    $currentPage,    // current number of page
);

// Get some property directly
$p->totalEntries;

// Or by method call
$p->getTotalEntries();

Examples

Simple

             <-- previous page | next page -->
                   /                   \
           $p->prevPage            $p->nextPage

Advanced

                    $p->currentPage
                            |
        $p->prevPage        |           $p->nextPage
                \           |                /
        <<       <       6 [7] 8 9 10       >       >>
        /               /           \                \
$p->pageOfPrevSet      /             \    $p->pageOfNextSet
                      /               \
            $p->startOfSet       $p->endOfSet
                     |                |
                    [ $p->numbersOfSet ]

Statistics

                $p->totalPages
               /   $p->totalEntries
Total pages: 20   /
Total records: 200
Shown from 61 to 70 records
             \     \
              \     $p->startOfSlice + 1
               $p->endOfSlice + 1

Notes

• Most simple way to check, needs to show navigation panel or not, is checking $p->totalPages property. Needs only, if this property > 1.

• $p->prevPage, $p->nextPage, $p->pageOfPrevSet and $p->pageOfNextSet properties must be checked for null before using.
