can't echo php class variable

Question

I want to write a php simple pagination class. Here is my code:

<?php
class Pagination {
public $rowsPerPage;
public $currentPage;
public $totalPages;
public $totalRows;
public $firstElement;
public $lastElement;


     public function paginate()
        { 
            if(isset($_GET['page'])){
                $this->currentPage  = $_GET['page'];     
            }           

                         $this->totalPages =  $this->totalRows/$this->rowsPerPage  ;
             return $this->totalPages;  

              $this->firstElement = $this->currentPage-1)*$this->rowsPerPage+1;
              return $this->firstElement;                
        }
}

$totalRecords = 55;
$paginator = new Pagination();
$paginator->totalRows = $totalRecords;
$paginator->rowsPerPage = 5;
$paginator->paginate();
echo $paginator->totalPages;
echo $paginator->firstElement;  
?>

I can echo $paginator->totalPages; but not $paginator->firstElement. What I do wrong ? Thanks

I have also _construct function public function _construct() { $this->rowsPerPage = 5; $this->currentPage = 1; $this->totalPages = 0; $this->totalRows = 40; $this->firstElement = 0; $this->lastElement = 0; } — user2359958

There is a syntatic error over ther in $this->firstElement you have a closing parenthesis, but not a opening. — Henrique Barcelos

Your paginate function has two return statements.

When the code hits the return $this->totalPages;, it will stop running the function. Therefore, the $this->firstElement = ... line is never ran.
