Conversion of Images into Text using PHP

[dream2rule]

Hello All,

I would need a script(if any) or ideas on how to go about in converting any type of an image file into a text document.

More Specifically:
The tasks can be even divided like

(1) Firstly, converting the image file into a PDF document and then

(2) The PDF document needs to be converted to a text file.

The IMAGE FILE being a Tiff image i.e, scanned copy of a text document.

Is there anyway where i would be able to convert a tiff image into a text file?

Is this possible using PHP?

Thanks & Regards,

Yes but i am unable to figure it out.
Have you got any idea of using Optical Character Recognition in PHP. The logic behind it and so on...

That would be a great help as i have just started coding in PHP and this is one of the important and difficult tasks i have ever come across.

I would want to succeed in this anyways.

Hope this forum would help me in achieving this.

Thanks and Regards
