you have to decode your Json data into an array : take a see here : https://stackoverflow.com/questions/7511821/how-to-convert-json-string-to-array — Yassine CHABLI, Dec 26 '17 at 00:27

You First need to convert the json text into a php array/object.

Use this code as an example:

<?php
$rawJSon="your long json here"
$data=json_decode($rawJson, true);
echo $data[0]["price_usd"];

Assuming this is your JSON string:

$raw = <<<EOT
[
    {
        "id": "bitcoin-cash", 
        "name": "Bitcoin Cash", 
        "symbol": "BCH", 
        "rank": "3", 
        "price_usd": "2957.36", 
        "price_btc": "0.211189", 
        "24h_volume_usd": "1339490000.0", 
        "market_cap_usd": "49908111624.0", 
        "available_supply": "16875900.0", 
        "total_supply": "16875900.0", 
        "max_supply": "21000000.0", 
        "percent_change_1h": "-0.09", 
        "percent_change_24h": "2.4", 
        "percent_change_7d": "34.95", 
        "last_updated": "1514247253"
    }
]
EOT;

Since you have a JSON object you need to use the arrow too specify an object property (notice the object curly braces in your JSON):

$data = json_decode( $raw );
echo $data[0]-> price_usd;

Or you can decode as an array instead of an object:

$data = json_decode( $raw, TRUE );
echo $data[0]['price_usd'];
