Merge two array and create new - php

Question

I have problem to create array. I have form.
Form's inputs are tag inputs. First input is option name. When you put any option name the new tag input added in the form.
I post data in controller and create auto variations for product. Eg. Red-S Red-M Blue-S Blue-M ... The Code which i'm using gives variation look like this:
array:4 [
0 => "Red-S"
1 => "Blue-S"
2 => "Red-M"
3 => "Blue-M"
]
And i have another array for option names
array:2 [
0 => "Color"
1 => "Size"
]
I want to create one array look like this:
array:2 [
"Color" => "Red"
"Size" => "S"
]
This is my Controller
function make_combinations($props)
{
if ( empty($props) ) return [];
$keys = array_keys($props);
$key = $keys[0];
$values = $props[$key];
unset($props[$key]);
$rest = make_combinations($props);
if ( empty($values) ) return $rest;
if ( empty($rest) ) return $values;
$combinations = [];
foreach($rest as $comb)
{
foreach($values as $value)
{
$combinations[] = $value . '-' . $comb;
}
}
return $combinations;
}
$inputs = explode(',', $request['option']);
$props = [];
foreach($inputs as $input)
{
$input_key = strtolower($input);
if ( !$request->has($input_key) ) continue;
$input_values = explode(',', $request->input($input_key));
$props[$input_key] = $input_values;
}
$combinations = make_combinations($props);
$result[] = compact('combinations', 'inputs');
return view('system.modules.variants', compact('result'));
}

Answer 1

If I gessed right what are you trying to achieve, having this input:
$inputs = ["Red-S-Cotton", "Blue-Silk-M"];
$keys = ['Color-Size-Material', 'Color-Material-Size'];
By doing a:
$output = array_map(function($key) use ($inputs, $keys) {
$expKeys = explode('-', $keys[$key]);
$expInputs = explode('-', $inputs[$key]);
return array_combine($expKeys, $expInputs);
}, array_keys($inputs));
$output will be:
[
[
"Color" => "Red",
"Size" => "S",
"Material" => "Cotton",
],
[
"Color" => "Blue",
"Material" => "Silk",
"Size" => "M",
]
]

You can skip one loop.
You can write code something like this
$arr = [
0 => "Red-S-Silk-Y",
1 => "Blue-S",
2 => "Red-M-Cotton",
3 => "Blue-M",
];
$arrFinal = [];
$dataArray = [];
foreach($arr AS $value){
$expArr = explode("-",$value);
if(isset($expArr[0])){
$dataArray['color'] = $expArr[0];
}
if(isset($expArr[1])){
$dataArray['size'] = $expArr[1];
}
if(isset($expArr[2])){
$dataArray['Material'] = $expArr[2];
}
if(isset($expArr[3])){
$dataArray['Style'] = $expArr[3];
}
$arrFinal[] = $dataArray;
Unset($dataArray);
}
echo "<pre>";
print_r($arrFinal);
Your output will be something like this.
Array
(
[0] => Array
(
[color] => Red
[size] => S
[Material] => Silk
[Style] => Y
)
[1] => Array
(
[color] => Blue
[size] => S
)
[2] => Array
(
[color] => Red
[size] => M
[Material] => Cotton
)
[3] => Array
(
[color] => Blue
[size] => M
)
)

Answer 3

$result = array_merge($array1, $array2,....);
