Question

If my array is formatted like this:

Array ( 
       [0] => Array ( 
                     [0] => Informatics [TitleName] => Informatics 
                     [1] => Informatics [TitleValue] => Informatics 
                     [2] => 1 [CategoryID] => 1 
                     [3] => [SecondaryCategory] => 
                     ) 
         )

How do I pull out all the values that are CategoryID == 1 ?

Ive tried several while loops but it does not seem to be working properly. Can Anyone help me out with this? Perhaps a while loop is not what I need.

Search for a value inside an array:
http://php.net/manual/fr/function.array-search.php

mixed array_search ( mixed $needle , array $haystack [, bool $strict = false ] )

Returns the key in the array ($haystack) if the value ($needle) exists.
Returns FALSE if the $needle is not found in the $haystack.
