Bug description: Using current/next/prev/key on the same array as foreach() is
currently looping
Description:
------------
If I use current/next/prev/key() on the same array as foreach() is
currently looping over the internal pointer is only increased on the first
iteration.
However. If I compare the value ($b) to something before using
current/next/prev/key() I get the expected results:
$a = range(0, 10);
foreach($a as $b) {
if($b == 5) {
var_dump(current($a)); // int(6)
}
}
Reproduce code:
---------------
<?php
$a = range(0, 10);
foreach($a as $b) {
var_dump(current($a));
if($b == 5) {
var_dump(current($a));
}
}
Expected result:
----------------
int(1)
int(2)
int(3)
int(4)
int(5)
int(6) // The var_dump() inside the if()
int(6)
int(7)
int(8)
int(9)
int(10)
bool(false) // Since the internal pointer points beyond the end
Actual result:
--------------
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
int(1)
