If you want to substring the middle of a string with another and keep the words intact:

Plain TextExpand 
  1. function strMiddleReduceWordSensitive ($string, $max = 50, $rep = '[...]') {
  2.    $strlen = strlen($string);
  3.  
  4.    if ($strlen <= $max)
  5.        return $string;
  6.  
  7.    $lengthtokeep = $max - strlen($rep);
  8.    $start = 0;
  9.    $end = 0;
  10.  
  11.    if (($lengthtokeep % 2) == 0) {
  12.        $start = $lengthtokeep / 2;
  13.        $end = $start;
  14.    } else {
  15.        $start = intval($lengthtokeep / 2);
  16.        $end = $start + 1;
  17.    }
  18.  
  19.    $i = $start;
  20.    $tmp_string = $string;
  21.    while ($i < $strlen) {
  22.        if ($tmp_string[$i] == ' ') {
  23.            $tmp_string = substr($tmp_string, 0, $i) . $rep;
  24.            $return = $tmp_string;
  25.        }
  26.        $i++;
  27.    }
  28.  
  29.    $i = $end;
  30.    $tmp_string = strrev ($string);
  31.    while ($i < $strlen) {
  32.        if ($tmp_string[$i] == ' ') {
  33.            $tmp_string = substr($tmp_string, 0, $i);
  34.            $return .= strrev ($tmp_string);
  35.        }
  36.        $i++;
  37.    }
  38.    return $return;
  39.    return substr($string, 0, $start) . $rep . substr($string, - $end);
  40. }
