PHP FilterIterator Example

This abstract iterator filters out unwanted values. This class should be extended to implement custom iterator filters. The FilterIterator::accept() must be implemented in the subclass.

In accept()method we will apply logic on whatever $this->current() method will return as shown below. In the below method we are testing against current element is active or not , depending on the response we are returning a Boolean true or false. If the result is false that element will be removed form the result and vice versa.
