如何在Windows上以PHP的形式获取每个CPU Core的负载？

Question

Is there a way to do so? I tried using WMI, and the Win32_PerfRawData_PerfOS_Processor class, i end up having the PercentProcessorTime and Timestamp_PerfTime which would require to sleep a while to calculate the percentage, but thats not what i need, i need something that does not require PHP to wait a couple second, it should print out the load almost instantly

Answer 1

One way would be to have another program that continuously checks and logs the processor load somewhere where PHP would be able to read the values directly. There would probably be a slight delay in the logging but nothing like a couple of seconds.

You could probably do that in a separate PHP script. Just make sure you sleep() for a short while between the checks, otherwise the processor reading script would push the processor to maximum load immediately.
