How can one efficiently differentiate between data retrieved from two separate tables in PHP and set variables accordingly?

When retrieving data from two separate tables in PHP, you can efficiently differentiate between them by using aliases in your SQL query and then setting variables based on the table they belong to. By assigning unique aliases to each table in the query, you can easily identify which data comes from which table when fetching the results. 

// Assume $db is your database connection

// Query to retrieve data from two tables with aliases
$query = "SELECT table1.column1 AS data1, table2.column2 AS data2 FROM table1, table2 WHERE condition";

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

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        $data1 = $row['data1']; // Data from table1
        $data2 = $row['data2']; // Data from table2
        
        // Use the variables as needed
    }
} else {
    echo "Error: " . mysqli_error($db);
}
