[nycphp-talk] Help with error statement

I have the start of a zipcode radius locator.  It seems to work but  
the problem I am having is creating an error statement if no  
locations are found.  At first it made sense to check for retuned  
zipcode values.  The problem being one zipcode will always be  
returned the one that is used for the search.  So my thinking would  
be to uses the retuned query that actually looks for the locations :  
$sql_events = mysql_query("SELECT * FROM area36 WHERE zipcode  
='$key'") or die (mysql_error());  .  However anything I try seems to  
loop and create ugly things.

I am a rank beginner far better photographer than coder so talk  
simple.  My brain is also a little tired after seeing Ziggy Marley  
last night as you might expect, so I apologize up front for my  
sluggish brain.
