generate the arguments for array_multisort
$args = [];
foreach ($keys as $key) {
    $args[] = array_column($data, $key);
    $args[] = SORT_ASC; // Sorting order
}

// Dynamically pass arguments to array_multisort using call_user_func_array
$args[] = &$data;
call_user_func_array('array_multisort', $args);

// Output the sorted array
print_r($data);
