Coinmarketcap API call with PHP and choose data set with slug-CodePudding

I tried to do my first API calls which worked finally with help from this great users here in this community. Thanks again. I want to choose data[1] or the currency with symbol. So i could use a $variable from my CMS. Maybe someone can show me a way how i can change this call to symbol. Here is my API call.

$url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest";

$headers = [
  'Accepts: application/json',
  'X-CMC_PRO_API_KEY: ___YOUR_API_KEY_HERE___'
];

$request = "{$url}"; // create the request URL

$curl = curl_init(); // Get cURL resource
// Set cURL options
curl_setopt_array($curl, array(
  CURLOPT_URL => $request,            // set the request URL
  CURLOPT_HTTPHEADER => $headers,     // set the headers 
  CURLOPT_RETURNTRANSFER => 1         // ask for raw response instead of bool
));

$response = curl_exec($curl); // Send the request, save the response
$json = json_decode($response);
curl_close($curl); // Close request

$price = $json->data[1]->quote->USD->price; echo $price;

CodePudding user response：

You get the data block IDs with array_column(), then you get the symbol's data block ID with array_search():

$data_ids = array_column($json->data, 'symbol');
$symbol_data_id = array_search('ETH', $data_ids);
$price = $json->data[$symbol_data_id]->quote->USD->price;

Or as an oneliner:

$price = $json->data[array_search('ETH', array_column($json->data, 'symbol'))]->quote->USD->price;
