这款linux系统参数探测函数,可以计算出你当前机器的cpu是多少,内存多使用了多少，运行时间以及更新时间,实例代码如下:

    function sys_linux()

    {

        // CPU

        if (false === ($str = @file("/proc/cpuinfo"))) return false;

        $str = implode("", $str);

        @preg_match_all("/models+names{0,}:+s{0,}([ws)(.]+)[ ]+/", $str, $model);

        //@preg_match_all("/cpus+MHzs{0,}:+s{0,}([d.]+)[ ]+/", $str, $mhz);

        @preg_match_all("/caches+sizes{0,}:+s{0,}([d.]+s{0,}[A-Z]+[ ]+)/", $str, $cache);

        if (false !== is_array($model[1]))

            {

            $res['cpu']['num'] = sizeof($model[1]);

            for($i = 0; $i < $res['cpu']['num']; $i++)

            {

                $res['cpu']['detail'][] = "类型：".$model[1][$i]." 缓存：".$cache[1][$i];

            }

            if (false !== is_array($res['cpu']['detail'])) $res['cpu']['detail'] = implode("<br />", $res['cpu']['detail']);

            }





        // UPTIME

        if (false === ($str = @file("/proc/uptime"))) return false;

        $str = explode(" ", implode("", $str));

        $str = trim($str[0]);

        $min = $str / 60;

        $hours = $min / 60;

        $days = floor($hours / 24);

        $hours = floor($hours - ($days * 24));

        $min = floor($min - ($days * 60 * 24) - ($hours * 60));

        if ($days !== 0) $res['uptime'] = $days."天";

        if ($hours !== 0) $res['uptime'] .= $hours."小时";

        $res['uptime'] .= $min."分钟";



        // MEMORY

        if (false === ($str = @file("/proc/meminfo"))) return false;

        $str = implode("", $str);

        preg_match_all("/MemTotals{0,}:+s{0,}([d.]+).+?MemFrees{0,}:+s{0,}([d.]+).+?SwapTotals{0,}:+s{0,}([d.]+).+?SwapFrees{0,}:+s{0,}([d.]+)/s", $str, $buf);



        $res['memTotal'] = round($buf[1][0]/1024, 2);

        $res['memFree'] = round($buf[2][0]/1024, 2);

        $res['memUsed'] = ($res['memTotal']-$res['memFree']);

        $res['memPercent'] = (floatval($res['memTotal'])!=0)?round($res['memUsed']/$res['memTotal']*100,2):0;



        $res['swapTotal'] = round($buf[3][0]/1024, 2);

        $res['swapFree'] = round($buf[4][0]/1024, 2);

        $res['swapUsed'] = ($res['swapTotal']-$res['swapFree']);

        $res['swapPercent'] = (floatval($res['swapTotal'])!=0)?round($res['swapUsed']/$res['swapTotal']*100,2):0;

         //开源代码phpfensi.com

        // LOAD AVG

        if (false === ($str = @file("/proc/loadavg"))) return false;

        $str = explode(" ", implode("", $str));

        $str = array_chunk($str, 3);

        $res['loadAvg'] = implode(" ", $str[0]);



        return $res;

    }

//调用方法

sys_linux();
