What security considerations should be taken into account when using PHP scripts to interact with MySQL databases for data import tasks?

When using PHP scripts to interact with MySQL databases for data import tasks, it is important to consider security measures to prevent SQL injection attacks. One way to mitigate this risk is to use prepared statements with parameterized queries, which can help sanitize user input and prevent malicious code execution. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Prepare a SQL statement with a parameterized query
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");

// Bind parameters to the query
$stmt->bind_param("ss", $value1, $value2);

// Set parameter values
$value1 = "input_value1";
$value2 = "input_value2";

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

// Close the statement and database connection
$stmt->close();
$mysqli->close();
