How do I configure PHP to have permission to create directories and make files?

Question

I have a PHP script that receives uploads and it works fine in mamp, creating directories and receiving files as necessary, but when I move it to the server it errors out sa

Answer 1

The script must be able to write to the parent directory in order to create sub directories, so chmod 777 the parent directory, for instance httpdocs/uploads/ or wherever you are storing these files.

Answer 2

chown or chmod 777 the directories where the script wants to write (create) the files and NOT the script itself.

Answer 3

chmod("/somedir/somefile", 0777);
