Is it possible to use the count() function as an SQL command to determine the frequency of values in a database column?

Yes, it is possible to use the count() function in an SQL query to determine the frequency of values in a database column. You can use the count() function along with the GROUP BY clause to group the results by the values in the column and then count the occurrences of each value. This allows you to easily determine the frequency of each value in the column. 

$query = "SELECT column_name, COUNT(column_name) AS frequency FROM table_name GROUP BY column_name";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        echo $row['column_name'] . " appears " . $row['frequency'] . " times <br>";
    }
} else {
    echo "No results found.";
}
