PHP : file_put_contents failed on directory that created by mkdir

Question

(we use vps on centos linux, but working on subdomain)

Here is my problem:

On localhost in windows, it is just fine, but on intenet in linux, Why the file_put_contents doesn't work in directory that is created by mkdir ?

mkdir('suck', 0664, false);

file_put_contents('suck/stuck.php', 'the stick stack is stuck');

(The error is: failed to open stream: Permission denied in..)

Answer 1

The execution bit needs to be turned on in a folder to be able to manipulate it's contents by the affected user. See Why do directories need the executable (X) permission to be opened?

Answer 2

Directories should be executable by those you want to open them. Executable bit is the lowest order bit. Try this:

mkdir('suck', 0755, false);
