modify json using form and PHP

Question

I'm developing a page that takes the info of a json, print a form with the json's values, the user can change it and now I'm trying to upload this data to override the original json with the new data. At this point, I have two arrays, one with the "keys" of the json, and another with the new data that must contain. I can't build the json in the correct way. The problem is to match the two propierties (key and data) to make an array for json_decode after.

I have:

$arrayClave with the keys of the json. and $guardar with the new data.

I have to build a new json with the keys plus the data, like this:

{"ID":"12450","MARCA":"Roly" .... }

I've tried to build the array like array($arrayClave[1] => $guardar[1]);

but I need to build it for every number of inputs, that change in different cases, so I need to use a loop, but it's not possible to do something like:

for($i=0; $i<99; $i++){
    $var = $arrayClave[$i] => $guardar[$i],;
}

$result = array($var);

I know this is not correct, but I don't know the way to do it. If someone can help me I'll be gratefull, I hope I've explained myself in the best way :) Thanks in advance!

where $arrayClave and $guardar should be arrays

 for($i=0; $i<99; $i++){
  $arrayClave[$i] = $guardar[$i];
  }

 print_r(json_encode($arrayClave));

try this

It returns syntax error, that's the problem I have with this solution. Thanks!

did you remember to remove the "," you have after $guardar[$i] in your original post?

You shouldn't have any arrows, use @KarthickKumarGanesh's solution, not your $var = $arrayClave[$i] => $guardar[$i],; solution

Why do you need to use the => at all?

Array 1: The Array that containd the Keys "tags" of the json, it comes from the previous page, by a form input:

$arrayClave

Array2: The Array that contains the values of the json, it gets the value of each input that the user has modified in the previous page:

foreach ($arrayClave as $value){
    $valorA = ($_GET[$value]);
    $guardar[] = $valorA;
}
