Question

我在我的应用程序中使用文件读取功能。

有时我在打开和关闭文件时遇到异常，因为在文件名中我得到的是HTML字符串，我需要做些什么来保护应用程序或识别这个不正确的名字？

这是完整的堆栈错误。

Answer 1

您的fopen函数中包含太长的字符串。我也认为这不可能有效。您正在./upload/中查找名称为

的文件

<table cellspacing="0" cellpadding="0&quot ...

名称太长且无效。我认为你将变量传递给fopen函数，变量的内容不正确。

严重性：警告 - ＆gt; fopen（./ upload /＆lt; table cellspacing =“0”
