Development of API for iPhone Application

The task was assigned to the dev because of a need in API for iPhone application. The main goal of the script is to provide a possibility of communication between iPhone application and MySQL database. It accepts requests sent by iPhone application (with the help of Post or Get method) and handles them. There may be requests of two types: request for adding to the database and request for getting information from the database. When request for adding of information is received and after it is handled received information will be added to the database. And there will be given an xml response about correct acceptance of information (or about an error in case of any errors). In case request for getting of information from the database was received after it is handled there will be given requested information as an xml (or a message about an error in case of an error). Also while handling requests the script performed calculation functions (calculation of rating, etc.)
