Curl Post using PHP - php

Question

This is mi First Post on Stackoverflow.
I need to do a Curl Post to an SMS Gateway with PHP but I´d never done it, the manual says I should do something like this
curl -u admin:admin -d '{"text":"Hello.","port":[0],"param":[{"number":"123456","text_param":["John"],"user_id":1}]}’ –H "Content-Type:
application/json" http://192.168.1.252/api/send_sms
#I tried some users post, but I can´t get to get it working.
<?php
$ch = curl_init();
$username='admin';
$password='admin';
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_URL,"http://192.168.1.252/api/send_sms");
curl_setopt($ch, CURLOPT_POST, 1);
$data = array(
'text' => "TEXT TO BE SEND",
'port' => 0,
'number'=>"123456",
'text_param'=>"John",
'user_id'=>1
);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
#Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
$errno = curl_errno($ch);
$error_message = curl_strerror($errno);
echo "cURL error ({$errno}):\n {$error_message}";
curl_close ($ch);
#Further processing ...
if ($server_output == "OK") { echo "OK"; } else { echo "FAILED"; }
?>

Answer 1

Solved it,
Thanks a lot anyway. I added content type with
curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json'));
and redone the $data to meat specs.
Thanks
