Testing

PHP Module
getResList(double LatMax, double LatMin, double LongMax, double
LongMin, int str, int end)
We can test this function on the PHP server side by using the following
URL:
http://rome.dynamiccreation.com/~admin22:8888/foodserver.php?function=get
ResList&LatMax=38&LatMin=37.3&LongMax=-121&LongMin=122&str=0&end=2
