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 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 sub_pages) {
			$current_array = array ();
			for ($i = 0; $i pageNums; $i++) {
				$current_array[$i] = $i +1;
			}
		} else {
			$current_array = $this->initArray();
			if ($this->current_page current_page pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1) {
				for ($i = 0; $i pageNums) - ($this->sub_pages) + 1 + $i;
				}
			} else {
				for ($i = 0; $i 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] ";

			$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) {

		$a = $this->construct_num_Page();
		for ($i = 0; $i current_page) {
				$subPageCss2Str .= "  " . $s . "  ";

				http://blog.csdn.net/tangcheng_ok/article/details/$url = $this->subPage_link . $s;

			}

		if ($this->current_page pageNums) {
			http://blog.csdn.net/tangcheng_ok/article/details/$lastPageUrl = $this->subPage_link . $this->pageNums;

			$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
