What potential issue can arise when using mysqli_fetch_array within a loop in PHP?

When using mysqli_fetch_array within a loop in PHP, the potential issue that can arise is that the loop may continue iterating even after there are no more rows to fetch, leading to an infinite loop. To solve this issue, you can check if mysqli_fetch_array returns false, which indicates that there are no more rows to fetch, and break out of the loop.

$result = mysqli_query($connection, $query);

if ($result) {
    while ($row = mysqli_fetch_array($result)) {
        // process the row data
        
        // check if there are more rows to fetch
        if (!$row) {
            break;
        }
    }
}
