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
