chmod 777 in php

Question

If I create a folder in php with mkdir() it has the www-data : www-data user and 755 permissions.

The problem is I can't delete this folder with the ftp-user (zapbe:psasrv) I tried to modify the folder with chmod($path, "0777") in php but this doesn't work.

How can I make the created folders and uploaded files readable / removeable for both the www-data and the ftp-user?

Answer 1

bool chmod ( string $filename , int $mode )

Within PHP they might be some limitations on the security, therefore the depending on your configuration it may not work.

The above function returns a booleon to let you know either it has succeed in changing the entities permissions.

if(!chmod($directory,0777))
{
    echo "Unable to chmod $direcotry";
}

Also a quote from PHP:

The current user is the user under which PHP runs. It is probably not the same user you use for normal shell or FTP access. The mode can be changed only by user who owns the file on most systems.

Understanding above you should look at chown
