Answer 1

Your $row_array replaces every time and you get the last one. change your code to:

$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
    $row_array[$i]['title'] = $row['title'];
    $row_array[$i]['year'] = $row['year'];
    $row_array[$i]['author'] = $row['author'];
    $row_array[$i]['journal'] = $row['journal'];
    $row_array[$i]['keywords'] = $row['keywords'];
    $row_array[$i]['abstract'] = $row['abstract'];
    $row_array[$i]['url'] = $row['url'];
    $i++;
}

echo '{"data":';
    echo json_encode($row_array);
    echo '}';

Answer 2

You need to have a multi-dimensional array and you have taken a single dimensional array.

So, every time record comes, it overwrites older one.

Hence, you are getting the last record only.

Modify your code to:

$i=0;
$row_array = array();
while ($row = mysqli_fetch_assoc($result)) {
  $row_array[$i]['title'] = $row['title'];
  $row_array[$i]['year'] = $row['year'];
  $row_array[$i]['author'] = $row['author'];
  $row_array[$i]['journal'] = $row['journal'];
  $row_array[$i]['keywords'] = $row['keywords'];
  $row_array[$i]['abstract'] = $row['abstract'];
  $row_array[$i]['url'] = $row['url'];
  ++$i;
}

Answer 3

$row_array= array();
 while ($row = mysqli_fetch_assoc($result)) {
        $tmp = array();
        $tmp['title'] = $row['title'];
        $tmp['year'] = $row['year'];
        $tmp['author'] = $row['author'];
        $tmp['journal'] = $row['journal'];
        $tmp['keywords'] = $row['keywords'];
        $tmp['abstract'] = $row['abstract'];
        $tmp['url'] = $row['url'];
        $row_array[] = $tmp;
    }
echo '{"data":';
    echo json_encode($row_array);
    echo '}';

Answer 4

Your while loop keeps overwriting the same array elements in the $row_array array.

To do what you're trying to do: while($row = mysqli_fetch_assoc($result)) { $row_array[] = $row; }
