using array_search() to find values in php

Question

Im trying to search a array and navigate to the next and previous values

$ids=$res->result_array();

returns

array(3) {
  [0]=>
  array(1) {
    ["qid"]=>
    string(5) "63697"
  }
  [1]=>
  array(1) {
    ["qid"]=>
    string(5) "63706"
  }
  [2]=>
  array(1) {
    ["qid"]=>
    string(5) "63709"
  }
}

but when i try to search for the index it returns false

$curr_index = array_search($this->uri->segment(4), $q);

returns

bool(false)

$this->uri->segment(4) is the qid.

i want to navigate with the array by increasing and decreasing by one so i can get the next and previous values.

can someone please tell what am i doing wrong here?

your array is multidimensional. array_search will search the first level only and that consists of array, array, array. Also, please point out why none of http://stackoverflow.com/search?q=search+multidimensional+array+php answered your question. — Gordon, Dec 05 '11 at 07:53

You have an array of arrays, you could search it like this:

$curr_index = array_search(array('qid' => $this->uri->segment(4)), $q);

Where you are actually searching for an array instead of a string.
