PHP

In this part i dont have any response of try catch, no error o problem, but my file never is upload to my folder


    $data = json_decode(file_get_contents('php://input'), true);
    $fileName= $data["avatar"]["filename"];
    
    try {
        if(move_uploaded_file(base64_decode($data['avatar']['data']), $finalRute)){
                echo 'file update';
        }
    } catch (Exception $e) {
        echo 'Excepción capturada: ',  $e->getMessage(), "\n";
    }

First of all $data["avatar"]["data"] is no file but a string. So you have to create the file first using file_put_cotents() and then just copy it with rename(). move_uploaded_file only works for uploaded files which are present in $_FILES — Code Spirit
I think the data:application/pdf;base64, part is only for displaying in an <img src. I don't think you want that in the file. — AbraCadaver

You have the data encoded as base64 in memory. You will have to do something to write the data to disk instead of using move_uploaded_file, which is designed for moving a temp file on disk to a different location. The most straightforward would be file_put_contents.

Something like:

file_put_contents($finalRute, base64_decode(explode(',', $data['avatar']['data'])[1]));
