PHP分页实现（附效果图）

首先一个分页类，如下（摘自网络）可拷贝直接使用

each_disNums = intval($each_disNums);		$this->nums = intval($nums);		if (!$current_page) {			$this->current_page = 1;		} else {			$this->current_page = intval($current_page);		}		$this->sub_pages = intval($sub_pages);		$this->pageNums = ceil($nums / $each_disNums);		$this->subPage_link = $subPage_link;		$this->show_SubPages($subPage_type);		//echo $this->pageNums."--".$this->sub_pages;	}	/*	  __destruct析构函数，当类不在使用的时候调用，该函数用来释放资源。	 */	function __destruct() {		unset ($each_disNums);		unset ($nums);		unset ($current_page);		unset ($sub_pages);		unset ($pageNums);		unset ($page_array);		unset ($subPage_link);		unset ($subPage_type);	}	/*	  show_SubPages函数用在构造函数里面。而且用来判断显示什么样子的分页	 */	function show_SubPages($subPage_type) {		if ($subPage_type == 1) {			$this->subPageCss1();		}		elseif ($subPage_type == 2) {			$this->subPageCss2();		}	}	/*	  用来给建立分页的数组初始化的函数。	 */	function initArray() {		for ($i = 0; $i < $this->sub_pages; $i++) {			$this->page_array[$i] = $i;		}		return $this->page_array;	}	/*	  construct_num_Page该函数使用来构造显示的条目	  即使：[1][2][3][4][5][6][7][8][9][10]	 */	function construct_num_Page() {		if ($this->pageNums < $this->sub_pages) {			$current_array = array ();			for ($i = 0; $i < $this->pageNums; $i++) {				$current_array[$i] = $i +1;			}		} else {			$current_array = $this->initArray();			if ($this->current_page <= 3) {				for ($i = 0; $i < count($current_array); $i++) {					$current_array[$i] = $i +1;				}			}			elseif ($this->current_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1) {				for ($i = 0; $i < count($current_array); $i++) {					$current_array[$i] = ($this->pageNums) - ($this->sub_pages) + 1 + $i;				}			} else {				for ($i = 0; $i < count($current_array); $i++) {					$current_array[$i] = $this->current_page - 2 + $i;				}			}		}		return $current_array;	}	/*	 构造普通模式的分页	 共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]	 */	function subPageCss1() {		$subPageCss1Str = "";		$subPageCss1Str .= "共" . $this->nums . "条记录，";		$subPageCss1Str .= "每页显示" . $this->each_disNums . "条，";		$subPageCss1Str .= "当前第" . $this->current_page . "/" . $this->pageNums . "页 ";		if ($this->current_page > 1) {			http://blog.csdn.net/tangcheng_ok/article/details/$firstPageUrl = $this->subPage_link . "1";			http://blog.csdn.net/tangcheng_ok/article/details/$prewPageUrl = $this->subPage_link . ($this->current_page - 1);			$subPageCss1Str .= "[首页] ";			$subPageCss1Str .= "[上一页] ";		} else {			$subPageCss1Str .= "[首页] ";			$subPageCss1Str .= "[上一页] ";		}		if ($this->current_page < $this->pageNums) {			http://blog.csdn.net/tangcheng_ok/article/details/$lastPageUrl = $this->subPage_link . $this->pageNums;			http://blog.csdn.net/tangcheng_ok/article/details/$nextPageUrl = $this->subPage_link . ($this->current_page + 1);			$subPageCss1Str .= " [下一页] ";			$subPageCss1Str .= "[尾页] ";		} else {			$subPageCss1Str .= "[下一页] ";			$subPageCss1Str .= "[尾页] ";		}		echo $subPageCss1Str;	}	/*	 构造经典模式的分页	 当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]	 */	function subPageCss2() {		$subPageCss2Str = "";		$subPageCss2Str .= "当前第" . $this->current_page . "/" . $this->pageNums . "页 ";		if ($this->current_page > 1) {			http://blog.csdn.net/tangcheng_ok/article/details/$firstPageUrl = $this->subPage_link . "1";			http://blog.csdn.net/tangcheng_ok/article/details/$prewPageUrl = $this->subPage_link . ($this->current_page - 1);			$subPageCss2Str .= "  首页  ";			$subPageCss2Str .= "  上一页  ";		} else {			$subPageCss2Str .= "  首页  ";			$subPageCss2Str .= "  上一页  ";		}		$a = $this->construct_num_Page();		for ($i = 0; $i < count($a); $i++) {			$s = $a[$i];			if ($s == $this->current_page) {				$subPageCss2Str .= "  " . $s . "  ";			} else {				http://blog.csdn.net/tangcheng_ok/article/details/$url = $this->subPage_link . $s;				$subPageCss2Str .= "  " . $s . "  ";			}		}		if ($this->current_page < $this->pageNums) {			http://blog.csdn.net/tangcheng_ok/article/details/$lastPageUrl = $this->subPage_link . $this->pageNums;			http://blog.csdn.net/tangcheng_ok/article/details/$nextPageUrl = $this->subPage_link . ($this->current_page + 1);			$subPageCss2Str .= "  下一页  ";			$subPageCss2Str .= "  尾页  ";		} else {			$subPageCss2Str .= "  下一页  ";			$subPageCss2Str .= "  尾页   ";		}		echo $subPageCss2Str;	}}?>

在需要分页的php文件中

include_once ("Pagination.php");//每页显示的条数$pageSize = 10;//总条目数$pageTotal = $db->get_var("select count(*) from tb");//每次显示的页数$sub_pages = 10;//得到当前是第几页if (is_array($_GET) && count($_GET) > 0) {	if (isset ($_GET["p"])) { //是否存在"id"的参数		$pageCurrent = $_GET["p"];	}} else {	$pageCurrent = 1;}$goodses = $db->get_results("SELECT g.id,* FROM tb as g INNER JOIN (select id from tb  order by updatetime desc limit " . ($pageCurrent -1) * $pageSize . ",10 )as g1 ON g.id=g1.id");

显示分页数据
