Add PHP support

[atomicptr]

*.php uses C Style comments // ..., /* ... */ and comments with # ... as well. ( See also https://www.php.net/manual/en/language.basic-syntax.comments.php )

// TODO 123: Do something
$obj->doSomething();

/* TODO 123: Do something */
$obj->doSomething();

# TODO 123: Do something
$obj->doSomething();
