[GLD Serializer Benchmark] PHP json 8.3.19 — spec compliance misses

从 PHP json 的 GLD Serializer Benchmark 合规性仪表板开始，然后打开每个已评分的 FAIL 并阅读其中引用的规范段落。复现报告中的编码器或解码器行为，并确定每个未通过项是真正的 bug，还是有意记录在案的默认行为；完成的标准是问题已通过适当的覆盖得到修复，或已明确记录为有意行为。

Hi — this is a friendly report from the GLD Serializer Benchmark, an independent multi-language suite that times serializers and checks them against the published format specs (RFC 8259, YAML 1.2, …).

We measured json 8.3.19 on PHP. The suite recorded spec-profile misses for this pin. The catalog is report-only: a miss is not a CI failure, and some cases are older or stricter profiles (for example RFC 4627 vs RFC 8259) rather than a crash.

Compliance results (please start here)

This link opens the live heatmap on PHP with json already selected (All standards). Click a scored cell for each FAIL and the cited spec paragraph:

How the catalog is built, and how to read a FAIL line:

• https://leo-gan.github.io/GLD.SerializerBenchmark/compliance/
• https://leo-gan.github.io/GLD.SerializerBenchmark/compliance/reading-results/

I am not pasting the case list here so you can use the Dashboard (filters, heatmap, and spec links) rather than a static dump.

Optional: one standard family only — #compliance/php/json/json (or yaml, cbor, …).

Benchmark timings (same pin)

The same suite also publishes encode / decode time and payload size for this library on PHP:

Details table (this library pre-selected):

https://leo-gan.github.io/GLD.SerializerBenchmark/dashboard/?lang=php&ser=json&data=document@n=1&mode=bytes#detailed-analytics

That page is the live L1 snapshot, not a claim that one library is “best.”

Ask

Please look at the Compliance view for json. If a miss is a real decoder/encoder bug you want to fix, great. If it is an intentional default (accepting NaN, YAML 1.1 bools, …), a short note here is enough — we will keep the catalog as-is unless the library’s documented contract changes.

Thanks for the library.
