    Can you format it, or make it somewhat readable? Commented Mar 1, 2011 at 12:24

Reset to default
1 
function get_index($array, $meta_key)
{
  for($i=0;$i<sizeof($array);$++)
  {
    if($array[$i]['meta_key'] == $meta_key) return $i;
  }
}

usage:

$array = array( ... );

$index = get_index($array, 'data2');

you can try :

foreach($key1 as array_keys($array) {
    $key2 = array_search('meta_key', $array[$key1]);
}

to retrieve the $key of 'meta_key'

This should work for you: 

$output=array();
    foreach ($arr_data as $key=>$value)
    {
       if($value['meta_key'] == 'data2')
       {
         $output[$key] = $value;
       }
    }

    echo "<pre>";
    print_r($output);
