print the first 250 characters of a paragraph

BabeWalls

I have a paragraph which is a description of a product.

I want to display the first 250 characters of the paragraph and then have a "More" link which the user can click to read the rest of the paragraph.

How do I do this?

Any help is appreciated.
Thanks

Hi,
there is many solution.

Any can be this:
Put all char in a string (this will put it on mem but will not submit to client...).
Then use substr() function to show paragraph of 250 chars.

for more help www.php.net/substr

Another way is to use dhtml, with <DIV STYLE="visibility: hidden;" > tag. But there isn't a standard, and you have to submit however all chars to client.

see you

I don't understand.

Could you please give an example of the code which I would need to place into my page?

Ok:

<P><?
if(!isset($page))$page=0;

$myusefullandlongtext="<put your text, all chars, even more than 250>";
// You can also load it from file:
// $myusefullandlongtext=readfile("name_of_file");

echo substr($myusefullandlongtext,$page*250,($page+1)*250);
?></p>
<a href="<?=$SELF_PHP?>?page=<?=($page+1)?>">..more&gt;&gt; </a>

I hope this make sense...

Go read the manual on substr()

$shortened_string = substr ($original_string, 0, 250);

Great stuff bad76. Works perfectly.

I read that page which you pointed me to but none of it made very much sense to me.

Thanks again.
