What are some common pitfalls when trying to access and display variables between different PHP files in a WordPress environment?

One common pitfall when trying to access and display variables between different PHP files in a WordPress environment is variable scope. To solve this issue, you can use global variables or WordPress functions like `get_option()` to retrieve and display variables across different files. 

// In the first PHP file
$my_variable = 'Hello, World!';
update_option('my_variable_option', $my_variable);

// In the second PHP file
$retrieved_variable = get_option('my_variable_option');
echo $retrieved_variable;
