How can the issue of the UPDATE query not functioning properly in conjunction with ORDER BY be resolved in PHP?

When using an UPDATE query with ORDER BY in PHP, the ORDER BY clause is not supported in UPDATE statements. To work around this issue, you can use a subquery to first select the rows in the desired order, then update them accordingly. 

// Connect to the database
$conn = new mysqli($servername, $username, $password, $dbname);

// Select the rows to update in the desired order
$sql = "SELECT * FROM your_table WHERE condition ORDER BY column_name";
$result = $conn->query($sql);

// Loop through the selected rows and update them
while($row = $result->fetch_assoc()) {
    $id = $row['id'];
    // Perform your update operation here
    $update_sql = "UPDATE your_table SET column_name = 'new_value' WHERE id = $id";
    $conn->query($update_sql);
}

// Close the database connection
$conn->close();
