I don't think PHP is the best tool for this. You'll need exec() to run top (assuming your host runs something with X at the end), and it's disabled on most servers.

For Windows, just use Powershell and you can get pretty much any report you want.

For Linux, Perl or Python with some kind of graph plugin.

Thank you for your replay..

i just need to know on my local system the % of memory used by the top 6 process..
do u think this will give correct answer.

ps -eo pmem,vsize,pid | sort -nr | head -6
Dan CraciunIT ConsultantCommented:
That will give you the pid for the top 6 processes, sorted first by %mem usage (which will usually be under 1%, on systems with lots of RAM) and then by virtual size.

 ps axo pmem,vsize,pid | sort -r | head -7
