Looping through JSON with PHP to get children

It looks like your cURL request is to blame, you're not telling cURL you're expecting a response, so cURL just passes back a boolean success for your initial request, it sent it successfully.

From the PHP curl_exec page.

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

It's succeeding, but you're not telling it you're expecting a response, so it returns TRUE.

Try this:

$url = 'https://myapi.com/api?token=xxx&from_date='.$from_date.'&to_date='.$to_date;$options = array(    CURLOPT_RETURNTRANSFER => true,   // return web page <-- This is the important one that tells cURL you want a response.    CURLOPT_HEADER         => false,  // don't return headers    CURLOPT_FOLLOWLOCATION => true,   // follow redirects    CURLOPT_MAXREDIRS      => 10,     // stop after 10 redirects    CURLOPT_AUTOREFERER    => true,   // set referrer on redirect    CURLOPT_CONNECTTIMEOUT => 120,    // time-out on connect    CURLOPT_TIMEOUT        => 120,    // time-out on response); $ch = curl_init($url);curl_setopt_array($ch, $options);$result = curl_exec($ch);curl_close($ch);

2nd error

Now we've got cURL working lets address the result. Remember that when JSON is converted each brace ({) will produce an object, and each square bracket ([) will produce an array. So if we follow your JSON we can see that you will get an object back, containing the property results. You can access that using $responseData->results.

In your second foreach you're trying to access the property of an object. Results isn't an object, it's an array (look at your JSON, it contains a [, so it's an array). To get the rates follow through the JSON string and you'll see you need to do this:

foreach($responseData->results[0]->rates as $rate) {    echo $rate->id . "\n";}
