Access array column by integer instead of associative key name

Question

How exactly can I apply array_column() to always get the first column of an array instead of getting the column by name?

I am seeking something like this is:

array_column($array,[0])

instead of:

array_column($array,"key");

Answer 1

Try

array_column($array, array_shift(array_keys($array)));

from Return first key of associative array in PHP

Hope can help! :)
