What are potential pitfalls when trying to copy website content to a MySQL database using PHP?

One potential pitfall when copying website content to a MySQL database using PHP is not properly sanitizing the input data, which can lead to SQL injection attacks. To solve this issue, always use prepared statements with parameterized queries to ensure the data is properly escaped before being inserted into the database. 

// Establish a database connection
$mysqli = new mysqli("localhost", "username", "password", "database");

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

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

// Set the values of the parameters
$value1 = $_POST['input1'];
$value2 = $_POST['input2'];

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

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