Reported By: sirber at webernic dot com
Status: Open
Bug Type: Unknown/Other Function
Operating System: Linuix 2.6.13
PHP Version: 5.1.2
New Comment:
Same result with a copy of the array.
Source array and the copy are modified.
Reproduce code:
---------------
$aTmp = array();
$oTmp = new stdClass();
$oTmp->id = 1;
$aTmp[] = $oTmp;
$oTmp = new stdClass();
$oTmp->id = 2;
$aTmp3 = $aTmp
foreach ($aTmp3 as $iKey => $oTest)
$oTest->id = 'tea';
var_dump($aTmp, $aTmp3);
Expected result:
----------------
array(2) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
int(1)
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
int(2)
}
}
array(2) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
int(1)
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
int(2)
}
}
Actual result:
--------------
array(2) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
string(3) "tea"
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
string(3) "tea"
}
}
array(2) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
string(3) "tea"
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
string(3) "tea"
}
}

Description:
------------
When you foreach an array of object, if you modify the object, the
source is modified.
PHP4: work as expected
PHP5 with compatibility on: work as expected
PHP5: source gets modified
Reproduce code:
---------------
$aTmp = array();
$oTmp = new stdClass();
$oTmp->id = 1;
$aTmp[] = $oTmp;
$oTmp = new stdClass();
$oTmp->id = 2;
$aTmp[] = $oTmp;
$oTmp = new stdClass();
$oTmp->id = 3;
$aTmp[] = $oTmp;
$oTmp = new stdClass();
$oTmp->id = 4;
$aTmp[] = $oTmp;
foreach ($aTmp as $iKey => $oTest)
$oTest->id = 'tea';
var_dump($aTmp);
Expected result:
----------------
array(4) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
int(1)
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
int(2)
}
[2]=>
object(stdClass)#3 (1) {
["id"]=>
int(3)
}
[3]=>
object(stdClass)#4 (1) {
["id"]=>
int(4)
}
}
Actual result:
--------------
array(4) {
[0]=>
object(stdClass)#1 (1) {
["id"]=>
string(3) "tea"
}
[1]=>
object(stdClass)#2 (1) {
["id"]=>
string(3) "tea"
}
[2]=>
object(stdClass)#3 (1) {
["id"]=>
string(3) "tea"
}
[3]=>
object(stdClass)#4 (1) {
["id"]=>
string(3) "tea"
}
}
