php脚本为每个进程获取cpu利用率？

Question

How do I get the CPU usage for each process that is currently running on the local system or server using PHP.

How can I use the Command Prompt command tasklist from within PHP and fetch process names and memory information.

Here is the example :

Name of Processor     Memory usage
Edit plus              6.1 MB
Google Chrome           20 MB
Command Prompt           5 MB
Tomcat                 2.1 MB

Answer 1

Seeing as you've changed the specification for the answer and I don't wish to remove or butcher my other answer which may be an acceptable solution for others.

If you MUST use the Command Prompt command tasklist to retrieve the process data then you can then call this Application using exec() from PHP.

<?php
exec('tasklist.exe', $outputLines);

foreach($line in $outputLines)
{
    //Extract information from String...
}
?>

You will then need to use String manipulation to extract the information you want. Regex might be a good choice.
