Localhost / live - discovery by HTTP_HOST

Question

let's say I develop locally and debug small things on a real server.

Is it good to have something like this in my code?

$is_local = (strpos($_SERVER['HTTP_HOST'], 'localhost') !== false);
define ('DEBUG',$is_local);

And then use it through your code when setting up?

$mysql_settings = (DEBUG) ? 
  array(/*localhost settings*/) : 
  array(/*live settings*/);

Thus, I can use the same files live and on the local host, so I can synchronize without fear of error, for example. connection settings on a real server.

Is this a good or wrong idea?

Answer 1

Nothing wrong with the way you do it.

Another strategy is to set some environment variable for your development (or other, non-production) system.

Under apache, you can insert something like this:

SetEnv MYAPP_ENVIRONMENT development

httpd.conf .htaccess

:

if (! getenv('MYAPP_ENVIRONMENT')){
  $env = 'production';
}else{
  $env = getenv('MYAPP_ENVIRONMENT"));
}

require_once 'conf/config.' . $env . '.php';
