Help with substr()

[benji87]

Hi all ive currently got some news displaying which i have limited to 75 characters using the substr() function so the user can click and read more. Im just wondering if there is a way to get the script to not chop off the end of words. As every bit of news will be different lengths there is no garuntee that it will show whole words when it comes to the end of the string of 75 charcs.

For example if i have news with the first sentance being displayed i want it to show like this:

This is the first sentance of this news article.

and not this:

This is the first sentance of this ne

Can anyone help?

that should do :-)
[code]
<?
function filter_wordlimit($string, $length = 50, $ellipsis = '...'){
return count($words = preg_split('/\s+/', ltrim($string), $length + 1)) > $length ? rtrim(substr($string, 0, strlen($string) - strlen(end($words)))) . $ellipsis : $string;
}
?>
[/code]

Take a look at [url=http://www.php.net/wordwrap]wordwrap()[/url] and use it together with [url=http://www.php.net/explode]explode()[/url]

ex:
[code=php:0]$string = 'Hi all ive currently got some news displaying which i have limited to 75 characters using the substr() function so the user can click and read more.';

$string = wordwrap($string, 75, "|", 1);
list($string) = explode('|', $string);

echo $string;[/code]
