Answer 1

Try this
$array = array(
'item' =>
array(
0 => 'Salt',
1 => 'Pepper'),
'quantity' =>
array(
0 => '2 spoon',
1 => '5')
);
$new_array = array();
foreach ($array['item'] as $key => $value) {
$new_array[$key]["item"] = $value;
$new_array[$key]["quantity"] = $array['quantity'][$key];
}
echo "<pre>";
var_dump($new_array);

Answer 2

Do it as below -
<?php
$arr=array(
'item' =>
array(
0 => 'Salt' ,
1 => 'Pepper'
),
'quantity' =>
array (
0 =>'spoon',
1 =>'5'
)
);
$result=array();
$com=array_combine($arr['item'],$arr['quantity']);
foreach($com as $k=>$v)
{
$result[]=array("item"=>$k,"quantity"=>$v);
}
print_r($result);
?>
OUTPUT
Array (
[0] => Array ( [item] => Salt [quantity] => spoon )
[1] => Array ( [item] => Pepper [quantity] => 5 )
)

Answer 3

try this, I think this would help you,
$a = array(
'item' =>
array(
0 => 'Salt',
1 => 'Pepper'),
'quantity' =>
array(
0 => '2 spoon',
1 => '5')
);
$i = 0;
foreach($a['item'] as $row){
$b[$i]["item"] = $row;
$b[$i]["quantity"] = $a['quantity'][$i];
$i++;
}
print_r($b);
Output from print_r() will be
Array
(
[0] => Array
(
[item] => Salt
[quantity] => 2 spoon
)
[1] => Array
(
[item] => Pepper
[quantity] => 5
)
)

Answer 4

You can simply use array_walk like as
$result = [];
array_walk($arr['item'], function($v, $k)use(&$result, $arr) {
$result[$k]['item'] = $arr['item'][$k];
$result[$k]['quantity'] = $arr['quantity'][$k];
});
print_r($result);

Answer 5

Hoping that your array is stored in the $array variable and that item is leading. Meaning that there is always an item in the array and not always a quantity
<?php
foreach($array['item'] as $key => $item) {
$newArray[$key]['item'] = $item;
if (isset($array['quantity'][$key]) {
$newArray[$key]['quantity'] = $array['quantity'][$key];
} else {
$newArray[$key]['quantity'] = 0;
}
?>
