How to show contact details while clicking the particular name from <li> list

Contact_list.php:

<?php 
    $con=mysqli_connect("localhost","user","pass","nilambu1_mydb"); 
    // Check connection 
    if (mysqli_connect_errno()) { 
        echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 

    $result = mysqli_query($con,"SELECT * FROM n_info "); 

    while($row = mysqli_fetch_array($result)) { 
        echo "<li><a href='contact.php' data-transition='slidedown'> <img src='images/calling.png'/> <h2> " . $row['first_name'] . " " . $row['last_name'] . "</h2> <p >Mobile : " . $row['mobile1'] . "  ,  " . $row['mobile2'] . "</p></a></li>"; 
    }

    mysqli_close($con);

?>

viewcontact.php:

I have contact book in my SQL database. After my basic coding I got contact name via <li> list.

My html output:
