<!DOCTYPE html>
<html>
<head>
<title>
ReadingForm
</title>
</head>
<body bgcolor="Skyblue">
<h1>Submit the Entry Form</h1>
<form name="entry_form" method="post"
 enctpye="multipart/form-data" action="read_user_form.php">

So now, it’s time to read the file from the PHP script.

We have to create an php file to read the user’s send data.

file name- ReadData.php

<!DOCTYPE html>
<html>
<head>
<title>
Read User Data
</title>
</head>
<body>
    <h1>Read User Data.....</h1>
    <h3>Check Your Filling Data without validation</h3>
    <?php
    $uname=$_REQUEST["user_name"];
    $email=$_REQUEST["email_address"];
    $password=$_REQUEST["user_password"];
    echo "<b>User Name -:</b>".$uname."</br></br>";
    echo "<b>User Email Address -:</b>".$email."</br></br>";
    echo "<b>Password -:</b>".$password."</br></br>";
    echo "<b>QUALIFICATION</b></br></br>".$_REQUEST["high_school"]."</br></br>".$_REQUEST["intermediate"]."</br></br>".$_REQUEST["graduated"]."</br>";
    if(isset($_REQUEST["radio1"]))
    {
    echo "<b>Gender:--</b> ".$_REQUEST["radio1"]."</br></br>";
    }
    else
    {
        echo "<b>Gender:--</b> ".$_REQUEST["radio2"]."</br></br>";
    }
        echo "<b>Your Subjects--</b></br></br>";
       foreach($_REQUEST["subjects"] as $subject)
       {
         echo $subject."</br>";
       }
       echo "</br>End of the Script";
    ?>
    </body>
</html>
