Reducing the result

[jbachris]

I have a text field for a news story. What I would like to do is call two versions of the field $story. One is the complete $story field, the other is the $story field, but limited to the first 15 words in the $story field.

How can I do this? Thanks!

function TruncateStr($text, $nr_words){
    $tmp = explode(' ', $text, $nr_words);
    $return = '';
    foreach ($tmp as $value) $return.= "{$value} ";
    return $return;
}

This breaks $story into an array, and rejoins the first 15 words with a space between each one:

$short_story="";
$y = explode(" ",$story);
for ($i=0; $i<15 ; $i++) { $short_story .= $y[$i] . " "; }

There is a function for finding the position of the 15th space in a string. Then you could use that position to grab the substring from $story but I can't seem to find that function right now.

Edit: I just read bogu's solution and it's more efficient especially if the story is long.

IMHO you should use strpos() and substr() functions - it will be faster than 2 solutions showed before mine.

NuLL[PL]: And how do u calculate the position where de n words end?

I was wrong - I thought that I cant ignore first space occurences with strpos but its impossible to do this 😉

Sorry for this 🙁
