array_merge(): Argument #1 is not an array #37

Closed df1paw closed 5 years ago

Hi.

I currently experience the following error: Warning: array_merge(): Argument #1 is not an array in /homepages/[....]/opcache.php on line 198

And no data is shown on the dashboard

Any ideas?

Kind regards, Andreas

Hi, thanks for getting in touch.

It sounds like it can't get some of the information required from opcache, or it's not coming back as an array. If you check the values (var_dump them or something) for $status['memory_usage'] and $status['opcache_statistics'] just before the $overview = array_merge( line then you should see if you're actually getting any info back. Depending on what that is it may affect how you handle things.

Same error at my site. $status['memory_usage'] and $status['opcache_statistics'] are NULL.

I think it's Apache/PHP configuration issue not the script.

> php --ri 'Zend OPcache'

Zend OPcache

Opcode Caching => Up and Running
Optimization => Enabled
SHM Cache => Disabled
File Cache => Enabled
Startup => OK

When I dump opcache_get_status() I'm getting: ["opcache_enabled"]=> bool(false) The problem appeared just after switching from PHP5.6 to PHP7.2.

Thanks for the detailed feedback! This script should handle these kinds of issues without throwing errors, so I'll look into it soon.

Hi. I'm using the latest version from here. I just changed opcache.file_cache_only=1; to =0 in my php.ini -> seems to work now ;-)

Just checked what df1paw found and I can confirm it. It's working when "file cache only" option is disabled. So this is only workaround not final solution.

amnuts commented 5 years ago

Unfortunately, the opcache_get_statistics returns very, very little information when the file_cache_only setting it 1, which leaves the gui basically just displaying the opcache settings and the links to the functions. If this ever changes then I'll update the code, but there's little I can do with this right now other than making it not break if you have the setting to 1.

Sorry it took a while!
