允许登录用户编辑其信息 - PHP / MySQL

Question

I apologise if this question has been asked, I have looked and can't find an answer that fits but if I'm wrong please tell me!

I've created a login form and when the user logs in they can see their Name, E-mail, Phone and Availability. At the moment this is just echoing / printing the information from the MySQL database. What I was wondering is how I make this editable so that the logged in user can update their own information?

Thanks an absolute bunch to everyone by the way, I'm new to this site and everyone has been extremely helpful. I'm not a developer by trade and very much learning as I go on this project so it is appreciated! :)

<?php
session_start();
$sessData = !empty($_SESSION['sessData'])?$_SESSION['sessData']:'';
if(!empty($sessData['status']['msg'])){
$statusMsg = $sessData['status']['msg'];
$statusMsgType = $sessData['status']['type'];
unset($_SESSION['sessData']['status']);
}
?>
<div class="container">
<?php
    if(!empty($sessData['userLoggedIn']) && !empty($sessData['userID'])){
        include 'user.php';
        $user = new User();
        $conditions['where'] = array(
            'id' => $sessData['userID'],
        );
        $conditions['return_type'] = 'single';
        $userData = $user->getRows($conditions);
?>
<h2>Welcome <?php echo $userData['first_name']; ?>!</h2>
<a href="userAccount.php?logoutSubmit=1" class="logout">Logout</a>
<div class="regisFrm">

    <p><b>Phone: </b><?php echo $userData['phone']; ?></p>

    <p>Don't have an account? <a href="registration.php">Register</a></p>
</div>
<?php } ?>
</div>

I am a newbie to php programming as well, so I very well could be wrong. I apologize in advance if this doesn't work. From what I understand of your question, why can't you make a form? I was in a similar situation before, and I just made a form asking for their details they wish to change and a password field. Transfer the data from the form to a .php file (using action='filename.php'), where you can make queries to update your mysql database.

Hope it helps.
