i found a snippet somewhere which helped me out and i modified it
$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
someting i've used.

This function is multi-byte safe.

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
$teaser = explode(" ", $article, 26));
array_pop($teaser);
$teaser = implode(" ", $teaser);

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,cou
Thanks for that. I ended up using your method as using the LEFT function in a
SELECT only grabs characters.

You can do this several ways... Either use explode():
http://www.php.net/manual/en/function.explode.php
...to split the retrieved data by a space " " as the delimeter, then use
a for() loop to print X number of words... E.g.:
$array = explode(" ", $db_string);
for($i = 0; $i < 25; $i++)
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 strin
