Show Different Content Depending On URL Paramaters

I am looking for someone that can help me write IF statements on a web page depending on the variables in the URL. The URL structure will be something like this example.com/706a96b2bd30743a21139a1edc7941fea50737af0a2ae94&inf_field_BrowserLanguage=en-US%2Cen%3Bq%3D0.5&inf_field_FirstName=John&inf_field_LastName=Smith&inf_field_Email=johnsmith%40mailinator.com&inf_field_Phone1=&inf_custom_CWTREGuestFirstName=&inf_custom_CWTREGuestLastName=&inf_CsRm7DQb8dDDAANq=&inf_option_Event=7790&inf_option_Areyoubringingaguest=7798 I want the page to show different things depending on the variables in the URL above. EG "hello inf_field_FirstName" IF inf_option_Event=7790 AND Areyoubringingaguest=7798 { We can't wait to see you and your guest in India } IF inf_option_Event=7792 AND Areyoubringingaguest=7750 { We can't wait to see you and your child guest in Norway } I would prefer it to be in PHP as I think this is the easiest way to achieve this.
