isEmpty() public method

A value is considered empty if it is null, an empty array, or an empty string. Note that this method is different from PHP empty(). It will return false when the value is 0.

public isEmpty ( mixed $value ) : boolean
$value	mixed	the value to be checked
return	boolean	whether the value is empty

    public function isEmpty($value)
    {
        if ($this->isEmpty !== null) {
            return call_user_func($this->isEmpty, $value);
        } else {
            return $value === null || $value === [] || $value === '';
        }
    }
