Short Text, PHP

Question

I got this function:

function shorter($text, $chars_limit) {
  if (strlen($text) > $chars_limit) 
    return substr($text, 0, strrpos(substr($text, 0, $ch         


        

Answer 1

function shorter($input, $length)
{
    //no need to trim, already shorter than trim length
    if (strlen($input) <= $length) {
        return $input;
    }

    //find last space within length
    $last_space = strrpos(substr($input, 0, $length), ' ');
    if(!$last_space) $last_space = $length;
    $trimmed_text = substr($input, 0, $last_space);

    //add ellipses (...)
    $trimmed_text .= '...';

    return $trimmed_text;
}
