I doubt very much that there's a native library in PHP for this sort of thing. It's not exactly the language of choice for complex image recognition.

You can call external programs in PHP with exec(), system(), passthru(), popen() and proc_open(). Read here about how they work and what the differences are. You can then use Canny or other software of choice with their usual command line usage.
