unique multidimensional array

[mazzzzz]

Ok, i'm tring to find only the unique values in my multidimensional array...
an example being

$all = array ('0' => array ('fname' => 'max', 'lname' => 'black'), '1' => array ('fname' => 'john', 'lname' => 'wolf'), '2' => array ('fname' => 'max', 'lname' => 'tent'));

(this may not actualy work, I just came up with it..)

What I want to do with this is assign $unique (another array) with the first fname value that match and not the rest... So then $unique would equal

$unique = array ('0' => array ('fname' => 'max', 'lname' => 'black'), '1' => array ('fname' => 'john', 'lname' => 'wolf'));

It would equal this because the 0 fname and the 2 fname were the same, so it deleted the newer one and kept the older one...
Help on this would be great.

I wouldthink there is a function
for finding unique values in array

of course if testing sub dimensions,
you may need to use a foreach loop to check,
using some such function inside the foreach loop

Here is a list of all php array functions, along with short description:
http://docs.php.net/array

for example:
[man]in_array[/man] is quite useful and simple to use, to check for needle in haystack
