Bug description: array operator [] has inconsistency when the array has
PHP_MAX_INT index value.
Description:
------------
The behavior of operator [] to the array is sometimes strange or hard to
describe the specification. For instance, the array which has two index,
2147483647 and -2147483648 on 32bit environment gets strange results. See
below example:
Reproduce code:
---------------
<?php
$array=array();
$array[-2147483648]=2;
$array[2147483647]=1;
$array[]=3;
var_dump($array);
$array=array();
$array[2147483647]=1;
$array[-2147483648]=2;
$array[]=3;
var_dump($array);
Expected result:
----------------
It should be same behavior. I think, the substitution to $array[] shuold
be both failed for this case.
Actual result:
--------------
PHP Warning: Cannot add element to the array as the next element is
already occupied in ./array-maxint-test.php on line 5
array(2) {
[-2147483648]=>
int(2)
[2147483647]=>
int(1)
}
array(3) {
[2147483647]=>
int(1)
[-2147483648]=>
int(2)
[-2147483647]=>
int(3)
}
