Freshly installed phpfastcache via composer, attempting to use an unmodified (sans require path) leveldb example produces the error:

To Reproduce
Steps to reproduce the behavior:

1. Create a new directory on a publicly accessible website.
2. In that directory, composer require phpfastcache/phpfastcache (respond 'n' if asked to use a parent directory composer.json)
3. Create index.php with the contents of docs/examples/leveldb.php.
   3.a. Modify index.php to adjust the include path to point to the vendor folder composer created.
4. Access that directory through a web browser.
5. Observe 500 error.
6. View server error logs, observe error similar to one shown above.

Expected behavior
The leveldb example to run.

Additional context
I'm not sure if this is something fixed in v9. I'm not on PHP 8 yet, so I can't try the newer version.

Hello,

Example directory is not really reliable but I'll push a fix soon.

Be aware that this directory has been removed in V9.

Instead look at the tests directory which contain much more reliable examples.

Sure that makes sense! :)

I don't see any test that uses the leveldb driver specifically. But I am still confused as to where the htaccess issue is coming from, too. I don't see that property in the config structure for it to get upset about. The same code seems to work fine if I swap the leveldb driver for files for example.

[Geolim4]

This issue has been fixed, however I'm not going to make a new version immediately, meanwhile use dev-v8.

[nitz]

Awesome, thank you! I'm blown away with how quickly you responded and got this figured out. Make sure to relax some this weekend! :)

It's because Phpfastcache "auto-validate" the Configuration object passed to the driver pool instance, if something is wrong it throws an error.

I think this driver is not tested actually (the last one not to be) because I can't build a stable Leveldb extension for current php7 version. It looks abandoned or poorly maintained atm.
