如何动态地将sql结果转换为多维数组？

Here is the query string.

这是查询字符串。

$query = "SELECT t.id, t.assignee, t.owner, 
            d.code, d.status, d.target_completion_date, 
            d.target_extension_date, d.submission_date, d.approval_date,
            d.revision_start_date, d.revision_completion_date, d.message, 
            ty.name, f.orig_name, f.new_name, 
            b.payment_date, b.discount, b.total_cost, b.amount_payed, b.edit_level, 
            b.billing_type, b.pages, b.words
      FROM tasks t
      INNER JOIN details d ON t.detail_id = d.id
      INNER JOIN billing b ON t.billing_id = b.id
      INNER JOIN TYPE ty ON d.document_type_id = ty.id
      INNER JOIN files f ON t.file_id = f.id
      WHERE t.assignee = 'argie1234'";
$query =
