Description:
------------
bug #29992 did not prove that the array was being modified by foreach,
however this code does. According to var_dump() the last element starts
as a "string" and after the foreach is a "reference to a string".
Reproduce code:
---------------
$foo = array('three', 'blind', 'mice');
var_dump($foo);
foreach($foo as &$elmnt){}
var_dump($foo);
Expected result:
----------------
array(3) {
[0]=>
string(5) "three"
[1]=>
string(5) "blind"
[2]=>
string(4) "mice"
}
array(3) {
[0]=>
string(5) "three"
[1]=>
string(5) "blind"
[2]=>
string(4) "mice"
}
Actual result:
--------------
array(3) {
[0]=>
string(5) "three"
[1]=>
string(5) "blind"
[2]=>
string(4) "mice"
}
array(3) {
[0]=>
string(5) "three"
[1]=>
string(5) "blind"
[2]=>
&string(4) "mice"
}
