我想使用PHP在html表中显示动态mysql垂直数据到水平。我的桌子就像
mysql> select * from role_perm;
-------------------------------------------
| id | userID | roleID | permID | value |
--------------- ---------------------------
| 1 | 2 | 1 | 1 | 1 |
|------------------------------------------
| 2 | 2 | 1 | 2 | 0 |
|------------------------------------------
| 3 | 2 | 1 | 3 | 0 |
|------------------------------------------
| 4 | 2 | 2 | 4 | 0 |
-------------------------------------------
| 5 | 2 | 2 | 1 | 1 |
|------------------------------------------
| 6 | 2 | 2 | 2 | 1 |
|------------------------------------------
| 7 | 2 | 2 | 3 | 0 |
|------------------------------------------
| 8 | 2 | 2 | 4 | 1 |
-------------------------------------------
| 9 | 5 | 1 | 1 | 1 |
|------------------------------------------
| 10 | 5 | 1 | 2 | 0 |
|------------------------------------------
| 11 | 5 | 1 | 3 | 0 |
|------------------------------------------
| 12 | 5 | 1 | 4 | 0 |
-------------------------------------------
依旧......
我希望在html表格中显示
----------------------------
| role | permissions |
----------------------------
| 1 | 1 | 2 | 3 | 4 |
----------------------------
| 2 | 1 | 2 | 3 | 4 |
----------------------------
| 3 | 1 | 2 | 3 | 4 |
-----------------------------
| 4 | 1 | 2 | 3 | 4 |
----------------------------

我想你可以用一个漂亮的MySQL查询来做到这一点(这应该对性能更好),但由于我不擅长SQL,这里是PHP解决方案:
$arrRoles = array();
while ($row = mysql_fetch_assoc($result)) {
if (!isset($arrRoles[$row['roleID']])) {
$arrRoles[$row['roleID']] = array();
}
$arrRoles[$row['roleID']][$row['permID']] = $row['value'];
}
var_dump($arrRoles);

试试这个:
SELECT
roleID AS role,
GROUP_CONCAT(DISTINCT permID ORDER BY permID ASC SEPARATOR '|') AS permissions
FROM role_perm
GROUP BY roleID
ORDER BY roleID
