Max Value of multidimensional array - php

Question

I have this Array
Array
(
[2014-08-14] => Array
(
[18:00:00] => Array
(
[6] => Array
(
[price] => 15.36
[avail_clean] => 5
[avail_noclean] => 6
)
[7] => Array
(
[price] => 17.35
[avail_clean] => 2
[avail_noclean] => 3
)
)
[19:00:00] => Array
(
[6] => Array
(
[price] => 15.36
[avail_clean] => 5
[avail_noclean] => 6
)
[7] => Array
(
[price] => 17.35
[avail_clean] => 2
[avail_noclean] => 3
)
)
)
)
How can I get the following for 6 & 7 seperately:
- Sum of price
- max of avail_clean
- max of avail_noclean
I got that far for the price:
foreach ($bookable as $date=>$key) {
foreach ($key as $time=>$key2) {
foreach($key2 as $room=>$key3){
foreach($key3 as $price=>$key4){
if($price == "price"){
if(isset($sumRoom[$room]['total'])){
$sumRoom[$room]['total'] += $key4;
}else{
$sumRoom[$room]['total'] = $key4;
}
}
}
}
}
}
Gives me this
Array(
[6] => Array
(
[total] => 30,72
)
[7] => Array
(
[total] => 34,7
)
)
But what about the max(), where should I put that?

Answer 1

foreach ($bookable as $date=>$times) {
foreach ($times as $time=>$rooms) {
foreach($rooms as $room=>$options){ $sumRoom[$room]['total'] = 0;
foreach($options as $option=>$value){
if($option == "price"){
$sumRoom[$room]['total'] += $value;
}
if($option == "avail_clean"){
$avail_clean[$room][] = $value;
}
if($option == "avail_noclean"){
$avail_noclean[$room][] = $value;
}
}
$sumRoom[$room]['avail_clean_max'] = max($avail_clean[$room]);
$sumRoom[$room]['avail_noclean'] = max($avail_noclean[$room]);
}
}
}
I've edited my answer.. I've merged all in one array i.e. $sumRoom
