Send parameters to a URL and get output from that page

Question

I have 2 pages say abc.php and def.php. When abc.php sends 2 values [id and name] to def.php, it shows a message "Value received". Now how can I send those 2 values to def.php without using form in abc.php and get the "Value received" message from def.php? I can't use form because when user frequently visits the abc.php file, the script should automatically work and get the message "Value received" from def.php. Please see my example code:

abc.php:

 <?php 
  $id="123";
  $name="blahblah";
   //need to send the value to def.php & get value from that page
  // echo $value=Print the "Value received" msg from def.php;     
 ?>

def.php:

 <?php
  $id=$_GET['id'];
  $name=$_GET['name'];
  if(!is_null($id)&&!is_null($name))
  {  echo "Value received";}
  else{echo "Not ok";}
 ?>

Is there any kind heart who can help me solve the issue?

get ans pls see the wimvds code below: $f = file_get_contents('your.domain/def.php?id=123&name=blahblah'); echo $f; — riad

First make up your mind : do you want GET or POST parameters.

Your script currently expects them to be GET parameters, so you can simply call it (provided that URL wrappers are enabled anyway) using :

$f = file_get_contents('http://your.domain/def.php?id=123&name=blahblah');

To use the curl examples posted here in other answers you'll have to alter your script to use $_POST instead of $_GET.

You can try without cURL (I havent tried though):

Copy pasted from : POSTing data without cURL extension

// Your POST data
$data = http_build_query(array(
    'param1' => 'data1',
    'param2' => 'data2'
));

// Create HTTP stream context
$context = stream_context_create(array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-Type: application/x-www-form-urlencoded',
        'content' => $data
    )
));

// Make POST request
$response = file_get_contents('http://example.com', false, $context);

Taken from the examples page of php.net:

// create curl resource
$ch = curl_init();

// set url
curl_setopt( $ch, CURLOPT_URL, "example.com/abc.php");

//return the transfer as a string
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);

// $output contains the output string
$output = curl_exec( $ch );

// close curl resource to free up system resources
curl_close( $ch );

Edit: To send parameters

curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, array('var1=foo', 'var2=bar'));

<?php
$method = 'GET'; //change to 'POST' for post method
$url = 'http://localhost/browse/';
$data = array(
    'manufacturer' => 'kraft',
    'packaging_type' => 'bag'
    );

if ($method == 'POST'){
//Make POST request
    $data = http_build_query($data);
    $context = stream_context_create(array(
        'http' => array(
            'method' => "$method",
            'header' => 'Content-Type: application/x-www-form-urlencoded',
            'content' => $data)
        )
    );
    $response = file_get_contents($url, false, $context);
}
else {
// Make GET request
    $data = http_build_query($data, '', '&');
    $response = file_get_contents($url."?".$data, false);
}
echo $response;
?>

get inspired by trix's answer, I decided to extend that code to cater for both GET and POST method.
