What are the potential pitfalls of using outdated methods, such as renaming files, to work with PHP files in modern Windows operating systems?

Using outdated methods like renaming files to work with PHP files in modern Windows operating systems can lead to compatibility issues and potential errors in the code. It is recommended to use proper file handling functions provided by PHP, such as fopen, fwrite, and fclose, to ensure smooth operation and avoid any unexpected behavior.

// Example of using proper file handling functions in PHP
$file = fopen("example.txt", "w") or die("Unable to open file!");
$txt = "Hello, World!";
fwrite($file, $txt);
fclose($file);
