php獲取cpu信息_php通過遠程(通過ip) 獲取伺服器cpu使用率內存使用率等

① php通過遠程(通過ip) 獲取伺服器cpu使用率，內存使用率等

你可以這樣做，在伺服器端放個獲取CPU使用率，內存使用率的API，然後你就可以在遠程獲取這個伺服器的CPU和內存使用率的情況了

② 通過php再linux上能拿到cpu序列號嗎

可以的。代碼如下：
//獲取CPU序列號
function getCpuSN()
{
$return_arry = array();
@exec("wmic cpu get processorid", $return_arry);
$cpu_sn = $return_arry[1];
return $cpu_sn;
}
本代碼來自一棵隨風倒的小小草的CSDN 博客，全文地址請點擊：https://blog.csdn.net/hnllc2012/article/details/48733887?utm_source=

③ Windows下 PHP怎麼獲取CPU和內存使用率。。。。急

參考如下：
獲取伺服器性能CPU、內存、硬碟等使用率 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");//獲取某一時刻系統cpu和內存使用情況
$rs = "";
while(!feof($fp)){
$rs .= fread($fp,1024);
}
pclose($fp);
$sys_info = explode("\n",$rs);
$tast_info = explode(",",$sys_info[3]);//進程數組
$cpu_info = explode(",",$sys_info[4]); //CPU佔有量數組
$mem_info = explode(",",$sys_info[5]); //內存佔有量數組
//正在運行的進程數
$tast_running = trim(trim($tast_info[1],'running'));
//CPU佔有量
$cpu_usage = trim(trim($cpu_info[0],'Cpu(s): '),'%us'); //百分比
//內存佔有量
$mem_total = trim(trim($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); //把多個空格換成「_」
$hd = explode(" ",$rs);
$hd_avail = trim($hd[3],'G'); //磁碟可用空間大小單位G
$hd_usage = trim($hd[4],'%'); //掛載點百分比
//print_r($hd);

//檢測時間
$fp = popen("date +"%Y-%m-%d %H:%M"","r");
$rs = fread($fp,1024);
pclose($fp);
$detection_time = trim($rs);

④ php怎麼獲取centos的cpu當前使用率

您好，是這樣的：
1、實時CPU使用率：類似任務管理器實時系統信息可以通過top命令查看。顯示的信息四個參數分別是：用戶的模式（user）、低優先順序的用戶模式（nice）、系統內核模式（system）以及系統空閑的處理器時間（idle）。
2、查看CPU處理器使用率：對於CPU使用率一般都是通過CPU使用情況，查看/proc/stat cpu狀態文件。
3、平均CPU使用率：對於一般某時間段CPU的使用率來說，可以通過查看/pRoc/loadavg 文件信息
4、第三方監控軟體查看：網上有很多網管，監控軟體安裝配置好之後。可以通過網頁管理查看CPU等硬體情況和CPU使用率，負載等參數。

⑤ php中有什麼函數可以獲取電腦硬體信息

//獲取電腦的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

//獲取網卡的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得到硬碟的序號和 CPU 的序號!

我電腦有是有一個PHP，但是不太好用。建議不要用PHP，可以用別的系統檢測軟體啊，比如Fresh Diagnose 7.34等等盡在http://www.onlinedown.net/sort/12_1.htm
希望你會喜歡！

⑦ PHP能否獲取客戶端唯一標識（cpu序列號，mac地址等）

許可權足夠的情況下，可以輸出cpu信息php調用：$a = exec('cat /proc/stat'); php有個執行方式是用``包裹字元串，同樣可以在系統上直接執行同樣需要足夠的許可權。

⑧ php如何獲得CPU，內存是使用率

<?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])."個CPU，每個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, $out);
echo "物理內存總量：".$out[2][0]." ";
echo "已使用的內存：".$out[2][1]." ";
echo "----------------------------------------- ";
echo "內存使用率：".(100*($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])."個網路介面，每個網路介面利用率如下： ";
for($n=0;$n<count($out[1]);$n++)
{
echo $out[1][$n]."：收到 ".$out[3][$n]." 個數據包，發送 ".$out[11][$n]." 個數據包 ";
}
?>
