.txt文件未使用PHP的文件I / O方法显示在Bootstrap模式下

Question

My current issue is that when a link is clicked in a table, the modal that gets triggered does not display a .txt file given in the PHP code. The PHP statement is nested in the HTML <p> and <pre> paragraph statement and uses the fopen and fread methods. The code, once executed, only shows an empty box.

<div id=<?php echo "$id"; ?> class="modal fade" aria-hidden="true"   style="display: none;">
 <div class="modal-dialog">
   <div class="modal-content">
     <div class="modal-header"><button aria-hidden="true" class="close"data-dismiss="modal" type="button">×</button>

         <h4 class="modal-title"><?php echo "$first_name $last_name"; ?></h4>
           </div>

    <div class="modal-body"><img src="empty_profile.gif" width="200px" height="200px" alt="Pic goes here"><br>
    <a href="mail goes here" target="_blank"><i class="fa fa-envelope"></i>&nbsp; Mail</a>    
     <p>
      <pre>
        <?php
          $file = fopen("358.txt", "r") or die("txt not found!!1");
          $read=fread($file);
          echo "$read";
          fclose($file);?> 
      </pre>    
    </p>    
   </div>

The best place for the PHP file i/o, in my opinion, is inside the "modal-body" class div, as the format structure of the modal would only allow for it to be right after the header. How can I get the file contents to show in my modal?

Answer 1

You're using fread incorrectly (you're missing the length argument).

Instead, do as the documentation suggests and use file_get_contents instead...

Note :
If you just want to get the contents of a file into a string, use file_get_contents() as it has much better performance than the code above.

For example

<pre>
  <?= is_readable('358.txt') ? file_get_contents('358.txt') : 'txt not found!!1' ?>
</pre>
