db privileges

Hey all,

I ran across a problem while trying to run a delete query.  The website that
I am working on has multiple users in the db for various logins and I was
inadvertently using a less-privileged account and found I couldn't make
delete queries run successfully.  I eventually found out the problem and
changed the db connection but I was wondering if there is a php function
and/or mysql function that can be run from php to find out the privileges
for a particular db connection.  Any ideas?

PHP Ver. 5.2.1
MySQL Ver. 5.0.27
on Linux

Thanks
