PHP obtains real-time CPU memory usage in Windows environment
这篇文章主要介绍了php在windows环境下获得 cpu 内存实时使用率的相关资料,非常不错,具有参考和学习PHP的价值,对PHP感兴趣的朋友可以参考下本篇文章
后台实时监控服务器的CUP与内存占用率的场景很常见,虽然没做过,但是着手写代码之前我真没想到会花2个多小时才最终实现。
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']}%";
总结

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

To install Laravel, follow these steps in sequence: Install Composer (for macOS/Linux and Windows) Install Laravel Installer Create a new project Start Service Access Application (URL: http://127.0.0.1:8000) Set up the database connection (if required)

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

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.

Laravel optimizes the web development process including: 1. Use the routing system to manage the URL structure; 2. Use the Blade template engine to simplify view development; 3. Handle time-consuming tasks through queues; 4. Use EloquentORM to simplify database operations; 5. Follow best practices to improve code quality and maintainability.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

Handling high DPI display in C can be achieved through the following steps: 1) Understand DPI and scaling, use the operating system API to obtain DPI information and adjust the graphics output; 2) Handle cross-platform compatibility, use cross-platform graphics libraries such as SDL or Qt; 3) Perform performance optimization, improve performance through cache, hardware acceleration, and dynamic adjustment of the details level; 4) Solve common problems, such as blurred text and interface elements are too small, and solve by correctly applying DPI scaling.
