php自己写的好看的分页类

  1 pageSize = $pageSize; 19         $this->showPage = $showPage; 20         $this->count    = $count; 21         $this->page     = $this->checkPage($currentPage); 22         $this->mergyStr = ''; 23         $this->skip     = $skip; 24     } 25  26     //检查传递的$page的合法性 27     public function checkPage($currentPage) { 28          if($currentPage < 1 || empty($currentPage)) { 29              $currentPage = 1; 30          } 31         if($currentPage > $this->totalPages()) { 32             $currentPage = $this->totalPages(); 33         } 34         return $currentPage; 35     } 36  37     //计算偏移量 38     public function pageOffset() { 39         return ($this->showPage-1)/2; 40     } 41  42     //计算总页数 43     public function totalPages() { 44         return ceil($this->count/$this->pageSize); 45     } 46  47     //获取页面URL 48     public function getPageUrl() { 49         $CurrentUrl = $_SERVER["REQUEST_URI"]; 50         $arrUrl     = parse_url($CurrentUrl); 51         $urlQuery   = $arrUrl["query"]; 52  53         if($urlQuery){ 54             //print_r($this->page); 55             $urlQuery  = preg_replace("/(^|&)page=/" . $this->page, "", $urlQuery); 56             $CurrentUrl = str_replace($arrUrl["query"], $urlQuery, $CurrentUrl); 57  58             if($urlQuery){ 59                 $CurrentUrl.="&page"; 60             } 61             else $CurrentUrl.="page"; 62  63         } else { 64             $CurrentUrl.="?page"; 65         } 66  67         return $CurrentUrl; 68     } 69  70     //页码显示行 71     public function GetPagerContent() { 72         $start = 1; 73         $end   = $this->totalPages(); 74         $this->mergyStr .= ""; 75         if($this->page > 1) { 76             $this->mergyStr .= " getPageUrl()."="."1'>首页"; 77             $this->mergyStr  .= " getPageUrl()."=".($this->page-1)."'>上一页"; 78         }else{ 79             $this->mergyStr .= " 首页"; 80             $this->mergyStr  .= " 上一页"; 81         } 82  83         if($this->totalPages() > $this->showPage) { 84             if($this->page > $this->pageoffset()+1) { 85                 $this->mergyStr .= "..."; 86             } 87  88             if($this->page > $this->pageoffset()) { 89                 $start = $this->page-$this->pageoffset(); 90                 $end = $this->totalPages() > $this->page+$this->pageoffset() ? $this->page+$this->pageoffset() : $this->totalPages(); 91             } 92             else{ 93                 $start = 1; 94                 $end = $this->totalPages() > $this->showPage ? $this->showPage : $this->totalPages(); 95             } 96  97             if($this->page + $this->pageoffset() > $this->totalPages()) { 98                 $start = $start - ($this->page + $this->pageoffset() - $end); 99             }100 101         }102 103         for($i=$start; $i<=$end; $i++) {104             if($i == $this->page) {105                 $this->mergyStr .= "{$i}";106             }else{107                 $this->mergyStr .= " getPageUrl()."=".$i."'>{$i}";108             }109 110         }111 112         if($this->totalPages() > $this->showPage && $this->totalPages() > $this->page + $this->pageoffset()) {113             $this->mergyStr  .= "...";114         }115 116         if($this->page < $this->totalPages()) {117             $this->mergyStr .= " getPageUrl()."=".($this->page+1)."'>下一页";118             $this->mergyStr .= " getPageUrl()."=".$this->totalPages()."'>尾页";119         }else{120             $this->mergyStr .= " 下一页";121             $this->mergyStr  .= " 尾页";122         }123 124         $this->mergyStr .= " 共{$this->totalPages()}页";125 126         //显示跳转框127         if($this->skip == true) {128             $this->mergyStr .= $this->skipNumPage();129         }130 131         $this->mergyStr .= "";132 133         print_r($this->mergyStr);134     }135 136     //跳转页137     public function skipNumPage() {138         $this->mergyStr .= "";142     }143 144 }

上面是类文件的所有代码，以下是调用实例：

";echo "follow_trade_idfollow_id";while($rs = mysql_fetch_assoc($query)) {    echo "{$rs['follow_trade_id']}{$rs['follow_id']}";}echo "";//读取分页条$p->GetPagerContent();

样式CSS:

效果如图所示：
