Whats the easiest way to invert a multidimensional array. By invert I mean similar to array_flip.
e.g
[0][5][var_name] = data
[0][3][var_name2] = data2
[1][var_name3] = data3
[0][1][4][var_name4] = data4
inverted would be:
[var_name][0][5] = data
[var_name2][0][3] = data2
[var_name3][1] = data3
[var_name4][0][1][4] = data4
Any ide...

Let's say I have two arrays:
int[] array1 = new int[2000000];
int[] array2 = new int[2000000];
I stick some values into the arrays and then want to add the contents of array2 to array1 like so:
for(int i = 0; i < 2000000; ++i) array1[i] += array2[i];
Now, let's say I want to make processing faster on a multi-processor machine, so i...

Hi,
I am trying to dynamically assign a 2d array to a pointer in a constructor initialize.
FooBar::FooBar()
: _array( new int[10][10] )
{ }
int **_array;
However this does not work. I understand that multidimensional arrays are allocated a bit differently. Is anyone able to elaborate on this with an explanation?
Thanks in advan...

Hi all,
Let me illustrate this with an example.
Consider there are 10 books (there may be more, even 100+ on a single screen). A customer can order any number of books. In the fontend, each book is represented in a row and the book details are arranged column wise. Now the 10 books (along with their details) are shown in 10 rows.
BOO...

I have a menu being built via a multi-dimensional array. A current item is set by matching its url attribute with the current request. I want this value to bubble up to its parents, but I can't for the life of me get it working - I'm sure I've been close, but it's proving a bit tricky. Here's the array:
