how to send a json request in php? - php

Question

i have a register page for allow users to register. before register i need to validate their phone number. i have given a web-service address along with its parameters.
the parameters i have given:
http://*********
Method:POST
Headers:Content-Type:application/json
Body:
the following in:
{
"mobileNo":"0*********",
"service":"****",
"Code1":"*****",
"content":"hi",
"actionDate":"2017/09/26",
"requestId":"1"
}
and here the code i found in the Internet:
$data = array(
'mobileNo' => '****',
'service' => '***',
'Code1' => '*****',
'content' => '55',
'actionDate' => '2017/09/26');
$options = array(
'http' => array(
'method' => 'POST',
'content' => json_encode( $data ),
'header'=> "Content-Type: application/json" .
"Accept: application/json"
)
);
$url = "******";
$context = stream_context_create( $options );
$result = file_get_contents( $url, false, $context );
$response = json_decode( $result );
and here is error i face with when i test local:
file_get_contents(http://********/sms-gateway/sms-external-zone /receive): failed to open stream: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
and there is no error and no result(receive SMS) in response when i test online(cpanel server)
According to the given parameters, where do i wrong?
thanks in advance.

According to your Error, it seems your service did not respond. Have you tried to open it in a browser, to check if any response there?
Maybe the service you try to call requires you to provide a Static IP from your Webserver, as they only grant access on a IP based level. Means, your IP is blocked until they allow it.
I suggest you use cURL to do your request. This way you get future data to use for debugging, if anything fails. Still here, if the service does not respond, you want get any other information.
$data = array(
'mobileNo' => '****',
'service' => '***',
'Code1' => '*****',
'content' => '55',
'actionDate' => '2017/09/26');
$url = "******";
$ch = curl_init( $url );
// set data as json string
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode($data));
// define json as content type
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
// tell curl to fetch return data
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
// follow location if redirect happens like http to https
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
// send request
$result = curl_exec($ch);
// gives you the result - most of the time you only want this
var_dump($result);
// for debugging purpose, gives you the whole connection info
var_dump(curl_getinfo($ch));
// gives back any occurred errors
var_dump(curl_error($ch));
curl_close($ch);
Edit: I added the CURLOPT_FOLLOWLOCATION, as a request may gets redirected. We want to catch that as well. And I added the curl_close at the end. If it is closed, error or info data can be fetched.
