Availability
- Compiled (AOT): supported by the Elephc code generator.
eval()(magician interpreter): supported — declarative interpreter builtin (crates/elephc-magician/src/interpreter/builtins/raw_memory/buffer_len.rs).- Strict PHP mode: hidden — this builtin is an elephc extension with no PHP equivalent, so programs compiled with
--strict-phptreat the name as nonexistent, in compiled code and inside eval’d code.
