PHP查找其他顶部文件夹中的文件是否存在

Question

What i want to do is find if a file in a different top folder exists.

Lets say I want to access the file this "page".html , I would have to access it like:

file_exists('../data/pages/this "page".html')

But that wont work, it just returns false. Any suggestions?

i am making a flat file cms, so filenames can have quotes. url: http://ffcms.comxa.com/admin user: tann98 pass: pswd

Thanks in advance.

Answer 1

Try this

file_exists('../data/pages/this%20"page".html');

%20 for space character

file_exists works on the file system and not via HTTP. So %20 will not be recognized as space but literally as %20 use spaces instead:

并确保使用dirname（ FILE ）真正从正确的文件夹开始-如果您的函数调用在包含的文件中，这很重要...

file_exists(dirname(__FILE__).'/../data/pages/this page.html')
