Formatting Data Returned in PHP API Call

[jcrimmel]

I’m sure this is pretty easy for most of you, but I am no expert at writing code at all, and I need some help editing this code. I have a PHP API call shown below. The API call is returning data, but it is not formatted correctly.

Thanks in advance.

 

<?php

$curl = curl_init();
curl_setopt_array($curl, [
            CURLOPT_URL => "https://coingecko.p.rapidapi.com/simple/price?ids=everearn&vs_currencies=usd&include_market_cap=true&include_24hr_change=true&include_24hr_vol=true",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "GET",
            CURLOPT_HTTPHEADER => [
                        "X-RapidAPI-Host: coingecko.p.rapidapi.com",
                        "X-RapidAPI-Key: 3a8cf65…………………………..4b481b"
            ],
]);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);

if ($err) {
            echo "cURL Error #:" . $err;
} else {
            echo $response;
}

 

The results of the API call show up formatted as such:

{"everearn":{"usd":1.868e-05,"usd_market_cap":0.0,"usd_24h_vol":839.0915116166398,"usd_24h_change":1.5959917379692774}}

 

Using the results above, what I would like to do is format/mask the returned data to look like this:

Price: 0.00001868 (Ideally only show the decimals if needed. Some will have 8 decimal places, others will have 2, other prices will reach into xxx,xxx.xx)

24h Change: 1.59% (this could be a negative value as well)

Volume: 839.09

Market Cap: 0.0

use json_decode( ) on the returned results to get an array like

Array
(
    [everearn] => Array
        (
            [usd] => 1.868E-5
            [usd_market_cap] => 0
            [usd_24h_vol] => 839.09151161664
            [usd_24h_change] => 1.5959917379693
        )

)

then you can pick off the values you want with their keys.

Thank you Barnad.

While I've been using Joomla and editing very basic PHP for many years, I'm just recently starting to dive deeper into the coding side of it. I'm really just learning, so please excuse my ignorance. 

I assume your supplied code would be placed directly after the $results.... so, something like this?

<?php

$curl = curl_init();
curl_setopt_array($curl, [
            CURLOPT_URL => "https://coingecko.p.rapidapi.com/simple/price?ids=everearn&vs_currencies=usd&include_market_cap=true&include_24hr_change=true&include_24hr_vol=true",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "GET",
            CURLOPT_HTTPHEADER => [
                        "X-RapidAPI-Host: coingecko.p.rapidapi.com",
                        "X-RapidAPI-Key: 3a8cf65…………………………..4b481b"
            ],
]);
$response = curl_exec($curl);

Array
(
    [everearn] => Array
        (
            [usd] => 1.868E-5
            [usd_market_cap] => 0
            [usd_24h_vol] => 839.09151161664
            [usd_24h_change] => 1.5959917379693
        )

)

$err = curl_error($curl);
curl_close($curl);

if ($err) {
            echo "cURL Error #:" . $err;
} else {
            echo $response;
}

I didn't give you any code. I told you to use json_decode() on the results.

What I gave you was the output you will get after using json_decode();

[jcrimmel]

Thanks. I'll try to figure it out.

Come back if you get stuck.
