PHP Array rearrange numeric key as parrent key
i want to rearrange a simple multidimensional array.
Array
(
[pieces] => Array
(
[0] => 2
[1] => 9
)
[start] => Array
(
[0] => 0001
[1] => 9901
)
[end] => Array
(
[0] => 0002
[1] => 9909
)
[group] => Array
(
[0] => 0001-0100
[1] => 9901-9999
)
)
to
Array
(
[tokens] => Array
(
[0] => Array
(
[start] => 0001
[end] => 0002
[pieces] => 2
[group] => 0100
)
[1] => Array
(
[start] => 9901
[end] => 9909
[pieces] => 9
[group] => 9901-9999
)
)
)
I have tried something similar this:
$keys = array_keys($array);
foreach ($keys as $key => $val) {
foreach ($array as $k => $v){
foreach($array[$v] as $tk => $tv){
if($val == $k){
$new['tokens'][$val] = $tv;
}
}
}
}
The numeric is the set of tokens which i prosted from my form,
Please can anyone explain me what i do wrong?
I am working some hours with different codes (i know the solution is very simple) but I am a little bit confused :/
Thank you very much!

The Fourth Bird's solution is quite rigid in that it:
- Requires an explicitly-defined key in the loop condition.
- Enforces that the entire result has no more items than that one key has.
- Assumes and enforces that the input keys are sequential and zero-indexed.
The below will work no matter what:
foreach( $array as $y => $inner ) {
foreach( $inner as $x => $value ) {
$new['tokens'][$x][$y] = $value;
}
}
Demo: https://3v4l.org/Rmdtd
Edit: I think it's worth preserving The Fourth Bird's explanation of the trouble with the posted code from his now-deleted answer:
You are trying to index into
$array[$v], but$vin the case is one
of the sub arrays. According to the array
docs:
Arrays and objects can not be used as keys. Doing so will result in
a warning: Illegal offset type.
Make sure that you have error_reporting turned up to E_ALL while you're developing code so that you can see non-critical messages that indicate current and/or future problems.

thank you very much! I am so stupid! at first i had the same iteration like yours but i tought i have to do something with "if"-statements and linked the fals vars to $new and was wondering why i do not get the result. Thanks for clarification!
