PHP with JSON decode and steam api -


i new php @ stage, same openid libraries. want make website steam users need display inventory. i've downloaded example things thing written still need else. training took else inventory, similiar. didn't make hope can me.

that's example looking @ while trying decode data.

{ "response": {     "players": [         {             "steamid": "76hidden",             "communityvisibilitystate": 3,             "profilestate": 1         }     ]  }

}

and code in php looks like

$url2 = file_get_contents("url"); $content = json_decode($url2, true); $_session['steam_steamid'] = $content['response']['players'][0]['steamid']; $steamprofile['steamid'] = $_session['steam_steamid'];

and 1 above working well. please explain me why there 0 between "steamid" , "players"? looks session name matters, right? doing tests , when changed name session didn't work.

so here's working on json code: 

{     "friendslist": {         "friends": [             {                 "steamid": "765hidden",                 "relationship": "friend",                 "friend_since": 1428495026             },             {                 "steamid": "764hidden",                 "relationship": "friend",                 "friend_since": 1355599210             },             {                 "steamid": "764hidden",                 "relationship": "friend",                 "friend_since": 1423504205             },             more friends         ]      } }

so want steamid , got no idea how it. i've tried relationship steamid used above:

$url3 = file_get_contents("url2"); $content2 = json_decode($url3, true); $_session['steam_relationship'] = $content2['friendslist']['friends'][0]['relationship']; $steamfriends['friend'] = $_session['steam_relationship'];

and of course echo $steamfriend['friend'] not working. see person made these php files know session names (if need right work). ideas can find it?

i feel ashamed can't figure myself.

regards.

the first json 

{   "response": {     "players": [       {         "communityvisibilitystate": 3,          "profilestate": 1,          "steamid": "76hidden"       }     ]   } }

translates php array

$content = array(     "response" => array(         "players" => array(             array(                 "communityvisibilitystate" => 3,                 "profilestate" => 1,                  "steamid" => "76hidden"                          )         )     ) )

the players array of arrays (hash arrays), access first player need use index number ($content["response"]["players"][0]["steamid"]) if there 1 player in players array.

to steamids second array, need run simple foreach:

$friendids = array(); foreach ($content2["friendslists"]["friends"] $friend) {     $friendids[] = $friend["steamid"]; } # array("764hidden", "764hidden", "764hidden") var_export($friendids);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
