To start off, find a used canon 600D or 1100D with a 18-55 kit lens.
Then memorize this - your camera wont make you a better photographer, your skill, your creativity will. A camera is just a tool, how well you can wield it is up to you.
There are tons of tutorials available online, learn about the basics of composition, the ISO, the aperture, depths of field, get to know your camera and how to use it, how to use light and practice. Once you get the hang of basics then practice more till the time you can instinctively change settings on your camera without thinking to take the right shot depending on what you're shooting & how much light is available. When you can do that, then it'll be time for you to get a better camera and some more lenses. Then you won't ask "which is best camera" or "which is best dslr". Rather you'd know what you want from a camera and you would ask for opinions about the technicalities of different camera models to decide which one you should consider!
