Here is a snippet from my dhcp web page found on my site below... Not
exactly what you want, but could help you start...
// read in the dhcp_map.ini file to map MAC addresses to images
$mapFile = "./dhcp_map.ini";
if( $fp = @fopen($mapFile, "r") )
{
while( $line = fgets($fp, 1024) )
if ($line{0} != "#") $tempMap .= $line; // strip
out # comments
} else echo "ERROR: Can't read ".$mapFile."<BR>";
fclose ($fp);
$map = explode("\n", $tempMap);
//print_r($map);
for($i = 0; $i < count($map); $i++)
{
list($mac, $image, $name) = preg_split("/\s/",$map[$i], -1,
PREG_SPLIT_NO_EMPTY);
//if ( array_key_exists($mac, $machine))
$machine[$mac]->setImage($image);
if ( isset($machine[$mac]) )
$machine[$mac]->setImage($image);
if ( isset($machine[$mac]) && $name != "" &&
$machine[$mac]->getName() == "") $machine[$mac]->name = $name;
}
unset($tempMap);
unset($map);
