本文为大家分享了两段PHP分页类,很实用,供大家参考,具体内容如下
<?php class Page { private $total; //总记录 private $pagesize; //每页显示多少条 private $limit; //limit private $page; //当前页码 private $pagenum; //总页码 private $url; //地址 private $bothnum; //两边保持数字分页的量 //构造方法初始化 public function __construct($_total, $_pagesize) { $this->total = $_total ? $_total : 1; $this->pagesize = $_pagesize; $this->pagenum = ceil($this->total / $this->pagesize); $this->page = $this->setPage(); $this->limit = "LIMIT ".($this->page-1)*$this->pagesize.",$this->pagesize"; $this->url = $this->setUrl(); $this->bothnum = 2; } //拦截器 private function __get($_key) { return $this->$_key; } //获取当前页码 private function setPage() { if (!empty($_GET['page'])) { if ($_GET['page'] > 0) { if ($_GET['page'] > $this->pagenum) { return $this->pagenum; } else { return $_GET['page']; } } else { return 1; } } else { return 1; } } //获取地址 private function setUrl() { $_url = $_SERVER["REQUEST_URI"]; $_par = parse_url($_url); if (isset($_par['query'])) { parse_str($_par['query'],$_query); unset($_query['page']); $_url = $_par['path'].'?'.http_build_query($_query); } return $_url; } //数字目录 private function pageList() { for ($i=$this->bothnum;$i>=1;$i--) { $_page = $this->page-$i; if ($_page < 1) continue; $_pagelist .= ' <a href="'.$this->url.'&page='.$_page.'">'.$_page.'</a> '; } $_pagelist .= ' <span class="me">'.$this->page.'</span> '; for ($i=1;$i<=$this->bothnum;$i++) { $_page = $this->page+$i; if ($_page > $this->pagenum) break; $_pagelist .= ' <a href="'.$this->url.'&page='.$_page.'">'.$_page.'</a> '; } return $_pagelist; } //首页 private function first() { if ($this->page > $this->bothnum+1) { return ' <a href="'.$this->url.'">1</a> ...'; } } //上一页 private function prev() { if ($this->page == 1) { return '<span class="disabled">上一页</span>'; } return ' <a href="'.$this->url.'&page='.($this->page-1).'">上一页</a> '; } //下一页 private function next() { if ($this->page == $this->pagenum) { return '<span class="disabled">下一页</span>'; } return ' <a href="'.$this->url.'&page='.($this->page+1).'">下一页</a> '; } //尾页 private function last() { if ($this->pagenum - $this->page > $this->bothnum) { return ' ...<a href="'.$this->url.'&page='.$this->pagenum.'">'.$this->pagenum.'</a> '; } } //分页信息 public function showpage() { $_page .= $this->first(); $_page .= $this->pageList(); $_page .= $this->last(); $_page .= $this->prev(); $_page .= $this->next(); return $_page; } } ?>
分页样式如下图所示:
使用说明:
<?php $_page = new Page($_total,$_pagesize); //其中 $_total 是数据集的总条数,$_pagesize 是每页显示的数量. ?>
第二个分页类:
<?php /** * page.class.php 分页类 * 日期:2015-04-05 * http://aowana.sinaapp.com */ class page { public static $url; public static $page; public static $total; public static $size; public static $number; public static $max; public static $action = array('previous', 'number', 'next'); public static function show($url, $page, $total, $size=10, $number=11) { self::$url = $url; self::$page = $page; self::$total = $total; self::$size = $size; self::$number = $number; self::$max = ceil($total / $size); $str = ''; foreach (self::$action as $name) $str .= self::$name(); return $str; } public static function first() { if (self::$page > 2) { $url = self::url(1); return "<li id=\"pbfirst\"><a href=\"{$url}\" title=\"首页\">首页</a></li>"; } } public static function previous() { if (self::$page > 1) { $url = self::url(self::$page - 1); return "<li id=\"pbprevious\"><a href=\"{$url}\" title=\"上一页\">上一页</a></li>"; } } public static function number() { $str = ''; $f = self::$number % 2 ? (self::$number - 1) / 2 : self::$number / 2; $s = self::$page - $f; $e = self::$page + $f; if (self::$page < ($f + 1)) { $s = 1; $e = self::$number; $e = $e > self::$max ? self::$max : $e; } if (self::$page > (self::$max - $f)) { $s = self::$max - self::$number; $s = $s < 1 ? 1 : $s; $e = self::$max; } for ($i=$s; $i<=$e; $i++) { $url = self::url($i); if ($i == self::$page) $str .= "<li><strong>{$i}</strong></li>"; else $str .= "<li><a href=\"{$url}\" title=\"第{$i}页\">{$i}</a></li>"; } return $str; } public static function next() { if (self::$page < self::$max) { $url = self::url(self::$page + 1); return "<li id=\"pbnext\"><a href=\"{$url}\" title=\"下一页\">下一页</a></li>"; } } public static function end() { if ((self::$max - self::$page) > 1) { $url = self::url(self::$max); return "<li id=\"pbend\"><a href=\"{$url}\" title=\"末页\">末页</a></li>"; } } public static function url($page) { return str_replace('{page}', $page, self::$url); } }
以上就是本文的全部内容,希望对大家学习php程序设计有所帮助。
