I have a simple array like so :
stdClass Object
[
[Colors] => Array
[
[0] => stdClass Object
[
[value] => Blue
]
]
[Sizes] => Array
[
[0] => stdClass Object
[
[value] => 10
]
[1] => stdClass Object
[
[value] => 30
]
]
]
then I just want to count array keys [Colors] and [Sizes], which should give me 2 in total, but using count[] like count[$array], throws "Warning: count[]: Parameter must be an array or an object that implements Countable"

Assuming your variable is $obj
count[get_object_vars[$obj]];
// return 2, for your object variables are two: Colors & Sizes [both arrays]
count[$obj->Colors];
// return 1, for your object variable [Colors] [which is array] has only one element
count[$obj->Sizes];
// return 2, for your object variable [Sizes] [which is array] has two elements
count[get_object_vars[$obj->Sizes[0]]];
// return 1, for your object variable[Size]'s [0] index has only 1 object element, i.e. 10

I couldn't find a function for counting the values with case-insensitive matching, so I wrote a quick and dirty solution myself:
This prints:
Array
[
[J. Karjalainen] => 3
[60] => 2
[j. karjalainen] => 1
[Fastway] => 2
[FASTWAY] => 1
[fastway] => 1
[YUP] => 1
]
Array
[
[J. Karjalainen] => 4
[60] => 2
[Fastway] => 4
[YUP] => 1
]
I don't know how efficient it is, but it seems to work. Needed this function in one of my scripts and thought I would share it.

array_count_values function does not work on multidimentional arrays.
If $score[][] is a bidimentional array, the command
"array_count_values [$score]" return the error message "Warning: Can only count STRING and INTEGER values!".
