What are the best practices for handling special characters and formatting in PHP when dealing with database values?

Special characters and formatting in database values can cause issues when retrieving or storing data in PHP. To handle this, it's important to properly escape special characters to prevent SQL injection attacks and ensure data integrity. Use prepared statements with parameterized queries to safely interact with the database and handle special characters like quotes, slashes, and other potentially harmful characters. 

// Example of using prepared statements to handle special characters and formatting in PHP

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM my_table WHERE column_name = :value");

// Bind the parameter value
$value = $_POST['input_value']; // Assuming user input
$stmt->bindParam(':value', $value);

// Execute the query
$stmt->execute();

// Fetch data
$result = $stmt->fetch(PDO::FETCH_ASSOC);

// Use the fetched data
echo $result['column_name'];
