Greetings Lafron,
Thanks for visiting the Apple Support Communities! I understand photos from iCloud Photos aren't appearing on your iPhone, as you mentioned you only see the photos on the PC you have used to upload the photos to iCloud.
I suggest checking the status of your upload to iCloud from iCloud Photos on your PC. Additionally, I suggest visiting iCloud.com to see if you are able to view all of your photos online with iCloud. You can see those steps in the following support article: Get help with iCloud Photos on your Windows PC - Apple Support
Let me know how it goes from here.
Kind regards.
