PHP: Get n-th item of an associative array

Question

If you have an associative array:

Array (     [uid] => Marvelous     [status] => 1     [set_later] => Array         (             [0] => 1             [1] => 0         )      [op] => Submit     [submit] => Submit ) 

And you want to access the 2nd item, how would you do it? $arr[1] doesn't seem to be working:

foreach ($form_state['values']['set_later'] as $fieldKey => $setLater) {     if (! $setLater) {         $valueForAll = $form_state['values'][$fieldKey];         $_SESSION[SET_NOW_KEY][array_search($valueForAll, $form_state['values'])] = $valueForAll; // this isn't getting the value properly     } } 

This code is supposed to produce:

$_SESSION[SET_NOW_KEY]['status'] = 1 

But it just produces a blank entry.

Use array_slice

$second = array_slice($array, 1, 1, true);  // array("status" => 1)  // or  list($value) = array_slice($array, 1, 1); // 1  // or  $blah = array_slice($array, 1, 1); // array(0 => 1) $value = $blah[0];
