PHP 讀取文字檔內容並分頁顯示_php執行個體

功能很簡單，只是使用 PHP 讀取文本(TXT)檔案 並分頁顯示

<?php //----------------you should save this file as m.php----------------  session_start();   if (empty($page)) {$page=1;}  if (isset($_GET['page'])==TRUE) {$page=$_GET['page']; }?>    Read Result    
 
 
  

   
 
    
 <?php if($page){ $counter=file_get_contents("example.txt"); //-------read the file into a string.-------$length=strlen($counter); $page_count=ceil($length/5000); function msubstr($str,$start,$len){ $strlength=$start+$len; $tmpstr=""; for($i=0;$i<$strlength;$i++) { if(ord(substr($str,$i,1))==0x0a) { $tmpstr.='
'; } if(ord(substr($str,$i,1))>0xa0) { $tmpstr.=substr($str,$i,2); $i++; } else{ $tmpstr.=substr($str,$i,1); } } return $tmpstr; } //--------------------------截取中文字串-------------------------- $c=msubstr($counter,0,($page-1)*5000); $c1=msubstr($counter,0,$page*5000); echo substr($c1,strlen($c),strlen($c1)-strlen($c)); }?> 
 
   
 
  
 
  
 
 
  

   
 
    
 <?php echo $page;?> / <?php echo $page_count;?> 頁 
 
    
<?phpecho "首頁 "; if($page!=1){ echo "上一頁 "; } if($page<$page_count){ echo "下一頁 "; }echo "尾頁"; ?>
