PHP $_POST returns null values

Question

This is my html code:

<form style="width: 20%; margin: auto;" action="subscribe.php" method="post" id="subscribeToNews">
<fieldset>
<legend>Subscribe:</legend>
<label for="subName">First Name:</label><br /><input type="text" id="subName" name="subName" /><br />
<label for="subEmail">Email:</label><br /><input type="text" id="subEmail" name="subEmail"   /><br />
<input style="width: inherit;" type="submit" value="Subscribe" />
</fieldset>
</form>

This is the subscribe.php file:

<?php
$con = mysqli_connect('95.76.197.98','root','','accounts');
print_r($_POST);
if (isset($_POST["subName"]) && isset($_POST["subEmail"])){
$subUser = $_POST["subName"];
$subEmail = $_POST["subEmail"];
echo "$subUser"."<br />"."$subEmail";
}
?>

I have really tried a lot of things out there on the Internet and nothing seems to work for me. Any ideas?
Also looks like the get method works for this...

Other than your if not closed, I don't see anything wrong. — AyB

How can you say it returns NULL value? Did you try print_r($_POST) ? — dikesh

Could by related to your nginx configuration.

Try:

$post = file_get_contents("php://input");

No, it's not. I have other forms and POST works perfectly there.

This should work:

<form style="width: 20%; margin: auto;" action="subscribe.php" method="post" id="subscribeToNews">
    <fieldset>
        <legend>Subscribe:</legend>
        <label for="subName">First Name:</label><br /><input type="text" id="subName" name="subName" /><br />
        <label for="subEmail">Email:</label><br /><input type="text" id="subEmail" name="subEmail"   /><br />
        <input style="width: inherit;" type="submit" value="Subscribe" />
    </fieldset>
</form>

<?php
$con = mysqli_connect('95.76.197.98','root','','accounts');

if($_POST) {
    $subName = mysqli_real_escape_string($con, strip_tags($_POST['subName']));
    $subEmail = mysqli_real_escape_string($con, strip_tags($_POST['subEmail']));

    if(isset($subName) && !empty($subName) && isset($subEmail) && !empty($subMail)) {
        echo 'Name: '.$subName.'<br> Email: '.$subEmail;
    }
}
?>

Nothing seems to work, so I went with form method GET and php $_GET. It works like a charm... Thanks for the struggle though, but I will go on with get, as there is no sensitive information included.
