1、先上图,看下实现效果
2、整类实现
class Page { private $total; //总数量 private $limit; //返回mysql的limit语句 private $pageStart; //开始的数值 private $pageStop; //结束的数值 private $pageNumber; //显示分页数字的数量 private $page; //当前页 private $pageSize; //每页显示的数量 private $pageToatl; //分页的总数量 private $pageParam; //分页变量 private $uri; //URL参数 /** * 分页设置样式 不区分大小写 * %pageToatl% //总页数 * %page% //当前页 * %pageSize% //当前页显示数据条数 * %pageStart% //本页起始条数 * %pageStop% //本页结束条数 * %total% //总数据条数 * %first% //首页 * %ending% //尾页 * %up% //上一页 * %down% //下一页 * %F% //起始页 * %E% //结束页 * %omitFA% //前省略加跳转 * %omitEA% //后省略加跳转 * %omitF% //前省略 * %omitE% //后省略 * %numberF% //固定数量的数字分页 * %numberD% //左右对等的数字分页 * %input% //跳转输入框 * %GoTo% //跳转按钮 */ private $pageType = '<span>第%page%页/共%pageToatl%页</span>%first%%up%%F%%omitFA%%numberF%%omitEA%%E%%down%%ending%'; //显示值设置 private $pageShow = array('first'=>'首页','ending'=>'尾页','up'=>'上一页','down'=>'下一页','GoTo'=>'GO'); /** * 初始化数据,构造方法 * @access public * @param int $total 数据总数量 * @param int $pageSize 每页显示条数 * @param int $pageNumber 分页数字显示数量(使用%numberF%和使用%numberD%会有不同的效果) * @param string $pageParam 分页变量 * @return void */ public function __construct($total,$pageSize=10,$pageNumber=5,$pageParam='p'){ $this->total = $totalpageSize = $pageSizepageNumber = $pageNumberpageParam = $pageParam; $this->calculate(); } /** * 显示分页 * @access public * @return string HTML分页字符串 */ public function pageShow(){ //$this->uri(); if($this->pageToatl>1){ if($this->page == 1){ $first = '<span>'.$this->pageShow['first'].'</span>'; $up = '<span>'.$this->pageShow['up'].'</span>'; }else{ $first = '<a href="'.%24this->uri.'&'.%24this->pageParam.'=1">'.$this->pageShow['first'].'</a>'; $up = '<a href="'.%24this->uri.'&'.%24this->pageParam.'='.(%24this->page-1).'">'.$this->pageShow['up'].'</a>'; } if($this->page >= $this->pageToatl){ $ending = '<span>'.$this->pageShow['ending'].'</span>'; $down = '<span>'.$this->pageShow['down'].'</span>'; }else{ $ending = '<a href="'.%24this->uri.'&'.%24this->pageParam.'='.%24this->pageToatl.'">'.$this->pageShow['ending'].'</a>'; $down = '<a href="'.%24this->uri.'&'.%24this->pageParam.'='.(%24this->page+1).'">'.$this->pageShow['down'].'</a>'; } $input = '<input type="text" value="'.$this->page.'" href="'.%24this->uri.'&'.%24this->pageParam.'='.%24startA.'">…'; } if($forStoppageToatl){ $omitE = '<span>…</span>'; $stopA = $this->page+$number>$this->pageToatl?$this->pageToatl:$this->page+$number; $omitEA = '<a href="'.%24this->uri.'&'.%24this->pageParam.'='.%24stopA.'">…</a>'; } } $this->pageType = str_ireplace(array('%F%','%E%','%omitFA%','%omitEA%','%omitF%','%omitE%','%numberF%','%numberD%'),array($F,$E,$omitFA,$omitEA,$omitF,$omitE,$numberF,$numberD),$this->pageType); } /** * 处理url的方法 * @access public * @param array $url 保持URL直对关系数组 * @return string 过滤后的url尾参数 */ private function uri(){ $url = $_SERVER["REQUEST_URI"]; $par = parse_url($url); if (isset($par['query'])) { parse_str($par['query'],$query); if(!is_array($this->uri)){ $this->uri = array(); } array_merge($query,$this->uri); unset($query[$this->pageParam]); while($key = array_search('',$query)){ unset($query[$key]); } $this->uri = $par['path'].'?'.http_build_query($query); }else{ $this->uri = $par['path'].'?'; } } /** * 设置limit方法及计算起始条数和结束条数 */ private function calculate(){ $this->pageToatl = ceil($this->total/$this->pageSize); $this->page = intval(@$_GET[$this->pageParam]); $this->page = $this->page>=1?$this->page>$this->pageToatl?$this->pageToatl:$this->page:1; $this->pageStart = ($this->page-1)*$this->pageSize; $this->pageStop = $this->pageStart+$this->pageSize; $this->pageStop = $this->pageStop>$this->total?$this->total:$this->pageStop; $this->limit = $this->pageStart.','.$this->pageStop; } /** * 设置过滤器 */ public function __set($name,$value){ switch($name){ case 'pageType': case 'uri': $this->$name = $value; return; case 'pageShow': if(is_array($value)){ $this->pageShow = array_merge($this->pageShow,$value); } return; } } /** * 取值过滤器 */ public function __get($name){ switch($name){ case 'limit': case 'pageStart': case 'pageStop': return $this->$name; default: return; } } }
