Unique array values in foreach

[m|sf|t]

All,
I have a snippet of code below. In my foreach, I would like to process only
1 item per hdd value, in the case below, the echo $tib['hdd'] . "\n"; would
only display 1 and 2, not 1,1,1,1,2,2,2,2 . It doesn't matter which one
shows, because I only want the unique value for hdd.

$tibs = array(
"tib1" => array("drive" => "C", "progress" => "on", "hdd" => "1",
"partition" => "1", "compressio n" => "3", "backup" => "K:\\"),
"tib2" => array("drive" => "D", "progress" => "on", "hdd" => "1",
"partition" => "2", "compressio n" => "3", "backup" => "K:\\"),
"tib3" => array("drive" => "E", "progress" => "on", "hdd" => "1",
"partition" => "3", "compressio n" => "3", "backup" => "K:\\"),
"tib4" => array("drive" => "F", "progress" => "on", "hdd" => "1",
"partition" => "4", "compressio n" => "3", "backup" => "K:\\"),
"tib5" => array("drive" => "G", "progress" => "on", "hdd" => "2",
"partition" => "1", "compressio n" => "3", "backup" => "L:\\"),
"tib6" => array("drive" => "H", "progress" => "on", "hdd" => "2",
"partition" => "2", "compressio n" => "3", "backup" => "L:\\"),
"tib7" => array("drive" => "I", "progress" => "on", "hdd" => "2",
"partition" => "3", "compressio n" => "3", "backup" => "L:\\"),
"tib8" => array("drive" => "J", "progress" => "on", "hdd" => "2",
"partition" => "4", "compressio n" => "3", "backup" => "L:\\"),
);

foreach($tibs as $tib) {
echo $tib['hdd'] . "\n";
}

Thanks for any help.

$_tibs = array();
foreach($tibs as $tib)
{
if ( !in_array($tib['hdd'], $_tibs) )
{
echo $tib['hdd'] . "\n";
$_tibs[] = $tib['hdd'];
}
}
