general code style fixes (#1241) 

* use instanceof instead of is_a

is_a is deprecated since 5.0.0 in favour of instanceof operator
http://php.net/is_a

this allows using class aliases instead of strings

* do not assign null to class properties

that is default behaviour of php engine

* use stripos instead of stristr

* use faster $array[]= $value instead of array_push

* add SuspiciousAssignmentsInspection noinspection to shut up ide

* use call_user_func with defined args

* avoid overwriting $error parameter

* apply more yoda-style
