//下面提供一三个针对函数来测试服务器的整数运算能力测试, 浮点运算能力测试和数据io能力测试哦。
代码如下 复制代码
    function test_int()
    {
        $timestart = gettimeofday();
        for($i = 0; $i         {
            $t = 1+1;
        }
        $timeend = gettimeofday();
        $time = ($timeend[usec]-$timestart[usec])/1000000+$timeend[sec]-$timestart[sec];
        $time = round($time, 3).秒;
        return $time;
    }
/*--------
    浮点运算能力测试
----------*/
代码如下 复制代码
  function test_float()
    {
        $t = pi();
        $timestart = gettimeofday();
        for($i = 0; $i         {
            sqrt($t);
        }
        $timeend = gettimeofday();
        $time = ($timeend[usec]-$timestart[usec])/1000000+$timeend[sec]-$timestart[sec];
        $time = round($time, 3).秒;
        return $time;
    }
/*-----
    数据io能力测试
-----*/
 代码如下 复制代码
    function test_io()
    {
        $fp = fopen(phpself, r);
        $timestart = gettimeofday();
        for($i = 0; $i         {
            fread($fp, 10240);
            rewind($fp);
        }
        $timeend = gettimeofday();
        fclose($fp);
        $time = ($timeend[usec]-$timestart[usec])/1000000+$timeend[sec]-$timestart[sec];
        $time = round($time, 3).秒;
        return($time);
    }

  很多公司都自己写了相关的服务器针探测试工具，我们为你提供的只是三种简的整型运算，浮点运算，与io数据输出压力测试。
