The choice of text editor can impact the functionality of PHP code, particularly when dealing with session variables, due to issues like incorrect syntax highlighting or auto-formatting. To ensure proper functionality, it's important to use a text editor that properly supports PHP syntax and doesn't interfere with session variable handling. 

<?php
session_start();

// Accessing session variables
$_SESSION['username'] = 'JohnDoe';
