curl to php to post a json and audio - php

Question

I'm trying to convert a curl command to be used in a php script
curl -k -F "request={'timezone':'America/New_York','lang':'en'};type=application/json" -F "voiceData=#d8696c304d09eb1.wav;type=audio/wav" -H "Authorization: Bearer x" -H "ocp-apim-subscription-key:x" "http://example.com"
and here is my php script
<?
$data = array("timezone" => "America/New_York", "lang" => "en", "voiceData" => "d8696c304d09eb1.wav");
$data_string = json_encode($data);
$ch = curl_init('https://example.com');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Authorization: Bearer x',
'ocp-apim-subscription-key:x')
);
$result = curl_exec($ch);
?>
I understand that the send audio file bit is not right but i cant find an example how to post it.
I have edited this in response to the post fields but if I include $ch i get no output if don't include the output complains that no post request. Any ideas?
<?
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
$ch = curl_init('https://example.com');
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Authorization: Bearer x',
'ocp-apim-subscription-key:x')
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,
array('request' => json_encode(array('timezone' => 'America/New_York', 'lang' => 'en')),
'voicedata' => new CURLFile("d8696c304d09eb1.wav")
)
);
$result = curl_exec($ch);
echo $result;
?>

Answer 1

You're missing the request= in your POST fields. Also, sending files using #filename is deprecated, you should use the CURLFile class.
curl_setopt($ch, CURLOPT_POSTFIELDS,
array('request' => json_encode(array('timezone' => 'America/New_York', 'lang' => 'en')),
'voicedata' => new CURLFile("d8696c304d09eb1.wav")
)
);
