How does saving a file in UTF-8 format without a BOM affect PHP code execution?

Saving a file in UTF-8 format without a BOM can cause issues with PHP code execution, as the absence of a BOM (Byte Order Mark) can lead to encoding problems. To ensure proper execution, it is recommended to include a BOM at the beginning of the file when saving it in UTF-8 format. 

<?php
// Add BOM to ensure proper UTF-8 encoding
$fileContent = "\xEF\xBB\xBF" . file_get_contents('your_file.php');
file_put_contents('your_file.php', $fileContent);
?>
