real-time parsing of JSON responses using PHP

I am currently conducting research for my graduate program in finance on the topic of crypto currencies such as bitcoin. I am focusing on extracting individual data from JSON responses provided by the cryptsy API, which is a platform for trading crypto currencies. The API code sample I am using can be accessed through the following URL: . Initially, I am trying to retrieve my account balances. Any assistance you could offer would be greatly appreciated.

The responses I am receiving have the following format:

$result = api_query("getinfo");
$json = file_get_contents($result);
$json2 = json_decode($json, true);
foreach($json2->attachments->balances_available AS $attach) {
    file_put_contents('test.txt', $attach, FILE_APPEND);

}

echo "<pre>".print_r($json2, true)."</pre>";

Error Message:

Warning: file_get_contents() expects parameter 1 to be a valid path, array given in /Users/Aditya/Desktop/PHP-1.php on line 45

Warning: Invalid argument supplied for foreach() in /Users/Aditya/Desktop/PHP-1.php on line 47

Any guidance would be highly appreciated, as I have searched extensively across various forums and as I do not come from a computer science background. Thank you for your time and understanding once again.

Answer 1

Answer №1

The `retrieve_data` function is designed to deliver an array directly:

$data_array = retrieve_data("fetch_details");

Therefore, there is no need to utilize either file_get_contents or json_decode on the `result_set` variable.

At this stage, it's a basic array, so simply access it using `[]`, without needing to traverse through properties using `->`. It's uncertain if it's contained within `["attachments"]`. Refer to var_dump($data_array) for the exact structure.

You can iterate over it like this:

foreach ($data_array["attachments"]["details_info"] as $detail_key => $detail_value) {
    print " $detail_key == $detail_value \n<br>";
}

If you intend to save it in a file (you may want to specify the format), you can append it in a similar manner:

foreach (/* as demonstrated above*/) {
    file_put_contents(
        'records.txt',
        " $detail_key holds $detail_value information \n",
        FILE_APPEND
    );
}
