Эквивалент MySQL

Question

У меня есть это:

$rs = mysql_query('select zip  from _zipcode where zip like "'.$consulta .'%"');

Как я могу преобразовать код выше в mysqli?

Я пробовал что-то подобное, но не завершено

($sql = $db -> prepare('select zip from _zipcode where zip // ));

Answer 1

Ваша линия:

     $rs = mysql_query('select zip  from _zipcode where zip like "'.$consulta .'%"');

Линия SQLi:

        $query="select zip  from _zipcode where zip like " .$consulta . "%";
        $rs = mysqli_query($connection_information,$query) or  die(mysqli_error($connection_information));
       $row_rs = mysqli_fetch_assoc($rs);
       $totalRows_rs = mysqli_num_rows($rs);

    do {  
        echo $row_rs['zip'];

        } while ($row_rs = mysqli_fetch_assoc($rs));
          $rows = mysqli_num_rows($rs);
          if($rows > 0) {
           mysqli_data_seek($rs, 0);
           $row_rs = mysqli_fetch_assoc($rs);
                          }

Answer 2

if($sql = $db->prepare('select zip from _zipcode where zip like ?'))
{
    $sql->bind_param("s", $consulta);
    $sql->execute();
    $sql->bind_result($zip);

    while ($sql->fetch()) {
        echo "Zip: $zip\n";
    }

    $sql->close();
}
