How to create sub.domain for user opon sign up - php

I am using php/mysql on linux servers. I want to create a user sub domain for each user upon sign up. For instance, john doe --> johndoe.example.com
The issue is, we are going to allow customizations such as adding custom features for clients wanting customizations. So, is it better we automate the process or manually create sub domains for clients requiring customizations and let other users just use basic login?
And how can i automate the process if need be?

Instead of creating subdomains, have a wildcard subdomain which is mapped into one folder and with PHP figure out which user's data you want to show.
If you are using a cPanel hosting, creating a wildcard subdomain should be pretty easy and wont require any manual adjustment to the httpd.conf file. Otherwise whenever you will add individual subdomains Apache will be restarted in the background, which is not at all good.
I rephrased my answer for clearer understanding.

Create a sub domain with only PHP (cross-host)

I have seen a lot of solutions that involve using .htaccess. I would like to know a way to create sub domains using only PHP. For my purposes, this also needs to work using non-host-specific mechanics so it would work on most hosts.
All I know is that I would need a wildcard CNAME record that says all sub domains point to x.x.x.x, but I don’t know what to do from here. What I think you need to do is create a folder that contains the code for the sub domains, and I have done this, but I cannot find a cross-host way to link the sub domain with the folder. There has to be a way to do this as I have seen it done, but I can not find a way that meets my needs.
The problem here is that PHP doesn't handle the request coming in, a web server (e.g. Apache or Nginx) does and it's the config for that software that determines where a request goes. Now the good news is that you can have wildcards in your config (at least for Apache and Nginx, YMMV if you're not using one of those), as long as you can access the config file (you'll need root access on the server). There is plenty of information available out there depending on what web server you are using so you can google that part.
Now, assuming you've done that part, in PHP you just need to check what the root domain for the request is. That information is stored in $_SERVER['HTTP_HOST'], so you can use a simple script to figure out which subdomain has been requested and then launch the appropriate script for that subdomain. Something like this should do the trick:
// Assuming request comes from https://subdomain.mydomain.com
$subdomain = str_replace('.mydomain.com', '', $_SERVER['HTTP_HOST']);
echo $subdomain // Outputs "subdomain"
This will capture multiple levels of subdomains as well, so if your request comes from https://sub1.sub2.subdomain.mydomain.com then $subdomain would contain sub1.sub2.subdomain.
Edit after comment
You can't do this with shared hosting. Basically the config panel you get with the host, when you set up a domain or subdomain it's modifying the config file on the server for you. There's no way a host would let anyone access the config through anything other than their control panel for security. It's possible that hosts will have a similar setup to your test server, where subdomains just work as they use wildcards by default, but I don't know that and there's no guarantee of that.
WordPress itself is just blogging software. It doesn't let you set up lots of separate websites with their own installations. What WordPress Multisite (I assume that's what you mean when you mention WordPress) is use a single installation to host multiple "sites", but it's still one installation, one single database. All of the posts, all the pages, they're all stored in a single database and if you got into that database you could easily include a page from one site on another just by editing some fields in the database. It's not designed for reselling or for multiple, completely separate entities. There are a whole host of security risks in doing that sort of thing. It's designed for single entities that want to split their sites up into multiple sites, but where it's all one company, or related companies. Universities with different departments is one example I read about before, each department has their own "site" and the main IT office has a super user that can access all of them as it's on one single installation.
I could do with a little more information on what you're trying to do, but it sounds like you're trying to do something like WPEngine, where they sell hosting space and install WordPress for you. But they have dedicated servers that run scripts that create the config files and install WordPress on your own individual hosting space using their servers. That's known as SaaS (Software as a Service) and from the little you have said seems what you are trying to do. People subscribe to your site and get their own instance of the software you're selling that they access through an admin portal. That's not something they can install on their own hosting, they have to use yours. That's how most companies do this sort of thing.

