This article mainly introduces PHP to implement simple online reading of PDF files. Interested friends can refer to it. I hope it will be helpful to everyone.

The example in this article describes the method of reading PDF files online in PHP. The specific implementation method is as follows:

<?php 
if(!function_exists(&#39;read_pdf&#39;)) { 
 function read_pdf($file) { 
  if(strtolower(substr(strrchr($file,&#39;.&#39;),1)) != &#39;pdf&#39;) { 
   echo &#39;文件格式不对.&#39;; 
   return; 
  } 
  if(!file_exists($file)) { 
   echo &#39;文件不存在&#39;; 
   return; 
  } 
  header(&#39;Content-type: application/pdf&#39;); 
  header(&#39;filename=&#39;.$file); 
  readfile($file); 
 } 
} 
read_pdf(&#39;Python_study.pdf&#39;);

For a better user experience, it is recommended that you use the FlexPaper online display document component to display your front-end For documents, first use the PDF2SWF tool to convert your pdf into a flash file, and then use FlexPaper to display the converted swf file, so that users can browse very quickly, just like Baidu Wenku!
