The problem is:

$limita_str = substr($str, 0, $limita);
$ultimo = strrpos($limita_str, ' ');
return substr($str, $ultimo).'...';

Let's translate what you're doing:

$limita_str is limiting $str from the first character ( 0 ) to what is defined in $limita which is the second argument of the function, hence% to 0 .

$limita is actually the position of the last space ( $ultimo ) found within .

The $limita_str returns the text of return from $str space ( $ultimo ) to infinity, then returns from $str to infinity.

Did you find the problem?

The problem could simply be solved like this:

public function limitar($str, $limita = 100, $limpar = true){

       if($limpar = true){
           $str = strip_tags($str);    
       }

       return mb_substr($str, 0, $limita).'...';
}

Requires the Multibyte String , I believe that $ultimo by default includes this.

This will not actually cut to the last space, but it will not break a character in the middle, ie it will not show these " php-common ", as in �� , which is not multi-byte. / p>

If you really want to use substr and preserve the function as it is, use:

public function limitar($str, $limita = 100, $limpar = true){
    if($limpar = true){
        $str = strip_tags($str);
    }
    if(strlen($str) <= $limita){
        return $str;
    }
    $limita_str = substr($str, 0, $limita);
    $ultimo = strrpos($limita_str, ' ');
    return substr($limita_str, 0, $ultimo).'...';
}
