PHP script to add data to SQL database

Need a php script that will parse and verify data passed to it from URL into SQL database and hashes the values to verify the values submitted. For example: [login to view URL] VerificationHash is calculated from string before it using MD4 or some other hashing method. In above example this was hashed then added at the end of the URL "AddEntry=True&DataBaseTable=NamesTable&FirstName=Value&LastName=Value&VariablePhoneNumber=Value&Address=Value&EmailAddress=Value" If URL values after being hashed by PHP script don't match hash provided then put the string into different database named "Rejected". When values are added to the database need to timestamp the newly entered data.
