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
