How can ORDER BY "user" be used effectively in PHP to sort data from multiple tables alphabetically by user?

When sorting data from multiple tables alphabetically by user in PHP, you can use the ORDER BY clause in your SQL query to sort the results based on the "user" column. Make sure to join the tables properly and specify the column you want to sort by in the ORDER BY clause.

// Assuming you have connected to your database and selected the appropriate database

$query = "SELECT * FROM table1 
          JOIN table2 ON table1.user_id = table2.user_id 
          ORDER BY table1.user";

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

// Fetch and display the sorted results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['user'] . "<br>";
}
