phpcms调用内容页图片并生成缩略图

{pc:content action="lists" catid="13" num="12" order="id DESC" moreinfo="1"} //moreinfo必须带，才能从副表中读取文章内容
	{loop $data $r}
		{php $str=$r[content]; $preg = '//i'; preg_match_all($preg, $str, $allImg); $new_arr=array_unique($allImg[1]);}
			{loop $new_arr $value}
            	
			{/loop}
	{/loop}
{/pc}
