How to load sqlite extension in PDO?

Question

First, I want to inform about the case to avoid the misunderstanding.

By sqlite extension, I mention Sqlite\'s extension like FTS, not PHP\'s sqlite extension.

Answer 1

No way present now except workaround mentioned above. If you would want to check progress somewhere in the future, there's an issue on PHP bugtracker.

Answer 2

I have implemented a library with a solution for this problem for PHP 7.4+ which does not involve recompiling the PDO driver. In short, it uses PHP's FFI extension and Z-Engine (which reads PHP's internal memory structures using FFI) to make a direct call to the SQLite C API. You can find more detailed background information in this blog post. I would not recommend this solution in production yet, but it could be a feasible workaround for test or development workflows.

Answer 3

could not find a compiler flag and we have solved it with a quick'n dirty hack in pdo_sqlite extension. patched sqlite_driver.c with sqlite3_enable_load_extension() from sqlite3 API.
