### Description
The following code:
```php
<?php
$file = new SplTempFileObject();
// write to file
for ($i = 0; $i < 5; $i++) {
$file->fwrite("line {$i}" . PHP_EOL);
}
$file->rewind();
$file->next();
$file->next();
// read third line
var_dump($file->fgets());
// where am I?
echo $file->key(), ': ', $file->current();
```

Resulted in this output:
```
string(7) "line 0
"
3: line 0
```
But I expected (at least I think) this output instead:
```
string(7) "line 2
"
3: line 3
```
### PHP Version
PHP 8.20
### Operating System
