Bug description:array_unique() misbehaves with array of DateTimes
Description:
------------
array_unique() returns duplicates for array which contains objects with
DateTime
instances.
Test script:
---------------
<?php
class Foo
{
public $dt;
function __construct($dt)
{
$this->dt = $dt;
}
}
$foo = new Foo(new DateTime);
$std = new stdClass;
$arr = [$foo, $foo, $std, $std, $std];
var_dump(array_unique($arr, SORT_REGULAR));
Expected result:
----------------
array(4) {
[0]=>
object(Foo)#1 (1) {
["dt"]=>
object(DateTime)#2 (3) {
["date"]=>
string(19) "2012-08-30 15:18:01"
["timezone_type"]=>
int(3)
["timezone"]=>
string(13) "Europe/Prague"
}
}
[2]=>
object(stdClass)#3 (0) {
}
}
Actual result:
--------------
array(4) {
[0]=>
object(Foo)#1 (1) {
["dt"]=>
object(DateTime)#2 (3) {
["date"]=>
string(19) "2012-08-30 15:18:01"
["timezone_type"]=>
int(3)
["timezone"]=>
string(13) "Europe/Prague"
}
}
[1]=>
object(Foo)#1 (1) {
["dt"]=>
object(DateTime)#2 (3) {
["date"]=>
string(19) "2012-08-30 15:18:01"
["timezone_type"]=>
int(3)
["timezone"]=>
string(13) "Europe/Prague"
}
}
[2]=>
object(stdClass)#3 (0) {
}
[4]=>

}
}
