Hey,

Hi internals,

I’ve proposed a small RFC to add is_assoc_array(array $array): bool to the PHP core.

RFC: https://wiki.php.net/rfc/is_assoc_array

The function detects associative arrays using internal storage (HT_IS_PACKED). 

Similar helpers exist in frameworks, and a native version would be faster and more consistent.

No BC breaks. No impact on SAPIs or OPcache.

Feedback welcome.

Thanks,
Muhammed Arshid


What's the difference between the negation of array_is_list() and is_assoc_array()?
