Merge two arrays into one associative array
(2 answers)
Closed 7 months ago.
I want to change the following php array
"extra_charge_item" => [
0 => "Massage",
1 => "Pool table",
2 => "Laundry"
],
"extra_charge_description" => [
0 => "Paid",
1 => "Paid",
2 => "We wash everything"
],
"extra_charge_price" => [
0 => "200",
1 => "100",
2 => "1000"
],
I haven't been able to solve for a whole 2hrs
This is the expected output
"new_data" => [
0 => [
"Maasage", "Paid", "200"
],
1 => [
"Pool table", "Paid", "100"
],
2 => [
"Laundry", "we wash everything", "1000"
]
]

Answer 1

Rather than doing all the work for you, here's some pointers on one way to approach this:
If you are happy to assume that all three sub-arrays have the same number of items, you can use array_keys to get those keys from whichever you want.
Once you have those keys, you can use a foreach loop to look at each in turn.
For each key, use square bracket syntax to pluck the three items you need.
Use [$foo, $bar, $baz] or array($foo, $bar, $baz) to create a new array.
Assign that array to your final output array, using the key from your foreach loop.

Answer 2

Just use foreach with key => value
$data = [
"extra_charge_item" => [
0 => "Massage",
1 => "Pool table",
2 => "Laundry"
],
"extra_charge_description" => [
0 => "Paid",
1 => "Paid",
2 => "We wash everything"
],
"extra_charge_price" => [
0 => "200",
1 => "100",
2 => "1000"
],
];
$newData = [];
foreach ($data as $value) {
foreach ($value as $k => $v) {
$newData[$k][] = $v;
}
}
var_dump($newData);

I found an answer. Seems someone else had the same problem
Merge two arrays into one associative array
Here's the solution for my case;
//These are arrays passed from front end in the name attribute e.g extra_charge_item[] e.t.c
$extra_charge_item_array = $request->input('extra_charge_item');
$extra_charge_description_array = $request->input('extra_charge_description');
$extra_charge_price_array = $request->input('extra_charge_price');
$new_extra_charges_data = array_map(
function ($item, $description, $price) {
return [
'item' => $item,
'description' => $description,
'price'=> $price
];
}, $extra_charge_item_array, $extra_charge_description_array, $extra_charge_price_array);
//save the data
foreach ($new_extra_charges_data as $extra_charge) {
Charge::create([
'item' => $extra_charge['item'],
'description' => $extra_charge['description'],
'price' => $extra_charge['price']
]);
}
