_php examples of methods for improving truncate in smarty to support Chinese

The examples in this article describe the ways in which Smarty improved truncate to support Chinese. Share to everyone for your reference, specific as follows:

Smarty's truncate does not support the interception of Chinese. Change the modifier.truncate.php in the plugins in the Smarty directory to the following.

 <?php/* Smarty plugin *--------------------------------------------------------- ----* Type:modifier * name:truncate * purpose:truncate A string to a certain length if necessary, * Optionall
Y splitting in the middle of a word, and * appending the $ETC string.
* Update:change substr to Msubstr and add fun msubstr.so it * can bu used in Chinese charset. *-------------------------------------------------------------/function Smarty_modifier_truncate ($string, $
  Length = n, $etc = ' ... ', $break _words = False) {if ($length = = 0) return ';
    if (strlen ($string) > $length) {$length-= strlen ($ETC); if (! $break _words) $string = Preg_replace ('//s+?
    /s+)? $/', ', Substrgb ($string, 0, $length + 1));
  Return Substrgb ($string, 0, $length). $etc;
else return $string; function Substrgb ($str, $start, $len) {for ($i =0; $i < $start + $len; $i + +) {$tmpstr = (ord ($str [$i]) >=161 && o RD ($str [$i])<=254&& Ord ($str [$i +1]) >=161 && ord ($str [$i +1]) <=254)? $str [$i]. $str [+ + $i]: $tmpstr = $str [$
    I];
  if ($i >= $start && $i < ($start + $len)) $tmp. = $tmpstr;
return $tmp; }/* Vim:set expandtab:/*?>
