MySQL Count number of Items with Group By - php

Question

We have these two fields in our MySQL database:
in_model , in_color
And we are trying to count the total of model (in_model field), which has the same color (in_color field) in PHP with MySQL as backend database. We tried using the count() function, together with the group by. But it would seem we don't have achieve a desired result
This is our MySQL database:
$query = "SELECT in_model, COUNT(in_color) FROM in_newunit GROUP BY in_color,in_model";
$result = mysql_query($query) or die(mysql_error());
// Print out result
while($row = mysql_fetch_array($result)) {
echo "There are ". $row['COUNT(in_color)'] ."
". $row['in_model'] ." items.";
echo "<br />";
}
This is the output we are receiving
There are 1 C2I items.
There are 2 try items.
There are 2 try items.
There are 4 C2I items.
This is what we are trying to achieve
We are trying to have the color appear in the echo
There are 1 C2I Black items.
There are 2 try White items.
There are 2 try Black items.
There are 4 C2I White items.

Answer 1

I think this is straight enough. Try this.
$query = "SELECT in_model, in_color, count(*) AS counter FROM in_newunit GROUP BY in_model, in_color";
$result = mysql_query($query) or die(mysql_error());
// Print out result
while($row = mysql_fetch_array($result)) {
echo "There are ". $row['counter'] ." ". $row['in_model'] ." ".$row['in_color']." items.";
echo "<br />";
}

Answer 2

The query is actually the other way around:
SELECT in_color, count(*) FROM in_newunit
GROUP BY in_color
And you have actually said it yourself:
we are trying to count the total of model (in_model field), which has the same color (in_color field)
"count the total of model" > count(*)
"which has the same color" > for every color the previous count, which is a group by in_color
Also note that if you do count(in_model) you won't be counting values with in_model as null. If you do count(*) you will be counting the null values too. Up to you.
Update
So you want the amount of elements there are by (model, color) pair. Then this is the query:
SELECT in_model, in_color, count(*) FROM in_newunit
GROUP BY in_model, in_color
Eg:
model1 | black | 2
model1 | white | 1
model2 | black | 5
model3 | white | 4
