PHP检查文件存在而不知道扩展名

问题描述：

我需要检查文件是否存在，但是我不知道扩展名.

I need to check if a file exists but I don't know the extension.

我想做的IE:

if(file_exists('./uploads/filename')):
 // do something
endif;

当然没有用，因为它没有扩展名.扩展名将为jpg，jpeg，png，gif

Of course that wont work as it has no extension. the extension will be either jpg, jpeg, png, gif

有没有这样做的任何想法吗?

Any ideas of a way of doing this without doing a loop ?

答

您将必须执行 glob():

You would have to do a glob():

$result = glob ("./uploads/filename.*");

，然后查看$result是否包含任何内容.

and see whether $result contains anything.
