Description:
------------
PHP 7.0.10 & 5.6.25

Key comparation in foreach loop not working as expected when keys are of mixed types (strings and ints)

If I use triple-equals operator (===) it works just fine, but it seems it should work with double-equals operator (==) as well.

Test script:
---------------
$array = array();

$array['word'] = "test 1";
$array['0'] = "test 2";
$array['1'] = "test 3";

foreach($array as $k=>$v) {
    var_dump($k);
    if($k == "word") {
        continue;
    }

    print_r($v);
}

Expected result:
----------------
C:\wamp64\www\tst\array_bug.php:10:string 'word' (length=4)
C:\wamp64\www\tst\array_bug.php:10:int 0
test 2
C:\wamp64\www\tst\array_bug.php:10:int 1
test 3

Actual result:
--------------
C:\wamp64\www\tst\array_bug.php:10:string 'word' (length=4)
C:\wamp64\www\tst\array_bug.php:10:int 0
C:\wamp64\www\tst\array_bug.php:10:int 1
test 3
