Answer 1

//you just need to put the name of the column in quert like COUNT(column_name)
$con = mysql_connect("localhost","root","root");
if (!$con){
die("Can not connect: " . mysql_error());
}
mysql_select_db("mydb",$con);
//data base connection ends here
//you write a query to fire if you want by order the put "ORDER BY HERE"
$query = "select acc_class,count(acc_class) as total from mytable group by acc_class";
//here you fire a query to mysql
$result = mysql_query($query);
//now put the selected roe in loop and again and again loop ask for more data to mysql
while($record = mysql_fetch_array($result)){
**//here you select all the group in the table**
echo '<br>';
echo "<label>" . $record['acc_class'] . "</label>";
echo "<label>" . $record['total'] . "</label>";
}
//close connection to database
mysql_close($con);

Answer 2

Please dump $values:
var_dump($values);
I guess, the problem is it's either the data itself or the data-fetch (array, assoc).
Please format your SQL for better readability:
SELECT acc_class, COUNT(*) AS total FROM mytable GROUP BY acc_class;
The Count statement is correct: https://dev.mysql.com/doc/refman/5.7/en/counting-rows.html
Solution:
$query = "SELECT acc_class, COUNT(*) AS total FROM mytable GROUP BY acc_class";
$result = mysql_query($query);
echo '<table border="1">';
while($row = mysql_fetch_array($result)) {
echo '<tr>';
echo '<td>' . $row['acc_class'] . '</td>';
echo '<td>' . $row['total'] . '</td>';
echo '</tr>';
}
echo '</table>';
