@heyanlong This is for license check for PHP, welcome to provide feedback.

@emschu hey, thanks for bringing this up.

Is it allowed to have multiple <?php ... ?> in a single .php file, in another word, is the following codes are valid in PHP?

<?php
/**
 * header license comments
 */
?>

<?php
// some real codes
?>

If it's valid, maybe we can simple use the following comment style config,

- id: PHP
  start: |
    <?php
    /*
  middle: ' *'
  end: |
    */
    ?>

multi-line strings in yaml is rather legit and normal.

@kezhenxu94 Yes, your example is a valid php script syntax. You can read about this topic here.

If a file contains only PHP code, it is preferable to omit the PHP closing tag at the end of the file. This prevents accidental whitespace or new lines being added after the PHP closing tag, which may cause unwanted effects because PHP will start output buffering when there is no intention from the programmer to send any output at that point in the script.

For this reason I think it is not a good idea to generally add a php closing tag after the license header in PHP files as this could cause trouble with whitespace or output buffering in pure php files (pure means: non-template PHP code, e.g. class definitions etc.).

I will think about this problem next week again. Enjoy the weekend!
