PHP实现在线阅读PDF文件的方法,

本文实例讲述了PHP实现在线阅读PDF文件的方法。分享给大家供大家参考。具体实现方法如下:

<&#63;php 
if(!function_exists('read_pdf')) { 
 function read_pdf($file) { 
  if(strtolower(substr(strrchr($file,'.'),1)) != 'pdf') { 
   echo '文件格式不对.'; 
   return; 
  } 
  if(!file_exists($file)) { 
   echo '文件不存在'; 
   return; 
  } 
  header('Content-type: application/pdf'); 
  header('filename='.$file); 
  readfile($file); 
 } 
} 
read_pdf('Python_study.pdf');

为了更好地用户体验,建议你前端采用 FlexPaper在线显示文档组件来显示你的文档,先用PDF2SWF工具将你的pdf转成flash文件,然后用 FlexPaper来显示转换后的swf文件,这样用户浏览速度会很快,就像百度文库那样!

<script type="text/javascript" src="pdfobject.js"></script>
<script type="text/javascript" src="jquery-1.8.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){ 

//第一种方式
// var myPDF = new PDFObject({ url: "1.pdf" }).embed(); 

//第二种方式
var variablename = new PDFObject({ url: "1.pdf" }).embed("pdfobj");

//第三种方式
// var myembedparams = {
// url: "1.pdf"
// };
// var myPDF = new PDFObject(myembedparams).embed();
}); 
</script>
</head>
<body>asdfadsfasdf
<div id="pdfobj"></div>
</body>
</html>
