Okay; thirty seconds' native intelligence.
I've got a string in $row_g['date']. When I echo it it outputs "2003-28-11". What does [man]date[/man] produce? Oh, a string in the specified format. So when I echo that it should output the string in the format I want.
Now, how to I get $row_g['date'] into bit of code I was given? Um, what's this bit "2003-28-11" there?

Actually, the code won't work because your date is in too unconventional a format (strtotime() would have expected "2003-11-28"). You'll need to use explode() to get the year, day and month separately. Then you can use mktime() to build a timestamp out of them that you can give to date() to format for you.
These extra contortions are a side-effect of not using the data types available: MySQL could have done it easily if you'd stored the date as a date...
