if($arr[$i]==$findValue){ echo "我要查找数的下标是:".$i.""; $flag=true; //break; } } if(!$flag){ echo "找不到你想要查找的数:".$findValue; } } $myarr=array(12,34,34,5940); search($myarr,4); ?> ❷二分查找 <?php function binarySearch(&$arr,$findValue,$leftIndex...
1.2.2 select 的 selectOrFail、toArray 操作 find 有 finOrFail 操作,那么同样的 select 也有此操作,当查询数据集时若返回为空想要抛出异常,那么就使用 selectOrFail,此时代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 $res=Db::table('student')->where('height',170)->selectOrFail(); ...
