很多站长朋友们都不太清楚php查询cpu信息，今天小编就来给大家整理php查询cpu信息，希望对各位有所帮助，具体内容如下：

//根据操作系统取得CPU相关信息
switch(PHP_OS) {

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']; ?>
PHP如何在windows下获取计算机的cpu和内存在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。
Windows下 PHP怎么获取CPU和内存使用率。。。。急参考如下：
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);
PHP能否获取客户端唯一标识（cpu序列号，mac地址等）权限足够的情况下，可以输出cpu信息php调用：$a = exec('cat /proc/stat'); php有个执行方式是用``包裹字符串，同样可以在系统上直接执行 同样需要足够的权限。
