Are there any specific security considerations to keep in mind when importing tables in PHP applications?

When importing tables in PHP applications, it is important to sanitize user input to prevent SQL injection attacks. This can be done by using prepared statements with parameterized queries to ensure that user input is properly escaped before being executed as SQL queries. 

// Example of using prepared statements to import tables securely

// Assume $conn is a valid database connection

// Sanitize user input
$tableName = mysqli_real_escape_string($conn, $_POST['tableName']);

// Prepare a statement
$stmt = $conn->prepare("SELECT * FROM ?");
$stmt->bind_param("s", $tableName);

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

// Fetch the results
$result = $stmt->get_result();

// Process the results as needed
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

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