 <p>Your best bet is probably to use <a href="http://www.php.net/manual/en/function.shell-exec.php" rel="nofollow">shell_exec</a> to cat some of the data from the various /proc/* files that are commonly used on Linux/Unix systems, the key ones probably being:</p> <ul> <li>/proc/cpuinfo</li> <li>/proc/meminfo</li> </ul> <p>For example:</p> <pre><code>echo shell_exec('cat /proc/cpuinfo/'); </code></pre>
