Count

The count () function calculates the number of cells in an array or the number of properties in an object.

For an array, returns the number of its elements, and returns 1 for other values. Returns 0 if the argument is a variable and the variable is not defined. If mode is set to Count_recursive (or 1), the number of elements in the array in the multidimensional array is recursively computed.
