按键PHP CodeIgniter的数组

Question

I have the following response from my PHP code.

Array
(
[customer] => 402
[carat] => Array
    (
        [0] => 6
        [1] => 5
    )

[units] => Array
    (
        [0] => grams
        [1] => dwt
        [2] => dwt
    )

[weight] => Array
    (
        [0] => 5
        [1] => 3
        [2] => 6
    )

[our_payout] => Array
    (
        [0] => 15
        [1] => 9
        [2] => 60
    )

[sale_payout] => Array
    (
        [0] => 18
        [1] => 12
        [2] => 180
    )

[hidden_carat] => Array
    (
        [0] => 6
        [1] => 5
        [2] =>
    )

[hidden_unit] => Array
    (
        [0] => 1
        [1] => 2
        [2] => 2
    )

[carat_scale_price] => Array
    (
        [0] =>
        [1] =>
        [2] =>
    )

[sales_id] => Array
    (
        [0] =>
        [1] =>
        [2] =>
    )

[currency_rate_id] => Array
    (
        [0] =>
        [1] =>
        [2] =>
    )

[gold_price_id] => Array
    (
        [0] =>
        [1] =>
        [2] =>
    )

[taget_percentage] =>
[reference] => 0
[notes] =>
[unit] => 0
[customer_id] => 402
[total_items] => 2
[submit] =>
)

And I want to join for example [0] => grams with [0] => 5 [0] => 16 and so on. How can I do that?

I'm with Steve, I'm not really sure what you're asking for. It looks like you want to transpose that matrix but only for some of the keys? Here's something that might do what you're looking for, assuming that your original array above is in the variable $arr:

$lineItems = array();
$i = 0;
$allLineItemsHaveI = true;

while($allLineItemsHaveI) {
   $lineItems[$i] = array();
   foreach($arr as $key => $subArr) {
      if(array_key_exists($i, $subArr)) {
         $lineItems[$i][$key] = $subArr[$i];
      } else {
         $allLineItemsHaveI = false;
      }
   } 

   $i++;
}    

array_pop($lineItems);

This is the output:

Array
(
    [0] => Array
        (
            [carat] => 6
            [units] => grams
            [weight] => 5
            [our_payout] => 15
            [sale_payout] => 18
            [hidden_carat] => 6
        )

    [1] => Array
        (
            [carat] => 5
            [units] => dwt
            [weight] => 3
            [our_payout] => 9
            [sale_payout] => 12
            [hidden_carat] => 5
        )

)
