Methods

evaluate()

evaluate(array  $database, null|int|string  $field, array  $criteria) : int

DCOUNT.

Counts the cells that contain numbers in a column of a list or database that match conditions that you specify.

The range of cells that contains the conditions you specify. You can use any range for the criteria argument, as long as it includes at least one column label and at least one cell below the column label in which you specify a condition for the column.
