First, although this does work, I don't know if it's what you want to do.
You'll end up with a structure like this:
Array (
[0] => stdClass Object
( [countryContinent] => North America )
[1] => stdClass Object
( [countryName] => Canada ) )
Not very useful, as you've found.

I think this is along the lines of what you want to do:
$continent = 'North America';
$landmass[$continent][] = 'Canada';
$landmass[$continent][] = 'United States';
$landmass[$continent][] = 'Mexico';
$continent = 'Asia';
$landmass[$continent][] = 'Japan';
$landmass[$continent][] = 'China';
$landmass[$continent][] = 'Korea';
// sort continents then countries
ksort($landmass); // use ksort() to sort by key
foreach($landmass as $conti => $cntry) { sort($landmass[$conti]); }
print_r($landmass);
There's your array, just loop over it as you like, to do your output.
If you're reading an XML file, you might look into PEAR, which has
packages for parsing and building data structures of XML data.

I would suggest parsing the XML data such that you have an array of
continents, and each element of said array is an array with two elements
- the first being the contintent name and the second array containing
all countries within that continent.
So, after parsing the file you would have:
$contintents[0] = array('North America',array('Canada','United
States','Mexico'));
$contintents[1] = array('South
America',array('Ecuador','Chile','Peru','Columbia','Brazil'));
etc. etc.
HTH.

RE: [PHP] Tricky array question
It should be $category[0] = $glacier; ^--- ERROR in you code Niklas -Original Message- From: Andy [mailto:[EMAIL PROTECTED]] Sent: 5. helmikuuta 2002 11:59 To: [EMAIL PROTECTED] Subject: [PHP] Tricky array question Hi there, I have a tricky array question. My app is passing via post a array variable called glacier. Now I am checking for the content of this array. Because there are more of those arrays, I am getting all the names out of a db. How is it possible to get the value and keep the name of the array dynamic? e.g: Array name passed by post is: $glacier // contains e.g. $glacier[0] = testname Array with category names coming out of db is: $category // contains e.g. $category[0] = glacier echo $categories[0]; // returns glacier echo $glacier[0]; // returns testname I tryed $categories[0][0] but it returns only the first letter of glacier (g) Any ideas??

Re: [PHP] Tricky array question

$varname = $categories[0];
echo ${$varname}[0];
