Greetings King of RegEx-Obfuscation! ;-)

What would be the average length of $word for 1 million entries? 10 MB?

Cheers Rolf

==== Update

you can improve preformance if you sort by number of whitespaces first and only add to $word in chunks of strings with the same number of whitespaces.

There is no point searching in an n word string being included in another n-word string.

Particularly you can stop searching once you reached the one word strings.
