multidimensional array manipulation

[SeanHarding]

Hi have an array() in which I would like to manipulate certain elements:

 

Array
(
    [TESCO] => Array  (
            [Veg] => Array (
                    [Potatoe] => 12
                    [Cabbage] => 24
                    [Cucumber] => 56
                )
            [Meat] => Array (
                    [Chicken] => 54
                    [beef] => 89
                )
        )

    [ASDA] => Array (
            [Veg] => Array (
                    [Potatoe] => 12
                    [Cabbage] => 24
                    [Cucumber] => 56
                )
            [Meat] => Array (
                    [Chicken] => 23
                    [beef] => 90
                )
        )
)

 

How would I go about adding the price of my meat section together e.g. Chicken + Beef from ASDA = 113

 

Also how to add/remove elements from Meat/Veg?

Like adding Pork

 

Cheers

replace $array with what ever its real name is...

$totPrice = $array['ASDA']['Meat']['Chicken'] + $array['ASDA']['Meat']['Beef'];

 

That should work i think.

echo implode(" + ",array_keys($list['ASDA']['Meat'])).' = ' . array_sum($list['ASDA']['Meat']);

 

(assuming main array is called $list)

Assuming you can't be sure that the only meats will be 'chicken' and 'beef', and want the total of all the meats . . .

$meat_total = array_sum( $array['ASDA']['Meat'] );

[SeanHarding]

Worked perfectly.

 

Is there a way to automate it?

If I had numbered keys I'd use $i++ to run through them.

 

Basically I need a total under my Veg and Meat section. If I'm updating the prices individually I'd like code to update the total.

 

And how would I add Pork? lol

(you should read a bit about arrays)

 

$array['ASDA']['Meat']['Pork'] = 45;

[SeanHarding]

Have read quite allot about arrays but the multidimensional ones still confuse me.

 

How about removing Cabbage completely?

[freelance84]

$array[$supermarket][$foodArea][$food];

[WebStyles]

Multidemensional arrays are THE SAME as normal arrays except each element can be another array...

 

remove cabbage:

 

unset($array['ASDA']['Veg']['Cabbage']);

Thanks Guys,

 

I have been stuck on this for a while.

Reading your reply I can see that I set the item as a Key and all I need is the Value.

 

Thanks for your help.

 

I may be back

[SeanHarding]

ooooo how would I add Pork?

[WebStyles]

I've already answered that one.

[SeanHarding]

I love you,
