Show first x number of words or a comment....

I hope I asked that correctly.

On my site... www.shareyourexpertise.com I have a comment tab (on main page) . In the back there is a paramater to to show the number of letters to display of the comment (it is a db field).

Is there a php command I can use to I can tell it to show I certain number of words not letters?

 

Something like this?

<?php

function fetch_words($text, $words = 10)
{
	$chunk = array_chunk(preg_split('/\s+/', $text), $words);
	return implode(' ', $chunk[0]);
}

$text = 'this is a stupid text blah blah blah';

echo fetch_words($text, 5);

?>

PHP:

 

but how would i pull it from the database and make it display only a certian number of words.....sorry i am new to this......

so say the database filed contained


"Harry met Sally on the road to Melbourne"

and I wanted to display only 3 words or how many I choose....thanks1

 

Pull the whole text from the database and use the function on variable.

I can't post the exact code you need cause I haven't seen your's. But it's something like this.

$text = 'Harry met Sally on the road to Melbourne';

echo fetch_words($text, 5);

PHP:

With 5 being the number of words you want to display.
