A technique where attackers can inject malicious SQL commands into SQL statements is called code example
Example: sql injection attack
$value = "your value here";
try {
$pdo = new PDO($dsn, $username, $password, $>drivers);
} catch (\PDOException $e) {
echo 'Connection Failed: ' . $e->getMessage();
}
$sql = "INSERT INTO `my_db` SET `field` = ? ";
$stmt = $this->pdo->prepare($sql);
$stmt->bindValue(1, $value, PDO::PARAM_STR);
$stmt->execute();
$stmt = null;
