Language Injection phpLiteralExpression with wildcard

Why do you need that?

Because I have a class with several different heredoc definations of long javascript code. It is a pain to have to manually inject JS language into each one on every edit and the default setting only recognizes <<<JS which you can only use once in a file.  Having it also automatically inject <<<JS2... <<JSfoo would be great. Is there a better way I can be doing this?

the default setting only recognizes <<<JS which you can only use once in a file.

New to me -- did not know that. Can you point me to a official documentation which states this limitation?

Why this works just fine then?

<php
$zz = <<<JS
var meow = 125;
JS;

echo $zz, "\n";

$zz = <<<JS
alert('Hello!');
JS;

echo $zz, "\n";

Not sure where I got that. You are right though. Thanks!
