embed sapi unable to load tokenizer, undefined symbol zend_ce_stringable

Description

Experimenting with the sample embed sapi code and build instructions from the provided readme. I also have the tokenizer extension installed. The php cli sapi works just fine. And php -m reports the tokenizer extension loaded. However, the embed sapi throws a warning about being unable to load tokenizer due to an undefined symbol, zend_ce_stringable. I suspect other extensions that utilize this class will also fail to load in the same way.

Any ideas what am I missing here? This might not be a bug (apologies if not), but I'm just not seeing what isn't being loaded to make tokenizer happy. Feels like a bug or a documentation oversight. Will poke at it some more tomorrow.

先从示例 embed SAPI 代码和提供的 README/build 说明开始，然后比较 embed SAPI 和 CLI 加载 tokenizer 扩展的方式。确认未定义符号是由 embed build 还是由扩展加载导致的，并在 tokenizer 加载时不再出现警告，或文档说明了所需的设置后，将该 issue 视为已解决。
