title: PHP 5.4.28 giving bad header for bad header for simple phpinfo script
body: <p>There was a memcache installation that went bad.
  And now the <strong>index.php</strong> which only has below code gives malformed header !</p>
  
  <pre><code>&lt;?php phpinfo(); ?&gt;
  </code></pre>
  
  <p>Error:<br>
  <strong><em>malformed header from script. Bad header=phpinfo(): index.php</em></strong></p>
  
  <p>The reason I think it's 5.4.28 version is because that's what php -v shows.
  I've read on other forums that, it might not be the actual php version.</p>
  
  <p>I'm worried if my php installation is corrupted, hence wanted to run the above to just see if it worked.</p>
  
  <p>Any pointers on what might be wrong ?</p>
  
  <p><strong>More info</strong></p>
  
  <ul>
  <li>PHP module : To see which php modules are loaded, I ran <em>httpd -M</em>, out of the 60 modules loaded, this one had php in it: <strong>suphp_module (shared)</strong></li>
  <li>OS is <strong><em>CentOS 6.9</em></strong></li>
