How can PHP be used to populate form fields with current database values for user profiles?

To populate form fields with current database values for user profiles, you can first retrieve the user's information from the database using a SELECT query. Then, you can use PHP to echo the database values into the respective form fields using the value attribute. 

<?php
// Assuming you have already established a database connection

// Retrieve user's information from the database
$user_id = $_SESSION['user_id']; // Assuming user ID is stored in a session variable
$query = "SELECT * FROM users WHERE id = $user_id";
$result = mysqli_query($connection, $query);
$user = mysqli_fetch_assoc($result);

// Populate form fields with database values
<input type="text" name="username" value="<?php echo $user['username']; ?>">
<input type="email" name="email" value="<?php echo $user['email']; ?>">
<input type="text" name="full_name" value="<?php echo $user['full_name']; ?>">
?>
