PHP cannot write to folder wither permission 777

I've just installed php on my Fedora 25 while I find I can't do file upload with it.

My php code is like this

<?php
$upload_root = "/var/www/html/upload/";
// echo isset($_FILES["file"]);
// echo $_FILES["file"]["tmp_name"];
$upload_path = $upload_root . basename($_FILES["file"]["name"]);
$done_upload = 1;
$file_ext = pathinfo($upload_path,PATHINFO_EXTENSION);

echo $upload_path;
echo "<br/>";

if (file_exists($_FILES["file"]["tmp_name"])) {
    echo "Upload success<br/>";
    echo filesize($_FILES["file"]["tmp_name"]);
    echo "<br/>";
} else {
    echo "No such uploaded file";
}

if (file_exists($upload_path)) {
    echo "File exists<br/>";
    $done_upload = 0;
} else {
    copy($_FILES["file"]["tmp_name"], $upload_path);
    if (!move_uploaded_file($_FILES["file"]["tmp_name"], $upload_path)) {
        echo "Fail to move.<br/>";
    } else {
        echo "Successful uploaded.<br/>";
    }
}
echo var_dump($_FILES['file']);
?>

I find I cannot actually upload the file because of permission denied and I already changed the folder's permission to 777 and owner to apache

[root@wifi-roaming-128-4-63-102 html]# ll

[root@wifi-roaming-128-4-63-102 html]# pwd
/var/www/html
[root@wifi-roaming-128-4-63-102 html]# 

The output from my browser looks like this

/var/www/html/upload/test
Upload success
21
Fail to move.
array(5) { ["name"]=> string(4) "test" ["type"]=> string(24) "application/octet-stream" ["tmp_name"]=> string(14) "/tmp/phpmGWuay" ["error"]=> int(0) ["size"]=> int(21) } 

The error log
