Bug description:php class vars have a bug in foreach
Description:
------------
class a{
public $s = array('a' => 'a%se');
function aa(){
foreach(range(1,5) as $v){
$this->s['a'] = str_replace('%s', $v, $this->s['a']);
var_dump($this->s);
}
}
}
$a = new a();
$a->aa();
result always:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
i think right:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a2e"
}
array(1) {
["a"]=>
string(3) "a3e"
}
array(1) {
["a"]=>
string(3) "a4e"
}
array(1) {
["a"]=>
string(3) "a5e"
}
Test script:
---------------
class a{
public $s = array('a' => 'a%se');
function aa(){
foreach(range(1,5) as $v){
$this->s['a'] = str_replace('%s', $v, $this->s['a']);
var_dump($this->s);
}
}
}
$a = new a();
$a->aa();
result always:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
i think right:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a2e"
}
array(1) {
["a"]=>
string(3) "a3e"
}
array(1) {
["a"]=>
string(3) "a4e"
}
array(1) {
["a"]=>
string(3) "a5e"
}
Expected result:
----------------
class a{
public $s = array('a' => 'a%se');
function aa(){
foreach(range(1,5) as $v){
$this->s['a'] = str_replace('%s', $v, $this->s['a']);
var_dump($this->s);
}
}
}
$a = new a();
$a->aa();
result always:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
i think right:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a2e"
}
array(1) {
["a"]=>
string(3) "a3e"
}
array(1) {
["a"]=>
string(3) "a4e"
}
array(1) {
["a"]=>
string(3) "a5e"
}
Actual result:
--------------
class a{
public $s = array('a' => 'a%se');
function aa(){
foreach(range(1,5) as $v){
$this->s['a'] = str_replace('%s', $v, $this->s['a']);
var_dump($this->s);
}
}
}
$a = new a();
$a->aa();
result always:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a1e"
}
i think right:
array(1) {
["a"]=>
string(3) "a1e"
}
array(1) {
["a"]=>
string(3) "a2e"
}
array(1) {
