Substr Help needed please

Hello everyone,

i have a code snippet which shows random comments on my topsite

And with substr i made it to show only 40 character and replace the rest with "...."
Well is there a chance so i could add a link after the ....???

Here are the codes

the substr:

$review = $TMPL['review'];
$limit = '40';

   if (strlen($review) > $limit) {
      $review = substr($review, 0, strrpos(substr($review, 0, $limit), ' ')) . '...';
      }

$TMPL['review'] = $review;

Code (markup):

and this is the code for the link:
( that works when i place it after the substr, but not in the substr itself, where i need it, because i wanna show a link to the full review only if it was shortened )

$TMPL['random_review'] = "<a href=\"index.php?a=stats&amp;u={$TMPL['username']}&amp;all_reviews=1\">more</a> 
";

Code (markup):

I allready tried to place it different spots and variations, but all throwed errors like unexpected t_string out.

I hope you now what i mean and hope someone can help me out, thanks

 

Here, I wrote a function for you:

function limitText($text, $limit, $linkurl) {
	return (strlen($text) > $limit) == true ? substr($text, 0, $limit) . "... <a href=\"{$linkurl}\">more</a>" : $text;
}

Code (markup):

$limit is the number of characters to show before showing the elipsis. $text is the text to limit the length of. $linkurl is the url to link the "more" link to.

Example:

echo limitText("Hello, this message will cut off after 30 characters!  Hello, this message will cut off after 30 characters! ", 30, "http://www.google.com");
