PHP order array by date?

PHP Sort a multidimensional array by element containing date

I have some data from XML or JSON in a PHP array that looks like this:

[0]= array(2) {
    ["title"]= string(38) "Another title"
    ["date"]= string(31) "Fri, 17 Jun 2011 08:55:57 +0200"
}
[1]= array(2) {
    ["title"]= string(38) "My title"
    ["date"]= string(31) "Mon, 16 Jun 2010 06:55:57 +0200"
}

What I want to do is order the two items by date.

Is it possible to sort by date, when the sort value is inside every item?
Do I need to convert the date format to timestamp?

What I don't want to do

I could use date and set it as the ID but that don't feel right, because two items can have the same date and then it would not be unique.
