Answer 1

Simply you have to update you index.php script with these line of code.
index.php
<?php
$data = array("name"=>"john","age"=>31);
$string = http_build_query($data);
echo $string;
$ch = curl_init("http://localhost/scrap_practise/data.php");
curl_setopt($ch, CURLOPT_POST,true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if( ! $result = curl_exec($ch))
{
trigger_error(curl_error($ch));
}
curl_close($ch);
// to see the return result uncomment the below line code.
//print_r($result);
?>
For more options or function reference see this link - http://php.net/manual/en/function.curl-exec.php
Hope this will help to resolve your issue !!

Try this code, I hope it will work for you...
<?php
$url = 'http://localhost/scrap_practise/data.php';
$data = array("name"=>"john","age"=>31);
$string = http_build_query($data);
echo $string;
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST,true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
print_r($result) ;
curl_close($ch);
?>
In data.php file
<?php
echo 'finlly in'; // this never echos
if(isset($_POST['name'],$_POST['age']))
{
echo "<pre>"; print_r($_POST);
}
?>
This will Output :
finlly in
Array
(
[name] => john
[age] => 31
)
