Details
static bool isEmpty(mixed $data)
Returns whether the given data is empty.
This logic is reused multiple times throughout the processing of a form and needs to be consistent. PHP's keyword empty cannot be used as it also considers 0 and "0" to be empty.
Parameters
| mixed | $data |
Return Value
| bool |
