Answer 1

Removing first index can be achieve by using array_shift, see demo below.
<?php
//Enter your code here, enjoy!
$a = [
0 => [
0 => [
0 => [
'SKU' => 'T',
'title' => 'BT',
'min' => 'SPads',
],
1 => '',
],
[
0 => [
'SKU' => 'R',
'title' => 'RT',
'min' => 'XPads',
],
1 => '',
],
],
];
$a = array_shift($a);
print_r($a);
array_shift - Shift an element off the beginning of array
Output
Array
(
[0] => Array
(
[0] => Array
(
[SKU] => T
[title] => BT
[min] => SPads
)
[1] =>
)
[1] => Array
(
[0] => Array
(
[SKU] => R
[title] => RT
[min] => XPads
)
[1] =>
)
)

You can iterate in foreach loop and create new array in reqired formate.
$newAr =array();
foreach ($oldArr as $tempArr){
foreach($tempArr as $tempArr2){
$newAr[] = $tempArr2;
}
}
print_r($newArr);
