如何将这一行从PHP转换为Ruby?

问题描述:

I have trouble with converting the following line from PHP to Ruby:

strtolower(preg_replace(array('/[^a-zA-Z0-9 -]/', '/[ -]+/', '/^-|-$/'), array('', '-', ''), trim($str)));

Is it possible to accomplish this in one line just like in here?

将以下行从PHP转换为Ruby时遇到问题: p>

   strtolower(preg_replace(array('/ [^ a-zA-Z0-9  - ] /','/ [ - ] + /','/ ^  -  |  -  $ /'),array('',  ' - ',''),trim($ str))); 
  code>  pre> 
 
 

是否可以像在这里一样在一行中完成此操作? p > div>

str.strip.gsub(/[^a-zA-Z0-9 -]/, '').gsub(/[ -]+/, '-').gsub(/^-|-$/, '').downcase

could be further simplified to:

str.strip.gsub(/[ -]+/, '-').gsub(/[^a-z \d-]|^-|-$/i, '').downcase
