我在网页上打印出用户和头像，内容如下 代码，但希望还将用户余额添加到输出中 这是在另一个表中..尽管两个表共享用户 余额表中有未注册的用户 在用户信息表中
表用户信息
user | avatar |

表余额
user | balance |
------------------------------------------------------------
29758b15-e021-4b3b-aad7-088b3843a9f6| 1000 |
313b96f2-b9f1-4c8b-a3d0-5997d9a7bc1c| 0 |

$result = mysql_query("SELECT user,avatar FROM userinfo");
if (!$result) {
die("Query to show fields from table failed");
}
$fields_num = mysql_num_fields($result);
echo "<table><tr >";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo " <td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</font></td>";
echo "</tr>\n";
}
mysql_free_result($result);
最佳答案
select balance.user, info.avatar, balance.balance
from user_balance balance
left join user_info info on info.user = balance.user
关于php - 在另一个表中查找结果并在网页上打印出来，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27213370/
