What are the potential pitfalls of saving extracted data from a webpage into a database using PHP?

Potential pitfalls of saving extracted data from a webpage into a database using PHP include security vulnerabilities such as SQL injection attacks if the input data is not properly sanitized. To prevent this, it is important to use prepared statements or parameterized queries when interacting with the database to avoid SQL injection. 

// Example of using prepared statements to insert data into a database

// Assuming $conn is the database connection object
$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $data1, $data2);

// Set the values of $data1 and $data2 before executing the statement

$stmt->execute();
$stmt->close();
