How to replace/assign json values in laravel using foreach?

Question

I have a JSON which I used to create html form, now I want to submit values and replace json values responding to their category and save them elsewhere.

Here is the JSON:

    "subject":"Birth place verification",
    "preface" : "To Whom it may concern । ",
    "content" :[
        {
            "type":"label",
            "value":"previous VDC"
        },
        {
            "type":"text",
            "value_category":"vdc_municipality_name",
            "value":"",
            "width":"300px",
            "input_type":"text"
        },
        {
            "type":"label",
            "value":"ward number"
        },
        {
            "type":"text",
            "value_category":"ward_number",
            "value":"",
            "width":"80px",
            "input_type":"number"
        }]
}

Now here is what is tried:

 $formData = json_decode(File::get(public_path('english-form.json')), true);
    $form_content = $formData['content'];
    foreach($form_content as $key => $field ){
        
        if ($field['type'] == 'text'){
          $value_category = $field['value_category'];
          $field['value'] = $request->$value_category;
        //   return $field;
        }
       
    }
    $updatedJsonData = json_encode($formData, JSON_PRETTY_PRINT);
    return $updatedJsonData;

I tried to get request name, from json then assign value to respective field. while returning field, the value is changed, but outside for each updatedJsonData has no change.

This is because the foreach uses call by value. Either replace `$key => $field` with `$key => &$field` or use `$form_content[$key]['value']` — Sachin Bahukhandi, Jun 05 '23 at 07:13
