Are there any specific best practices to keep in mind when joining multiple tables in PHP?

When joining multiple tables in PHP, it is important to use proper SQL syntax and aliases for table names to avoid ambiguity. Additionally, it is recommended to specify the columns you want to retrieve to improve performance and reduce the amount of data transferred. 

$query = "SELECT t1.column1, t2.column2 
          FROM table1 t1 
          JOIN table2 t2 ON t1.id = t2.table1_id";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0){
    while($row = mysqli_fetch_assoc($result)){
        // Process the retrieved data
    }
}
