When I upload new files, their file name is stored into my database. I have been told that a couple of the file downloads weren't working. Upon further investigation I figured out that the file the person wanted to download was nowhere to be seen in my downloads directory. How can I determine if a file exists in my directory? I assume I can somehow use the location that is stored inside my database (ex: myfile.pdf) and compare that with what's in the folder.
I haven't had to do this but maybe this function would be helpful? file_exists(string $filename). There's a simple example if you scroll down the page a bit.
