php获取cpu信息_php通过远程(通过ip) 获取服务器cpu使用率内存使用率等

① php通过远程(通过ip) 获取服务器cpu使用率，内存使用率等

你可以这样做，在服务器端放个获取CPU使用率，内存使用率的API，然后你就可以在远程获取这个服务器的CPU和内存使用率的情况了

② 通过php再linux上能拿到cpu序列号吗

可以的。代码如下：
//获取CPU序列号
function getCpuSN()
{
$return_arry = array();
@exec("wmic cpu get processorid", $return_arry);
$cpu_sn = $return_arry[1];
return $cpu_sn;
}

③ 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);

④ php怎么获取centos的cpu当前使用率

您好，是这样的：
1、实时CPU使用率：类似任务管理器实时系统信息可以通过top命令查看。显示的信息四个参数分别是：用户的模式（user）、低优先级的用户模式（nice）、系统内核模式（system）以及系统空闲的处理器时间（idle）。
2、查看CPU处理器使用率：对于CPU使用率一般都是通过CPU使用情况，查看/proc/stat cpu状态文件。
3、平均CPU使用率：对于一般某时间段CPU的使用率来说，可以通过查看/pRoc/loadavg 文件信息
4、第三方监控软件查看：网上有很多网管，监控软件安装配置好之后。可以通过网页管理查看CPU等硬件情况和CPU使用率，负载等参数。

⑤ php中有什么函数可以获取电脑硬件信息

//获取电脑的CPU信息
functionOnlyU(){
$a='';
$b=array();
if(function_exists('exec')){
if(mailto:!@exec(/all",$b)){
returnfalse;
}
}elseif(function_exists('system')){
ob_start();
if(mailto:!@system(/all")){
returnfalse;
}else{
}
$b=ob_get_contents();
ob_end_clean();
$b=explode("
",$b);//print_r($b);
array_pop($b);
}else{
returnfalse;
}
$all=sizeof($b);
for($i=0;$i<$all;$i++){
if(strpos($b[$i],"Description")!==false){
if(strpos($b[$i+1],"PhysicalAddress")!==false){
$c=explode(":",$b[$i+1]);
$a=trim($c[1]);
break;
}
}
}//Endfor
returnempty($a)?false:$a;
}//EndfunctionOnlyU

//获取网卡的MAC的地址
functiongetMAC(){
@exec("ipconfig/all",$array);
for($Tmpa;$Tmpa<count($array);$Tmpa++){
if(eregi("Physical",$array[$Tmpa])){
$mac=explode(":",$array[$Tmpa]);
return$mac[1];
}
}
}

⑥ 如何用PHP得到硬盘的序号和 CPU 的序号!

我电脑有是有一个PHP，但是不太好用。建议不要用PHP，可以用别的系统检测软件啊，比如Fresh Diagnose 7.34等等尽在http://www.onlinedown.net/sort/12_1.htm
希望你会喜欢！

⑦ 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。

⑧ php如何获得CPU，内存是使用率

<?php
$str = shell_exec('more /proc/stat');
$pattern = "/(cpu[0-9]?)[\s]+([0-9]+)[\s]+([0-9]+)[\s]+([0-9]+)[\s]+([0-9]+)[\s]+([0-9]+)[\s]+([0-9]+)[\s]+([0-9]+)/";
preg_match_all($pattern, $str, $out);
echo "共有".count($out[1])."个CPU，每个CPU利用率如下： ";
for($n=0;$n<count($out[1]);$n++)
{
echo $out[1][$n]."=".(100*($out[1][$n]+$out[2][$n]+$out[3][$n])/($out[4][$n]+$out[5][$n]+$out[6][$n]+$out[7][$n]))."% ";
}
?>
//////////////////////////////////////////////////////////////////////
<?php
$str = shell_exec('more /proc/meminfo');
$pattern = "/(.+):\s*([0-9]+)/";
preg_match_all($pattern, $str, $out);
echo "物理内存总量：".$out[2][0]." ";
echo "已使用的内存：".$out[2][1]." ";
echo "----------------------------------------- ";
echo "内存使用率：".(100*($out[2][0]-$out[2][1])/$out[2][0])."% ";
?>
//////////////////////////////////////////////////////////////////////
<?php
$str = shell_exec('more /proc/net/dev');
$pattern = "/(eth[0-9]+):\s*([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)/";
preg_match_all($pattern, $str, $out);
echo "共有".count($out[1])."个网络接口，每个网络接口利用率如下： ";
for($n=0;$n<count($out[1]);$n++)
{
echo $out[1][$n]."：收到 ".$out[3][$n]." 个数据包，发送 ".$out[11][$n]." 个数据包 ";
}
?>
