Php obtains real-time cpu memory usage in windows (recommended) and phpcpu

The CPU and memory usage of the backend Real-time Monitoring Server is very common. Although I have never done so, I did not expect it to take more than two hours to implement it before writing the code.

Although the keyword "php cup memory usage" is searched on the Internet, most of them are in the Linux environment. In windows, only the cmd statement is used for implementation, however, there are few actual and feasible code. I tried wmic and systeminfo a variety of unfamiliar cmd commands and did not find a feasible solution, finally, I found the implementation method obtained by using vbs through an answer that Baidu knows. It can be used directly in a windows environment with a slight improvement.

Class Code

Class SystemInfoWindows {/*** determines whether the specified file exists in the specified path, if not, create * @ param string $ fileName file name * @ param string $ content File content * @ return string returned file path */private function getFilePath ($ fileName, $ content) {$ path = dirname (_ FILE __). "\ $ fileName"; if (! File_exists ($ path) {file_put_contents ($ path, $ content);} return $ path ;} /*** obtain the cpu usage vbs file generation function * @ return string returns the vbs file 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) ");}/*** obtain the total memory and available physical memory JSON vbs file generation function * @ return string return vbs file path */private function getMemoryUsageVbsPath () {return $ this-> getFilePath ('memory _ usage. vbs ', "On Error Resume Next Set ob1_mi = GetObject (\" winmgmts :\\\\. \ root \ cimv2 \ ") Set colOS = ob1_mi. instancesOf (\ "Win32_OperatingSystem \") For Each objOS in colOS Wscript. echo (\ "{\" \ "TotalVisibleMemorySize \" \ ": \" & objOS. totalVisibleMemorySize & \ ", \" \ "FreePhysicalMemory \" \ ": \" & objOS. freePhysicalMemory & \ "} \") Next ");}/*** obtain CPU usage * @ return Number */public function getCpuUsage () {$ path = $ this-> getCupUsageVbsPath (); exec ("cscript-nologo $ path", $ usage); return $ usage [0];} /*** get the memory usage array * @ 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 ;}}

Call Method

$ Info = new SystemInfoWindows (); $ cpu = $ info-> getCpuUsage (); $ memory = $ info-> getMemoryUsage (); echo "current system CPU usage: {$ cpu }%, memory usage {$ memory ['usage']} % ";
