What are the potential risks of manually escaping special characters in SQL queries when updating database values in PHP?

Manually escaping special characters in SQL queries in PHP can lead to SQL injection vulnerabilities if not done correctly. It is recommended to use prepared statements with bound parameters to securely update database values in PHP. 

// Using prepared statements to update database values securely
$stmt = $pdo->prepare("UPDATE table_name SET column_name = :value WHERE id = :id");
$stmt->bindParam(':value', $value);
$stmt->bindParam(':id', $id);
$stmt->execute();
