I'm sending data through POST from one application to another, using the file_get_contents function, I can't receive the data but using the variable $ _POST I can get it. Which would be the most suitable to receive the data?
I would like to send a token for authentication together, how could I do that?
$cont = json_decode(file_get_contents('php://input'), true);
echo gettype($cont);
NULL
And when I try the pre-defined variable, I can receive the data.
$cont = $_POST;
echo gettype($cont);
array
file_get_contents('php://input') gets the raw POST data as a string.
$_POST gets the POST data after PHP has automatically decoded it from application/x-www-form-urlencoded or multipart/form-data encodings.
If the data isn't encoded using one of those methods (e.g. if it is JSON as per your first example which uses json_decode) then $_POST won't be populated.

I want to retrieve the token as seen in the developer console image below. How do I do this?
PHP gets the raw request, and if you send JSON content it can get the raw data with the below method:
$postRaw = file_get_contents("php://input");
print_r($postRaw);
Sometimes $_POST return empty but if $_POST return data , you can basically use $_POST['postname']:
print_r($_POST);
I have a javascript (not from me) to sync information between client (javascript) and server (php) and javascript send to server GET and POST information, I can read easy GET information so I try to read $_POST information and cannot retrieve POST information.
I try print_r($_POST) and just returns Array() with nothing.
I try to look it with Firebug and Console into Firefox and I see that
How can I retrieve and treat json string into >Transmission de la requete< into my PHP code? I can easily retrieve GET parameters such as token, src and etc so I can't retrieve POST transmission.
Thank you for your helping !
I don't really get you. But since it's something like JSON request sent to the page. You can use the file_get_contents('php://input') to grab any JSON request sent. Then you can decode it into an object or an array.
Example
$request = file_get_contents('php://input');
To obtain an object
$input = json_decode($request);
So Input fields will be
$input->name; $input->password;
To Obtain an array
$input = json_decode($request, true);
So Input fields will be
$input[name]; $input[password];
I'm just trying to send a POST request with JS to server. But server has empty $_POST array. I could use HTTP_RAW_POST_DATA, but it'll be deprecated in PHP 5.6. Could I have posted data in my $_POST array?
Environment: Chrome, apache2, PHP, AngularJS (I'm using $http.post function).

The POST data must be in query string or multipart/form-data format to get decoded properly. Your data seems to be JSON, so you have to decode it by yourself:
$_POST = json_decode(file_get_contents('php://input'), true);
$_POST is populated by a request that is of type form-urlencoded or multipart/form-data. Typically it looks like:
foo=bar&ipsum=lorm
So kinda like a GET request.
Since you're posting JSON directly (which is awesome!) you can use:
$request_payload = file_get_contents("php://input");
See the docs for more info.
See by default, jQuery transmits data using Content-Type: x-www-form-urlencoded and the familiar foo=bar&baz=moe serialization. AngularJS, however, transmits data using Content-Type: application/json and { "foo": "bar", "baz": "moe" } JSON serialization, which unfortunately some Web server languages—notably PHP—do not unserialize natively.
so you can do this when you define your angular module:
angular.module('MyModule', [], function($httpProvider) {
// Use x-www-form-urlencoded Content-Type
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
});

looks like json data posting directly without any variable try with
$request = file_get_contents('php://input');
print_r($request);
or use a variable on posting data like
data{'myvar': data}
and will get on POST data like
print_r($_POST['myvar']);
I am trying to figure out, is there any way of sending raw json to php instead of POST parameter. If it is possible then which way is best i mean either request body or POST parameter.
Send an HTTP request which has a JSON string as its request body (here: using curl on the command line):
$ curl -d '{"foo":"bar"}' example.com/test.php
Read this request body in PHP:
$json = file_get_contents('php://input');
Decode it:
$data = json_decode($json, true);
PHP's $_POST superglobal is automatically populated as an array if the request body of a POST request contains URL encoded key-value pairs (e.g. foo=bar&baz=42). In the above example you're still using an HTTP POST request with "POST data". It just doesn't automatically end up in $_POST because PHP doesn't know how to decode JSON automagically.
Basic requirement is to know if we can iterate through $_POST when the request body payload has data sent in json format e.g.
{"City":{"countryCode": "IN","regionCode":"KR"}}
We are able to access this only if we send the data as
m={"City":{"countryCode": "IN","regionCode":"KR"}}
We are able to access this using $_POST['m']
The Content-Type is set to default application/x-www-form-urlencoded, when we set this as application/json $_POST is empty/null.
If we try to access this as $_POST instead of $_POST['m'] it returns null/empty.
NB: I am newbie to PHP. Is it possible to create webservices without any library. Without making use of any library can PHP accept the post request with json data.
To get raw POST data (as opposed to having to access individual POST variables such as $_POST['m']), you can use the following wrapper:
$json = file_get_contents('php://input');
You can read the manual on wrappers if you're interested in learning a bit more about them.
This is how i am getting data and saving it to my database.
$return = array();
$data = json_decode(stripslashes($_REQUEST['Data']));
$email = $data->{"paramA"};
$password = $data->{"paramB"};
i think it might help you.
