ob_implicit_flush() — internals

Where it lives

• Signature: src/builtins/io/ob_implicit_flush.rs
• Lowering: src/codegen/lower_inst/builtins/output_buffering.rs:474 (lower_ob_implicit_flush)
• Function symbol: lower_ob_implicit_flush()

Lowering notes

• Lowers ob_implicit_flush([$enable]): store the flag (semantically inert in
• elephc — terminal writes are unbuffered syscalls) and return true like PHP 8.

Runtime helpers

No direct __rt_* helpers captured — the lowering is inlined or routes through another builtin.
