title: Permission denied to access the file from php script
body: <p>I have shared library file client.so. Which works fine in command line. I am trying to run it using exec().</p>
  
  <p>client takes one string argument as a input. like ./client "this is nice"
  code is:</p>
  
  <pre><code> $s="hello"; 
   escapeshellarg($s); 
   $a=exec('/home/technoworld/Videos/LinSocket "./client $s"'); 
  </code></pre>
  
  <p>also </p>
  
  <pre><code> $a=exec('/home/technoworld/Videos/LinSocket "./client "Nice bad" "'); 
  </code></pre>
  
  <p>It gives error:</p>
  
  <pre><code>sh: 1: /home/technoworld/Videos/LinSocket: Permission denied
  </code></pre>
  
  <p>I tried changing the chmod all I found on web and other relevant changes. But no change. Any kind of help is highly appreciated!</p>
