How to get user input and apped to the URL in PHP?

Question

I want to create a simple PHP website were user should enter any string in text box and click submit then that string should be placed in the URL

For example:

If user entered "Java" as their input then after clicking submit, the URL should change to:

example.com/Java

How it's possible any example or a sample program if possible

Answer 1

Well, taking your question literally, this should work

<?php
    if(isset($_POST['submit'])){
        $userInput = $_POST['userInput'];
        header('Location:example.com/'.$userInput);
    }
?>
<form action="" method="POST">
    <input type="text" name="userInput"/>
    <input type="submit" name="submit" value="Send"/>
</form>

Of course, depending on your codes, this might be used to tamper or do something bad to your codes.
