What are the potential pitfalls of storing query results in variables in PHP and trying to display them in a different file?

Storing query results in variables in PHP and trying to display them in a different file can lead to issues with variable scope. To ensure that the variables are accessible in the other file, you can use sessions or pass the variables through the URL parameters. 

// File 1: storing query results in variables
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
$data = mysqli_fetch_assoc($result);

// Using sessions to pass variables to another file
session_start();
$_SESSION['data'] = $data;

// File 2: displaying the data from the session
session_start();
$data = $_SESSION['data'];
echo $data['column_name'];
