Breaking up an article

How to break up a string for  example $row['asdasdasd']
when it has more than 300 chars show the first 300 and display more... at the end.

if(strlen($text) > 300){
$text
}

I have that for now.... from here???

<?
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;
}
?>

Nice, but can i have a little explanation on the code, please?

[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;
}

echo filter_wordlimit('I can put a really long paragraph in here if i want to, and it will trim it down to 20 words long','20');
?>
[/code]

feri_soft doesnt want to know how to use the function, but how the code works.

oh... ok :-) basically... it counts how many words are in, the string, if its not greater then the $length, it returns it as is, if it is greater, it cuts off after the last allowed word and adds "..." and returns that.

It is working now, but actually i wanted something to count the chars not the individual words, something with strlen maybe...

[code]<?
function filter_charlimit($string, $length="50"){
if(strlen($string)<$length) return $string;
else return trim(substr($string, 0, $length)).'...';
}
?>[/code]

there ya go... that one counts chars, not words :-)
