PHP Output

Hi I have code to read from a mysql database and output the records. This is working but I want to group the output into subcategories. At the moment all records are being output one under the other. I need the code amended to have a heading(Sub Category) and then if there are, say, 5 records under this that they then appear. At the moment it looks like this Record 1: Category | Sub Category | Title | price etc Record 2: Category | Sub Category | Title | price etc Record 3: Category | Sub Category | Title | price etc I want it to look like: Sub Category 2 Record 1: Category | Sub Category | Title | price etc Record 3: Category | Sub Category | Title | price etc Sub Category 1 Record 2: Category | Sub Category | Title | price etc Hope this makes sense
