The following should get you going in the right direction. As shown, this works on PHP3 as well as PHP4: <?PHP

        $mytable = array( .... );

        $pagesize = 5 ; // records per page
        $tablesize = count( $mytable );
        $tablestart = 0 ;

        if ( isset( $pageindex ) )
        {
                // url to this page was specified with an offset
                $tablestart = ($pageindex -1 ) * $pagesize ;
        }
        else
        {
                $pageindex = 1 ;
        }

        if ( ( $tablestart > $tablesize ) || ( $tablestart < 0 ) )
        {
                // something is wrong - visitor probably screwing with their
                // URL.  You could display an error -- or just reset to page 1
                $pageindex = 1;
                $tablestart = 0;
        }

        // some function to print your table from the defined startpoint to the
        // number of elements to print, checking for possible array termination
        // within this range (i.e. if the array doesn't fall on an exact
        // pagesize boundary, there may not be a full table here).
        // yup, YOU get to do some of your own work - your question was how to
        // deal with putting the data on separate pages, not how to display it.
        displaymytable( $mytable, $tablestart, $pagesize )

        // emit "previous" and "next" links (or you might display a whole
        // range of direct page links).

        if ( $pageindex > 1 )
        {
                print( '<a href="' . $PHP_SELF . '?pageindex=' );
                print( $pageindex - 1 . '">Prev</A>');
        }

        if ( ( $tablestart + $pagesize ) < $tablesize )
        {
                print( '<a href="' . $PHP_SELF . '?pageindex=' );
                print( $pageindex + 1 . '">Next</A>');
        }
