Merge “Defaults” array with “Input” array? PHP Which Function?

Question

Lets say you are having a user provide information.

Array 1

But not all is required. So you have defaults.

Array 2
         


        

Answer 1

$defaults = array(
    'some_key_1'=>'default_value_1',
    'some_key_2'=>'default_value_2',
);

$inputs = array_merge($defaults, $inputs)

Note that if the $inputs array contains keys not in the $defaults array they will be added in the result.
