Question

I have data here:

Array
(
[0] => Array
    (
        [SiteID] => 147
        [Amount] => 500.00
        [TransactionType] => D
    )

[1] => Array
    (
        [SiteID] => 147
        [Amount] => 500.00
        [TransactionType] => D
    )

[2] => Array
    (
        [SiteID] => 145
        [Amount] => 500.00
        [TransactionType] => R
    )
)

I’m done computing the reload, redemption and deposit and it’s working, but If ever the siteID don’t have a transaction of deposit [D] or reload [R ]or redemption [W] it should be equal to 0. my code is here:

   public function computeGHComponents()
    {
      error_reporting (E_ALL^ E_NOTICE);          

      foreach ($this->transaction as $t){

          $amount = (float) $t['Amount'];

            if (isset($this->totals[ $t['SiteID'] ][ $t['TransactionType'] ])){
                $this->totals[ $t['SiteID'] ][ $t['TransactionType'] ] += (float) $amount;
            } else {
                 $this->totals[ $t['SiteID'] ][ $t['TransactionType'] ] = (float) $amount;
            }
        }

     foreach($this->totals as $key => $value)


        {
          $this->result[$key] = array("Deposit"=>$value['D'], "Redemption"=>$value['W'], "Reload"=>$value['R']);

       }
     print_r($this->result); 

    } 

The result should be shown like this:

 Array
 (
[147] => Array
    (
        [Deposit] => 1000
        [Redemption] => 0
        [Reload] => 0
    )

[145] => Array
    (
        [Deposit] => 0
        [Redemption] => 500.00
        [Reload] => 0
    )

 )

Thanks in advance and Please guide me in proper way.

Answer 1

The description is vague, there is information missing in the question.
So this is kind of a blind shot, it might be what you ask but it might as well not:

In the assignment inside the last foreach, you can add 0 as a default value:

$this->result[$key] = array(
  "Deposit"    => array_key_exists('D',$value) ? $value['D'] : 0,            
  "Redemption" => array_key_exists('W',$value) ? $value['W'] : 0,           
  "Reload"     => array_key_exists('R',$value) ? $value['R'] : 0             
);
