sort的各种排序~

上例结果如下:

asort排序
Array ( [0] => 5 [2] => 10 [3] => 29 [1] => 87 )
sort排序
Array ( [0] => 5 [1] => 10 [2] => 29 [3] => 87 )
ksort排序
Array ( [1] => 87 [2] => 10 [3] => 29 [4] => 5 )
rsort排序
Array ( [0] => 87 [1] => 29 [2] => 10 [3] => 5 )
arsort排序
Array ( [1] => 87 [3] => 29 [2] => 10 [0] => 5 )
krsort排序
Array ( [4] => 5 [3] => 29 [2] => 10 [1] => 87 )
