I'm trying to send byte array of image to my webservice in json object.But, It the request never hits my server. If I send just an empty array it hits the server and returns the json response. Below is my code. What is wrong with this code

```
<?php 

header('Content-type: application/json');
//Read an image from third party URL
$contents= file_get_contents('http://i2.cdn.turner.com/cnn/dam/assets/120612031415-granderson-speech-c1-main.jpg');
$byteArr = str_split($contents);
foreach ($byteArr as $val) 
{ 
 $points[] = ord($val); 
}
$output = join (" " , $points);
//echo($output);
//If i use "photo"=>[] in below array it works fine
$jsonArray = array("comments"=>"Hiee", "type"=>"test", "photo"=>[$output],"custid"=>"test@test.com");
$buzz = json_encode($jsonArray);
try {
//Webservice call to store the image in DB and send mail
$jsonResponse = @file_get_contents("http://localhost/example/json.htm?action=sendBuzzRequest&email=test@test.com&pass=test1234&buzz=".$buzz);
echo ($jsonResponse);
} catch(Exception $e)
{
 $e->getMessage();
}
?>

```

Your Help is very much appreciated.
