Help needed getting data from array

schwim

Hi there everyone,

I'm very bad at this array thing. I simply need the value of 'icon' from this array:

Array
(
    [id] => 5038
    [title] => Ragefire Chasm Guild Run
    [points] => 10
    [description] => Defeat Taragaman the Hungerer while in a guild group.
    [rewardItems] => Array
        (
        )

[icon] => spell_shadow_summonfelguard
[criteria] => Array
    (
        [0] => Array
            (
                [id] => 14320
                [description] => Taragaman the Hungerer
            )

    )

)

So, borrowing from some other code I'm using, I tried this:

		$adata = json_decode($result, true);
		print_r($adata);
		foreach($adata as $adatum){
			$aicon = $adatum['icon'];
		}

when I print_r adata, it's printing properly but when I print aicon, it's empty. Here's what the source print looks like when I try it:

json_url is http://us.battle.net/api/wow/achievement/5038<br />
Array
(
    [id] => 5038
    [title] => Ragefire Chasm Guild Run
    [points] => 10
    [description] => Defeat Taragaman the Hungerer while in a guild group.
    [rewardItems] => Array
        (
        )

[icon] => spell_shadow_summonfelguard
[criteria] => Array
    (
        [0] => Array
            (
                [id] => 14320
                [description] => Taragaman the Hungerer
            )

    )

)
aicon is: <br />

Could someone help me by telling me what I'm doing wrong to get the value for $aicon?

You should be accessing $adata['icon'].

Hi there laser and thanks very much for your reply.

So should I be getting ride of the ($adata as $adatum) and simply change that line to foreach{

Well, I looked at the JSON, and it is:

{
    "id": 5038,
    "title": "Ragefire Chasm Guild Run",
    "points": 10,
    "description": "Defeat Taragaman the Hungerer while in a guild group.",
    "rewardItems": [],
    "icon": "spell_shadow_summonfelguard",
    "criteria": [{"id": 14320, "description": "Taragaman the Hungerer"}]
}

This corresponds to the PHP code:

$data = array(
    "id" => 5038,
    "title" => "Ragefire Chasm Guild Run",
    "points" => 10,
    "description" => "Defeat Taragaman the Hungerer while in a guild group.",
    "rewardItems" => array(),
    "icon" => "spell_shadow_summonfelguard",
    "criteria" => array(array("id" => 14320, "description" => "Taragaman the Hungerer"))
);

Do you get how to access the elements of the array now? 🙂
