Ok, My example was pretty bad.
I was just looking for an easier/more optimal way to look for something
along the lines of
"word1*word2*word3*word4" rather than "word1 word2 word3 word4" as it
currently does.
Actually, I think I have an idea for a way to do what I want without a
regular expression.... I'll have to see how fast it is though before
actually using it.
Not guaranteed to work at all but if you really want to use a regex you
could do something like this:
$words = array('word1', 'word2', 'word3');
$search = '%';
foreach ($words as $word) {
$search .= '\\\b'.preg_quote($word, '%') . '\\\b.*?';
}
$search .= '%is';
preg_match($search, $string, $found_matches);
So you should end up with something like:
preg_match('%\bword1\b.*?\bword2\b.*?\bword3\b%is', $string,
$found_matches);
