PHP7.4 - error when an array is defined as a constant ()

I get this error when I define an array as a constant with php7.4.

*170 FastCGI sent in stderr: "PHP message: PHP Warning:  Use of undefined constant TIMEZONE_LIST - assumed 'TIMEZONE_LIST' (this will throw an Error in a future version of PHP) in ...

However the PHP documentation indicates that it is possible to define an array as a constant from version 7.

define('TIMEZONE_LIST',

You're correct:

  1. You should be able to [define()] an array:

https://www.php.net/manual/en/function.define.php

define(string $constant_name, mixed $value, bool $case_insensitive = false): bool

7.0.0 array values are allowed.

  1. Your syntax looks correct - I'm unable to reproduce the error.

SUGGESTIONS:

  • Check the return value from "define()".
  • Test with "var_dump()"
  • If it still doesn't work, show is the line that's generating the warning
  • Report back what you find.
