Im looking at getting a controller for these (WS2812B) Led strips and i want to be able to connect it to my phone. I want the controller to be able to control 25m (80ft) of led strips. I dont know if i will need two controllers or not. and if so, am I able to connect those controllers together to work in sync. I also want to be able to us an IR remote and was wondering if that remote can control multiple controllers. I just dont know the difference between the different ones i just know i dont kneed the one with microphone.

For 25m of WS2812B, you’ll likely need power injection and possibly two WLED controllers, synced via UDP. An ESP32-based board with an IR receiver fits your phone + remote needs. Also check data limits per pin (e.g., around 500–800 LEDs) to decide on splitting runs. This post on Crazy Cattle 3D has a clear primer: Crazy Cattle 3D. It helped me plan wiring, power supplies, and IR control across multiple controllers.
