Custom sorting arrays in PHP

Hi everyone

I hope you can help.

I need to do something that I think is quite simple but I'm having problems doing it.

What I want to do is use a sort function to sort data on length, but I can't find a function to do it, is there one?

Basically I have a list of words and I want to sort them with the longest word first and the shortest word last. Is there a function to do this?

If there's not like I think than how can I do this with custom sort function code?

Thanks

Re : Custom sorting arrays in PHP

There are a range of user sorting functions which you can read more about on the php.net site.

The most usual one is the usort function: you pass it the custom function that you want to apply to sort the values, and then the name of the array that you are sorting.

So the key, then, is to write the sorting algorithm: there are plenty examples of how to write custom sorting functions out there.
