织梦实现截取标题时当大于截取的长度时加省略号的功能

{dede:arclist row='10'}
<li><a href="[field:arcurl /]"  title="[field:fulltitle/]">
[field:fulltitle runphp='yes']$titlefull = @me;$titleshow =cn_substr($titlefull,90);if($titlefull!=$titleshow){$dot = "…";}else{$dot="";}@me = $titleshow.$dot;[/field:fulltitle]
</a></li>
{/dede:arclist}

 上面的是截取标题长度为90的时候的方法
