Question

$class = new Class;
$foo = json_decode($_POST['array']);

In this highly contrived example, I have a class with its own functions and variables, blah blah.

I also just decoded a JSON string, so those values are now in$foo. How do I move the elements in $foo over to $class, so that:

$foo->name becomes $class->name?

Would be trivial if I knew what all the elements were, yes… except for the sake of being dynamic, let’s say I want them all transferred over, and I don’t know their names.

You could use get_object_vars:

$vars = get_object_vars($foo);
foreach ($vars as $key => $value) {
    $class->$key = $value;
}

You could also implement this in your class:

public function bindArray(array $data) {
    foreach ($data as $key => $value) {
        $this->$key = $value;
    }
}

And then cast the object into an array:

$obj->bindArray( (array) $foo );

or add a method to do that too:

public function bindObject($data) {
     $this->bindArray( (array) $data );
}
