HomeBackend DevelopmentPHP TutorialHow to get real-time CPU memory usage in PHP in Windows

这次给大家带来php在windows内怎么取得cpu内存实时使用率,php在windows内取得cpu内存实时使用率的注意事项有哪些,下面就是实战案例,一起来看一下。

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
{
 /**
  * 判断指定路径下指定文件是否存在,如不存在则创建
  * @param string $fileName 文件名
  * @param string $content 文件内容
  * @return string 返回文件路径
  */
 private function getFilePath($fileName, $content)
 {
  $path = dirname(FILE) . "\\$fileName";
  if (!file_exists($path)) {
   file_put_contents($path, $content);
  }
  return $path;
 }
 /**
  * 获得cpu使用率vbs文件生成函数
  * @return string 返回vbs文件路径
  */
 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)"
  );
 }
 /**
  * 获得总内存及可用物理内存JSON vbs文件生成函数
  * @return string 返回vbs文件路径
  */
 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"
  );
 }
 /**
  * 获得CPU使用率
  * @return Number
  */
 public function getCpuUsage()
 {
  $path = $this->getCupUsageVbsPath();
  exec("cscript -nologo $path", $usage);
  return $usage[0];
 }
 /**
  * 获得内存使用率数组
  * @return array
  */
 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']}%";

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
