我不相信有人在PHP中实现了任何OCR解决方案. OCR(光学字符识别)是一个非常复杂的软件，并非任何PHP都适合实现.

I don't believe anybody implemented any OCR solution in PHP. OCR ( Optical Character Recognition ) is a very complex piece of Software and not anything PHP would be suited for to implement.

但是可以肯定的是，您可以从PHP调用外部OCR程序. 因此，您应该寻找可以在命令行中使用的OCR解决方案.

But for sure you can call an external OCR program from PHP. So you should look for an OCR solution which can be used from command line.
