Fix phpcs errors and warnings

Kindly review patch.

@Arti, please look at the screenshot attached. My phpcs error log is very much different from yours.
Also when I applied your patch it doesn't work. I have applied the patch through composer. The patch is failing.
Please re-look into it. And Thank you.
