Are there any potential pitfalls to be aware of when manipulating data between MySQL tables in PHP?

One potential pitfall when manipulating data between MySQL tables in PHP is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, always use prepared statements with parameterized queries to securely interact with the database. 

// 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 and execute the statement
$stmt->bind_param("ss", $value1, $value2);
$value1 = "example";
$value2 = "data";
$stmt->execute();

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