Replacement possible

Environment::scriptName()

       string(2) "en"
     }
Request::getLanguages()          
  => array(4) {
       [0] =>
       string(5) "de_DE"
       [1] =>
       string(2) "de"
       [2] =>
       string(5) "en_US"
       [3] =>
       string(2) "en"
     }

Environment::httpAcceptEncoding()
  => array(3) {
       [0] =>
       string(4) "gzip"
       [1] =>
       string(7) "deflate"

Environment::httpUserAgent()

Request::$headers->get('user-agent')

Environment::httpHost()
  => string(9) "localhost"
Request::getHttpHost() 
  => string(9) "localhost"

Environment::ssl() 
  => bool(false)
Request::isSecure()

Environment::url()

  => string(9) "localhost"
Request::getHttpHost()
  => string(9) "localhost"

Environment::isAjaxRequest()
  => bool(false)
Request::isXmlHttpRequest() 
  => bool(false)

Replacement may not return same result

The documentation of Request::getHost() says, that it use the X-Forward-Host header, if it's trusted. But I cannot get it work :-\

Environment::httpXForwardedHost()
  => string(17) "local.localdomain"
Request::getHost()               
  => string(9) "localhost"

Replacement imo not necessary

These methods are not necessary imo, urls should be buildet with the url builder / router.

Environment::path()   
  => string(23) "/environment-vs-request"
Request::getBasePath()
  => string(23) "/environment-vs-request"

Environment::base()                                                             
  => string(40) "http://localhost/environment-vs-request/"
Request::getScheme() . '://' . Request::getHost() . Request::getBasePath() . '/'
  => string(40) "http://localhost/environment-vs-request/"

Environment::scriptFilename()
  => string(58) "/home/tristan/public_html/environment-vs-request/index.php"

Environment::script()
  => string(9) "index.php"

Environment::request()
  => string(24) "some/path?with=arguments"

Environment::indexFreeRequest()
  => string(24) "some/path?with=arguments"

Replacement impossible (alternative required)

Environment::agent()
  => string(3) "..."