Allowing user specific subdomains with PHP application

I want to allow the users of my PHP application to create their own subdomains on my server.
For example, I currently operate example.com and for my premium users I manually create a subdomain like bob.example.com or jack.example.com, I point the user subdomains to the same server that runs my application which has a wildcard SSL cert.
What I want to do is have a system that will automatically create subdomains of my domain for my users when they register on my application but I'm not sure where to start on this. I'm assuming that this can't be done purely in PHP but I'm hoping someone can point me in the right direction for what I want to do here.
Thank you N.B - Wildcard domain seems to be exactly what I'm looking for.

Hosting WP app on server which already has Symfony2 app

I wrote an app for my customer in Symfony2 and we went public with that. However, I am learning right now that he had a separate Wordpress app within previous server to manage some separate product.
Now, he asks that we transfer that WP app on a new server. Being all security in mind, I cannot feel but nervous about potential impact here. I am to have the following URL setup:
www.myclientapp.com
www.myclientapp.com/some-wp
What are my options here? I can think of some, but any suggestion would be helpful.
Buy separate shared hosting and put WP there. Then do redirection from our website.
My VPS server runs with nginx and php-fpm. Can I utilize separate pools which would run under different user. I would need to review access privileges to Symfony's files.
In any case I would allocate separate mysql user and database. Those wold be enforced by strict privileges which prohibit access to my primary database.
Can you guys think of anything else?
My primary goal is: If WP is vulnerable, let it be. Under no circumstances I would allow it to compromise my Symfony2 app. I am primarily concerned about configuration files (app/config/*.yml) which contain sensitive data.
I will recommend that you use something like a sub-domain eg wp.symfony.com.
They may still be hosted on the same server, but using different virtual host directories.
With that, the apps will never see each other.
A way is running symfony under a different php-fpm user than the WP website and make sure the file/directory rights are set correctly. Then a WP exploit cannot write/read to the symfony files depending on the directory/file rights.
A better way is to use the php config open_basedir and isolate the two sites into their own "jails" this way PHP prevents including/reading files from other websites. See http://php.net/manual/en/ini.core.php#ini.open-basedir for more information.
For this to work the code should be separated into different directories, you can use nginx aliases or virtualhosts to point the domainname to the correct directory.

