Renaming array keys?

duckduckgoose

I have a form that allows the user to reorder a list. So, the order of the array winds up out of sequence. I want to leave the values in the order that they are sent, but I want to rename the keys so that they are in sequential order.

So, my array looks like this:

Array ( [name] => Moi [username] => Someone [plot_2] => 1430 [plot_10] => 1375 [plot_4] => 1453 [plot_1] => 1455 [plot_5] => 1427 [plot_8] => 1434 [plot_9] => 1435 [plot_6] => 1433 [plot] => Submit )

But, I want it to look like this:

Array ( [name] => Moi [username] => [plot_1] => 1430 [plot_2] => 1375 [plot_3] => 1453 [plot_4] => 1455 [plot_5] => 1427 [plot_6] => 1434 [plot_7 => 1435 [plot_8] => 1433 [plot] => Submit )

Unless, there's an easier way to get the values from the plot_x keys in the order that the appear?

You could use [man]ksort/man, or just do something like:

for($i = 1; isset($array["plot_$i"]); $i++)
    echo "Plot #$i: " . $array["plot_$i"] . "<br>\n";

Yes, but I don't want the values of the keys to change. I just want the keys to be named sequentially.

Like in example arrays, the values don't change and the order of the values don't change. But the keys are "renamed".

Right... that's why I suggested a function that maintains key/value pairings...

At any rate, I didn't think about the difference in sorting algorithms and that [man]ksort/man probably won't quite sort it as you wanted it. Looks like the easiest way to do this would be to use a for() loop as I mentioned above.
