How do I find max values in a multidimensional array? - php

Question

I Have an array which looks like this:
Array
(
[0] => Array
(
[0] => Array
(
[product] => 2003
[date] => 2010-09-15 13:27:35
[status] => 3
)
[1] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 1
)
[2] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 6
)
)
[1] => Array
(
[0] => Array
(
[product] => 2003
[date] => 2010-09-12 13:27:35
[status] => 1
)
[1] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 4
)
[2] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 1
)
)
[2] => Array
(
[0] =>
[1] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 1
)
[2] => Array
(
[product] => 2004
[date] => 2010-09-18 13:27:35
[status] => 1
)
)
I want to "collapse" each second dimension array and obtain the max DATE value and the max status value.So the first index would return 2010-09-18 13:27:35 and '6' etc.
The problem is further complicated by the empty array in the last index. I would like to use this empty array and report it as the MAX date and status.
Thank in advance!

Thanks for looking everybody. I figured it out.
$date=array();
$status=array();
$availability=array();
foreach($set as $key => $value)
{
foreach($value as $value2)
{
if(isset($value2[1]))
{
$date[$key][]=$value2[1];
$status[$key][]=$value2[2];
}
else
{
$date[$key][]='2022-09-18 13:27:35';
$status[$key][]='0';
}
}
$availability[$key]=array(max($date[$key]),min($status[$key]));
}
