What potential pitfalls can arise when trying to insert NULL values into a MySQL database using PHP?

When trying to insert NULL values into a MySQL database using PHP, a potential pitfall is not properly handling the NULL value in the query. If the NULL value is not handled correctly, it may result in errors or unexpected behavior in the database. To avoid this issue, you should explicitly set the value to NULL in the query when inserting NULL values into the database. 

// Assuming $value is the variable that may contain NULL
if ($value === null) {
    $query = "INSERT INTO table_name (column_name) VALUES (NULL)";
} else {
    $query = "INSERT INTO table_name (column_name) VALUES ('$value')";
}

// Execute the query using your database connection
mysqli_query($connection, $query);
