if(mb_strlen($blog['body']) >  300){
	echo mb_substr(<span style="color:#ff0000;">strip_tags($blog[&#39;body&#39;]," ")</span>, 0,  300,&#39;utf-8&#39;)."......";//注意这里允许空格
	echo "<span class = &#39;more_blog&#39;><a href = &#39;/blog/view/id/".$blog[&#39;id&#39;]."&#39;>阅读全文>></a></span>";
	echo "<hr>";
}
