Php rearrange array according to the key - php

Question

I tried convert the array type from $data to $data2 but didn't have success.
In the $data array all values placed according to dates.
But in the $data2 values are placed according to the title.
I wonder if it's convertable array.
$data['Group1']['Date1']['Empty'] = 5;
$data['Group1']['Date1']['Reservated'] = 1;
$data['Group1']['Date1']['WillReturn'] = 3;
$data['Group1']['Date1']['Remains'] = 1;
$data['Group1']['Date2']['Empty'] = 2;
$data['Group1']['Date2']['Reservated'] = 2;
$data['Group1']['Date2']['WillReturn'] = 3;
$data['Group1']['Date2']['Remains'] = -3;
$data['Group2']['Date1']['Empty'] = 0;
$data['Group2']['Date1']['Reservated'] = 1;
$data['Group2']['Date1']['WillReturn'] = 3;
$data['Group2']['Date1']['Remains'] = -4;
$data['Group2']['Date2']['Empty'] = 10;
$data['Group2']['Date2']['Reservated'] = 1;
$data['Group2']['Date2']['WillReturn'] = 1;
$data['Group2']['Date2']['Remains'] = 8;
$data2 = [
'Group1' => [
[ 'Title' => 'Empty',
'Date1' => 5,
'Date2' => 2,
],
[ 'Title' => 'Reservated',
'Date1' => 1,
'Date2' => 2,
],
[ 'Title' => 'WillReturn',
'Date1' => 3,
'Date2' => 3,
],
[ 'Title' => 'Remains',
'Date1' => 1,
'Date2' => -3,
],
// etc...
],
'Group2' => [
[ 'Title' => 'Empty',
'Date1' => 0,
'Date2' => 10,
],
[ 'Title' => 'Reservated',
'Date1' => 1,
'Date2' => 1,
],
[ 'Title' => 'WillReturn',
'Date1' => 3,
'Date2' => 1,
],
[ 'Title' => 'Remains',
'Date1' => -4,
'Date2' => -8,
],
// etc...
],
// etc...
];
Some try here:
$new = [];
$grp = array_keys($datax);
$i =0;
foreach($datax as $key => $val)
{
$dates = array_keys($val);
foreach($val as $k=>$v)
{
$cases = array_keys($v);
$caseAndVals[$i]=$v;
$i++;
}
}
$z =0;
$y = 0;
foreach($grp as $g)
{
foreach($cases as $c)
{
$new[$g][$z]['Title']=$c;
foreach($dates as $d)
{
$new[$g][$z][$d] = 'values which correspond to the date and title';
}
$z++;
}
}
I converted array according to group and cases but i didn't have success to place values corresponded dates...

You're very close.
To get the values which correspond to the date and title, use $data[$g][$d][$c].
And you need to reset $z to 0 each time through the $grp loop, so you get correct indexes on each group array.
$new = array();
$grp = array_keys($data);
foreach($data as $key => $val)
{
$dates = array_keys($val);
foreach($val as $k=>$v)
{
$cases = array_keys($v);
$caseAndVals[]=$v;
}
}
foreach($grp as $g)
{
$z = 0;
foreach($cases as $c)
{
$new[$g][$z]['Title']=$c;
foreach($dates as $d)
{
$new[$g][$z][$d] = $data[$g][$d][$c];
}
$z++;
}
}
