## Emojis to Words

1. json encode an emoji to get its surrogate pair

```
$surrogate_pair = json_encode(🌊);
print $surrogate_pair; //"\ud83c\udf0a"
```
2. The surrogate pair is the key in the array, check if the key exists and send back the associated keyword. The `$emojis_to_words` variable is an array you need to include in your project.
```
if(array_key_exists($surrogate_pair, $emojis_to_words)) {
	$keyword = $emojis[$surrogate_pair];
	print $keyword;
}
```
3. In this example `print $keyword` will show you "waves".
