WhoAmI in PHP and getting Wordpress plugins to work without FTP

Hi all,

I was able to get WordPress up and running on my IBM i with relative ease
and now I want to install additional plugins. The issue is that if the user
profile used by the currently running script doesn't have access to the
folder where the plugin is going to be installed, then it will prompt you
for FTP login information.

Here is an article that talks about the issue:
http://hecode.com/why-wordpress-asks-for-connection-info-when-i-try-to-install-new-plugin/

In the article then recommend creating a simple php script with the
following:

echo exec('whoami');

I did that, and it is executing successfully (no ZendServer error logs or
warnings) but it returns blanks, so that doesn't help. I have even gone as
far as giving *PUBLIC all authority to the entire directory structure with
the following command (running V6R1):


CHGAUT OBJ('/www/zendsvr') USER(*PUBLIC) DTAAUT(*RWX) OBJAUT(*ALL)
SUBTREE(*ALL)


Still no go.

Anybody else resolve this?
