一道关于microtime()的题目
php获取时间的函数
$gtc_end_time = microtime(true);

 
从下面这种数列中(1000个吧),
19493845809,24359390850934,3435345,4345345,5345345,6345345,73453453 …… 
判断某个数:234343345 是否存在这里面,
计算一下看需要多少时间

------解决方案--------------------

PHP code
$k = 10000;$ar = range(1, $k);$t =  microtime(true);if(in_array($k, $ar))  echo microtime(true) - $t;<div class="clear">
                 
              
              
        
            </div>
Copy after login
