数组的输出总是等于'i'

Question

I have the variable $request. If i do vardump($request), I get the output of:

array(7) { 
    ["controller"]=> string(5) "index" 
    ["action"]=> string(5)"index" 
    ["module"]=> string(7) "default" 
    [2]=> array(8) { 
        ["g_goal_list_id"]=> string(3) "127" 
        ["textgoal"]=> string(9) "eats food" 
        ["task_0"]=> string(1) "0" 
        ["value_0"]=> string(5) "pukes" 
        ["task_1"]=> string(1) "0" 
        ["value_1"]=> string(0) "" 
        ["task_2"]=> string(1) "0"
        ["value_2"]=> string(0) "" 
    } 
    [3]=> array(10) { 
        ["g_goal_list_id"]=> string(3) "128" 
        ["textgoal"]=> string(9) "goes home" 
        ["task_0"]=> string(1) "0" 
        ["value_0"]=> string(20) "but never comes back" 
        ["task_1"]=> string(1) "0" 
        ["value_1"]=> string(14) "stays home now" 
        ["task_2"]=> string(1) "0" 
        ["value_2"]=> string(0) "" 
        ["task_3"]=> string(1) "0" 
        ["value_3"]=> string(0) "" 
    } 
    ["submit"]=> string(4) "Save" 
    ["task"]=> string(1) "5" 
}

which is all correct. However, I'm trying to use a foreach statment to grab values from the $request array and put them into a data array, and then submit that to the mysql db...

    foreach($request as $currentrow){
        //skips row if the field is empty
        if(strlen($currentrow['value']) < 1)//need to make sure I've defined $currentrow['value']
            continue;//skips row with empty field

        //I only need to grab the value/list_id/account_id from the form    
        $data = array('value' => $currentrow['value'],
            'g_goal_list_id' => $currentrow['g_goal_list_id'],
            'account_id' => g_getAccountId(),
            );
        var_dump($data);                

However, when I var_dump($data); my output looks like this:

array(3) { ["value"]=> string(1) "i" ["g_goal_list_id"]=> string(1) "i" ["account_id"]=> string(1) "1" }

array(3) { ["value"]=> string(1) "S" ["g_goal_list_id"]=> string(1) "S" ["account_id"]=> string(1) "1" }

array(3) { ["value"]=> string(1) "5" ["g_goal_list_id"]=> string(1) "5" ["account_id"]=> string(1) "1" }

The only thing that is correct in that var_dump($data) is the ["account_id"]

I'm thinking that my loop is incorrect, and I'm pretty bad with loops. Sooooo yeah, hopefully I included enough information. Thank you.

Huge thanks to @MonkeyZeus. I kept on getting an array that had the proper keys but all the values were null. Turns out I just needed to put my var_dump($data) inside of my loop, because when it was on the outside it was returning only the last array it looped thorough. On my form the last values it loops through were empty fields, that are meant for the user to add input. Also, I had to change 'g_goal_list_id' => $currentrow[$k]['g_goal_list_id'] to just 'g_goal_list_id' => $currentrow['g_goal_list_id']

foreach ($request as $k=> $currentrow) {
        $hit = false;
        $data = array();

        if(is_array($currentrow)){
            foreach ($currentrow as $k2 => $v2) {
                $explode = explode('_', $k2); //blows off the suffix of the $key
                //var_dump($explode);
                //$explode=substr($explode,2);
                //echo $k2;
                //echo '******';
                //echo $v2;
                echo $explode[0];
                echo '/';

                if($explode[0] == 'value'){
                    //echo "[" . $currentrow['g_goal_list_id'] . "]";
                    $hit = true;
                    $data = array(
                        'value' => $v2,
                        'g_goal_list_id' => $currentrow['g_goal_list_id'],
                        'account_id'=> g_getAccountId(),
                        );
                    continue;
                }
            var_dump($data);
            }

        }

        if ($hit === false){
            continue;
        }

        break;
    }
