php - Notice: Undefined offset & Trying to get property of non-object -


i trying pull data json_decode array, have done before time getting issues.

this json looks like.

{ "achievementpercentages": {     "achievements": [         {             "name": "tf_scout_long_distance_runner",             "percent": 54.668815612792969         },         {             "name": "tf_heavy_damage_taken",             "percent": 47.104038238525391         },         {             "name": "tf_get_consecutivekills_nodeaths",             "percent": 44.668777465820312         },         {             "name": "tf_pyro_camp_position",             "percent": 36.480117797851563         },         {             "name": "tf_kill_nemesis",             "percent": 34.392494201660156         },         {             "name": "tf_burn_playersinminimumtime",             "percent": 33.580135345458984         },         {             "name": "tf_pyro_burn_medicpair",             "percent": 32.748367309570312         },

and code this

$achname = $decodedach->achievementpercentages->achievements[$achcounter]->name; $achpercent = $decodedach->achievementpercentages->achievements[$achcounter]->percent;

the $achcounter present in while statement, in effort achievements seperately. don't think part wrong, how trying access data in array. don't see wrong though.

any appreciated.

full while statement requested

        while($achcounter < $responsecount)     {         $appid = $decodedsteam->response->games[$achcounter]->appid;         $achievementurl = 'http://api.steampowered.com/isteamuserstats/getglobalachievementpercentagesforapp/v0002/?gameid='.$appid.'&format=json';         $jsonach = file_get_contents($achievementurl);          $decodedach = json_decode($jsonach);         //var_dump($decodedach);         $achname = $decodedach->achievementpercentages->achievements[$achcounter]->name;         $achpercent = $decodedach->achievementpercentages->achievements[$achcounter]->percent;         //echo $achievementurl;         $sql = "insert steamid".$steamid."(name, percent) values ('".$achname."','".$achpercent."')";         $achcounter++;      }

you need iterate again after fetch data url. $achcounter usefull $decodedsteam, not $decodedach:

while($achcounter < $responsecount) {     $appid = $decodedsteam->response->games[$achcounter]->appid;     $achievementurl = 'http://api.steampowered.com/isteamuserstats/getglobalachievementpercentagesforapp/v0002/?gameid='.$appid.'&format=json';     $jsonach = file_get_contents($achievementurl);      $decodedach = json_decode($jsonach);     //var_dump($decodedach);     foreach($decodedach->achievementpercentages->achievements $achievement) { //here         $achname = $achievement->name;         $achpercent = $achievement->percent;         //echo $achievementurl;         $sql = "insert steamid".$steamid."(name, percent) values ('".$achname."','".$achpercent."')";     }     $achcounter++; }

These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners.
