What potential issues could arise when updating a database using PHP scripts?

One potential issue that could arise when updating a database using PHP scripts is SQL injection attacks. To prevent this, you should always use prepared statements with parameterized queries to sanitize user input. 

// Using prepared statements to update a database record
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$stmt = $pdo->prepare('UPDATE users SET email = :email WHERE id = :id');
$stmt->bindParam(':email', $email);
$stmt->bindParam(':id', $id);
$stmt->execute();
