Remove a member from an object?

Question

Is there a simple way to remove a member from an object? Not just set it to null, but actually remove it.

Thanks! :)

Edit: I've already tried unset(), and setting the member variable to null obviously doesn't work. I suppose I could convert the object to an array, then remove the array key in question, and convert back to an object, but blech... There's got to be an easier way!

Answer 1

You are using RedBean. Just checked it out. And these bean objects don't have actual properties.

unset($bean->field);

Does not work, because ->field is a virtual attribute. It does not exist in the class. Rather it resides in the protected $bean->properties[] which you cannot access. RedBean only implements the magic methods __get and __set for retrieving and setting attributes.

This is why the unset() does not work. It unsets a property that never existed at that location.

Answer 2

$obj = new stdClass;
$obj->answer = 42;
print_r($obj);
unset($obj->answer);
print_r($obj);

Works fine for me. Are you sure you 're doing it right?

Update:

It also works for properties defined in classes:

class Foo {
    public $bar = 42;
}

$obj = new Foo;
print_r($obj);
unset($obj->bar);
print_r($obj);
