What are the advantages of using fetch functions like mysql_fetch_assoc, mysql_fetch_array, and mysql_fetch_row in PHP when working with database results?

When working with database results in PHP, using fetch functions like mysql_fetch_assoc, mysql_fetch_array, and mysql_fetch_row can make it easier to retrieve and manipulate data from the database. These functions allow you to fetch rows from the result set in different formats (associative array, numeric array, or both) which can be useful depending on your specific needs. Additionally, these functions handle the fetching of data in a more streamlined and efficient manner compared to manually iterating through the result set. 

// Example of using mysql_fetch_assoc to fetch rows as associative arrays
$result = mysql_query("SELECT * FROM users");

while ($row = mysql_fetch_assoc($result)) {
    echo "User ID: " . $row['id'] . ", Username: " . $row['username'] . "<br>";
}
