How can PHP developers ensure accurate data retrieval when dealing with duplicate names in database queries?

When dealing with duplicate names in database queries, PHP developers can ensure accurate data retrieval by using aliases in their SQL queries to differentiate between the duplicate columns. By assigning unique aliases to each duplicate column, developers can retrieve the desired data without ambiguity. 

// Example SQL query with aliases to retrieve data from a table with duplicate names
$query = "SELECT t1.name AS first_name, t2.name AS last_name 
          FROM table t1 
          JOIN table t2 ON t1.id = t2.id";
$result = mysqli_query($connection, $query);

// Fetching data from the result set
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['first_name'] . " " . $row['last_name'] . "<br>";
}
