Look, I'm doing tests with an api where I'm getting this json:
[
{
"id": "bitcoin",
"name": "Bitcoin",
"symbol": "BTC",
"rank": "1",
"price_usd": "18880.8",
"price_btc": "1.0",
"24h_volume_usd": "14088000000.0",
"market_cap_usd": "316267315150",
"available_supply": "16750737.0",
"total_supply": "16750737.0",
"max_supply": "21000000.0",
"percent_change_1h": "-0.74",
"percent_change_24h": "1.29",
"percent_change_7d": "11.39",
"last_updated": "1513649955"
}
]
I'm doing the code in PHP and would like to echo these things, follow my code (which is not working):
$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin/";
$result = file_get_contents($url);
$final = json_decode($result, true);
echo $final->{"price_usd"};
Who knows, could you help me?
Thanks for your attention.
