Hi,
I am sorry if this problem is too easy but I just can't figure out a way to
do this.
I am making a search engine and I would have the user to type a sentence to
search for.
Let's say it is stored in $search.
My search enginue will bring up a result IF and only if ALL of the words in
$search exist in the result. For example
if
$search = Vax Useful Commands
Then the result is only true if (eregi(".*Vax.*Useful.*Commands.*",
'possible result')) is true
Now, I don't know how many words there are in $search initially. How do I
do a search like that? I mean if I know $search is 3 words then I can do
$words = preg_split("/ /", $search);
if (eregi(".*words[0].*words[1].*words[2].*", 'possible result')) {
.....
}
Even if I know how many words there are, everytime the number of words in
$search can be different.
Can anybody give me any ideas?
Thanks a lot
Kelvin
