php - How to check if the server is in production or development environment? -

-

i refer this question regarding checking of server's environment php. why remote_addr being used instead of server_addr when checking whether server in production environment or development environment? sorry, confused here because thought remote_addr refers client's ip address. better use server_addr or there other reason why remote_addr chosen?

  • the server_addr returns ip address of server under current script executing.
  • the remote_addr returns ip address user viewing current page.

you should read manual.

assume below script running on server..

<?php echo $_server['server_addr']; echo $_server['remote_addr'];

the first line prints server's ip address (this not change unless move script other server). second line prints ip address of user viewing page.(this changing different users connected different pcs)
