whether each web wallet can only be used by one user
because although each wallet running on vps can have multiple address, but it is in the same wallet, so the one web wallet cannot be shared by many users, it can only be used by one user, is this correct?

You should move this to "Technical support"... it certainly doesn't belong here.

I'm not 100% sure what your saying with your post, and the whole VPS thing is confusing. From the title, web wallets can be used by more then one person. If you use blockchain.info, you can share your identifier, or export the private key and import it into another blockchain.info account. With coinbase, you could share the email and password. With HolyTransaction, you could share the username/password, and with xapo, share an account.

If the wallet running on one server, I think there is only one linux wallet running but with multiple addresses on the same wallet, each user use their own address althout share the same wallet, whether the different users will influence each other if they share the same wallet with different address? whether I must write some php code to seperate the different users?

It depends on the wallet you are running on your server. If you use something like Bitcoin Core, then your rpc commands must be able to separate the users' addresses because the wallet does not know that each address is separate. If you do not do this manually, then someone could end up spending another person's Bitcoin.

Thanks, I think blackchain.info running one wallet oneline and use something like php to separate the various users.
In this way, I can use the php-rpc call libary to call the commands such as sendtoaddress etc. to let people online to send coins. It become a web version of wallet

Don't do what you're thinking of doing!

A minor compromise of the public facing web-server would compromise your bitcoin. The first thing someone would do is check if your code/environment has RPC credentials, and clean it out.

DO NOT write a wallet if bitcoind stores the keys. You need to write this yourself, and make sure the server can never move funds without the users consent. Use bitcoind to sync and power your application, but asking users to put all their funds in one wallet is verging on reckless.
