Twilio cURL calling a phone

Question

Based on the documentation of Twilio and Curl I have a php curl routine:

function twilio($mobile,$msg,$twoCode){
$url = 'https://api.twilio.com/2010-04-01/Accounts/'.TWILIO_ACCOUNT_SID.'/Calls.json';
$CallURL = 'http://Myweb.com/code/say/'.$twoCode;
$auth = TWILIO_ACCOUNT_SID.":".TWILIO_AUTH_TOKEN;
$fields = array(
 'To' =>  $mobile  ,
 'From' => '+16262471234'  , // My Number
 'Url' => urlencode( $CallURL ) ,
 'Method'=>'GET' ,
 'FallbackMethod'=>'GET',
 'StatusCallbackMethod'=>'GET',
 'Record'=>'false'
);
$post = http_build_query($fields);
$curl = curl_init($url);
// Set some options - we are passing in a useragent too here
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_USERAGENT , 'Mozilla 5.0');
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Length: 7' ));
curl_setopt($curl, CURLOPT_USERPWD, $auth);
curl_setopt($curl, CURLOPT_VERBOSE , true);
$resp = curl_exec($curl);
curl_close($curl);
}

It gives me an error:

{"code": 21213, "message": "No 'From' number is specified", "more_info": "https://www.twilio.com/docs/errors/21213", "status": 400}

I tried all the options, can anyone help?

I edited and added a "+" for the "From" number. But still the error remains the same.

Thanks in advance!

Twilio Developer Evangelist here.

Your code is really close. Just two small changes should resolve your issue. First you need to remove this line: curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Length: 7' ));

This was truncating your POST data which resulted in the "From" information not being sent.

Second, you don't need to urlencode the $CallURL because curl handles this for us.

Once you make both of these changes your code should look like this and run without an error:

function twilio($mobile,$msg,$twoCode){
  $url = 'https://api.twilio.com/2010-04-01/Accounts/'. TWILIO_ACCOUNT_SID.'/Calls.json';
  $CallURL = 'http://Myweb.com/code/say/'.$twoCode;
  $auth = TWILIO_ACCOUNT_SID .":". TWILIO_AUTH_TOKEN;
  $fields = array(
   'To' =>  $mobile  , 
   'From' => '+16262471234'  , // My Number
   'Url' => $CallURL,
   'Method'=>'GET' ,
   'FallbackMethod'=>'GET',
   'StatusCallbackMethod'=>'GET',
   'Record'=>'false'
  );
  $post = http_build_query($fields);
  $curl = curl_init($url);
  // Set some options - we are passing in a useragent too here
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl, CURLOPT_USERAGENT , 'Mozilla 5.0');
  curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
  curl_setopt($curl, CURLOPT_USERPWD, $auth);
  curl_setopt($curl, CURLOPT_VERBOSE , true);

  $resp = curl_exec($curl);

  curl_close($curl);
}

Let me know if this gets your issues resolved.
