[RESOLVED] A pain in the array

[jnorton]

Hello,

I have a multi dimensional array of numbers:
Array
(
[1] => Array
(
[0] => 13
[1] => 11
[2] => 2
[3] => 3
[4] => 10
)
[16] => Array
(
[0] => 29
[1] => 21
[2] => 27
[3] => 28
[4] => 22
)
... etc

How do I extract the first items into a new array? I.e. I would like to return an array of numbers such as 13,29 and then 11,21 and so on.

Any help would be greatly appreciated.

Cheers,

J.

You could try something along these lines:

$result = array();
foreach ($outer_array as $inner_array) {
    foreach ($inner_array as $key => $value) {
        $result[$key][] = $value;
    }
}

Laserlight, that is brilliant.

Thanks a lot for your help it has saved me another couple of hours of brain trying to figure out how to iterate over the array.

Cheers,

J.
