pls put all code inside a single class

pls put all code inside a single class

can I ask you what's the rationale for this? While I can see how moving parse_duration() inside a class can enhance encapsulation (did that in 2597cff), I think that exploding M3uItem into a set of methods and private variables will result in code that is harder to read, understand and maintain.

But I'm not particularly good at PHP, so maybe you have suggestions for how to keep the code well encapsulated, while having the same benefit of "all code in a single class".

php does not have modules like python does.

your previous function parse_duration was defined in global namespace.

also it's my subjective preference to have code closer together and not spread out.

i'd prefer you drop M3uItem and inline all code inside M3uFormat.

if you think this is still not right, just tell me: I'm eager to learn :)

gentle ping :)

[dvikan]

yes still thinking about this.
