PHP排序算法(插入,选择,交换,冒泡,快速)

<?php //冒泡排序function BubbleSort($arr) {    // 获得数组总长度    $num = count($arr);    // 正向遍历数组    for ($i = 1; $i < $num; $i++) {        // 反向遍历        for ($j = $num - 1; $j >= $i ; $j--) {            // 相邻两个数比较            if ($arr[$j] = 0) && ($iTemp  1) {        $left = QuickSort($left);    }    // 排序后的数组    $new_arr = $left;    // 将当前数组第一个放到最后    $new_arr[] = $arr[0];    // 如果又索引有值 则对右索引排序    if ($r > 1) {        $right = QuickSort($right);    }    // 根据右索引的长度再次增加数据    for($i = 0;$i
