Php - is it possible to count the number of keys in an array?

Question

I searched for this but did not find any answers, so I guess this is not possible. If there is a way, I would like to know. Thanks to

Array as long as its keys, you can use any of count

or sizeof

for example

echo count($your_array);

or

echo sizeof($your_array);

The number of keys in an array will always be the number of elements in the array, since the keys must be unique. So:

$numKeys = count($array);
