the best method would be to put the information into an array, then use array_slice() to reference a specific 'page' of that information. the array_slice() offset and length parameters function exactly the same as a LIMIT clause in a mysql based pagination query.

assuming you have or have written a database based pagination script, it is doing two things. 1) getting a total count of the number of data items, and 2) retrieving the correct 'page' of data to display.

 

to accomplish pagination for an array of data, you would first get all your data into an array, in the order that you want the data. then, to accomplish item #1, you would use count() on the array of data. to accomplish item #2, you would use array_slice() on the array of data, using the offset and length (number of rows per page) values normally going into the LIMIT clause in a database query as the parameters going into the array_slice() statement. you would then loop over the array of data that the array_slice() statement returned to produce the output on the page.

 

to get your array of data ordered the way you want, you can either use php's usort() or array_multisort() statements. examples of using these are in the php.net documentation and posted all over the web.
