… fields (#20105) `tmp` can only ever be non-undef if there's a hooked object property, which is already an `UNEXPECTED()` case. Keep track of whether this case is hit or not to avoid needlessly calling `zval_ptr_dtor()`. For: <?php $len = 0; for ($i = 0; $i < 3_000_000; $i++) { $len += strlen(json_encode(array_fill(0, 20, []))); } var_dump($len); This is ~1.02 faster for a gcc 13.3 release build on a Intel(R) Core(TM) i7-1365U. Benchmark 1: /tmp/bench/before /tmp/bench/test6.php Time (mean ± σ): 762.7 ms ± 3.2 ms [User: 758.5 ms, System: 2.8 ms] Range (min … max): 759.2 ms … 769.3 ms 10 runs Benchmark 2: /tmp/bench/after /tmp/bench/test6.php Time (mean ± σ): 748.3 ms ± 9.0 ms [User: 744.3 ms, System: 3.1 ms] Range (min … max): 740.8 ms … 766.2 ms 10 runs Summary /tmp/bench/after /tmp/bench/test6.php ran 1.02 ± 0.01 times faster than /tmp/bench/before /tmp/bench/test6.php
