If you go this route, perhaps you could enclose each member of your
original array in \b word boundary sequences using an array_walk
routine so that you don't have to muddy your original array
declaration statement.

You're absolutely right -- I was focusing so much on the regexp
syntax that I failed to broaden my gaze...
When the OP corrects his PHP to use preg_replace() instead of
str_replace(), I believe he'll still need to provide word boundaries
around each member of his noise-word array, otherwise the function
will simply remove all letters and digits from the words in the
search-string he considers meaningful and he'll end up searching thin air.
Aside, without knowing the context of his search, it seems a bit
extreme to remove all single characters from the search string. It's
not hard to think of examples of them occurring as part of valid
entity names in our universe -- she got an A, Plan B From Outer
Space, Vitamin C, etc.
An alternative strategy might be to trust the user to enter a valid
search string and simply warn them that the quality of the answer
they get will depend on the quality of their input.
