If you do var_dump($array) you can see the exact structure of it. Your current way of trying to get it doesn't make much sense.

The JSON from the API is this:

[
    {
        "id": "bitcoin-cash", 
        "name": "Bitcoin Cash", 
        "symbol": "BCH", 
        "rank": "3", 
        "price_usd": "3205.57", 
        "price_btc": "0.208515", 
        "24h_volume_usd": "4509330000.0", 
        "market_cap_usd": "54073197615.0", 
        "available_supply": "16868513.0", 
        "total_supply": "16868513.0", 
        "max_supply": "21000000.0", 
        "percent_change_1h": "-0.83", 
        "percent_change_24h": "-17.54", 
        "percent_change_7d": "71.22", 
        "last_updated": "1513885472"
    }
]

...and after converting it to an assoc array (by passing true to json_decode() as its 2nd param, fetching the rate should be done as:

$array[0]['price_usd']

Can you please complete the code its printing to me Array not the object price — john doe, Dec 21 '17 at 19:56
God Bless you man , i fixed it $rate = $array[0]['price_usd']; — john doe, Dec 21 '17 at 19:58
