[php-src] Issue #7993: php open/close tags igored within C-style comments

Issue: https://github.com/php/php-src/issues/7993 Author: Daniel-Peder ### Description [The following code: ```php <?php echo (ob_start()?'':'') . /* ?> hello world <?php */ ob_get_clean() , PHP_EOL ; ``` Resulted in this output: ``` ``` But I expected this output instead: ``` hello world ``` ](https://3v4l.org/OkFOE) The open/close tags <?php ... ?> should have precedence over the comments or at least, it should be better described in manual page. According to the [php tags manual page](https://www.php.net/manual/en/language.basic-syntax.phptags.php), telling: > When PHP parses a file, it looks for opening and closing tags, which are <?php and ?> > which tell PHP to start and stop interpreting the code between them. PHP does not obey this rule, as it rather considers the text between tags as part of comment, which is, however, rather part of interpreted php code instead of part of not interpreted text. ### PHP Version ALL ### Operating System _No response_
