Get Sum of Values using array_combine?

Question

I am trying to count the total sum of values using array_combine. I have the duplicate key also, for example i have the array of emailid and array of product price.

$data1 = array("[email protected]","[email protected]","[email protected]");

and $data2 = array("100","200","300");

Now in $data1 i have two duplicate values as [email protected]

I am trying to use array_combine() It ignore the duplicate values and add the new one

I get this result as

[email protected] => 300;
[email protected] => 200;

But i want the result should be

[email protected] => (400)100+300;
[email protected] => 200;

Not sure how to get this result with array_combine Is something any alternatives to achieve this ?

Any Suggestion would be great.

array_combine simply won't help you here. It's trivial if you write a manual loop though. — deceze

Write a simple loop:

$result = array();

foreach ($data1 as $i => $v) {
  if (!isset($result[$v])) {
     $result[$v] = 0;
  }
  $result[$v] += $data2[$i];
}
