php中的冒泡排序,选择排序,插入排序
??//冒泡排序
??function bubbleSort(&$arr){
????
????$temp=0;
????
????//加入第i个数最大
????for($i=0;$i
??????for($j=0;$j

??????????$arr[$j+1]=$temp;
????????}
??????}

??//选择排序
??function selectSort(&$arr){
????
????$temp=0;
????

??????
??????//最后交换

??//插入排序法
??function insertSort(&$arr){
