[!--quoteo(post=368105:date=Apr 24 2006, 08:28 PM:name=SemiApocalyptic)--][div class=\'quotetop\']QUOTE(SemiApocalyptic @ Apr 24 2006, 08:28 PM) [snapback]368105[/snapback][/div][div class=\'quotemain\'][!--quotec--] Just tested this on my WinXP Pro box and works ok - Bare in mind I have a processor with hyperthreading enabled so the output index might be different for the available memory compared to the machine you may run it on - If it is incorrect, run print_r($output) to get the correct index. [code]<?php exec("systeminfo",$output) echo $output[26]; ?>[/code] Hope this helps. NOTE: I have left the semi-colon off of the end of the exec() line as it appears I can't post with it there - Looks like a forum bug... [/quote] Many thanks to both of you for replying - the "systeminfo" seems a great way to go.
