简易分页类
这是一个简单易用的分页类。只需在你原有的程序中加两句、改一句就可以了
先贴代码
paging.php
<?phpclass Paging { public static $count = 0; public static $size = 0; public static $page = 0; static function prepare($sql, $pagesize=10) { $page = isset($_GET['page']) ? $_GET['page'] : 1; $pageon = ($page - 1) * $pagesize; $sql = preg_replace('/select\s/i', '$0SQL_CALC_FOUND_ROWS ', $sql) . " limit $pageon, $pagesize"; $rs = mysql_query($sql); $p = mysql_query('SELECT FOUND_ROWS()'); list(self::$count) = mysql_fetch_row($p); self::$size = $pagesize; self::$page = $page; return $rs; } static function bar($tpl='') { if(!$tpl) $tpl = '<a href=?reset>首页</a> <a href=?prve>上一页</a> <a href=?next>下一页</a> <a href=?end>尾页</a>'; $count = ceil(self::$count / self::$size); $page = self::$page; unset($_GET['page']); $d = array( 'reset' => 1, 'prve' => $page > 1 ? $page - 1 : 1, 'next' => $page < $count ? $page + 1 : $count, 'end' => $count, ); foreach($d as $k=>$v) { $_GET['page'] = $v; $tpl = str_replace($k, http_build_query($_GET), $tpl); } echo $tpl; }}
