unexpected changes - overriding object inside foreach php - php

Question

I've got array of object form database like below:
array(3) {
[1]=>
array(2) {
[0]=>
object(stdClass)#99 (3) {
["id"]=>
string(2) "42"
["name"]=>
string(4) "NAME1"
["type"]=>
string(1) "6"
}
[1]=>
object(stdClass)#98 (3) {
["id"]=>
string(3) "146"
["name"]=>
string(3) "STH1"
["type"]=>
string(1) "2"
}
}
[2]=>
array(2) {
[0]=>
object(stdClass)#97 (3) {
["id"]=>
string(2) "422"
["name"]=>
string(4) "NAME2"
["type"]=>
string(1) "3"
}
[1]=>
object(stdClass)#96 (3) {
["id"]=>
string(3) "16"
["name"]=>
string(3) "STH2"
["type"]=>
string(1) "2"
}
}
[3]=>
array(2) {
[0]=>
object(stdClass)#95 (3) {
["id"]=>
string(2) "11"
["name"]=>
string(4) "NAME3"
["type"]=>
string(1) "5"
}
[1]=>
object(stdClass)#94 (3) {
["id"]=>
string(3) "69"
["name"]=>
string(3) "STH3"
["type"]=>
string(1) "3"
}
}
}
And if i want to add the same object to the next array and change value of its type, i override the current object. How can i fix it? My foreach loop below:
foreach($events as $key => $event){
foreach($event as $k => $v){
if($v->type == 6){
$v->type = "0";
$events[$key+1][] = $v;
$v->type = "6";
}
}
}

If my guess what you are trying to achieve is right i would go like this
foreach($events as $key => $event){
foreach($event as $k => $v){
if($v->type == 6){
$tmp = $v;
$tmp->type="0";
$events[$key+1][] = $tmp;
}
}
}
