Question

我正在尝试创建一个符号，其中写入多个表，这些表由每个表的主键链接。因此，它查询它写入第一个表的内容，以找到要插入第二个表的自动递增主键。

但是我一直在说错误：

解析错误：语法错误，意外T_ENCAPSED_AND_WHITESPACE，在第79行期待T_STRING或T_VARIABLE或T_NUM_STRING

但我找不到错误。

提前感谢您的帮助。

Answer 1

解析错误：语法错误，意外T_ENCAPSED_AND_WHITESPACE，在第79行期待T_STRING或T_VARIABLE或T_NUM_STRING

源于

'$row5['unitid']'在VALUES中应为'$row5[unitid]'。

将查询结果插入表中
