Availability
- Compiled (AOT): supported on the three executable/release hosts (macOS ARM64, Linux ARM64, and Linux x86_64); calls are refused at compile time for iOS library targets.
eval()(magician interpreter): supported — declarative interpreter builtin (crates/elephc-magician/src/interpreter/builtins/pcntl/pcntl_daemon.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.
No examples yet — check examples/ and showcases/ for usage patterns.
