Do you need to manually reset mysql_errno to null in PHP?

Yes, you may need to manually reset mysql_errno to null in PHP after executing a query to ensure that any previous error codes are cleared before executing another query. This can help prevent confusion or errors caused by lingering error codes. 

// Execute a query
$result = mysqli_query($connection, "SELECT * FROM table");

// Check for errors and reset mysql_errno
if (!$result) {
    // Handle error
    $error_code = mysqli_errno($connection);
    mysqli_free_result($result);
    mysqli_next_result($connection); // Move to the next result set
    mysqli_errno($connection); // Reset mysql_errno
}
