View local website on an Android device

Web developer here. I have two devices, a Samsung Galaxy S3 & a Samsung Note 10.1. I have developed a website which is running on PHP and I would like to view my website on these two devices without having to upload it to an online server. My local server is a WAMPSERVER. I've heard that you could use Wi-Fi and connect to my PC's IP address however my wifi signal is very weak (I use a desktop upstairs, router is downstairs) so I would like a setup that requires me to physically connect my devices to my PC through a USB cable. Is there a way to do this? Thanks in advance! :)
