?>

此PHP类，根据操作系统来进行判断。

调用<?php echo '['.$sys_info['cpu']['num_text'].'] '.$sys_info['cpu']['model'] ?>

参考如下：

获取服务器性能CPU、内存、硬盘等使用率 get_used_status.php

<?php

include("conn.php")

$obj_MyConnect = new MyConnect()

$obj_MyConnect ->connect(DB_SERVER,DB_USER,DB_PWD,DB_NMAE)

function get_used_status(){

$fp = popen('top -b -n 2 | grep -E "^(Cpu|Mem|Tasks)"',"r")//获取某一时刻系统cpu和内存使用情况

$rs = ""

while(!feof($fp)){

$rs .= fread($fp,1024)

}

pclose($fp)

$sys_info = explode("\n",$rs)

$tast_info = explode(",",$sys_info[3])//进程 数组

$cpu_info = explode(",",$sys_info[4]) //CPU占有量 数组

$mem_info = explode(",",$sys_info[5])//内存占有量 数组

//正在运行的进程数

$tast_running = trim(trim($tast_info[1],'running'))

//CPU占有量

$cpu_usage = trim(trim($cpu_info[0],'Cpu(s): '),'%us') //百分比

//内存占有量

$mem_total = trim(trim($mem_info[0],'Mem: '),'k total')

$mem_used = trim($mem_info[1],'k used')

$mem_usage = round(100*intval($mem_used)/intval($mem_total),2) //百分比

$fp = popen('df -lh | grep -E "^(/)"',"r")

$rs = fread($fp,1024)

pclose($fp)

$rs = preg_replace("/\s{2,}/",' ',$rs) //把多个空格换成 “_”

$hd = explode(" ",$rs)

$hd_avail = trim($hd[3],'G')//磁盘可用空间大小 单位G

$hd_usage = trim($hd[4],'%')//挂载点 百分比

//print_r($hd)

//检测时间

$fp = popen("date +"%Y-%m-%d %H:%M"","r")

$rs = fread($fp,1024)

pclose($fp)

$detection_time = trim($rs)

在cmd下 用批处理语句获取windows的CPU 内存使用情况的语句，找下。

然后php有执行 OS 原生脚本的函数，跟你在CMD下执行一样。

执行完，获取返回的信息即可。
