Welcome!.php

<?php

/**
 * Your start-up's BA has told marketing that your website has a large audience in Scandinavia and surrounding countries. 
 * Marketing thinks it would be great to welcome visitors to the site in their own language. Luckily you already use an API that 
 * detects the user's location, so this is an easy win.
 * 
 * The Task
 * 
 * Think of a way to store the languages as a database. The languages are listed below so you can copy and paste!
 * Write a 'welcome' function that takes a parameter 'language', with a type String, and returns a greeting - if you have it in your database. 
 * It should default to English if the language is not in the database, or in the event of an invalid input.
 * 
 * The Database
 * [ ("english", "Welcome")
 * , ("czech", "Vitejte")
 * , ("danish", "Velkomst")
 * , ("dutch", "Welkom")
 * , ("estonian", "Tere tulemast")
 * , ("finnish", "Tervetuloa")
 * , ("flemish", "Welgekomen")
 * , ("french", "Bienvenue")
 * , ("german", "Willkommen")
 * , ("irish", "Failte")
 * , ("italian", "Benvenuto")
 * , ("latvian", "Gaidits")
 * , ("lithuanian", "Laukiamas")
 * , ("polish", "Witamy")
 * , ("spanish", "Bienvenido")
 * , ("swedish", "Valkommen")
 * , ("welsh", "Croeso")
 * ]
 * 
 * Possible invalid inputs include:
 * IP_ADDRESS_INVALID - not a valid ipv4 or ipv6 ip address
 * IP_ADDRESS_NOT_FOUND - ip address not in the database
 * IP_ADDRESS_REQUIRED - no ip address was supplied
 *
