It's not so much impossible to perform OCR as it is unrealistic to do
so. PHP contains only the very most basic support for such things, not
to mention there are barely any (OS) libraries for PHP to do this, it's
simply not realistic to try and make one if you're "on your own". Other
languages (ie. C) have libraries, written by people specifically for
this purpose, so it seems clear to me: PHP is (currently) not the most
realistic language to try and do OCR with, instead it'd be a lot easier
(at this point) to "borrow" from another. Be this a low-level library in
C, or a full-blown package, it doesn't matter.
Take the library of a C OCR program, write some PHP C code around it
and a new extension is born :)
