RE: [PHP] splitting text solved
i found a snippet somewhere which helped me out and i modified it
?
$input= and a phrase \escaping text\ \howard sux\;
if (preg_match_all('/(?:((?:\\\.|[^\\\])*?)|\b([\S]+)\b)/', $input,
$match)) {
foreach ($match[0] as $key=$value) {
$keyword .= +.$value;
}
}
echo $keyword;
?
so basically u can have a heap of keywords with some in exact phrases within
quotes and it adds the + for you to make it an AND boolean search string for
mysql full text :D

Subject: [PHP] splitting text
hi there , i am building a fulltext search engine which will use the mysql
boolean search features , although it defaults to OR with words between
spaces you have to explictly put a + in front of words so say i typed
some word word2 ,to get both i have to do +some word +word2
how can i split this phrase some word word2 so that i can split some
word and word2 into two different words so i can format them , currently
split on a space will split some word into some and word any ideas ?

RE: [PHP] splitting text after 25 words
For future reference using explode and counting the words is not the correct
way to do this. Your array could be huge, and if you have multiple requests
to the page this would be a horrible idea. I believe the correct way to do
this is to use MySQL inherent function SUBSTRING_INDEX(str,delim,count)
So for example:
SELECT SUBSTRING_INDEX(column_name, ' ', 20) FROM table_name
would return the first 20 words. The php way is over-doing it. If you can
perform the logic in your mysql query, you should.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
From MySQL manual:
http://www.mysql.com/doc/S/t/String_functions.html
SUBSTRING_INDEX(str,delim,count)
Returns the substring from string str before count occurrences of the
delimiter delim. If count is positive, everything to the left of the final
delimiter (counting from the left) is returned. If count is negative,
everything to the right of the final delimiter (counting from the right) is
returned:
mysql select SUBSTRING_INDEX('www.mysql.com', '.', 2);
- 'www.mysql'
mysql select SUBSTRING_INDEX('www.mysql.com', '.', -2);
- 'mysql.com'
This function is multi-byte safe.

someting i've used.

$teaser = $teaser . . $storywords[$i];
}
?
? echo $teaser...;?

Hi all,
I'd like to split a text block at 25 words, as a teaser for the full
article. Now I know how to split at a certain character, but i don't
want a half word or anything, so I want (i guess) to hunt for the 25th
occurence of (a space), and split $text into two new variables,
$text_a and $text_b.
Then I'll prolly want append something like ... click here to read
more on the end of $text_a.
Seems easy enough, but I can't see anything in the manual about
splitting on a numbered occurence of a string (but I could be looking
in the wrong spot :)
Running PHP4 BTW
Thanks heaps in advance

Re: [PHP] splitting text after 25 words
Hi, Best way i guess would be traverse the whole string and check for space. Have a counter var which keeps count of the space. At the 25th occurence do something like this - $text_a = substr($text, 1, $i); i assume that $i is the increment var in the loop. $text_b = substr($text, $i+1); This should give u the strings in 2 vars. Now u can add anything with $text_aClick here .$text_b Hope i was helpful, Karthik. - Original Message - From: Justin French [EMAIL PROTECTED] To: php [EMAIL PROTECTED] Sent: Wednesday, August 08, 2001 10:27 AM Subject: [PHP] splitting text after 25 words Hi all, I'd like to split a text block at 25 words, as a teaser for the full article.

RE: [PHP] Splitting Text
Jord, I would accomplish this through SQL. You could use SELECT LEFT(mycolumn,x) FROM mytable WHERE ... and then display that along with a link to a page where you select the whole string on that particular article ID. In fact, I do this exact thing on my site. Or you could read the whole string into an array, and use the PHP function to retrieve the substring you want. I prefer the first option however.
