PHP分頁實現（附效果圖）

首先一個分頁類，如下（摘自網絡）可拷貝直接使用

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析構函數，當類不在使用的時候調用，該函數用來釋放資源。
	 */
	function __destruct() {
		unset ($each_disNums);
		unset ($nums);
		unset ($current_page);
		unset ($sub_pages);
		unset ($pageNums);
		unset ($page_array);

		unset ($subPage_type);
	}

	/*
	  show_SubPages函數用在構造函數裡面。而且用來判斷顯示什麼樣子的分頁
	 */
	function show_SubPages($subPage_type) {
		if ($subPage_type == 1) {
			$this->subPageCss1();
		}
		elseif ($subPage_type == 2) {
			$this->subPageCss2();
		}
	}

	/*
	  用來給建立分頁的數組初始化的函數。
	 */
	function initArray() {
		for ($i = 0; $i < $this->sub_pages; $i++) {
			$this->page_array[$i] = $i;
		}

	}

	/*
	  construct_num_Page該函數使用來構造顯示的條目
	  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 {

			} else {

					$current_array[$i] = $this->current_page - 2 + $i;
				}
			}
		}

		return $current_array;
	}

在需要分頁的php文件中

include_once ("Pagination.php");
//每頁顯示的條數
$pageSize = 10;
//總條目數
$pageTotal = $db->get_var("select count(*) from tb");
//每次顯示的頁數
$sub_pages = 10;
//得到當前是第幾頁
if (is_array($_GET) && count($_GET) > 0) {
	if (isset ($_GET["p"])) { //是否存在"id"的參數
		$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");
