Sorting multidimensiona l arrays on a named dimension??

I usually store info in arrays using field names

$array[1]["country"]='Germany',
$array[1]["code"]="GE";

$array[2]["country"]='United Sates"
$array[2]["code"]="US";

$array[3]["country"]='France"
$array[3]["code"]='FR"

I want to get:
$array[1]["country"]='France"
$array[1]["code"]='FR"

$array[2]["country"]='Germany'
$array[2]["code"]="GE";

$array[3]["country"]='US"
$array[3]["code"]="US";

Is there a function to sort on a field (country in this case)

thanks

Read the PHP.net page on the sort() function. There are several
multidimensiona l sort functions in the user-submitted comments at the
bottom:

Yes (as in you can use user-defined function for sorting):

A colleague has just showed me the syntax that introduces multidimensional arrays (as opposed to jagged arrays, which are similar to C++ arrays). So we defined such an array: int a= new {{1,2},{3,4},{5,6}} wonderful syntax, especially since "new" is used only once. Anyhow, we were a little surprised to see that a.Length

I will change this 8 character string with the one(8 character string) already in the file and so on. But I...

It seems so easy to conceive of the code to delete...
