  )
)

Array (
  [0] => price Object (
    [mailservice] => Priority Mail<sup>&reg;</sup> Medium Flat Rate Box
    [rate] => 11.35
  )
)

…yeah. I need to search through these and pull out the RATE value, which here is 11.35.

For/each loops have failed me so far, any other ideas?

Here is a function to do this for you:

findKey($myarray,$searchKey) {
    foreach($myarray as $key=>$value) {
       if($key==$searchKey) return $value;
       if(is_array($value) || is_object($value)) {
           $returned = findKey($value,$searchKey);
           if($returned) return $returned;
       }
    }
    return false;
}

// call it like this:
findKey($yourArray,"rate")
