taking words from a file

[ucbones]

I am attempting to parse the contents of a file to place them into the database. For some reason, however, it is returning each word twice, any ideas? Try it, separating words by spaces, each returns it twice. This script is actually a version of Dan Solin's search engine script, which places words from a file in a DB. But it returns each word twice, haven't got a clue what's wrong (not too good with multi-dimensional arrays...)

Many thanks,

took too long to reply 😉 bit of trial and error and I fixed it myself, change $i++ to $i=$i+2, not really sure why it printed each word twice, but doesn't now... any ideas why? If not no worries, problem solved, just intellectual curiosity
