目前,我按字符串长度排序数组.但是,当字符串长度相等时,我如何按值排序？

例如,我目前的代码:

$array = array("A","BC","AA","C","BB", "B");

function lensort($a,$b){
    return strlen($a)-strlen($b);
}

usort($array,'lensort');

print_r($array);

输出:

Array
(
    [0] => C
    [1] => A
    [2] => B
    [3] => BB
    [4] => AA
    [5] => BC
)

但是,我希望它按以下方式排序:

Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => AA
    [4] => BB
    [5] => BC
)
