Did you maybe move this code here without moving the variable definition? This error can happen if you refactor code and forget to move the variable initialization. Let’s take a look at a simple example: function someFunction() { $x = 5; echo $x; } The above code is perfectly fine. Now imagine that we re-order the statements: function someFunction() { echo $x; $x = 5; } In that case, `$x` would be read before it is initialized.
