Question

Say I have the following loop in my view

foreach ($value as $row):
     echo $row['name'] . ', ';
endforeach;

This outputs a string like this in my browser

Geddy, Lee, Neil, Peart, Alex,

I wonder if anyone can suggest a method to truncate this string at n characters, for example

Geddy, Lee, Ne…

Since the string is being output from the loop I am unsure how to wrap a truncate function around this foreach.

Thanks for helping!

sample truncate function

function truncate_text($text, $nbrChar, $append='...') {
     if(strlen($text) > $nbrChar) {
          $text = substr($text, 0, $nbrChar);
          $text .= $append;
     }
     return $text;
}

Why not save the row values to a variable and truncate that variable and just echo that?

var $str = "";
foreach ($value as $row):
     $str .= $row['name'] . ', ';
endforeach;

echo truncate_text($str, 'whatever');
