php冒泡排序解决思路

php冒泡排序搜索了哈php冒泡排序，网上写的不知道第二层循环都是递减的，很不符合我的习惯，既然是冒泡肯定是从下往上啊，所以索性自己写了个分享哈！bubble_sort($ar);print_r($ar); function bubble_sort(&$ar){ $ar_count = count($ar); $temp = null; for($i= 0 ; $i { for($j = 0 ; $j { if($ar[$j] > $ar[$j+1]) { $temp = $ar[$j]; $ar[$j] = $ar[$j+1]; $ar[$j+1] = $temp; } } }}登录后复制 php 冒泡排序 ------解决方案--------------------$ar = array(24,1,3,2,8,3,5,6,10,13,27);bubble_sort($ar);function bubble_sort(&$ar){ $ar_count = count($ar); $temp = null; for($i= 0 ; $i { for($j = 0 ; $j { if($ar[$j] > $ar[$j+1]) { $temp = $ar[$j]; $ar[$j] = $ar[$j+1]; $ar[$j+1] = $temp; } }echo join(',', $ar), PHP_EOL; //观察这里的输出 }}登录后复制1,3,2,8,3,5,6,10,13,24,271,2,3,3,5,6,8,10,13,24,27 到这里排序已经结束1,2,3,3,5,6,8,10,13,24,27 从这里开始，以下都是无效劳动1,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,271,2,3,3,5,6,8,10,13,24,27大有优化的余地
