 Replying to [comment:102 nextendweb]:
 > Well, if {{{.phtml}}} won't get included, I will be able to rename the
 files in Smart Slider 3. {{{.phtml}}} files are popular in the Magento
 community. I thought there is wider usage in the repos.

 That's great, thank you -- and sorry for the difficulty. Let's see what
 the PHP team says, too.

 Thanks!! I think I figured out what's going on with it from the command
 line, and am working on + testing a patch to change `__DIR__` to
 `realpath( $_SERVER['SCRIPT_FILENAME'] )` now. Here's my current
 understanding:

 PHP compares with `opcache.restrict_api` with `PATH_TRANSLATED`
 [https://github.com/php/php-
 src/blob/master/ext/opcache/zend_accelerator_module.c#L56]. This can be
 different than the included file, which is returned by `__FILE__`.

 However, `$_SERVER['PATH_TRANSLATED']` is
 [https://www.php.net/manual/en/reserved.variables.server.php not always
 available directly].

 So far, `$_SERVER['SCRIPT_FILENAME']` seems to most closely approximate
 this, but `realpath()` is necessary because
 [https://www.php.net/manual/en/reserved.variables.server.php
 `SCRIPT_FILENAME` can be a relative path on the command line].

 I would love to hear if there is a better way to get the `PATH_TRANSLATED`
 that is used.
