使用php更改html中的颜色

Question

<?php
    $id_pemesanan=$_GET['id_pemesanan'];

    $q="SELECT * FROM `seat`";
    $qe=mysql_query($q);
    $de=mysql_fetch_array($qe);

    $id_seat=$de['id_seat'];
    $row=$de['row'];
    $number=$de['number'];

    for ($i=1; $i <=$number ; $i++) { 
        echo "<li>
              <a href=\"book_seat_proses.php?id_pemesanan=".$id_pemesanan."&id_seat=".$id_seat."&number=".$i."\" id=".$row.$i."
              class=\"\"></a>
              </li>";
    }
?>

I'm trying to create a seat_booking system with three different color:

• white for available seat,
• black for reserved seat,
• green for your seat.

My plan is to add new class in a tag dynamically but I don't know how to do it.

You can do it like:

php:

for ($i=1; $i <=$number ; $i++) { 
    if( $status == 'available' )
    {
        echo '<a class="seat_available" href="...">Book Now</a>
    }
}

css:

.seat_available{
    color: green;
}
