Dynamically count the remain of items max 5 per line

[ragy]

Hello,
i have many categories, each category have one or more items inside it. i'm displaying each category and its items under it in lines with max number of items per line.
ex:
(the data coming from database dynamically).

Category 1

item1    item2    item3    item4    item5

item6    item7 

or

Category 2

item1    item2 

the question is :
Using PHP how to know the remain numbers of items in the line [ If i have 2 items under the category how to know that it remains 3 to complete the line and if i have 1 item under the category, how to know that it remains 4 to complete the line and so on]

i want to know how many items remains in the row.

i do not know how many categories or items exist.

please i want it as quickly as possible

Sure. Just count it when you get the information from the database.

For example, mysql_num_rows($query_result) will tell you the number of matches (total).

Or if you are using a while/for loop, you can simply count how many times you find a match.
