将结果从MYSQL查询推入数组

Question

I'm having trouble with the function below. Basically what it is supposed to do is check IF each item from the array ( $idDiscontinuedArray ) it's discontinued value from its respective table (either 1 or 0 ).

Now I'm not sure to push these answers in an array to make the next part more simpler. At the moment the its spits $rows out individually.

The result is: Array ( [discontinued] => 1, ) Array ( [discontinued] => 1 ) Array ( [discontinued] => 0 ) Array ( [discontinued] => 0 ) Array ( [discontinued] => 1 ).... where I would rather have Array [1] => 1 [2] => 1 [3] => 0 [4] => 0 [5] => 1....

The next part of the script is to check and see whether that ALL $rows = 1 which means end of script. If this is not the case this will run the function changeDiscontinued($dbh, $id, $idDiscontinuedArray) .

function checkDiscontinued($dbh, $idDiscontinuedArray) {
try {
    foreach ($idDiscontinuedArray as $id) {
        $stmt = $dbh->query("SELECT discontinued FROM `$id` ORDER BY `date` DESC LIMIT 1");
        $rows = $stmt->fetch(PDO::FETCH_ASSOC);
        print_r($rows);
        }
        if $rows['discontinued'] == TRUE) { 
            //echo $id . "Action if true";
        } else {
            changeDiscontinued($dbh, $id, $idDiscontinuedArray);
            echo $id . "Items already discontinued!";
            }       
    }
    catch (PDOException $e) {
    echo $e->getMessage();
    }
}

I Did not test this code, but it goes over prepared statements, and how to push items into an array. If you want more help, we can go into chat.

$discont = array();

function checkDiscontinued($dbh, $idDiscontinuedArray) {
try {
    foreach ($idDiscontinuedArray as $id) {
        $sql = $dbh->prepare("SELECT discontinued FROM $id ORDER BY `date` DESC LIMIT 1");
        $stmt = $sql->execute(array($id));
        $rows = $stmt->fetch(PDO::FETCH_ASSOC);
        print_r($rows);
        }
        if $rows['discontinued'] == TRUE) { 
            //echo $id . "Action if true";
        } else {
            changeDiscontinued($dbh, $id, $idDiscontinuedArray);
            echo $id . "Items already discontinued!";
            array_push($doscont, $id);
            }       
    }
    catch (PDOException $e) {
        echo $e->getMessage();
    }
}
