How can reserved words and special characters in database queries be properly handled in PHP?

Reserved words and special characters in database queries can be properly handled in PHP by using prepared statements with parameterized queries. This helps to prevent SQL injection attacks and ensures that the database query is executed safely without any issues related to reserved words or special characters. 

// Example code snippet to handle reserved words and special characters in database queries using prepared statements

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

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

// Bind the parameter value to avoid SQL injection
$value = $_GET['value'];
$stmt->bindParam(':value', $value);

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

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Loop through the results
foreach ($results as $row) {
    // Process each row
    echo $row['column_name'] . '<br>';
}

// Close the database connection
$pdo = null;
