Returns the first element of an array or `NULL` if an array is empty. ### array\_value\_last [](#array_value_last) Function described in [PHP RFC](https://wiki.php.net/rfc/array_key_first_last) but was not accepted. Returns the last element of an array or `NULL` if an array is empty. ### array\_value [](#array_value) Returns element of an array by key otherwise null. ### array\_value\_string [](#array_value_string) Returns *ONLY STRING* element of an array by key otherwise null. ### array\_value\_int [](#array_value_int) Returns *ONLY INTEGER* element of an array by key otherwise null. ### array\_value\_bool [](#array_value_bool) Returns *ONLY BOOL* element of an array by key otherwise null. ### array\_value\_float [](#array_value_float) Returns *ONLY FLOAT* element of an array by key otherwise null. ### array\_value\_array [](#array_value_array) Returns *ONLY ARRAY* element of an array by key otherwise null.
