Enum case value must be compile-time evaluatable¶
Description¶
The value of a backed enumeration, string or integer, cannot be build with constant (global or classe). It can only be build with literal values.
This limitation was removed in PHP 8.2.
Example¶
<?php
enum Foo: string {
case A = '/' . A;
case B = '/' . __FILE__;
}
?>
Solutions¶
Upgrade to PHP 8.2.
Replace the constants with literal values.
