What are the advantages of using aliases in SQL queries when converting DateTime values to Timestamps in PHP?

When converting DateTime values to Timestamps in PHP using SQL queries, using aliases can make the code more readable and easier to maintain. Aliases can be used to rename the converted values in the SQL query, making it clear what each value represents. This can help avoid confusion and errors when working with multiple DateTime values in the same query. 

// Example of using aliases in SQL query to convert DateTime values to Timestamps
$query = "SELECT UNIX_TIMESTAMP(created_at) AS created_timestamp, UNIX_TIMESTAMP(updated_at) AS updated_timestamp FROM table_name";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    echo "Created Timestamp: " . $row['created_timestamp'] . "<br>";
    echo "Updated Timestamp: " . $row['updated_timestamp'] . "<br>";
}
