How can aliases be used to avoid conflicts in PHP scripts involving JOIN statements?

Aliases can be used in PHP scripts involving JOIN statements to avoid conflicts when columns have the same name in multiple tables. By assigning aliases to the columns in the SELECT statement, you can distinguish between them and prevent ambiguity. This allows you to retrieve the desired data from the tables without encountering errors due to column name conflicts. 

$query = "SELECT t1.column_name AS alias1, t2.column_name AS alias2
          FROM table1 AS t1
          JOIN table2 AS t2 ON t1.id = t2.id";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        echo $row['alias1'] . ' - ' . $row['alias2'] . '<br>';
    }
}
