尝试打印某些内容时出现语法错误（PHP/SQL）

Question

对于PHP/SQL，我是一个初学者/可怕的人，请牢记这一点。好了，我试图做的是打印一些“价值”或者你可以叫他们用PHP/SQL，像这样：

<?PHP 

require_once 
?> 

现在，这工作得很好。

Answer 1

只需添加它们就像添加了其他选定列。

require_once("dbb.php"); 
$SQL="select 
     date_format(timestamp,'%Y %M %d') as datum, 
     arena.namn as arena, 
     concat(hemma.lagnamn,'-',borta.lagnamn)as lag, 
     (select count(*) from mål where matchID=matchID and hemma.lagID=hemma) as h, 
     (select count(*) from mål where matchID=matchID and borta.lagID=borta)as b, 
     publiksiffror, 
     hemmagoal, 
     bortagoal 
    from 
     matcher 
    inner join 
     lag as hemma 
    on hemma.lagID = hemma 
    inner join 
     lag as borta 
    on borta.lagID = borta 
    inner join 
     arena 
    on matcher.arena=arena.arenaID;"; 

$result = mysql_query($SQL) or die(mysql_error()); 
while($rad = mysql_fetch_row($result)) 
{ 

echo "<tr>"; 
echo "<td>" . $rad[0] . "</td>"; 
echo "<td>" . $rad[2] . "</td>"; 
echo "<td>" . $rad[3] . "</td>"; 
echo "<td>" . $rad[4] . "</td>"; 
echo "<td>" . $rad[1] . "</td>"; 
echo "<td>" . $rad[5] . "</td>"; 
echo "</tr>"; 
} 


?>
