What role does the Internet Explorer browser play in causing encoding issues with PHP variables and session data?

Internet Explorer browser can cause encoding issues with PHP variables and session data when it sends requests with different character encodings than expected. To solve this issue, you can set the default character encoding for PHP files to ensure consistent handling of data across different browsers. 

// Set default character encoding to UTF-8 in PHP
header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');
