Why is it recommended to omit the ?> at the end of code-only files in PHP?
It is recommended to omit the ?> at the end of code-only files in PHP to prevent any accidental white space or characters being output after the closing tag, which could cause issues such as headers already sent errors. By omitting the closing tag, you ensure that the PHP parser will not output anything beyond what is intended in the code.
<?php
// Your PHP code here
// No closing tag at the end of the file
