Yay, Questionnaire time
I love this part of the game
a) I'm not very familiar with regex at all and was wondering if you could
tell me how your regex would handle two matched search strings that
exist within a few words of each other in the text. For example "A
larger server would be sufficient I think".
Answer: As I think I may have mentioned "All I did was conjure up a regular
expression "
True, I didn't imply I wrote that regex in under 32 seconds...But I'm sure I
was trying to come across with the fact that with improvement it could be
much more powerful.
Like this example:
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=were%2Badd&st=post&sb%5B%5D=*&maxres=25&ob=datetime&ot=DESC
Is that better??
multiple words within the same piece of string..
Again, much much much more work can be done, this was a very quick "stub"
example to show the flexibility of regex..
Now a new issue that has been presented is if you DO have multiple words
close together it will only grab x amount of words to the before and after
that central word, including perhaps another keyword.. as you can see on
above link..
Again, give me another 3 minutes in the code and I'm sure I'll work that one
too..
b)Also in the link you provided (reproduced below) the first matched
word is surrounded by 4 words and the second by 5 words, is there a
reason for this?
Answer: Ooh this is my favourite :-) Yes, great reason why when you conduct
a search such as this:
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=sufficient%2Blarge&st=post&sb%5B%5D=*&maxres=25&ob=datetime&ot=DESC
You received the 4 word and 5 word output.. Why don't you head over to the
link that is generated on that search result entry??
Look around at the actual content of that forum entry and you will soon see
that the first match occurs on a line that physically only has 9 words,
therefore it can only really match what exists.
Good point though, for a split second I actually thought to myself there
might be something wrong, but as usual and until I'm proved wrong; I'm right
again. PHP and REGEX have never failed me.
I'm sure you all are well aware already of the saying that describes how
there is no such thing as computer errors, only stupid humans.
And that is precisely it, I have been and still am a stupid human, and I
will usually sit there for quite a while reloading and running a regex in my
head to ensure it runs and parses as it should.
Simple ones like this don't take too much planning, but they can get hairy
:-)
Hopefully that answers your queries Graham..
Kindest Regards to everybody!

All I did was conjure up a regular expression that basically just matches
words :-) haha ironically..
Here it is:
$extract_result="";
preg_match_all("/((?:[\w]+ ?){0,5})[\w
\.\,\-\;]((?:".join("|",$q_arr)."))([\w]*)[\w \.\,\-\;]((?:[\w]+
?){0,5})/i",$row["content"],$ext_matches,PREG_SET_ORDER);
foreach($ext_matches as $ext_arr) {
$extract_result .= $ext_arr[1]." <B>".$ext_arr[2]."</B>".$ext_arr[3]."
".$ext_arr[4]." ... ";
}
Are you familiar with regex?

"An example of a larger post can be found ... we were to add a
sufficient amount of text than we ..."
Thank you.
