Array_column with index instead of associative key

Question

How exactly can I apply array_column always getting the first column of an array instead of getting the column by name? 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! :)
