expression search

On his blog today Sameer Borate has posted a quick tutorial on how to use a PEAR package to do search and replace on your files from inside of PHP.

OCR combined with a powerful approximate regular expression engine can capture and search data from text on images that would otherwise be lost.

Even in today’s digital age, many companies still rely on paper documents. In order to bridge the gap, Optical Character Recognition (OCR) captures the data on those paper documents and brings that data into the digital workspace.

OCR technology is very useful in a number of different instances and you can create solutions that are even more powerful by adding regular expression search with approximate matching to the OCR technology.
