Bug description: extract($a, EXTR_OVERWRITE|EXTR_REFS) can fail to create
references to $a
Description:
------------
Using extract() with EXTR_OVERWRITE|EXTR_REFS does not create references
to the array elements if the following conditions are true:
- $a is referenced by some other variable (its is_ref flag is true).
- A variable already exists in the current scope with a name matching the
key.
This is reproducible on 5.2, 5.3 and 6.0 snaps.
Reproduce code:
---------------
<?php
$a = array('foo' => 'original.foo');
$foo = 'test';
$ref = &$a;
extract($a, EXTR_OVERWRITE|EXTR_REFS);
$foo = 'changed.foo';
var_dump($a['foo']); //expecting changed.foo
?>
Expected result:
----------------
string(11) "changed.foo"
Actual result:
--------------
string(12) "original.foo"
