How can variables in PHP scripts be named to avoid conflicts with session variables and prevent errors like the session side-effect warning?

To avoid conflicts with session variables and prevent errors like the session side-effect warning, variables in PHP scripts can be named with a prefix or naming convention that clearly distinguishes them from session variables. This can help prevent accidental overwriting of session variables and ensure that each variable serves its intended purpose without causing conflicts. 

// Prefix all variable names with "my_" to avoid conflicts with session variables
$my_variable = "example";

// Access session variables using the $_SESSION superglobal
$_SESSION['session_variable'] = "session_example";
