Get content from json with Php conditionally

I am struggling to get some informations/values from a json using php conditionally. To be more detailed, this is my case:
I have a json response that looks like this:

{
"IsSuccess": true,
"ResponseCode": 5000,
"ResponseMessage": "OK",

Using php, I want to retrieve value of SELL_RATE and BUY_RATE for combinations of currencies where FROM_CURR_NAME = "EUR" and TO_CURR_NAME = GBP; also FROM_CURR_NAME = "EUR" and TO_CURR_NAME = TRY; also FROM_CURR_NAME = "USD" and TO_CURR_NAME = GBP.
I have tried to get the values using $json["Data"]["result"]["RATE_TO_ALL"][17]["BUY_RATE"]; but unfortunately from the json the id [17] is changeing very offten and I am not getting the correct values. Beeing in this situation, the only solution I see is to filter json response based on combination of FROM_CURR_NAME and TO_CURR_NAME, and here I have stopped because at this moment, that is out of my league 🙂
Could someone help me with a solution please? What i have now is the followings:

$url = "example.com/myjson";
                $curl = curl_init($url);
                curl_setopt($curl, CURLOPT_URL, $url);
                curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

                $headers = array(
                    "Connection: keep-alive",
                    'sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="96", "Google Chrome";v="96"',
                    "sec-ch-ua-mobile: ?0",
                    "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36",
                    'sec-ch-ua-platform: "Windows"',
                    "Accept: */*",
                    "Origin: https://www.example.com",
                    "Sec-Fetch-Site: same-site",
                    "Sec-Fetch-Mode: cors",
                    "Sec-Fetch-Dest: empty",
                    "Referer: https://www.example.com/",
                    "Accept-Language: en-US,en;q=0.9,sq;q=0.8,ro;q=0.7",
                );
                curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
                curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
                curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
                $resp = curl_exec($curl);
                curl_close($curl);
                $json = json_decode($resp, true);

Thank you.

    You have to add a forEach loop

    $rates = $json['Data']['result']['RATE_TO_ALL'];
foreach ($rates as $rate) {
    $from_curr_name = $rate['FROM_CURR_NAME'];
    $to_curr_name = $rate['TO_CURR_NAME'];
    $sell_rate = $rate['SELL_RATE'];
    $buy_rate = $rate['BUY_RATE'];
    echo "$from_curr_name to $to_curr_name: Sell rate:$sell_rate, Buy rate: $buy_rate";
}

    You can achieve this by iterating through the JSON array and checking the values of FROM_CURR_NAME and TO_CURR_NAME for each item. If they match your specified combinations, you can extract the SELL_RATE and BUY_RATE values. Here’s how you can do it in PHP:

    // Your JSON decoding code
$url = "example.com/myjson";
$curl = curl_init($url);
// ... (your curl options)
$resp = curl_exec($curl);
curl_close($curl);
$json = json_decode($resp, true);

// Define the combinations you're interested in
$combinations = [
    ["FROM_CURR_NAME" => "EUR", "TO_CURR_NAME" => "GBP"],
    ["FROM_CURR_NAME" => "EUR", "TO_CURR_NAME" => "TRY"],
    ["FROM_CURR_NAME" => "USD", "TO_CURR_NAME" => "GBP"]
];

// Iterate through the RATE_TO_ALL array and extract the values for the specified combinations
foreach ($json["Data"]["result"]["RATE_TO_ALL"] as $rate) {
    foreach ($combinations as $combination) {
        if ($rate["FROM_CURR_NAME"] === $combination["FROM_CURR_NAME"] &&
            $rate["TO_CURR_NAME"] === $combination["TO_CURR_NAME"]) {
            $sellRate = $rate["SELL_RATE"];
            $buyRate = $rate["BUY_RATE"];
            // Do something with $sellRate and $buyRate
            echo "Sell Rate: $sellRate, Buy Rate: $buyRate";
        }
    }
}

    In this code, the $combinations array holds the combinations of FROM_CURR_NAME and TO_CURR_NAME that you want to extract. The code then iterates through the JSON array and checks if the current item’s combination matches any of the specified combinations. If a match is found, it extracts the SELL_RATE and BUY_RATE values for that combination.

    Make sure to replace the echo statement with whatever you want to do with the extracted rates. This code ensures you extract the correct rates based on your specified currency combinations.
