Re: Two new functions array_first() and array_last()

I thought of it after sending the email, so I'll post it again. By combining my two ideas, I think I can come up with a smarter proposal. ``` array_first(array $array, int|string &$key = null) ``` If you want to accurately determine whether an array is empty or not, you can satisfy your request by checking if the key is null. Users who do not think accurate determination is necessary can omit the second argument. And if you also want a key, it can fulfill that request as well. Regards. Saki
