This error can happen if you refactor code and forget to move the variable initialization.
Let’s take a look at a simple example:
The above code is perfectly fine. Now imagine that we re-order the statements:
In that case,
$xwould be read before it is initialized. This was a very basic example, however the principle is the same for the found issue.
