This must be an integer greater than 0.

Note

Notă:

dirname() operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".

Notă:

dirname() is locale aware, so for it to see the correct directory name with multibyte character paths, the matching locale must be set using the setlocale() function.
