In the provided PHP code, what are some best practices for handling and processing the query results using mysql_fetch_array?

When handling and processing query results using mysql_fetch_array in PHP, it is important to check if the query returned any results before trying to fetch them. This can be done by checking if the result is not false before proceeding with fetching the data. Additionally, it is a good practice to loop through the results using a while loop to fetch each row of data. 

// Check if the query returned any results
if ($result !== false) {
    // Loop through the results and fetch each row of data
    while ($row = mysql_fetch_array($result)) {
        // Process the data here
    }
} else {
    echo "No results found.";
}
