Array_diff problems

Hello all. I have two arrays and when compared against each other via array_diff, I do not get any output: $myarray1 = Array ( [0] => Array ( [id] => 1 [Funding_Type] => Federal [Amount] => 10 [Frequency_Description] => Total [Other_Funding] => ) [1] => Array ( [id] => 2 [Funding_Type] => Trust [Amount] => 20 [Frequency_Description] => Per Year [Other_Funding] => ) [2] => Array ( [id] => 3 [Funding_Type] => Other Funding [Amount] => 30 [Frequency_Description] => Other [Other_Funding] => some )) $myarray2 = Array ( [0] => Array ( [id] => 1 [Funding_Type] => Federal [Amount] => 10 [Frequency_Description] => Total [Other_Funding] => ) [1] => Array ( [id] => 2 [Funding_Type] => Trust [Amount] => 20 [Frequency_Description] => Per Year [Other_Funding] => ) [2] => Array ( [id] => 3 [Funding_Type] => Other Funding [Amount] => 50 [Frequency_Description] => Other [Other_Funding] => none )) $arraydifferences = (array_diff($myarray1,$myarray2)); I need $arraydifferences to record the differences between the two. Any help is appreciated. Thanks, --Rick
