When working with INNER JOIN in PHP, what are the recommended approaches for accessing columns from the joined tables to avoid conflicts?

When working with INNER JOIN in PHP, it is recommended to use table aliases to access columns from the joined tables to avoid conflicts. By assigning aliases to the tables involved in the join, you can specify which table a column belongs to when referencing it in your SQL query. This helps prevent ambiguity and ensures that the correct columns are retrieved from the joined tables. 

$query = "SELECT t1.column1, t2.column2
          FROM table1 AS t1
          INNER JOIN table2 AS t2 ON t1.id = t2.id";

// Execute the query and fetch results
$result = mysqli_query($connection, $query);

// Iterate through the results
while($row = mysqli_fetch_assoc($result)) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
