How can aliasing fields in PHP MySQL queries impact sorting and data retrieval?

Aliasing fields in PHP MySQL queries can impact sorting and data retrieval because when you alias a field, the original field name is no longer accessible in the result set for sorting or retrieval. To solve this issue, you can use the original field name in the ORDER BY clause or when accessing the data in the result set. 

$query = "SELECT id AS user_id, name AS user_name FROM users ORDER BY id ASC";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    echo $row['user_id'] . " - " . $row['user_name'] . "<br>";
}
