title: install FFMPEG on PHP 7.0.6 - Xampp
body: <p>I am new to php. I am trying to convert video uploaded by the user.
  Somehow, I have done all the php work except conversion. I came to know about <strong>FFMPEG</strong>, I have installed it and tried with CLI and it worked perfect.</p>
  
  <p>When I tried it in ph using <strong>shell_exec()</strong> command. It gives me nothing, Then by google, I should activate the extension of ffmpeg in my php.ini file.</p>
  
  <pre><code>shell_exec("ffmpeg -i video/Wildlife.wmv video/output.mp4");
  </code></pre>
  
  <p>I have googled but there is no help regarding this php version.
  Any idea or guideline will be very helpful.</p>
  
  <p>This may be a duplicate question but there is nothing with php 7 version on stackoverflow.</p>
