removing in arrays

[sekond]

suppose I have a 2dimensional array that contains keys i.e.

title=>Test, date=>2/27
Title=>other, date=>2/27
title=>test, date=>2/26
title=>test, date=>2/26
title=>test, date=>2/25
title=>other, date=>2/24

is there anyway to remove each section of 'test' that is older than the newest one, as well as 'other'?

Yes.

I figure using array_multisort with array_filter and unset, but i am not sure, I have been dabbling with it for sometime and having problems, anyone have any help they can give, code, or algorithms?

$array = array(
	array('title' => 'test', 'date' => '2/27'),
	array('title' => 'other', 'date' => '2/27'),
	array('title' => 'test', 'date' => '2/26'),
	array('title' => 'test', 'date' => '2/26'),
	array('title' => 'test', 'date' => '2/25'),
	array('title' => 'other', 'date' => '2/24')
);

foreach ($array as $key => $value)
{
	$timestamps[$value['title']][$key] = strtotime($value['date']);
}

foreach ($timestamps as $key => $value)
{
	asort($value);
	array_pop($value);
	$timestamps[$key] = $value;
}

foreach ($array as $key => $value)
{
	if (isset($timestamps[$value['title']][$key])) {unset($array[$key]);}
}

print_r($array);
