PHP POST Request Special Characters - php

I'm trying to send a special character, such as ñ, through a POST request in PHP. When I do it, it comes out as ñ, what is wrong and how do I fix it?
I'm sending and receiving the post request in PHP, here is what I use to send it:
$url = '<url>';
$data = array('key' => 'ñ');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo $result;
Thanks in advance!

Try using this:
$data = array('key' => urlencode('ñ'));
And in the $url file:
$_POST['key']=urldecode($_POST['key']);
This is how I use to send special characters in GET and POST method with ajax, it must work for php too.

Sending a post request with parameters in php to get Json data

I'm trying to get some json data from another server that needs 3 parameters so that I can access it. I saw this code in internet but its not working. I have searched a lot and I haven't found a solution. When I run this code I get :
use pass and code are missing
(is the response from the server I'm requesting), I hope I made things clear if there's anything I didn't explain please do tell.
$url = 'http://xxxx/.js';
$data =http_build_query(array('user' => 'xx',
'pass' =>'xxx ',
'code' =>'xxx')
);
$options = array(
'http' => array(
'header' => "Content-type: application/json\r\n",
'method' => 'POST',
'content' => $data
)
);
$context= stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { }
echo $result ;
Try to change your payload to json...
$data = json_encode( array(
'user' => 'xxx',
'pass' => 'xxx',
'code' => 'xxx'
) );
and to remove \r\n from your content type
"Content-type: application/json"

PHP Post Request content contains Raw Data

I've been looking for a solution for such a long time for my issue.
But i just can't find any solutions and i'm not sure what exactly to search for.
I'll explain my problem here.
Currently i have this PHP script which works perfect and sends a successfully request and receives the respond.
<?php
$url = 'http://example.nl/index.php';
$data = array('url' => 'http://www.myip.nl/', 'verkort' => 'Verkort URL');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
?>
But i really need help with sending a request with the following content:
See screenshot: http://i.imgur.com/VgedJes.png
I need to add the 3 headers and i'm not sure how to tell a field/value is empty as you can see in the screenshot.
I just can't figure out how to do this.
I would really appreciate it if someone could help me out with this!
To Add Header :
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\nX-Requested-With: XmlHttpRequest",
'method' => 'POST',
'content' => http_build_query($data),
),
);
Keep in mind that X-Requested-Header can only be interpreted by your PHP application
To send a parameter with an empty value you can do as follow
$data = array('url' => 'http://www.myip.nl/', 'verkort' => 'Verkort URL', 'notMandatoryParam' => '');
Also in your PHP code, you must do a verification : if(empty($_POST['notMandatoryParam'])) {/*SKIP ME*/}

How send another POST from inside a POST

I am trying to send a POST but I am getting an empty post on my other script.
What I am doing wrong?
if(isset($_POST)){
$url = 'http://localhost:3000/post';
$data = $_POST;
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
}
This is for sync between 2 apps.
When I replace
$data = $_POST;
by
$data = array('key1' => 'value1', 'key2' => 'value2');
Works like a charm!
Thanks!
The problem was that some how, wordpress was deleting the $_POST at some point and after I've moved up my code to the top of the file, the problem was resolved.
Thanks you all!

PHP HTTP Request (stream_context_create)

Hi I am trying to get the following to work. It is making the HTTP request because I can see it at the other end but it is not passing over the two values and parameters.
Can anyone help?
<?php
$url = "http://example.com/ws.php?uid=0000&pin=0000";
$fields = array(
'target1' => $_GET['target1'],
'target2' => $_GET['target2']);
$data = http_build_query($fields);
$context = stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $data,
)
));
$result = file_get_contents($url, false, $context);
echo $data."<br />";
echo($result);
?>
If PHP 5.2, see PHP bug https://bugs.php.net/bug.php?id=41051
Description:
the http wrapper ignores 'header' option in stream_create_context( )
if the value is not given as a simple array; neither a string nor a
map (e.g. array('X-My-Header' => 'test')) will cause the additional
headers to be sent.
Based on the examples i've seen you need a \r\n at the end of the header value.
'header' => "Content-type: application/x-www-form-urlencoded\r\n"
apart from that you will also need to provide
"Content-Length: " . strlen($data) . "\r\n",

POST _viewstate with php

Hi I'm trying to send post values using a PHP script to an external website and get the result. My code is as follows
$postdata = http_build_query(
array(
'drpservice' => 091,
'drpdirection' => 1,
'drpbusstop' => 18051
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
echo $result;
However, it won't return the required results unless I can manage to send in the hidden _VIEWSTATE value.
Anyone able to help?
You need to first get the form page using a GET request, and then you can parse the page to get the _VIEWSTATE value using a regular expression.
Then when doing the POST pass the value you got for it.