Building a SaaS application on Zend Framework

I am on the way of building a SaaS application using Zend Framework on PHP. Here is the basic information of the project. Its Project Management System on SaaS model. When the user registered on the site, they will get a domain name like the format:
user_name.pms.com
user_name - The chosen User Name when the user registered on the Project Management System (pms)
pms.com - is the main SaaS Server.
Currently we provide the Sub Domain on our Server. And for big firms, it won't look good and they may prefer to get their own domain instead of this default one. So there may be:
user_name.pms.com [Always Present]
user1.com [ The custom or independent domain of the User ] This custom domain needs to link into the default user url.
The full website is planning to develop using Zend Framework.
On Zend Framework, we are having following HTAccess on the root folder for its working and is below:
SetEnv APPLICATION_ENV development
RewriteEngine On
RewriteRule .* index.php
Here are my questions:
Do I really need to create Sub Domain like profile url for all users once they registered on the site ?
If it need to create Sub Domains, can PHP check whether the chosen sub domains exists or not and can create Sub Domains from the Script itself ?
If there is no need to Sub Domain, can we achieve the same goal using HTAccess in Zend Installation ?
Can you provide the HT Access code which does the following:
"user_name1.pms.com" need to redirect to "pms.com"
"user_name1.pms.com/contact" need to redirect to "pms.com/contact"
ie any request on the Sub Domain like URL must redirect to main website with the format: pms.com followed by Query String.
Very Important:
Important 1:
When I said the redirect to main website, I need to keep the sub domain like URL on the address bar but the request will be served by main website.
ie "user_name1.pms/contact" is going to be served from pms.com/contact but on address bar we still see the url "user_name1.pms/contact"
Important 2:
Whenever we uses the HTAccess to redirect the request to main Zend Server, can I identify the actual url entered on the address bar ie "site1.pms or site1.com" ?
Another Question of Custom Domain Redirection:
The custom domain name like "site1.com" or "site2.com" need to redirect to either:
Option (a): "pms.com"
Option (b): "site1.pms.com
to serve the request. Here also, I need to keep the url on address bar same like the one user entered.
Which above option is better (a) or (b) ?
Which technology does this work, domain mapping or CName ? Or Any other technology for make this working.
There are several ways to get you at least near to what you want... but to get all of the way there, you're going to need to get a little more depth.
First of all, your questions:
You may need to actually set up a whole virtual host for each user, if you intend for them to be able to interact with your site through their own domain. If you just want them to have their domain redirect to yours that can be done at their registrar (and if they can successfully use masking, which I've always found problematic, it may work completely without doing this. If you ignore the custom domain requirement, then you can manage subdomains completely through mod_rewrite without having to actually set them up.
Probably the best architecture for your site is to proactively set up whatever needs to be set up the moment that the user signs up. Don't try to do it "just in time" when the user first tries to access it, and therefore it's just as simple as displaying an error when someone, say, types in usre.pms.com rather than user.pms.com.
You can use htaccess, or the config file for your site (which is better for performance, but just strictly for "getting done" purposes, htaccess will work fine).
Google
Very Important Point #1: this is how mod_rewrite works. No worries.
Very Important Point #2: yes, so long as you include that information to be passed along in your mod_rewrite rule
Your Last Question of Custom Domain Redirection:
This is where things get complicated. You can't serve site1.com from pms.com without apache being fully aware that it's looking for site1.com (unless you get forwarding with masking to work without issue at the registrar). Generally speaking, if you're using forwarding of some sort, then you'll want them to forward to the subdomain, and all will be good completely through mod_rewrite. If they are directing the domain straight at your server, a CNAME record is probably the right choice, directing to the subdomain, but you'll still have to learn about virtual hosts and how to properly set it up to get everything to work.
I think you may be signing on for more than you realize by letting your clients have their own custom domain. You can learn how to do what you want with subdomains probably in an afternoon or a couple days tops. Figuring all of the ins and outs to working with custom domain names could take a lot longer.
The sub domains can be handled using some technique in CPanel. To add vurtual sub domains from CPanel, do the steps:
Select "CPanel - Sub Domains"
Enter star and choose your domain name
Choose the directory to which you need to redirect
And handle the redirection from your page.

Can I run both my wordpress website and non-wordpress website on same domain?

I build a client website and business system using html+php+mysql and both runs on same domain.
Recently, I feel like it would be better to separate the website and use wordpress so that the client can update their own contents instead of me doing this everytime they need to change something.
As, my client is in low budget, I was thinking whether it would be possible to run both the wordpress and business solution on same domain. If I run the business solution under sub-domain will it solve the issue or wordpress’s front controller will pickup any request related to that domain?
Is it possible at all? My suggestion would be appreciated.
many thanks,
Mahbub
It's absolutely possible, yes. And there are many scenarios you can use depending on what you want to do:
Subdomains — install everything in different subdomains, or install one thing at the root and the others in different subdomains. The subdomains normally just map into directories on the same account, so you use the same FTP credentials and so on to transfer files.
Directories — like http://www.example.com/blog. Very easy to deploy a blog this way, and just put your other stuff in the root.
Intermingling — you can actually put files (.php, .html, etc.) in the same directory as WordPress, just as long as there are no name conflicts. The default redirection rules in .htaccess will ensure that those files will get served as usual without interfering with WordPress.
Not knowing anything about your code, if it's simple enough another approach would be to create custom page templates in WordPress that invoke your code. The nice thing about this is that your pages will always have the same look and feel as the other pages in the blog, i.e. if you change/update the theme. This may or may not matter to you.
Its possible. We have implemented it for multiple sites in the following ways
Elgg as Master
FluxBB / PhpBB for forum
Wordpress for blogs
You can then share the sessions between these systems. Just process your login/ registration through only one system.
Sure, you can set the wordpress site in for example: http://blog.example.com and the website in http://www.example.com without any problem. Just need to setup that in the web server.
I did it by putting the wordpress blog in a separate directory inside the large domain. wordpress do not interfere with other php sites on the same domain.
Yes, it's possible.
We'd used Drupal for main website, ELGG for social networking, PHPBB3 for forums and Wordpress for blogging on the same domain name. We did it by using different subdomains for each site.
