Cache info compatibility with APCu

[damienalexandre]

From what I read in the code, this tool is not compatible with APCu.

Env

• PHP Version 7.0.7
• APC Compatibility 1.0.3
• APCu Version 5.1.4
• cachetool 2.0.6 (because I use Symfony 2) but master have the same issue

The issue

The apc:cache:info command fails:

$ ./bin/cachetool apc:cache:info --fcgi=/var/run/php-fpm.sock

Fatal error: Uncaught TypeError: Argument 1 passed to CacheTool\Command\ApcCacheInfoCommand::normalize() must be of the type array, null given, called in vendor/gordalina/cachetool/src/CacheTool/Command/ApcCacheInfoCommand.php on line 60 and defined in vendor/gordalina/cachetool/src/CacheTool/Command/ApcCacheInfoCommand.php:101

This is because this statement return null:

$this->getCacheTool()->apc_cache_info('system');

I'm not sure why exactly but the fact is that signatures for this method are different between APC and APCu, but the CacheTool always tries to call the old signature.

        $code->addStatement(sprintf(
            'return apc_cache_info(%s, %s);',
            var_export($cache_type, true),
            var_export($limited, true)
        ));

As the command expect both a "user" and a "system" cache infos from APC, maybe it should be fixed with a new command apcu:cache:info, because APCu only expose user cache. WDYT?

APCu

http://php.net/manual/fr/function.apcu-cache-info.php

array apcu_cache_info ([ bool $limited = false ] )

APC

http://php.net/manual/en/function.apc-cache-info.php

array apc_cache_info ([ string $cache_type = "" [, bool $limited = false ]] )

Ok blames on me, there is already a nice PR about this: #36

Someone should open again this PR as the fix of #36 did not solve the issue. I downloaded the 2.1.0 and the bug is still there.

With the changes in #36 you have to call apcu:cache:info for it to work, and not apc:cache:info as I assume you did?
