[php-src] Issue #11244: Since PHP 8, throwing Exception inside recursive foreach loop causes reset of internal pointer
Issue: https://github.com/php/php-src/issues/11244
Author: survik1
### Description
Hello, we are finally pushing our code to PHP 8 and I have encountered this BC break which seems
more like bug than feature to me. This behavior is still present in 8.2 and the change was not
documented (unless i missed it ofc).

```php
<?php
$_ENV = [
'ZASIS_UI_BACKGROUNDCOLOR' => '#FFF1EC',
'ZASIS_UI_INFOPANEL_ENABLE' => '1',
'ZASIS_UI_INFOPANEL_TEXT' => 'DEBUG IS ON',
'ZASIS_UI_INFOPANEL_BACKGROUNDCOLOR' => '#F44',
];
$arr = [
'ui' => [
'backgroundColor' => 'ZASIS_UI_BACKGROUNDCOLOR',
'infoPanel' => [
'enable' => 'ZASIS_UI_INFOPANEL_ENABLE',
'text' => 'ZASIS_UI_INFOPANEL_TEXT',
'fontColor' => 'ZASIS_UI_INFOPANEL_FONTCOLOR',
'backgroundColor' => 'ZASIS_UI_INFOPANEL_BACKGROUNDCOLOR',
]
]
];
function loadEnv(&$data): void
{
if (is_array($data)) {
foreach ($data as $key => &$value) {
try {
loadEnv($value);
} catch (\InvalidArgumentException $e) {
unset($data[$key]);
}
}
} elseif (array_key_exists($data, $_ENV)) {
$data = $_ENV[$data];
} else {
throw new \InvalidArgumentException();
}
}
loadEnv($arr);
print_r($arr);
```
Output in PHP >=8.0:
```
Array
(
[ui] => Array
(
[backgroundColor] => #FFF1EC
[infoPanel] => Array
(
[backgroundColor] => #F44
)
)
)
```
Output in PHP >=7.1 <8.0:
```
Array
(
[ui] => Array
(
[backgroundColor] => #FFF1EC
[infoPanel] => Array
(
[enable] => 1
[text] => DEBUG IS ON
[backgroundColor] => #F44
)
)
)
```
