I'm not sure how to explain it. Different indentation styles indent the=20
elements of an array differently when written on multiple rows. For example.
in PSR2 it is like this:
$a =3D array("a" =3D> 1,
     "b" =3D> 2,
     "c" =3D> 3);
while with Zend it is like this:
$a =3D array("a" =3D> 1,
           "b" =3D> 2,
           "c" =3D> 3);
What do you suggest?

Sorry, an error while merge my branch. all parameters are optional.

>=20
Yes is better. I rewrote as a let variable:
(process-environment
          (cons (cond
                 (num-of-workers (format "PHP_CLI_SERVER_WORKERS=3D%d" num-=
of-
workers))
                 (php-ts-mode-ws-workers (format "PHP_CLI_SERVER_WORKERS=3D=
%d"=20
php-ts-mode-ws-workers)))
                process-environment))

PHP accepts that environment variable only if > 1,=20
otherwise it issues in warning.

As I wrote to Andrea, the compilation warning seems to be caused=20
by html-ts-mode. I have prepared another patch that fixes the problem.

Thank you.
