Compare and merge two word documents using php
<p>I am doing a project on online medical transcription training. For that we are not allowed the original documents to the users.</p>

<p>User must type all the contents he hear and he uploads the documents to the server. Then the Original document will be compared or merged to his edited document and the result file will be downloaded to him to verify. </p>

<p>I need to do this in php? is it possible?</p>

<p>I heard about COM object in php. but i dint find any good example. </p>
