Mounting Up - 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.

TOOLS YOU CAN USE

Finally, you can obtain information on mounted file system with the getMounts() method, which returns an array containing detailed information from both the "df" command and "/proc/mounts". Take a look:

<?php // include class include("patSysinfo.php"); // instantiate object $sys = new patSysinfo(); // get mounted file systems $mounts = $sys->getMount(); // output mount information print_r($mounts); die; ? >

Here's what the output of this script might look like:

Array
(
    [0] => Array
        (
            [disk] => /dev/hda3
            [size] => 4.73 GByte
            [used] => 923.00 MByte
            [free] => 3.59 GByte
            [percent] => 21
            [mount] => /
            [type] => ext2
        )
    [1] => Array
        (
            [disk] => /dev/hda2
            [size] => 4.89 GByte
            [used] => 346.95 MByte
            [free] => 4.55 GByte
            [percent] => 7
            [mount] => /mnt/dos
            [type] => vfat
        )
    [2] => Array
        (
            [disk] => /dev/hda4
            [size] => 15.64 MByte
            [used] => 1.79 MByte
            [free] => 13.85 MByte
            [percent] => 12
            [mount] => /mnt/scamp
            [type] => msdos
        )
)

Of course, this isn't very useful by itself - what you really need to do is format it into a tabular representation, like this:

<html> <head> </head> <body> <table border="1" cellspacing="0" cellpadding="5"> <tr> <td>Disk</td> <td>Mount point</td> <td>Type</td> <td>Size</td> <td>Used space</td> <td>Free space</td> <td>Used space %</td> </tr> <?php // include class include("patSysinfo.php"); // instantiate object $sys = new patSysinfo(); // get mounted file systems $mounts = $sys->getMount(); // output mount information foreach($mounts as $m) { echo "<tr>"; echo "<td>" . $m['disk'] . "</td>"; echo "<td>" . $m['mount'] . "</td>"; echo "<td>" . $m['type'] . "</td>"; echo "<td>" . $m['size'] . "</td>"; echo "<td>" . $m['used'] . "</td>"; echo "<td>" . $m['free'] . "</td>"; echo "<td>" . $m['percent'] . " %</td>"; echo "</tr>"; } ? > </body> </html>
