Wp-Config is one of the most important files in WordPress, the first being the htaccess file. These files, although lightweight and with just a couple lines of code, have a lot more power and importance as compared to all the other WordPress files you’ve got.

So before getting into the “how’ of the topic, let me get into the “why” of it.

I mean why do you even need to edit the wp-config file, right? What’s the need, is it even worth considering? To answer all of that, let me scribble down a dedicated section for it.

Why wp-config.php File in WordPress?

So as I’ve said, the wp-config file is important, but why? What’s the importance of it?

  1. Well, in case you don’t know, WordPress has lots of Usernames and passwords and connection permissions and stuff like that. Yeah, on the surface level you have just your login Id and Password, but on the root level, there’s Database login, database connection details, HOST values, and stuff like that.
  2. In case you’re a debugger, you can set the “wp debug” mode to TRUE to enable the WordPress debugging mode from the Wp-config.php file
  3. Override Subdirectory database calls.
  4. Override File Permissions. There are times when you need to overcome the restrictions imposed on you even if you’re the Administrator, and that you can do via the wp-config.php file.
  5. Modify Auto-Save Configuration! There’s that feature that saves our posts every 60 seconds automatically, right? You can increase or decrease that time frame from the wp-config file!
  6. Ever faced the very common “WordPress Memory Exhausted” error while browsing your website? Well, you can increase the PHP memory using the wp-config.php file to overcome this error.
  7. Change/Modify Database Pre-fix. Well the default database prefix for WordPress is “wp_”, which is known to every soul out there, so having it as the prefix isn’t the best security measure for your website, and that’s again something you can edit and change from your wp-config file!

So yeah those are just some of the things you can do from the wp-config.php file! Hence I think it’s importance is not a matter of doubt anymore, is it?

So let me just say that, just like Functions.php is the most important file for your WordPress theme, similarly wp-config.php is definitely the supreme ruler of the whole of your WordPress installation.
