网上虽然搜 PHP CUP 内存 使用率 这一类关键字出来的文章一大把,但大都是在Linux环境下,windows下只有提出靠cmd语句实现的观点,但少有实际直接可行的代码,辗转试了一遍 wmic , systeminfo 各种并不熟稔的cmd命令,并没有找到可行的方案,最终通过百度知道 的一篇答案找到利用vbs获取的实现方式,稍加改善,可以在windows环境下直接使用。
类代码
class SystemInfoWindows
{
private function getFilePath($fileName, $content)
{
$path = dirname(__FILE__) . "\\$fileName";
if (!file_exists($path)) {
file_put_contents($path, $content);
}
return $path;
}
private function getCupUsageVbsPath()
{
return $this->getFilePath(
'cpu_usage.vbs',
"On Error Resume Next
Set objProc = GetObject(\"winmgmts:\\\\.\\root\cimv2:win32_processor='cpu0'\")
Wscript.Echo(objProc.LoadPercentage)"
);
}
private function getMemoryUsageVbsPath()
{
return $this->getFilePath(
'memory_usage.vbs',
"On Error Resume Next
Set objWMI = GetObject(\"winmgmts:\\\\.\\root\cimv2\")
Set colOS = objWMI.InstancesOf(\"Win32_OperatingSystem\")
For Each objOS in colOS
Wscript.Echo(\"{\"\"TotalVisibleMemorySize\"\":\" & objOS.TotalVisibleMemorySize & \",\"\"FreePhysicalMemory\"\":\" & objOS.FreePhysicalMemory & \"}\")
Next"
);
}
public function getCpuUsage()
{
$path = $this->getCupUsageVbsPath();
exec("cscript -nologo $path", $usage);
return $usage[0];
}
public function getMemoryUsage()
{
$path = $this->getMemoryUsageVbsPath();
exec("cscript -nologo $path", $usage);
$memory = json_decode($usage[0], true);
$memory['usage'] = Round((($memory['TotalVisibleMemorySize'] - $memory['FreePhysicalMemory']) / $memory['TotalVisibleMemorySize']) * 100);
return $memory;
}
}调用方式
$info = new SystemInfoWindows();
$cpu = $info->getCpuUsage();
$memory = $info->getMemoryUsage();
echo "当前系统CPU使用率:{$cpu}%,内存使用率{$memory['usage']}%";相关推荐:
