I want to develop a website like file manager. Where user register and will get fix disk space lets say 20MB.
Now user can upload their pdf, doc, txt, jpeg etc files upto their disk limit.
I can develop upto this using PHP.
Now below is my issue:
1) If user's files are corrupted they can rollback their folders before 2-3 days.
Files must be secure and safe from viruses as users are uploading their important documents.
Is there any 3rd party storage server who provides such facility?
2) Also all files should be previewed from browser.
I am using Google doc viewer. Is is good and safe way to preview file in browser?
But google links are accessible from all, I need to add some restrictions as file can be viewed only by their owner.
I know it's a major task, but i just need some sort of logic. Please share your thoughts.
Thanks.
Any cloud storage service can be used for this. You'll get HDD space. There is not storage server who provides revision control system for this. You can use git, svn for this though. But as the files are binary you can not get full facility of these tools.
How file will be previewed depends on you. If you use PHP you make the site and at the backend you use the API to interact with the storage service. Google doc is not an option for this if you use PHP. Also note Google links can be made private.
I suggest you this,
Find a cloud storage service and use the storage in your server. Any will do.
Create UI using PHP and control the access using PHP too.
Manipulate files in your server directly or in 3rd party storage server via API
Use a revision control system to track the changes. And use its API in PHP end.
Some cloud storage service
Amazon S3. It also supports Versioning.
Google Cloud Storage
Microsoft Azure
Try Microsoft SkyDrive or Google Drive or Dropbox

I have project that needs to output hundreds of photos from one template file, compress them into a .zip file, and push them to the customer's browser. After that, the .zip file can be deleted.
Google App Engine (PHP) does not allow you to write files like you would in a standard web server.
How can this be accomplished with GAE flexible?
As you have already known, App Engine flexible does not allow you to write files on the system even if it runs on a VM. The reason is that it runs within more Docker containers and you will not have the guarantee that you will find the file.
An alternative for this is to change a bit your workflow and to use Cloud Storage as an intermediate. You can send the photos directly to Cloud Storage, and the users will be able to download them directly from Cloud Storage. Here you have a guide on how to achieve this from App Engine flex for PHP.
I'm trying to link php files on Google cloud storage, but getting them as plain text. I want to connect to the other file but without App Engine, all the documentation of this is written exclusively for app engine and can't even find if bucket storage has php support even tho it should. Any clue of how to link a PHP file correctly on Cloud Storage?
Google cloud storage is storage service which can store your object(files) and return when you ask for it.Files like HTML,JavaScript and CSS that render inside browser can be placed on google cloud storage to get performance in loading time.But in your php file need execution engine to run it code.Placing them on storage and accessing will get to file context.
I created a Google Cloud Platform account, deployed the LAMP server, and logged in through SFTP and uploaded my existing site.
My site is currently running on another server, so I also uploaded all my databases and everything.
On my current server with hostgator I upload files to the /home/username/public_html/uploads folder, but on google you can upload to buckets. I figured I would use their Cloud Storage instead.
I tried doing a PHP move_uploaded_file() to the bucket: gs://mybucket/uploads; however, that's not working.
What's the trick? The only documentation I can find is using the App Engine, but I'm just using the Compute Engine with LAMP installed.
Also, which would be better? Should I stick with saving the uploads to the LAMP server, or should I use buckets?
Thanks!
You could use the json api directly:
https://cloud.google.com/storage/docs/json_api/v1/how-tos/upload
There is also a PHP library for using the Google APIs in general:
https://developers.google.com/api-client-library/php/start/get_started
Then you could use that library to insert objects into your bucket with a call like this:
https://cloud.google.com/storage/docs/json_api/v1/objects/insert
If you're already running a LAMP stack, it's fine to serve files directly from the VM itself, using its local disk; you don't need to start using Google Cloud Storage for typical, simple use cases.
Google Cloud Storage, which is where the buckets terminology comes from, is useful for storing lots of files, or for serving a very large site, either for processing via Hadoop or for serving to a global audience. Because this involves more work on your part, this makes sense if your site is so popular that the cost of serving data directly from the VM is more expensive than using Google Cloud Storage.
However, Google Cloud Storage has much higher scalability than disks on a VM (though you can attach additional disks, you're limited to having up to 10TB of persistent disk per VM, and it's not an automatic process), but that depends whether your use case will need that much space.
Bottom line: if your site is working fine with the LAMP stack on your VM, it's fine to keep it. It's a good idea to keep track of your TCO so keep an eye on the cost of your compute, storage, and network traffic, and see at which point it may make sense to move some of your assets to Google Cloud Storage.
You can use Google Cloud Platform Pricing Calculator to estimate your costs, but also take a look at pricing for Google Compute Engine (which includes compute, storage, and networking) as well as Google Cloud Storage, and see how your particular use case will work out.
) i am creating a php application in google appengine. Since i will have to pay for the cloud sql, i decided to use some files instead of the sql database and read/write from it. but the problem is i am not able to create or modify the existing files using php's standard file operations like 'fopen' and 'fwrite',etc. when i run the same code in 'localhost:8080' it is working properly. but not in the uploaded version in internet. i am getting errors while creating/writing to the files. please help. thank you
You should read the appengine php runtime docs https://developers.google.com/appengine/docs/php/#PHP_The_sandbox
Specifically the section about the sandbox. The crucial statement -
An App Engine application cannot:
write to the filesystem. PHP applications can use Google Cloud Storage
for storing persistent files. Reading from the filesystem is allowed,
and all application files uploaded with the application are available.
This was a while ago, but if you still want to write to file system, you can write to the gs cloud
https://cloud.google.com/appengine/docs/php/googlestorage/#writing_files_from_your_app
you need to add the bucket to your php.ini file
google_app_engine.allow_include_gs_buckets="yourapp.appspot.com"
and make sure your Service Account Name has permissions to edit the cloud storage

If using Windows Azure and an ASP.NET web site with PHP script to upload files, can I access those files from the server or must I use the Data Storage facilities?
i.e. I'd like to reference the files directly from html\server... etc. I think I probably should be able to.
Thank you.
How are you hosting your ASP.NET website. If it's hosted in a Web Role, then you won't have access to a persistent "standard" file system for that role. (especially if you've scaled over multiple instances).
Have a look at the following tutorial on using blob storage from PHP. http://www.windowsazure.com/en-us/develop/php/how-to-guides/blob-service/
You can use the blob storage quite easily to access them with standard HTTP links from your ASP.NET site. i.e.
http://your-storage-account.blob.core.windows.net/your-container/file.txt
