    The global variable is $_POST, not _POST. Also it might be that you are sending the data via GET method, in which case you need to use the $_GET global variable.

    If you want to check for either POST or GET method, you can use the global variable $_REQUEST. Sample code bellow:

    <html>
<body>
<form method="POST" action="postdata.php">
<input type="text" name="mydata" />
<input type="submit">
</form>
</body>
</html>

    file postdata.php:

    <?php

$result = $_POST['mydata'];
echo $result;

    $post_body = file_get_contents('php://input');

    php://input allows you to read raw POST data. It is a less memory intensive alternative to $HTTP_RAW_POST_DATA and does not need any special php.ini directives. php://input is not available with enctype="multipart/form-data".

    Maybe you misspelled it. The array's correct name $_POST.

    Try this

    <?php
var_dump($_POST);

    and see what happens.
