Other option is creating a new function( not yet available in PHP ) like: ``` array_check_scheme( array $array, array $scheme, bool $forced = false ): bool ``` ( name of function can be better ) in order to check types in arrays. Then you could: /** * @param array $args{name: string, surname: string, ?age: int} */ function my_function( array $args ) { $scheme = ['name' => 'string', 'surname' => 'string', '?age' => 'int'); $is_valid = array_check_scheme( $args, $scheme ); } my_function( ['name' = 'Nikita', 'surname' => 'Popov' ] ); //is_vaild = true my_function( ['name' = 'Nikita'] ); //is_vaild = false my_function( ['name' = 'Nikita'], 'age' => 10 ); //is_vaild = false A function like this could be useful in other contexts as well.
