的[？我如何從JSON中提取數據與PHP（可能的複製https://stackoverflow.com/questions/29308898/how-do-i-extract-data-from -json-with-php） –

查看數組make：print_r（$ data）; –

WORK：echo $ data [0] ['price_usd']; –

$數據對象的數組，所以你不能得到像數據那。試試這個代碼：

$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin-cash/"; 
$dataRaw = file_get_contents($url); 
$data = json_decode($dataRaw); 
$coin = $data[0]; 
foreach ($data as $key => &$value) { 
    $value = (array)$value;//convert Object to array 
    echo $value['price_usd']; 
}
