I got a PHP object which can be an array or not.

I'd like to check not only that it's an array (which can be indexed by strings) but that it's an array of the form [x_1, x_2, x_3 ...].

Therefore the function is_array doesn't suit me.

But what instead?

Please share what you've tried so far – Haridarshan Jun 11 '21 at 11:37
There are several ways to do it. I'm looking for the most concise/professional. – mcoulont Jun 11 '21 at 11:39
Show at least one way that you've tried. – u_mulder Jun 11 '21 at 11:54
Yes it does RickN. So I guess that PHP has no built-in function for this. – mcoulont Jun 11 '21 at 13:19
