從PHP中訪問JSON數據

我從JSON獲取數據時遇到困難。從PHP中訪問JSON數據

我做一個foreach（）。因我從一個API獲取JSON格式的數據後，但我不能得到它的工作。

這裏是我的代碼：

的$ player_runes是數據庫變量，它的工作原理完全好，我的問題越來越runeID的數據爲每個陣列（頁）

foreach($player_runes->pages as $statplayerrunesfor){ 

$statplayerrunesforune0 = $statplayerrunesfor->slots->runeId; 

echo $statplayerrunesforune0; 

}

這裏是JSON數據：

"pages": [

json_decode（）;閱讀它 –

我已經有它解碼，我的問題是我如何獲得數據的符號runeId就像我在foreach中做了什麼？ – ForsakenHound

檢查我的答案，如果你使用'json_decode（）'它變成一個數組，而不是對象。 –

它應該爲你工作：

$player_runes = json_decode($variable_with_json, true); 
foreach($player_runes['pages'] as $statplayerrunesfor){ 

$statplayerrunesforune0 = $statplayerrunesfor['slots']['runeId']; 

echo $statplayerrunesforune0; 

}

解碼後它變成了一個不是對象的array。

不起作用，但我已經將其解碼爲一個數組，問題是我嘗試獲取數據的部分 - > runeId。有些原因不會使頁面變黑。 – ForsakenHound

無論如何，它總是更好地找出你自己的解決方案:) –

試試這個：

foreach(json_decode($player_runes->pages) as $statplayerrunesfor){ 

    $statplayerrunesforune0 = $statplayerrunesfor->{'slots'}->{'runeId'}; 

    echo $statplayerrunesforune0; 

}

希望工程:)

@ForsakenHound你是否在'json_decode'中使用'true'選項？然後它變成'$ player_runes ['pages']'。 – Barmar
