Lo he hecho así...que forma es mejor y por qué?
Código PHP:
$sql = "SELECT COUNT(*) AS total, COUNT(uno) AS uno,COUNT(dos) AS dos,COUNT(tres) AS tres,COUNT(cuatro) AS cuatro,COUNT(cinco) AS cinco,COUNT(seis) AS seis,COUNT(siete) AS siete,COUNT(ocho) AS ocho,COUNT(nueve) AS nueve,COUNT(diez) AS diez,COUNT(once) AS once,COUNT(doce) AS doce FROM p304 WHERE campus='Melilla'";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);
<td class="text_center"><?php echo $row['uno']; ?></td>
<td class="text_center"><?php echo $row['dos']; ?></td>
<td class="text_center"><?php echo $row['tres']; ?></td>
<td class="text_center"><?php echo $row['cuatro']; ?></td>
