wordpress自定义摘要截取字数的代码

上山打老虎

代码如下:

function excerpt($limit) { 
 $excerpt = explode(' ', get_the_excerpt(), $limit); 
 if (count($excerpt)>=$limit) { 
   array_pop($excerpt); 
   $excerpt = implode(" ",$excerpt).'...'; 
 } else { 
   $excerpt = implode(" ",$excerpt); 
 } 
 $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt); 
 return $excerpt; 
}
