Anyway, you cannot use a variable inside a constant expression. But now I am simply repeating the error message. So what you need to replace this with something that can accept something dynamic. A method, for instance. — KIKO Software, Nov 03 '22 at 10:09
Just a tip, for the next time you ask a question. We don't need all 500+ lines of code, a [minimal example](https://stackoverflow.com/help/minimal-reproducible-example) would have sufficed. — KIKO Software, Nov 03 '22 at 10:11
@KIKOSoftware can you please share any refenrence how to do the method — roffy miranda, Nov 03 '22 at 10:17
Yes, see; [Classes and Objects](https://www.php.net/manual/en/language.oop5.php). A method is part of a class. It's basically a function inside your class. You need to study how classes and objects work, and what the code you're writing actually does. — KIKO Software, Nov 03 '22 at 10:22
@KIKOSoftware as right. It's a problem of understanding classes and objects. [Learn Class in PHP](https://dzone.com/articles/learn-php-how-write-class-php) — Juan, Nov 03 '22 at 10:28

You cannot use expressions (well, some are allowed, but very few) for class variable initialization. You have to use literal values.

If you want to initialize the array with dynamic values, use a constructor instead.
