Array Manipulation Help

[lincolnway]

Here is what I am trying to do. I would like to single out a specific element or elements in an array. For example...

$a = Array("1", "2", "3");
$b = Array("1", "4", "5");

In this example I would like to pull the missing values from $a when compared to $b and place them into an array. So the results for the above two arrays would come out like this...

$c = Array("2", "3");

Basically whatever is missing in $a when compared to $b. Any ideas on how I can accomplish something like this. Any help or direction is appreciated.

Thanks

Sounds like you want to use [man]array_diff/man.

Thanks for the reply. When I use the array_diff() function I get odd results. I am not sure if it has anything to do with the fact that I am using a single dimension array.

Let me know if there is a better way to do this. Thanks again for your help.

Can you post some sample code (along with the sample data you used that produced "odd results")?
