PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

     * @param boolean $strict
     *
     * @return void

Adding a @return annotation to constructors is generally not recommended as a constructor does not have a meaningful return value.

The call to mysqli_strict::__construct() has too many arguments starting with $main['host'].
