I have an array with several entries.

A common key inside is "date_timestamp"

Lets pretend this array is called $items

How do i organise the elements inside $items by the common key "date_timestamp" which is a unix time stamp?

If you are reading the array of entries from a database, you can use "ORDER BY" (MySQL command) to sort entries based on date. Other than that, you can give ksort() function a try. Can't give specific answer without seeing your code.

^ The best idea :)

If you are stuck with the array as it is though you could try a usort() but it really depends on the format of it.
