PHP Curl gets no return value

Server-side functions
function order_kb () {
$expressodd [0][' odd ']= ' 560860393435 ';
$expressoddjson = Json_encode ($expressodd);
return $expressoddjson;
}

Client request PHP File
$post _data = Array ();
$url = ' http://www.test.com/index.php?m=user&a=order_kb ';
$o = "";
foreach ($post _data as $k = $v)
{
$o. = "$k =". UrlEncode ($v). " & ";
}
$data =substr ($o, 0,-1);
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_post, 1);
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, curlopt_header,0);
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_postfields, $data);
$result = curl_exec ($ch);
Curl_close ($curl);
Print_r (Json_decode ($result, TRUE));
Print_r (Json_decode ($result, TRUE) [0][' odd ']);//print out to see the results
?>
Why can't I get the return value? Print out a blank page

If you can't simulate execution, then it's definitely not getting the real data.

I wrote that web address casually.

Then you're too bored.

The actual request is "http://www.danhaoxia.com/index.php?m=user&a=order_kb"; Look at this.

$url = ' http://www.danhaoxia.com/index.php?m=user&a=order_kb '; Echo file_get_contents ($url);

Have

BOM head not to say, there is no JSON shadow

$url = ' http://www.danhaoxia.com/index.php?m=user&a=order_kb '; Echo file_get_contents ($url);

That should be the test that I just added to the server, and now I've removed the

Go is removed, but only the BOM head is left
How do you call the ORDER_KB function?

ORDER_KB is not a function of the server? How do you call it?

But he did not return the data, you did not open Ajax mode it?

No, just don't know why the value of return will not be taken

You did not turn on Ajax mode, how does the return value of order_kb output?
Don't you even read the manual?

How to drive? Just learn, don't understand
