How to upload string from mysql database to url?

Question

PHP

Here is the code

$bd = mysqli_connect('localhost', 'root', 'root', 'key'); // делаем коннект к базе данных

$sql = mysqli_query($bd, "SELECT number FROM `number`"); // $sql - переменная и делаем запрос ВЫБРАТЬ колонку(number) из Таблицы(number)
$row = mysqli_fetch_array($sql);  
//echo $row ['number']; // возвращаем строку
if (!$row) { // выполняем условие, если не срабатывает предыдущее.
  exit("Не возможно отобразить файл");

}


$path = substr ($_SERVER['PHP_SELF'],0,STRRPOS($_server['PHP_SELF'],"/"));

echo "<a href='http://localhost/".$_SERVER[''].$path."datatime.php?hash=".$row."'>http://localhost/".$_SERVER['HOST_HTTP'].$path."datatime.php?hash=".$row."</a>";

When I make a request, it displays
localhost/datatime.php?hash=Array
But I need to display the line itself from the database, how can I do this?

mysqli_fetch_array Function Fetches a single row from the result set and places it in an associative array, regular array, or both. Accordingly, you need to access the desired element of the array
