Question

I recently changed pcs and transferred a site I was working on from one pc to the other (including database).

When loading my site in the new pc, I encounter this error:

Notice: Use of undefined constant
Notice: Undefined index:

I did some research and found it can be solved by adding this to my code:

<?php error_reporting (E_ALL ^ E_NOTICE); ?>

Is this something good to do? Or should I change my code more?

Answer 1

It is most likely different PHP settings. The computer you are now testing on has notices turned on. In your php.ini file search for the text “error_reporting” and change it to E_ALL & ~E_NOTICE if you don’t want to see notices.

But it is best to keep notices on in your development environment
