can you sort a key in an array?

[Anon]

can you sort a key in an array?
let say you have

data[a][c]=1;
data[a][d]=2;
data[c][c][a]=3;
data[d][d]=4;

I want to sort by using [a] or or [c] etc...

Can this be done?

Well... use array_flip() to invert keys and values, sort it, and then use another time array_flip().

How exactly do you want it sorted? Do you want it to look like this:

data[a][c]=1;
data[a][d]=2;
data[c][c][a]=3;
data[d][d]=4;

or this:

data[a][d]=2;
data[a][c]=1;
data[c][c][a]=3;
data[d][d]=4;

or this:

data[c][c][a]=3;
data[d][d]=4;
data[a][c]=1;
data[a][d]=2;

After a small verification, don't use my method !! It only works with simple arrays :
$myarray["a"] = "value 1";
$myarray["b"] = "value 2";
...

let me rewrite it:

data[a][e]=1;
data[f][j]=2;
data[c][g][k]=3;
data[d][h][l]=4;
