Php 致命错误：未捕获PDO异常：SQLSTATE[HY093]：无效参数编号：

我知道有很多问题是相似的，但没有一个能解决我的问题。我正在将多张图片上载到我的数据库。我没有直接上传到数据库。我正在存储到一个文件夹中。这是我的php代码

我已经检查了我的所有代码。但是没有出现任何错误。

删除所有类似于

物理（class8）

的括号，并使其类似于

物理\u class8

参数应该是简单的字符串。请去掉括号。很快，先生……但我不明白……请你标记一下好吗@艾恩伯格先生<代码>：物理（class8）对于占位符来说太复杂了。更改字符串以消除括号，例如

：physics

谢谢…它可以工作！！我的名声不到15.对不起
