How to find the highest value in a 2d array?

Question

Array
(
    [0] => Array
        (
            [uid] => 43543534
        )
)

I'm trying to get output as [0] => [43543534]

I tried foreach() but I'm getting string as output

Update How do I find max value now in this?

Answer 1

Why don't you have only 1 dimensional array array('0' => 43543534), if you have only 'uid' in the second one

foreach ($yourArray as $key => $val) {
  echo '['.$key.'] => ['.$val['uid'].']<br />';
}
