    Here's the working code. But learn the basics first.

    index.html

    <!DOCTYPE html>
    <html>
    <head>
        <title>Index page</title>
    </head>
    
    <body>
    
    <form method="POST" action="retrieve.php">
    
        Enter your name : <input type="text" name='username'><br><br>
        <input type="submit" name="submit">
    
    </form>
    
    </body>
    </html>
    

    retrieve.php

    <?php
    
    //Database connection
    $connection = mysqli_connect("localhost","username","password","database_name");
    
    if (isset($_POST['submit'])) {
    
        $uname = $_POST['username'];
    
        // sql query and user is the table name
        $query = "SELECT * FROM `user` WHERE user_name='$uname'";
    
        // query to execute
        $result = mysqli_query($connection,$query);
    
        if (!$result) {
            echo "fails";
        }
    
    
        while($row = mysqli_fetch_array($result)) {
    
            $telephone_no = $row['phoneno'];
            $country_name = $row['country'];
    
            echo "Your results for name - " . $uname;
            echo "<br><br>";
    
            echo "Telelephone is : " . $telephone_no;
            echo "<br>";
            echo "Country name is : " . $country_name;   
        }  
    }
    ?>
    

    Database structure : (User table)

    enter image description here

    To test the code, insert a person details in PHPMyadmin insert tab.(Leave id alone as it was set to an auto-increment).
