I tried with this code but no luck :

foreach($users_all as $ukey => $usr){

        $totalearned = in_array($usr[1],$sumsales_all);
        var_dump(__LINE__,$usr[1], $totalearned);

    }

i'd say

foreach ($arr1 as $arr1item) {
        foreach ($arr2 as $arr2item) {
                if ($arr2item[1] == $arr1item['email']) $arr1item['total_earned']+=$arr2item[4];
   }
}

Open in new window


do I get it right that you want to get a person from arr1, then check if arr2 contains this person and if yes, then add the amount from field [4] of arr2 to the total_earned amount in arr1 for that person ?

No Radek,

I want to get the email from arr1, then check if arr2 contains this email and if yes, then add the [total_earned] of arr1 to the new element on arr1 for that email.

This is my expected result on arr2:

Array
    (
        [0] => Array
            (
                [0] => 8
                [1] => blanklou@gmail.com
                [2] => 
                [3] => Tay
                [4] => 0.00
                [5] => 2014-09-11 21:12:44
                [6] => 2014-09-15 07:02:51
                [7] => 13.15
            )
        [1] => Array
            (
                [0] => 9
                [1] => how.jimmy@gmail.com
                [2] => 
                [3] => How
                [4] => 0.00

                [7] => 6.14
            )
            .
            .
            .
            .

OK, i figured it out already. I use the following  code :
foreach($users_all as $ukey => $usr){
        
        foreach($sumsales_all as $skey => $sale){
            $match_email = in_array($usr[1],$sale);
            if($match_email){
                
                $users_all[$ukey][7] = (string)$sale['total_earned'];
            }
            
            
        }
        
    }
