Json problem in flickr

I have this json but I have no idea how to get 7796249@N02

a:2:{s:4:"user";a:3:{s:2:"i开发者_JAVA技巧d";s:11:"7796249@N02";s:4:"nsid";s:11:"7796249@N02";s:8:"username";a:1:{s:8:"_content";s:9:"ilhan.z.y";}}s:4:"stat";s:2:"ok";}

That is a serialized PHP array, not JSON. Use:

$array = unserialize('that response goes in here');

What language are you using? In Groovy, for example, you would do something like this:

import groovyx.net.http.*
@Grab(group='org.codehaus.groovy.modules.http-builder',
    module='http-builder', version='0.5.0' )


def http = new HTTPBuilder( 'http://twitter.com/statuses/' )

http.get( path: 'user_timeline.json',
        query: [id:'httpbuilder', count:5] ) { resp, json ->

println resp.status

json.each {  // iterate over JSON 'status' object in the response:
    println it.created_at
    println '  ' + it.text
  }
}

Edit after PHP tag added:

I'm not a PHP guy, but it looks like json_decode is what you need to use.
