ThinkPHP 截取字串有關問題

ThinkPHP　截取字串問題
剛用ThinkPHP　一個截取字串函數　但是模板裡卻輸不出來

代碼：
$news_list = $model_list->findall('',$fields,'dateline desc',$p->firstRow.','.$p->listRows);
/*截取字串*/
foreach ($news_list as $x=>$y) {
$news_list[$x]['content']=cut_str(Zmor_ireplace($y['content']),30,0,"UTF-8");//截取字串函數
}

//模板輸出
$page = $p->show();
$this->assign('news_list',$news_list);



------解決方案--------------------
$news_list[$x]['content']=msubstr(Zmor_ireplace($y['content']),0,30,"UTF-8");
