[PHP-WIN] Best way to sort a multidimentional array....

[Roland Tarver]

Hello,

I need to manipulate, the following data in a number of diffierent ways (specifics follow).
Telephone extension number - 4 digits in the range 2000-2119
Total time on phone - seconds integer values
Total No. of calls - integer value
Name - A persons name

I'm purposely NOT using a database table for this data.

I'm storing the data in a multidemensional array, the stucture of which is below, and I need to sort it by "Total Time On Phone" in decending order, which is the first element of the 'embedded' array. I have got an idea of how to write a function to do this, I'm sure I can get it too work. But I figured someone must have had to do something like this b4 and so was after any advice/code and/or a more elegant way of achieving what I what?

Any ideas/comments would be well recieved.

Thanks A lot
Best Wishes
