Question

I have a weird problem. On my development server all stuff works but on the live server it doesn’t. I have a folder with a special char like “ö” in it. On the development server i do this to check if the filename is a directory ($dir = “coördinatie”):

 if (is_dir(urldecode($dir)))
  echo "true";
 else {
  echo "false";
 }

The result is true. On the live server the result is false. The weird thing is… a hardcoded string works fine and the result is true. Like this:

 if (is_dir("coördinatie"))
  echo "true";
 else {
  echo "false";
 }

I tried typecasting to string and such but i can’t figure it out. Hope someone has a clue.

Answer 1

My guess would be this:

urldecode generally decodes to UTF-8.
Your hardcoded string may be in Latin-1, since the source code is saved as such.
The file system (functions) on your local machine like Unicode, the ones on production like Latin-1.

You may have to convert the string into an encoding that your file system expects.
You can confirm my suspicion by comparing the values of bin2hex for both strings.
