<?php
// Create a new PDO instance
$db = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare the SQL statement with placeholder
$stmt = $db->prepare('SELECT * FROM users WHERE username = :username');

// Bind the parameter value
$stmt->bindParam(':username', $username);

// Set the parameter value
$username = $_POST['username'];

// Execute the prepared statement
$stmt->execute();

// Fetch the results
$result = $stmt->fetchAll();

// Display the results
foreach($result as $row) {
    echo $row['username'] . '<br>';
}
?>
