In what scenarios might using aliases in SQL queries, like "AS idx", be beneficial when working with PHP arrays?

Using aliases in SQL queries can be beneficial when working with PHP arrays because it allows you to give custom names to columns in the result set. This can make the data more readable and easier to work with in your PHP code. Additionally, aliases can be used to rename columns to prevent naming conflicts or to simplify complex queries. 

<?php
// Assume $conn is a valid database connection

$sql = "SELECT id AS user_id, name AS user_name FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "User ID: " . $row["user_id"] . " - User Name: " . $row["user_name"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
