What are the best practices for handling missing entries in a database query result in PHP?

Handling missing entries in a database query result in PHP can be done by checking if the result is empty or null before trying to access its values. This can prevent errors and ensure that your code runs smoothly even when there are no matching entries in the database. 

// Check if the query result is not empty before accessing its values
if ($result && mysqli_num_rows($result) > 0) {
    // Loop through the result set and fetch the data
    while ($row = mysqli_fetch_assoc($result)) {
        // Access the values from the database query result
        $value = $row['column_name'];
        // Process the data as needed
    }
} else {
    // Handle the case when no entries are found in the database query result
    echo "No entries found.";
}
