Note Submitter: andy@tagish.com ---- Neotropic's sentence truncating code is a little ineffecient - there's no need to chop the sentence into words or indeed chop the words into characters to find out how long they are. This does the trick a little more succinctly I think: function truncate($str, $len, $el = '...') { if (strlen($str) > $len) { $xl = strlen($el); if ($len < $xl) { return substr($str, 0, $len); } $str = substr($str, 0, $len-$xl); $spc = strrpos($str, ' '); if ($spc > 0) { $str = substr($str, 0, $spc); } return $str . $el; } return $str; }
