Instead of one digit per iteration (
% 10,/ 10), print two digits at a time from a 200-byte "00".."99" table, and divide by 10000 per loop step. Output is unchanged.It's not a new idea: most of the other programming languages do this trick (Rust, Go, Java, etc.).
Numbers up to ~3 digits don't change much, but longer ones get noticeably faster:
implode()json_encode()serialize()(string)$i/echoThe C function alone is ~1.8x faster.
