What is the difference between manually providing arguments to array_multisort and generating them dynamically in PHP?

When manually providing arguments to array_multisort in PHP, you need to explicitly specify the arrays and sorting orders for each column. On the other hand, generating arguments dynamically allows for a more flexible approach where you can dynamically build the arguments based on the data or conditions. 

// Manually providing arguments to array_multisort
$array = [['name' => 'John', 'age' => 30], ['name' => 'Alice', 'age' => 25]];
array_multisort(array_column($array, 'name'), SORT_ASC, array_column($array, 'age'), SORT_DESC);

// Generating arguments dynamically for array_multisort
$array = [['name' => 'John', 'age' => 30], ['name' => 'Alice', 'age' => 25]];
$sortArgs = [];
foreach ($array[0] as $key => $value) {
    $sortArgs[] = array_column($array, $key);
    $sortArgs[] = SORT_ASC;
}
array_multisort(...$sortArgs);
