Are there any best practices or common techniques for sorting multidimensional arrays efficiently in PHP?
When sorting multidimensional arrays in PHP, one common technique is to use the `array_multisort()` function. This function allows you to sort multiple arrays or multidimensional arrays based on one or more keys. By specifying the keys you want to sort by and the sorting order, you can efficiently sort multidimensional arrays in PHP.
// Sample multidimensional array
$users = array(
array('name' => 'John', 'age' => 30),
array('name' => 'Alice', 'age' => 25),
array('name' => 'Bob', 'age' => 35)
);
// Sort the array by 'age' key in ascending order
array_multisort(array_column($users, 'age'), SORT_ASC, $users);
// Output the sorted array
print_r($users);
