How to grab string between two keywords in PHP

Not sure if this has been answered before - how can I grab string between two keywords?

For instance the string between a 'story' and a '?',

http://mywebsie.com/hello/blog/story/archieve/2012/5/?page=1    
 http://mywebsie.com/blog/story/archieve/2012/4/?page=1
 http://mywebsie.com/blog/story/archieve/2012/?page=4
 

I just want,

story/archieve/2012/5/
 story/archieve/2012/4/
 story/archieve/2012/
 

EDIT:

If I use parse_url,

$string = parse_url('http://mywebsie.com/blog/story/archieve/2012/4/?page=1');
 echo $string_uri['path'];
 

I get,

/blog/story/archieve/2012/4/
 

but I don't want to include 'blog/'
