无法通过PHP上传文件?

I am trying to upload a file through php

Html Form

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:</br>
    <input type="file" name="fileToUpload" id="fileToUpload"></br>
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html> 

PHP

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:</br>
    <input type="file" name="fileToUpload" id="fileToUpload"></br>
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html> 
rohit@joed:/var/www/html$ cat upload.php 
<?php
$target_dir = "/home/rohit/uploads";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?> 

Apache logs

move_uploaded_file failed to open stream: Permission denied in /var/www/html/upload.php 

on line 37, referer: http://localhost/filetest.htm

I have already tried everything mentioned here, but still facing the issue.

Here are the permissions for the folders

drwxr-xr-x  2 www-data rohit   4096 Feb 24 15:58 tmp_uploads
drwxr-xr-x  2 www-data rohit   4096 Feb 24 15:05 uploads

I got the owner from

<?php echo exec('whoami'); ?>

chown user destination_dir
chmod 755 destination_dir

and then changed the owner of the folder with that user.

Could somebody help me unblock please?

    This seems like it might be too simple, but if you're getting permissions denied, have you tried setting permissions to 0777 and testing. If it works, try 0775 (instead of 0755). If that works, then the group is causing you the problem. If that is the case, try switching the owner and the group.

    chown rohit:www-data tmp_uploads
    chown rohit:www-data uploads
