Regexp - How to match all words except strict ones?

Question

I'm trying to find a regexp that exclude specific word but not words containing it.

For example if we exclude the word "home"

home --> NOT OK
homefree -> OK
freehome -> OK

Any ideas ?

Thanks

I would recommend taking a look at Rexegg — Word Boundaries .

If you want to match lines not containing "home" itself, you can do:

preg_match_all('/^(?!.*\bhome\b).*$/im', $str, $matches);

If you want to match the words alone:

preg_match_all('/\b(?!home\b)\w+/i', $str, $matches);
