Reproducibility: Happens every time

STEPS:
  * I'm coding a project in PHP 5.6.27
  * I want to override the method begin_transaction of the parent class mysqli
  * I start to write "public function be".. and the autocompletion window popup suggesting me
     the syntax to override begin_transaction of mysqli.
  * I accept the suggestion
  * After the suggested code is included in the class, the Editor underline it like an error saying that
      the feature is not compatible with the PHP version used in the project
  * Carefully looking, I get that the the suggested code is PHP 7 code (including the types in the method
     signature). 

ACTUAL:
  the suggested code for the method overriding is PHP 7 code 

EXPECTED:
  the suggested code for the method overriding should be of the version used in the project
