SQL Pivot Query中的PHP数组显示不同的数据

Question

我有一个SQL Server查询，它在SQL Server管理工具中显示以下结果：

   loc    L    M    S   XL
1  001    1    2    0    1
2  006    4    3    0    2
3  012    1    1    1    0
4  022    0    1    0    0

问题1：为了在网页上显示这个结果，我在PHP中创建了一个数组，但它显示了我不需要的更多数据（在每个大小（L，M，S，XL）之后有一个额外的数字数量再次显示）。

问题2：是否可以按照我可以定义的方式对尺寸进行排序？大小应该从小到大排序，如：S - M - L - XL，而不是按字母顺序排列。 （有时一个项目的大小以数字显示，从低到高完美排序，所以没问题。）

您应该使用FETCH_ASSOC指定您希望PDO返回关联数组

$sth->fetchAll(PDO::FETCH_ASSOC);

您应该能够使用usort以自定义方式排序https://secure.php.net/manual/en/function.usort.php
