title: Difference between $_SERVER and $_ENV
body: <p>Is my understand regarding superglobal arrays $_ENV and $_SERVER correct ?</p>
  
  <blockquote>
    <p>$_ENV: Contains information about environment variables <br />
    $_SERVER:
    Contains information about the server</p>
    
    <p>$_ENV is accessible from both web server and on the command line <br />
    $_SERVER is accessible through only web server, not on the command line</p>
