Question

I am using a foreach loop on an array of rows in a model file in CodeIgniter.
What i want to do is reflect the changes i make in every row ,in the foreach loop ,to the original array.

        $unique = $this->db->get_where('list', array('item_index' => $item));
        foreach ($unique->result_array() as $row)

            {
                $row["status"]= "Not Unique";
            if($row["bid_amount"]==$amount)
                {
                    if($count==0){ $row["status"]="Unique and Final"; }
                    else {$row["status"]="Unique but Not Final"; }

                }

                $count++;

            }   
        return $unique;

I am adding another attribute to each row here and i want to echo this attribute corresponding to each row in a view file.
But i am getting error Undefined index: status.
How can i possibly reflect the changes in the array to be returned.

Assign the result_array() to a variable, iterate over it, but change the original array and not the local one. PHP’s foreach comes in two flavours:

foreach($arr as $value) and foreach($arr as $key => $value)

Try this:

$results = $unique->result_array();
foreach ($results as $rK => $rV){
    $results[$rK]["status"]= "Not Unique";
    //other stuff.
}
return $results;

Alternatively, you can pass by reference:

foreach ($results as &$result) {
    $result['status'] = "Not Unique";
}

See the PHP docs on arrays. Specifically Example 10.
