Grouping Arrays?

I'm not sure if you can do this.

I'm making a shoping cart, which uses Session, but for every quantity it takes the id number and adds it by one, so if i had product ID 1, but i wanted 10 quanty, it would show when i print it "1,1,1,1,1,1,1,1,1,1", is there anyway, when i use count($_SESSION['name']); it only counts one of the 1's? Same as if i had 10 2's or 10 3's?

Let me no if you get what i mean hehe, thanks for the help.

So, even if you have ten '2's, you don't want it to report "10" you want it to report "1"?

Post your code.

Yes Tyree, that is correct ;)

I'd recommend array_count_values() (http://www.php.net/array_count_values)
or array_unique() (http://www.php.net/array_unique)

I have used them both i get a error.

Al i need to do is count all the ones as one, and all twos as a two, etc etc.

If you did an array_count_values() on your array, couldn't you then just extract the keys that resulted to tell you the item IDs?


<?php
$array = array(1,1,1,1,2,2,2,3,3,3,3);

if (is_array($array)){

$sepValues = array_count_values($array);

print_r($sepValues);
print "<br />";
foreach ($sepValues AS $key=>$value)
{
print "Item: ".$key." Quantity: ".$value."&nbsp;&nbsp;&nbsp;";
}

}
?>


Output would be:
Array ( [1] => 4 [2] => 3 [3] => 4 )
Item: 1 Quantity: 4 Item: 2 Quantity: 3 Item: 3 Quantity: 4
