I think that's a bad example you read. It doesn't describe how to
search on a "word" it describes how to search on a string, which is
what you ended up doing.
For things like this I use arrays. Assuming your "words" are separated
by spaces, you can get an array of all the words by doing:
$word_list = explode(' ', $text);

Then you can cycle through each element of the array (there are a
number of ways to do this), testing if it equals your word and replace
it if it does.
Then put it all back together with:
$text = implode(' ', $word_list);
