retrieve linkedin profile url from php api -

i using simple linkedin php library create searching feature application. user can search through linkedin , retrieve matched users information. of right feature working properly, how can parse xml returned api , user's id create link profile?

this sample of array returned api call:

{   "numresults": 17325,   "people": {     "_count": 10,     "_start": 0,     "_total": 110,     "values": [       {         "firstname": "leon",         "headline": "digital marketing | mobile marketing | video marketing | seo/sem | digital media sales trainer",         "id": "efmhqotad3",         "lastname": "e. spencer",         "pictureurl": "http://m3.licdn.com/mpr/mprx/0_jogihrinvw_afca6prdyhpxzbdvfi3a6xywyhpxke7t0p5jql4sfq1kemxzr86fopjxjfqnef1i-"       }, 

if understand correctly, users profile url looks http://www.linkedin.com/profile/view?id=156996610 should able extract id api call , append view?id= query right? can simplexml php library?

by xml believe mean json.

one way in php using json_decode() function.

$url = file_get_contents("http://www.linkedin.com/profile/view?id=156996610");

$json =json_decode($url,true);

the second value "true" means returned associative array.

then can access whatever want response.

i.e user id..

$userid = $json['people']['values']['id'];

i suggest reading json_decode() documentation understand how works.
