Help with PHP shorten text function

steveland?

Hey,
I have a function I use in PHP to shorten a string of text.

function ShortenText($text) {

        $chars = 50;

        $text = $text." ";
        $text = substr($text,0,$chars);
        $text = substr($text,0,strrpos($text,' '));
        $text = $text."[...]";

        return $text;

    }

What I was wondering is is it possible to change the last line ($text = $text."[...]"; ) so that it incorporates maybe an if statement so that if it's shorter than the 50 characters it won't display the [...]?

It'd be something along the lines of

function ShortenText($text) {

        // Change to the number of characters you want to display
        $chars = 50;

        $text = $text." ";
        $text = substr($text,0,$chars);
        $text = substr($text,0,strrpos($text,' '));
  
        if($text = longer_than($chars))
              $text = $text."[...]";

        return $text;

    }

or something along those lines.

Any help would be appreciated. I'm using it to shorten the title of a forum on a phpBB board for an RSS feed

if (strlen($text) >= 50)
     $text = $text."[...]";

Hope this helps :v:

Cheers mate, managed to edit that around a little to negate the need to use the function at all if the text is shorter than the limit :v:

function ShortenText($text) {

        $chars = 50;

       if (strlen($text) >=  $chars)
       {
            $text = $text." ";
            $text = substr($text,0,$chars);
            $text = substr($text,0,strrpos($text,' '));
            $text = $text."...";
       }
        return $text;

    }

Thanks again

Don't forget to add comments, for you and any future maintainer. I couldn't figure out why you added the space.

$text = $text." ";
