I'm writing a few very simple search scripts.
One searches in a few columns of a CSV file, while another just searches
through a collection of file names.
Currently, I just have it stripping illegal characters from the "needle"
and "haystack" then doing a substring search
if (substr_count(...)>0) {
return formatted results....
}
What I'm looking to do is enhance my searches with preg_match. What I
want to do is take my needle and haystack with the illegal strings
stripped out, split it down to words, and search for the string, no
matter what is between the words.
ex: "the cat and the dog"
would also return
"the cat ran from the bull and dog"
I might learn Regular Expressions at some point in the future, but I
just haven't had time to yet... so what I need is just what I would use
to build my string pattern for preg_match... I'll figure out the rest
and change my scripts appropriately.
You're not going to be able to do that with a regular expression because
the order of the words isn't even the same.
Why would you need to do this with a regex instead of the way it's
working right now?
