How can comments in PHP code affect the occurrence of "unexpected T_String" errors?

When comments are not properly closed in PHP code, it can lead to "unexpected T_String" errors. This error occurs when the PHP parser encounters a string where it was not expected, often due to missing or improperly closed comments. To solve this issue, ensure that comments are correctly closed and do not interfere with the parsing of strings in the code.

<?php
// This is a comment
echo "Hello, World!";
?>
