Req #81241 [Opn]: quoted strings should support "{$this::constant}"

Edit report at https://bugs.php.net/bug.php?id=81241&edit=1 ID: 81241 Updated by: nikic@php.net Reported by: divinity76 at gmail dot com Summary: quoted strings should support "{$this::constant}" Status: Open Type: Feature/Change Request Package: Scripting Engine problem PHP Version: Next Minor Version Block user comment: N Private report: N New Comment: The current limitation here is that that it start's with {$ and the contents of {} are a "variable". Class constants aren't considered a variable. This could be relaxed in two ways: * Specifically allow class constants in addition to variables. * Allow any expression (subject to the limitation that it must start with $). This would also make something like "{$a + $b}" valid, but not "{1 + $a}". Both are backwards compatible, in that they only allow things that were previously a syntax error. This is unlike the case where "{any expression}" is allowed, which would be a major break. In any case, such a change would need an RFC.
