这是一款php分页代码是一款经典的可自动判断url参数再进行分页的实例代码,同时自定了上页,下页,首页,尾页,同时还支持select下拉框跳转代码.
php 经典的分页代码类代码如下:
class page{ var $page_name = "page" ; var $next_page = '下一页' ; var $pre_page = '上一页' ; var $first_page = '首页' ; var $last_page = '尾页' ; var $pre_bar = '<<' ; var $next_bar = '>>' ; var $format_left = '' ; var $format_right = '' ; var $pagebarnum =5; var $totalpage =0; var $nowindex =1; var $url = "" ; var $offset =0; var $rewrite = array (); function page( $array ) { if ( is_array ( $array )){ if (! array_key_exists ( 'total' , $array )) $this ->error(__function__, 'need a param of total' ); $total = intval ( $array [ 'total' ]); $perpage =( array_key_exists ( 'perpage' , $array ))? intval ( $array [ 'perpage' ]):10; $nowindex =( array_key_exists ( 'nowindex' , $array ))? intval ( $array [ 'nowindex' ]): '' ; $url =( array_key_exists ( 'url' , $array ))? $array [ 'url' ]: '' ; $action = ( array_key_exists ( 'action' , $array )) ? $array [ 'action' ] : '' ; $id0 = ( array_key_exists ( 'id0' , $array )) ? $array [ 'id0' ] : '' ; $id1 = ( array_key_exists ( 'id1' , $array )) ? $array [ 'id1' ] : '' ; $id2 = ( array_key_exists ( 'id2' , $array )) ? $array [ 'id2' ] : '' ; $id3 = ( array_key_exists ( 'id3' , $array )) ? $array [ 'id3' ] : '' ; } else { $total = $array ; $perpage =10; $nowindex = '' ; $url = '' ; $action = '' ; $id0 = '' ; $id1 = '' ; $id2 = '' ; $id3 = '' ; } if ((! is_int ( $total ))||( $total <0)) $this ->error(__function__, $total .
