In Symfony 2 6 and older versions  to get a parameter in a controller - you should get the container first  and then - the needed parameter    this- gt container- gt getParameter  api user      This documentation chapter explains it   While  this- gt get   method in a controller will load a service  doc   In Symfony 2 7 and newer versions  to get a parameter in a controller you can use the following    this- gt getParameter  api user
