PHP简单分页函数
function getask(){ $sql = "select * from cms_ask where ansower <> ' ' "; //这里要改成方法 $q_sq = mysql_query($sql); $count = mysql_num_rows($q_sq); $page_size = 8; $page_current = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1; $page_count = ceil($count / $page_size); $page_start = $page_current - 4; $page_end = $page_current + 4; if ($page_current < 5) { $page_start = 1; $page_end = 5; } if ($page_current > $page_count - 4) { $page_start = $page_count - 8; $page_end = $page_count; } if ($page_start < 1) $page_start = 1; if ($page_end > $page_count) $page_end = $page_count; $pagebar = ""; $sql = "select * from cms_ask where ansower <> ' ' order by id desc limit " . (($page_current - 1) * $page_size) . "," . $page_size; $row=$this -> user -> getall("$sql"); foreach($row as $v){ echo '问:'.$v["question"].'答:'.$v["ansower"].date("Y-m-d H:i:s",$v["postTime"]).''; } $pagebar .= ""; $pagebar .= ""; if ($page_current != 1) { $pagebar .= 'FIRST'; } for ($i = $page_start; $i <= $page_end; $i++) { if ($i == $page_current) { $pagebar .= "" . $i . ""; } else { $pagebar .= "" . $i . ""; } } if ($page_current != $page_count) { $pagebar .= "END"; } $pagebar .= ""; $pagebar .= ""; echo $pagebar; }
