Hi so i am a beginner and i am  trying to submit a very basic form in a  php file.
THE Problem :
Upon entering a name and pressing the submit button, it redirects me to a window which asks me to save the file locally
Image of Save file locally window
Instead of giving output as: HI (name_entered)
MY code
<?php
if(isset($_GET["name"])){
   echo"HI". $_GET["name"];
    exit();
}
?>
<html>
    <body>
        <form action = "<?php $_PHP_SELF ?>" method="GET">
    Name:<input type="text" name="name" />
    <input type="submit"/>
    </form>
</body>
</html>
I have been trying to solve this for quite some time ... can someone please tell me where i am going wrong
