Submitted: 2015-10-08 11:51 UTC Modified: 2015-10-08 11:52 UTC
From: dmitry@php.net Assigned: dmitry
Status: Closed Package: Arrays related
PHP Version: 7.0Git-2015-10-08 (Git) OS: *
Private report: No CVE-ID:
 [2015-10-08 11:51 UTC] dmitry@php.net
Description:
------------
Comparison of references doesn't work properly when $strict argument is true.

Test script:
---------------
<?php
$arr = array(1, "1", "", NULL, 0, false, true, array());

$s = &$arr[0];
var_dump(array_keys($arr, $s, true));

$s = &$arr[1];
var_dump(array_keys($arr, $s, true));

$s = &$arr[2];
var_dump(array_keys($arr, $s, true));

$s = &$arr[3];
var_dump(array_keys($arr, $s, true));

$s = &$arr[4];
var_dump(array_keys($arr, $s, true));

$s = &$arr[5];
var_dump(array_keys($arr, $s, true));

$s = &$arr[6];
var_dump(array_keys($arr, $s, true));

$s = &$arr[7];
var_dump(array_keys($arr, $s, true));
?>


Expected result:
----------------
array(1) {
  [0]=>
  int(0)
}
array(1) {
  [0]=>
  int(1)
}
array(1) {
  [0]=>
  int(2)
}
array(1) {
  [0]=>
  int(3)
}
array(1) {
  [0]=>
  int(4)
}
array(1) {
  [0]=>
  int(5)
}
array(1) {
  [0]=>
  int(6)
}
array(1) {
  [0]=>
  int(7)
}


Actual result:
--------------
array(0) {
}
array(0) {
}
array(0) {
}
array(0) {
}
array(0) {
}
array(0) {
}
array(0) {
}
array(0) {
}
