Cycling through a list ( array ) of strings is a common need. Particularly when you want to flip flop through colors on table rows. Rather than custom program the logic in every script I run I encapsulated it in a simple class. The class name is “cycle”.
The class has three methods:
- load: This function takes a string and adds it to its internal list
- getNext: returns the next string on the list and returns the first string if at the end of the list.
- reset_pointer: sets getNext to return the first string on the list.
The code is for php5.

- Just download the class
Feel free to use it, extend it, or mock it often. :-)
