<?php 
if(preg_match('/<!--more-->/',$this->content)||mb_strlen($this->content, 'utf-8') < 270)
{
$this->content('阅读全文...');
}

{ 
$c=mb_substr($this->content, 0, 270, 'utf-8');

echo '</br><p class="more"><a href="',$this->permalink(),'" title="',$this->title(),'">阅读全文...</a></p>';

{
$this->content('阅读全文...');
}
else
{ 
$c=mb_substr($this->content, 0, 270, 'utf-8');
$c=preg_replace("/<[img|IMG].*?src=[\'\"](.*?(?:[\.gif|\.jpg|\.jpeg|\.png|\.tiff|\.bmp]))[\'|\"].*?[\/]?>/","",$c);
echo $c.'...';
echo '</br><p class="more"><a href="',$this->permalink(),'" title="',$this->title(),'">阅读全文...</a></p>';
}
?>

<?php 
if(preg_match('/<!--more-->/',$this->content)||mb_strlen($this->content, 'utf-8') < 270)
{
$this->content('阅读全文...');
}

{ 
$c=mb_substr($this->content, 0, 270, 'utf-8');
$c=preg_replace("/<[img|IMG].*?src=[\'\"](.*?(?:[\.gif|\.jpg|\.jpeg|\.png|\.tiff|\.bmp]))[\'|\"].*?[\/]?>/","",$c);
if(preg_match('/<pre>/',$c))
{
echo $c,'</code></pre>','...';;
}
