How can prepared statements in PHP, like those offered by ADODB, help mitigate issues related to special characters and data integrity when interacting with a database?

Prepared statements in PHP, like those offered by ADODB, help mitigate issues related to special characters and data integrity by automatically escaping input data, preventing SQL injection attacks, and ensuring proper handling of special characters. This helps to protect the database from malicious input and ensures that data integrity is maintained during interactions with the database. 

// Example of using prepared statements with ADODB to prevent SQL injection attacks and handle special characters

// Connect to the database using ADODB
$db = NewADOConnection('mysqli');
$db->Connect('localhost', 'username', 'password', 'database');

// Prepare a SQL query with placeholders for input data
$stmt = $db->Prepare("INSERT INTO users (username, email) VALUES (?, ?)");

// Bind input data to the placeholders
$username = "John Doe";
$email = "johndoe@example.com";
$stmt->Execute(array($username, $email));
