php question

Hi
Im messing with php here for a site. What i want to do is display the first hundred characters of a certain db field if its greater than 100 character and then display ... (which i can do no probs)
However if there is a word present at character 100 it will cut it up. how can i stop this and make sure the ... appears after a word?

Thank you

I put together a PHP function that should do what you are looking for. I just wrote it now and didn't really test it so you may have to tweak it a bit. It should return all the full words within the first 100 characters.

[php]<?php
$string = "This is a string which I want to cut at 100 characters. However, I want it to display a full word at the end and not just part of the word.";
$cut_off_point = 100;
$string_length = strlen($string);

function SplitString($string, $cut_off=100) {
if(is_numeric($cut_off)) {
if(strlen($string)>$cut_off) {
$words = preg_split("/\s+/", $string);
$string = "";
$pos = 0;
do {
$string .= $words[$pos]." ";
$pos++;
} while (strlen($string)<$cut_off);
$string = rtrim($string, " ");
}
}
return $string;
}

$string = SplitString($string);
print $string."...";
?>
[/php]

Edit: There's some weirdness with the str_word_count() function - it treats numbers as white space. Swapped it for RegEx.
