Excerpt function problem

[daniel.s]

Hello,

I'm using a function to limit an entry to a predetermined number of characters. This is what it looks like:

<?php
    
    // Excerpts a field to $limit length
    
    function excerpt($str, $limit = 400, $endstr = '…'){
    $str = strip_tags($str);
    if(strlen($str) <= $limit) return $str;
    $out = substr($str, 0, $limit);
    $pos = strrpos($out, " ");
    if ($pos>0) {
    $out = substr($out, 0, $pos);
    }
    return $out .= $endstr;
    }

?>

It works like a charm but sometimes i want to limit two different fields within the same function:

<?php echo excerpt($result->summary. $result->body); ?>

This works 'OK' but this way i can't get a space between the summary text and the body text. It's i minor issue but it looks kinda dull. For example: "Hello, this is the summary.And this is the body text."

My PHP knowledge is low but my guess is that the problem arises with the "strip_tags" function. Is there any way around this? 

Thanks for help

There is no space because you didn’t put one there

Why not do $partone . ' ' . $parttwo?

Edit: Also, upvote for using a proper ellipse char.

I always wondered, why there aren't easy shortcuts for all those nice typographical chars on PC. For macs it's nearly faster to type
alt + . instead of ". . ." .

How do you think I use typographic quotes in nearly all my posts
