HomePHP Page 4 - Retrieving System Information With patSysinfo
Up and at 'Em - PHP
Linux file structure contains within it a special area called /proc. Now, some believe that there's black magic in that directory. For those who know better than to fear the /proc, there awaits much good magic, in the form of server info. Looking for a way to retrieve real-time server information and display it to users in your Web application? Today's your lucky day! Take a look at the patSysinfo PHP class, which lets you do that and a whole lot more.
The getUptime() method returns the time since the system's last reboot as an associative array with keys "days", "mins" and "hours". This can then easily be formatted into a readable string, as above. Here's the output:
Last reboot was 0 days, 1 hours and 43 minutes ago
Want to know a little bit more about the hardware and software running on the system? Take a look at the getKernelVersion() and getCpu() functions, which return the current kernel version and processor details respectively.
// include class include("patSysinfo.php");
// instantiate object $sys = new patSysinfo();
// get kernel version $kv = $sys->getKernelVersion();
// get processor information $cpuArray = $sys->getCpu();
// output values echo "Kernel $kv running on a $model at $speed MhZ ($cache cache, $mips bogomips)";
The getCpu() function, in particular, deserves closer attention. This function returns an array, each element of which is itself an associative array representing one of the processors in the CPU (most often, you will have a single-processor CPU and therefore only one element in this array). The associative array for each processor itself contains information on the processor name, clock speed, cache size and other relevant values.
Here's the output:
Kernel 2.4.20 running on a Pentium III (Katmai) at 451.03 MhZ (512 KB cache, 897.84 bogomips)
