php 分页类(源码+实例)

分享一个php分页类，写的不错，提供了二个该分页类的调用实例，供大家学习参考。

1，php分页类代码

        Number        =    $number;
    $this->        N_p_p        =    $n_p_p; 
    $this->        Pages        =    ceil    (    $this->    Number    /    $this->    N_p_p    )    ; 
    $this->        Buttons        =    $buttons        ; 
    $page_number=    ($page_number>$this->Pages)    ?    $this->Pages    :    $page_number    ; 
    $this->        Page_number    =    $page_number    ; 
    $this->        Ret()    ; 
    } 

 public function Show_Pagination($link,$get='page',$div_class_name='pagination') 
    { 

    //if pages == 1 , no need to print pagination 
    if($this->Pages==1)return; 
    //$link is the addres of current page      
    //$get is name of get method 
    //echo pagination's div 
     
    echo'
'; 
    //echo pre button 
     
    if($this->Page_number>1)echo 'Page_number -1 ).'">Per '; 
    else echo 'Per '; 
     
    //print button
    $this->Buttons=(int)$this->Buttons;
    $start_counter    =    $this->Page_number-floor($this->Buttons/2);//for normal mode
    $end_conter        =    $this->Page_number+floor($this->Buttons/2);//for normal mode
    //try to buttons exactly equal to $Buttons    
    if($start_counter$this->Pages) $start_counter=$start_counter-($end_conter-$this->Pages);
    if(($this->Page_number-floor($this->Buttons/2))$this->Pages || $iPage_number)echo ' '.$i.' ';         // change current page' class 
     
else echo ' '.$i.' ';      // normal pages 
     
} 
      
    //echo next button 
     
    if($this->Page_numberPages)echo 'Page_number +1 ) .'">Nex '; 
     
    else echo 'Nex ';         
     
    //close div tag 
     
    echo'
'; 
     
    } 


    //give the page number and return start and end of selection  

 private function  Ret() 
    { 

    $this->Start=(($this->Page_number-1)*$this->N_p_p); 

    $this->End=  $this->N_p_p ; 

    } 
}

2，分页类的示例一

 
Start , $pagination->End"); 

//echo your result 
while($row=mysql_fetch_assoc($SecondQuery)) 
    { 
        echo 'id='.$row['id'].'
'; 
     
    }
//show pagination: 
$pagination->Show_Pagination("ExampleMysql.php?param1=value1",'page','pagination'); 
?>

3，分页类的调用示例二

 
Start , $cat->End 

//for show : 
$cat->Show_Pagination("example.php?",'page','pagination'); 
?>
