What precautions should be taken when using prepared statements in PHP to prevent errors or unexpected behavior?

When using prepared statements in PHP, it is important to properly bind parameters to prevent SQL injection attacks and ensure data integrity. Additionally, make sure to handle errors that may occur during the execution of the prepared statement to prevent unexpected behavior. 

// Example of using prepared statements in PHP with error handling
$stmt = $pdo->prepare("SELECT * FROM users WHERE email = :email");
if ($stmt) {
    $stmt->bindParam(':email', $email);
    if ($stmt->execute()) {
        // Process results
    } else {
        // Handle execution error
        echo "Error executing statement";
    }
} else {
    // Handle prepare error
    echo "Error preparing statement";
}
