php对文本文件进行分页功能简单实现
<!DOCTYPE><html><head> <meta http-equiv="Content-type" content="text/html";charset="gb2312"> <title>Paging</title> <style> a{ padding:20px; } </style></head><body><?php// 中文字符处理function m_substr($str, $start, $length){ $str_length = $start + $length; // 获取截取总长度 $tmp_str = ""; for($i=0;$i<$str_length;$i++){ if(ord(substr($str, $i, 1)) == 0x0a){ $tmp_str .= "<br>"; } if(ord(substr($str, $i, 1))>0xa0){ $tmp_str .= substr($str, $i, 2); $i++; }else{ $tmp_str .= substr($str, $i, 1); } } return $tmp_str;}// 传参处理if(isset($_GET['page'])){ $page = $_GET['page'];}else{ $page = 1;}$counter = file_get_contents("example.txt");$length = strlen($counter);$page_count = ceil($length/400);$pre_str = m_substr($counter, 0, ($page-1)*400);$now_str = m_substr($counter, 0, $page*400);echo substr($now_str, strlen($pre_str), strlen($now_str)-strlen($pre_str));echo "<br><br>";echo "当前页".$page."/".$page_count;echo "<a href='index.php?page=1'>Index</a>";if($page>1){ echo "<a href='index.php?page=".($page-1)."'>Pre</a>";}if($page<$page_count){ echo "<a href=index.php?page=".($page+1).">Next</a>";}echo "<a href=index.php?page=$page_count>End</a>";?></body></html>
