Adding in ability to specifiy scope would be highly useful for Objects.

What's the deal to use extract() to add dynamically member variables to
the object?

It's still not a bug as extract() was never meant to do this. Making it
a feature-request.

Note to anyone that says that the extra two lines aren't a big deal:
it's a lot more than two if you need to emulate some of the more
sophisticated (and rather useful) features of extract().

Description:
------------
extract() cannot be used inside an object member function to set object
var's. Using extract normally brings the variables into the scope of
the function (as expected), but there is no way to bring array key/value
pairs to object scope without a foreach statement.
It would be nice to specify what scope the variables should be created
in, or even create a different function specifically to set the member
variables of an object.
Reproduce code:
---------------
class MyClass
{
var $m1; // Imagine a class with fifty variables,
var $m2; // Not all of which must be set.
var $m3; // This is why you would want to use extract().
function Init($info)
{
extract($info, EXTR_OVERWRITE); // Doesn't work; extracted to
function scope
extract($info, EXTR_PREFIX_ALL, "$this->"); // Stupid idea; not
a valid variable name
foreach($info as $key => $value)
{
$this->$key = $value; // Works, but ugly
}
}
}
