PHP has a number of functions - as shown by Pritaeas' link, but you need to set rules for the comparison, as it can get quite complicated. Case sensitive - OK. How would you do the following:

"Hello World Says Me" | "I Said Hello My World Hello"

What sort of %age would you return for this with your rules?
