尝试使用PHP上传文件？

I'm trying make a file upload using PHP. To do it I'm using $_FILE but I can't understand why does not works. Looking for solutions I'm found some suggestion to use $_FILE, but still can't do this works. To I see if upload works I'm using Postman of Chrome. I'm using Ubuntu with LAMP.

How could I do it ?

<?php

$arquivo = isset($_FILES["file"]) ? $_FILES["file"] : FALSE;

if(!$arquivo) { 
    echo "You can not access this file directly!"; 
}else{
    $diretorio = "/home/fernando/Imagens/";

    if (move_uploaded_file($arquivo["tmp_name"], $diretorio.$arquivo["name"])) { 
            echo "File upload ok!"; 
    }else{
         echo "File not upload!"; 
    }   
}

?>

Exception

Postman

Your script doesn't have permissions to add and/or execute files in /home/fernando/Imagens/. Your will have to use chmod:

chmod -R 775 /home/fernando/Imagens
