I have two .php files as such:
test1.php
<html>
<head>
<title>Sample</title>
</head>
<body>
<form action="test2.php" method="post">
Please enter a number <input type="number" name="userNumber"><br>
<input type="submit">
</form>
</body>
</html>
test2.php
<html>
<head>
<title>Sample Display Page</title>
</head>
<body>
<?php
$user_number = $_POST["userNumber"];
echo "You have chosen $user_number";
?>
</body>
</html>
I want to know how can I get it all to display on a single page, i.e. on the test1.php, without having to have two files.
