Multi-dimentiional Array searching issue

[redwax]

I am having a few issues searching a multi-dimensional array which has been created an xml file. The xml files may vary and I want to be able to search for a a key and output some values but am stuck! :queasy:

The array looks something like this:

Array ( 
	[gallery] => Array ( 
			[_c] => Array (
				[title] => Array (
					[_v] => Architecture 
					) 
			[paypal] => Array (
				[_a] => Array (
					[custom] => true 
					[default] => true 
				)
				[_c] => Array ( 
					[option] => Array (
						[0] => Array ( 
							[_c] => Array ( 
								[size] => Array ( 
									[_v] => 6x9 
								) 
								[price] => Array ( 
									[_v] => 7 
								) 
								[finish] => Array ( 
									[0] => Array ( 
										[_v] => Gloss 
									) 
									[1] => Array ( 
										[_v] => Matte 
									) 
								) 
							) 
						)  

					) 
					[disclaimer] => Array ( 
						[_v] => alsorts of stuff 
					) 
				) 
			) 
			[exif] => Array ( 
				[_a] => Array ( 
					[enable] => false 
				) 
				[_c] => Array ( 
					[detail] => Array ( 
						[0] => Array ( 
							[_v] => comment 
						) 
						[1] => Array ( 
							[_v] => iso 
						) 
						[2] => Array ( 
							[_v] => aperture 
						) 
						[3] => Array ( 
							[_v] => shutter speed 
						) 
						[4] => Array ( 
							[_v] => focal length 
						) 
					) 
				) 
			) 
		) 
	) 
)

In this instance, I am trying to search for the presence '[disclaimer]' and if it is there, output its contents, in this instance the value of [_v] ('alsorts of stuff '). I have looked on the manual pages and found various multi-dimensional array recursive search functions but haven't managed to get anything working.

I appreciate this array is complicated.

Any help would be very gratefully accepted as I am stumped!

Thank you

Untested:

function mySearch($array, $key)
{
   $result = null;
   foreach($array as $ix => $value)
   {
      if($ix == $key)
      {
         $result = $value;
         break;
      }
      elseif(is_array($value))
      {
         $result = mySearch($value, $key);
         if($result !== null)
         {
            break;
         }
      }
   }
   return $result;
}

$valueYouWant = mySearch($yourArray, 'disclaimer');

Hi NogDog

Thanks for your help on this!

This does work, except for when searching for anything that falls after the [option] entry, which forms the deepest part of the array. The result I get is this section outputted and the search term ignored.

It is as if it recurses to this depth but can't recurse back up. I may be talking rubbish with this theory of course.

Cheers
