In PHP I have the following error: ErrorException: var_export does not handle circular references. When I Googled it I found some stackoverflow posts but they didn't explain what it is!
This is the code that is causing this:
$client = new Client(config('app.twilio_sid'), config('app.twilio_token'));
$twilio_call = $client->calls($input['CallSid'])->fetch();
$twilio_call = (array) $twilio_call;
Log::debug("Twilio Call Debugging");
Log::debug($twilio_call);
$call->where('sid',$input['CallSid'])->update(['calls' => $twilio_call]);
It should be getting a Json object which I cast to an array so that I can insert it into the database later. The error is caused in the update.
Please tell me what a circular reference is, and what might cause the error.
