关于数组，计数，大小OR？

Question

I'm triyng to get a count from array like below

CASE 1
Array ( [0] => [1] => [2] => [3] => [4] => [5] => )

CASE 2
Array ( [0] => name [1] => telephone [2] => [3] => [4] => [5] => )

If I use COUNT, results is 5
echo count($array);

I'm like to get 0 (in case 1) and 2 (in case 2)

Exist a way to do this?

Answer 1

Use this:

$remove_empty = array_filter($your_array);  
print_r($remove_empty);
