PHP De-dupe Multidimensional Array

lghaman123 asked
Last Modified: 2013-12-13
I am attempting to find a method/function equivalent to array_unique() only using 3D arrays.  I can supply the key of the field that would contain the duplicate values.  The only example I've been able to find online has used the create_function() which my server doesn't seem to like.  Is there an easy way to do this?  If you can point me in the direction of a different solution that works better I'd realy appreciate it.  Thanks!
