Create variables from POST

Question

I've got an old script here, which's based on the functionality that it creates variables from the POST Array. I know it's old and shouldn't be used, but which parameter do I need to activate it? `$_POST['output']` should automatically become `$output`. I've been searching on php.net and google, but I can't seem to find the name of this parameter.

Accepted Answer

Easy

```
extract($_POST);
```

Now

```
echo $output;
```

EDITS :

The above method has been deprected now. It can be achieved like this

```
extract(array_intersect_key($_POST, $array_of_expected_keys))
```
