# Need advice about functions.php

 * so I added a piece of code to functions.php due to a functionality that I want
   to include in the website using WP file manager. The entire website crashed immediately
   after I saved the code and another team who’s responsible for restoring the backup
   had to come in and save the day. 
   I don’t want to repeat this mistake. In the
   past I have added code to the php several times but never such a thing happened.
   So what should I do to prevent it and be able to add code without disturbing 
   the website. Is there a way to test the code without actually saving it in wp
   file manager?Also what could have gone wrong with the code I added that the entire
   website crashed? Any insight will be highly appreciated.

 * My recommendation would be to test the code you want to insert in a test system
   first. This can also be a staging system, for example, i.e. a copy of the live
   website. Your host can provide you with this if necessary.
 * It is also helpful to test code in a programming IDE (Visual Code, phpstorm).
   Or at least in an editor that points out syntax errors (Notepad++ with appropriate
   add-ons). A forgotten comma or bracket can lead to what you have experienced.
   Such an editor will visually point this out to you. I think there is also something
   like this available online in the browser.
 * If you show the code you have inserted, they might be able to tell you what is
   wrong with it.
