Question

here’s the PHP/PDO.

    try {





    $query = 'SELECT Date,Close FROM DY_AAPL LIMIT 5';


    $sth = $db->prepare($query);
    $sth->execute();


    while ($row = $sth->fetch(PDO::FETCH_ASSOC)){

        $result_array=array();
        $result_array[]=$row['Close'];

    /*    $num = $row['Close'];    */

        echo json_encode($result_array);



    }


    }catch (PDOException $e){

        echo 'ERROR ' . $e->getMessage();
    }

When I attempt to access the array using javascript, it’s only outputting the last value in the array. Any pointers?

    <script type="text/javascript">

       var myjson = JSON.parse('<?php echo json_encode($result_array); ?>');

        document.write(myjson); 

    </script>

I thought it might have something to do with ‘JSON.parse,’ but I’m not sure. Thanks in advance!

Try

$result_array = array();

while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {

    $result_array[]=$row['Close'];

   /*    $num = $row['Close'];    */

}

echo json_encode($result_array);

…instead of initializing and outputting the array in each loop turn.
