尝试打印内容时出现语法错误 (PHP/SQL)

Question

当谈到 PHP/SQL 时，我是 beginner/terrible，请记住这一点。好的，所以我想做的是打印一些 "values" 或任何你可以用 PHP/SQL 称呼它们的东西，就像这样：

<?PHP

require_once
 ?>

现在一切正常。

Answer 1

就像添加其余 select 列一样添加它们。

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>";
 }  


 ?>
