[thelist] Text Comparison

[Peter Brunone (EasyListBox.com)]

		   I'm not even sure I understand the requirement.  Users are going to enter sentences without spaces and you're going to split them up into their component words?  That doesn't make sense, so I'm pretty sure I don't get it.

   What's the final goal here?

I have a potential new project--a text comparison engine. The input will 
be various versions of texts such as this:

1 To be or not to be that is the question.
2 To or not that's the question.
3 To been or to bend is the question.

The job of the algorithm is to accept input such as that, but of course 
without the added spaces, and to basically just add the spaces. The 
system will need to compare all the inputted texts (more than 3 in 
reality) and find the matching words and print out all the texts in a 
structure something like the above. No one text will be defined as the 
authoritative--all texts must be compared and aligned as shown.

The task requirements are not actually specifically for a website, but 
since that's what I have been coding for the past few years, that seems 
the easiest approach for me.

Is anyone aware of any existing PHP tools that would help with such a task?

Any other suggestions/advice are appreciated. :)

Thank you,
Hershel
