Hello, again:

In the original post I was trying to apply anonymous code to a static
member array.

            self::$_runList[$_what] = $_code;
$_out = self::$_runList[$_what]($_params); // >>> line # 27
referred to in error message

What is now working is to use a locally declared array inside run()
instead:

$_runList = array()
$_runList[$_what] = $_code;
return $_runList[$_what]($_params);

Apparently, php doesn't like doing this with a static member array
variable.

Thanks to anyone who spent some time with the original post.

You appear to be using a 5.x version of PHP. This is an associativity
problem and can be resolved by upgrading to PHP7. Here is your original code, you can see it works in PHP7, and produces and notice followed by a
fatal error in PHP<7  https://3v4l.org/Zu1jO For more information, see
http://php.net/manual/en/migration70.incompatible.php#migration70.incompatible.variable-handling.indirect

I have also been testing out the use of non static member variable array referenced via $this-> that is working. The non static member array appears to be retaining the code that is assigned to it, as I can call it again in a subsequent call and it runs as expected, using the original array key string assigned to it.
