Why does PHP think this folder doesn't exist?

No such file or directory error using mkdir

and these solutions haven't worked for me. I still get Message: mkdir(): No such file or directory

I want to create a directory called 2018 with a subfolder 01 in a directory called folder_name. This is the path from the root when I enter $_SERVER['DOCUMENT_ROOT']: "/home/digits/www.url.com/app"

This is what I have tried

    $document_folder = $_SERVER['DOCUMENT_ROOT']."/".REPORT_FOLDER."/".date("Y")."/".date("m");

if(!is_dir($document_folder)){
     mkdir($document_folder, 0777);
}

Could someone take a look at this and see where I have gone wrong?

Answer 1

It seems the 2018 folder doesn't exist.

To automatically create both, the 2018 and the 2018/01folder, you need to pass true for $recursive (PHP: mkdir)

mkdir($document_folder, 0777, true);
