title: Executing PHP shell command requires sudo access
body: <p>I have written PHP code to execute shell command</p>
  
  <pre><code>&lt;?php exec("phing"); ?&gt;
  </code></pre>
  
  <p>This is not working at all from <strong>browser</strong>. </p>
  
  <p>But what I analysed is, it running same command requires "sudo" permission. I am not sure how could I allow my PHP file to execute this commnand as sudo?</p>
  
  <p>Please guide</p>
