Use PHPSysInfo library

phpSysInfo is a open source PHP script that displays information about the host being accessed. It will displays things like:

  • Uptime
  • CPU
  • Memory
  • SCSI, IDE, PCI
  • Ethernet
  • Floppy
  • Video Information

It directly parsed parses /proc and does not use exec.

Another way is to use Linfo. It is a very fast cross-platform php script that describes the host server in extreme detail, giving information such as ram usage, disk space, raid arrays, hardware, network cards, kernel, os, samba/cups/truecrypt status, temps, disks, and much more.

and it gets all of this information without the exec ?? – Ronan Dejhero Jan 16 '11 at 14:12
@Ronan - it reads directly from /proc, provided open_basedir() is not in effect. So, you should fall back to exec() if that restriction is in place. – Tim Post♦ Jan 16 '11 at 14:13
i mean will it work on a shared hosting or does it need some functions enabled (like exec) , my script will be installed by many customers on many hosting plans/dedicated servers and stuff , i need something to work on everything , or with functions that could be enabled ... – Ronan Dejhero Jan 16 '11 at 14:14
@Ronan: Yes, it does not use exec. Try installing that script on your web-server to quickly check. It works on my shared server. – shamittomar Jan 16 '11 at 14:14
What if PHPSysInfo tells me that file_exists(/proc/net/dev) does not exist on my machine? – what Apr 5 at 9:24
