Still problems with arrays...

[mkosmosports]

Ive got this multidimensional array:
Array
(
    [200701] => Array
        (
            [0] => France
            [1] => Serbia
        )

    [200611] => Array
        (
            [0] => Italy
            [1] => Italy
            [2] => England
            [3] => England
        )

    [200610] => Array
        (
            [0] => England
            [1] => England
        )
)

Im interested in doing three things with it:
1. Get the Max year/month value, so 200701.
2. Clean up the array to avoid duplicates in the subarray.

Any ideas?

Many thanks!

:P. Let me rephrase that question. Is there a way to use the max function on the value of the ID in a associative array where that value is a certain number?

[mkosmosports]

hmmm....I guess this is impossible....ok, Ill have to rearrange some things then...

Thanks!

[mkosmosports]

Damn, I hate being persistent and annoying but is this really impossible?? I mean, there is gotta be a way to somehow retrieve the highest value of the ID in an associative array and then being able to use it...

I promise Ill help people out when I gain enough knowledge... :P

sort(); then $array[0]
Because of the formatting of your post it's a bit confusing what you're trying to do.

[mkosmosports]

Yeah, thats the problem though, the ids of each 1st level array are not numeric, so sorting them will not make 0 the first id. They are dates, like 200701, 200611, etc.
Array
(
    [200701] => Array
        (
            [1] => France
        )
    [200611] => Array
        (
            [1] => Italy
            [2] => England
        )
    [200610] => Array
        (
            [1] => England
        )
)
So now what I want to do is somehow pull the 200701 out of this md array, and use it in a variable later on.

Those are still numbers. use ksort(), then foreach to go through and get the last one.
ksort($arr);
foreach($arr AS $k=>$v){
$key = $k;
}
print $k.

Thanks Jesirose! That loop does it. The query I had was ordered already so I didnt need to make use of ksort. Another array question for y'all. Can I merge/combine two arrays together (ok, I know I can use array_merge, but....), WHILE throwing out any duplicates so I come out with an array only containing all unique values in the other two arrays combined...

Thanks...

[Jessica]

look through the array functions.
Perhaps array_merge then array_unique?

[mkosmosports]

Damnit, I still cant get a certain syntax right. The following md array:
Array
(
    [Griffin] => Array
        (
            [0] => Peter
            [1] => Lois
            [2] => Megan
            [3] => Glenn
        )

    [Quagmire] => Array
        (
            [0] => Glenn
        )

    [Brown] => Array
        (
            [0] => Cleveland
            [1] => Loretta
            [2] => Junior
        )

)
How can I get all the last names(1st level array id's) when the first name (2nd level array) is Glenn?

Thanks!

[mkosmosports]

Ahhh..I got it folks, nevermind my last post. The solution is:

foreach ($arr as $value => $k)
{
foreach ($k as $key)
{
if ($key == "Glenn")
{
echo "$value;<br />\n";
}
}
}

This has given me all the last names when first name is Glenn..
