在PHP中按字母顺序排列数组，然后按数字排列吗？

$myArray = array("apple", "banana", "cherry", "2", "1", "3");
sort($myArray);
print_r($myArray);

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => apple
    [4] => banana
    [5] => cherry
)

$myArray = array("apple", "banana", "cherry", "2", "1", "3");
natsort($myArray);
print_r($myArray);

Array
(
    [4] => 1
    [3] => 2
    [5] => 3
    [0] => apple
    [1] => banana
    [2] => cherry
)
