Bug #12789 Updated: array_unique() always returns only 1 result for multi-dimentional arrays

ID: 12789 Comment by: james@ractive.ch Old Reported By: bystruev@yahoo.com Reported By: james@ractive.ch Status: Bogus Bug Type: Arrays related Operating System: Cobalt Linux PHP Version: 4.0.6 New Comment: I think you should mention that in the manual, esp. because array_unique worked with multi-dimensional arrays for versions < 4.0.6 I was wondering today why my search script did now work anymore until i saw that my host updated to 4.1.1...
