Sind mit mysqli_escape_string alle potenziellen Injection-Angriffe abgewehrt, oder gibt es weitere Schutzmaßnahmen, die ergriffen werden sollten?

mysqli_escape_string is a good first step in protecting against SQL injection attacks by escaping special characters in a string before sending it to the database. However, it is not foolproof and additional measures should be taken, such as using prepared statements with parameterized queries to further prevent injection attacks. 

// Using mysqli_escape_string to escape special characters
$unsafe_variable = $_POST['input'];
$safe_variable = mysqli_escape_string($connection, $unsafe_variable);

// Using prepared statements with parameterized queries
$stmt = $connection->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $safe_variable);
$stmt->execute();
$result = $stmt->get_result();
