<body bgcolor="Skyblue">
<h1>Submit the Entry Form</h1>
<form name="entry_form" method="post"
 enctpye="multipart/form-data" action="read_user_form.php">
 Full Name : <input type="text" name="user_name"
 placeholder="Full Name"></br></br>

<!DOCTYPE html>
Read User Data
    <h1>Read User Data.....</h1>
    <h3>Check Your Filling Data without validation</h3>
    echo "<b>User Name -:</b>".$uname."</br></br>";

    echo "<b>QUALIFICATION</b></br></br>".$_REQUEST["high_school"]."</br></br>".$_REQUEST["intermediate"]."</br></br>".$_REQUEST["graduated"]."</br>";
    echo "<b>Gender:--</b> ".$_REQUEST["radio1"]."</br></br>";
        echo "<b>Gender:--</b> ".$_REQUEST["radio2"]."</br></br>";
        echo "<b>Your Subjects--</b></br></br>";
       foreach($_REQUEST["subjects"] as $subject)
