Why won’t my code work? (HTML)

Question

I have a set of HTML code for a Messaging app. I wanted to export the message data as an array, but on the webpage (input page) it shows the code instead of running it, can anybody tell me what is wrong with it?

<?DOCTYPE html>
<form action="first.php" method="post">
<p>Name: <input type="text" name="Name" /></p>
<p>Message: <input type="text" name="Message" /></p>
<p>Time: <input type="text" name="Time: " /></p>
<p><input type="submit" name="submit" value="Submit" /></p>
</form>
<?php
$array = [
"Name" => .$_GET['Name'],
"Message" => .$_GET['Message'],
"Time" => .$_GET['Time']
];
?>
file_put_contents('Chat.txt', print_r($array, true));

Answer 1

i am pretty sure mg PHP is outside the HTML, the last HTML tag is </form> and then it shows the php tag

Answer 2

You are using post method but in the code but you have $_GET. Use $_POST instead

Answer 3

i though the $_GET got the value of input text...

Answer 4

also, i tried that, it still shows the code as text ln the website...
