Runs the while loop at least once, regardless of whether or not the
while conditional evaluates to TRUE. Somewhat unrelated, but I used to
use this technique for looping through a result array from a
mysql_fetch_*() function if the internal array pointer has already been
bumped to the second position by a containing while loop. Now I just
use two result container variables instead of the same one, since it's
conceptually a little cleaner (than worrying about the array pointer's
position for two separate loops that overlap each other).

My experience with programming is limited, but I was under the
understanding that the @ sign should be used only suppress possible
unexpected error messages from users; that using it to suppress known
errors is really not as good a solution as finding out what is causing
the error and fixing it... of course, sometimes in a pinch you have to
MacGuyver the thing I guess. Just some advice :)
