countryCodeToEmoji.php

<?php
	// Assumes country code to already be uppercase
	function countryCodeToEmoji($cc) {
		return 
			mb_chr(127397 + ord($cc[0])) .
			mb_chr(127397 + ord($cc[1]));
	}

	// Makes sure the country code is uppercase
	function countryCodeToEmojiCaseSafe($cc) {
		$cc = strtoupper($cc);
		return 
			mb_chr(127397 + ord($cc[0])) .
			mb_chr(127397 + ord($cc[1]));
	}
	
	// This function generally makes some assumptions, like the string should be a valid country code.
	// This should be fine for most usecases
