VSCode 1.89.1 PHP Extension 1.47.15561 (pre-release)

The PHP extension does not check for the use of string operators on undeclared variables as an error

Thank you for the suggestion. You are right, in the case of .= operator, we silenced the warning because there were too many such cases in various legacy PHP frameworks. The regular string concatenation operator . gives the warning.

I think we can stop silencing the warning for the .= operator.
