How does the behavior of PHP mysqli differ when using store_result versus not using it, especially when transferring code to different servers or changing PHP versions?

When using PHP mysqli, the behavior can differ when using store_result versus not using it, especially when transferring code to different servers or changing PHP versions. The store_result method stores the result set in memory, which can be useful for large result sets or when needing to fetch rows multiple times. Without using store_result, the result set is fetched row by row, which can be less efficient. To ensure consistent behavior across different servers and PHP versions, it is recommended to use store_result when working with large result sets or needing to fetch rows multiple times. This can help avoid potential issues with memory management and performance.

```php
// Using store_result method
$result = $mysqli->query("SELECT * FROM table");
if ($result) {
    $result->store_result();
    while ($row = $result->fetch_assoc()) {
        // Process each row
    }
    $result->free();
}
```

By using store_result in this way, you can ensure consistent behavior when working with PHP mysqli across different servers and PHP versions.
