### Description
The following code:
```php
<?php
var_dump((new SQLite3(':memory:'))
->query('SELECT 1 AS key,2 AS key')
->fetchArray(SQLITE3_ASSOC));
```
Resulted in this output, for PHP 8.2.*:
```
array(2) {
["key"]=>
int(1)
["key"]=>
int(2)
}
```
But I expected this output instead, like PHP 8.1.20 and earlier:
```
array(1) {
["key"]=>
int(2)
}
```
These duplicate keys are propagated by
json_encode(), serialize(), ...
resulting in invalid JSON, for example.
### PHP Version
PHP 8.2.7
### Operating System
FreeBSD 13.1-RELEASE-p6
