share a folder in 2 domains using .htaccess - php

I got 2 sub-domains
c:\wamp\www\websiteA\ - http://websiteA/
c:\wamp\www\websiteB\ - http://websiteB/
inside websiteA got a folder for storing picture
c:\wamp\www\websiteA\photos\
in order websiteB want to access websiteA photo in websiteB's html I have to do link like
url: http://websiteB/1.html
<img src="http://websiteA/photos/1.jpg" />
the problem is I don't want to expose websiteA domain in websiteB, since two domain is inside one machine. Is it possible to achieve something like virtual host?
I also don't want to expose the physical path for websiteA, and don't want to duplicate the data.
I am thinking do something in websiteB .htaccess?
My goal is in websiteB html able to display photo with it own domain,
<img src="http://websiteB/photos/1.jpg" />
Edit: I think the question ask it this
way is better in order user request
http://websiteB/photo/1.jpg, the
backend actually request the file from
http://websiteA/photo/1.jpg, any idea do from .htaccess?
I am new in htaccess, I tried in .htaccess, but not success
RewriteEngine On
RewriteRule http://websiteA/photos/1.jpg http://websiteB/photos/1.jpg[NC,L]
Many Thanks!!!
PS: Solution need to work either windows / linux environment.

On Windows it depends on what filesystem you're using.
NTFS: http://en.wikipedia.org/wiki/NTFS_symbolic_link
FAT32 doesn't support symlinks.

Sound doggy? Can you supply reason?
What you are probably looking for is a proxy. Check it out on google

I think I got my solution, not sure is perfect or not
inside .htaccess for websiteB
RewriteEngine On
RewriteBase /websiteB/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^photos/(.*)$ http://websiteA/$1 [L]
the thing I found it not so perfect is when I enter
http://websiteB/photos/1.jpg, it will redirect to http://websiteA/photos/1.jpg
but inside the HTML, I type
<img src="http://websiteB/photos/1.jpg" />
It able to load http://websiteA/photos/1.jpg without change the URL. That's look OK for me.

Moving a HTML site to PHP

I currently run a site with 750 pages of .html webpages (yeah I know it was a stupid idea, but I'm a novice). I'm looking to move these to php. I don't really want to set up 750 individual 301 redirects and rewrite each page to .php
I've heard that I can use htaccess to this. Anyone know how?
A few additional questions -
Can I permanently redirect these links from html to php without losing my search engine rankings and
if I want to add php to each of the files (i.e. a php file menu (using the include command) to make the links quicker to update will this work? Because won't they still be html files?
Sorry for the stupid questions, but I'm still learning.
Congratulations on a 750 page site - you must have put some work into that.
To collect your current list of pages use a tool called xenu to create an export into excel. You can then easily change the name the files to PHP in column b and create a .htaccees file.
However why would you want 750 php files? If you have lots of data pages, make it one page and suck in the HTML main content and reference one page. If you have a page called warehouse-depot-22-row-44.html then change that to show-warehouse-row.php?depot=22&row=44 and return that content only. This will significantly reduce your number of pages and to start using databases to render the content.
For redirecting you could use the Apache Module mod_rewrite: https://httpd.apache.org/docs/current/mod/mod_rewrite.html
You can use url rewriting to match a specific file name request with a regular expression and then decide where to redirect if matched
RewriteRule ^myname/?$ myname.php [NC,L]
http://www.addedbytes.com/articles/for-beginners/url-rewriting-for-beginners/
Depends on the structure you have.
You want the user to access them in their natural location?
/public_html/folder1/file.php
user would access like
mydomain.com/folder1/file
or you want to map them differently?
Personally I think I would use a rewrite rule to map all requests to my /public_html/index.php and would map the requests from there using php (using include for instance). This gives great flexibility, plus you have a single point of entry for your application which is very beneficial since you can easily maintain control of the application flow.
The .htaccess would look like this
#
# Redirect all to index.php
#
RewriteEngine On
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# RewriteCond %{REQUEST_URI} !^/index\.php
# RewriteCond %{REQUEST_URI} (/[^.]*|\.(php|html?))$ [NC]
RewriteCond %{REQUEST_URI} (/[^.]*|\.)$ [NC]
RewriteRule .* index.php [L]
of course I place all my not directly accessible files (everything except index and css, js, images, etc) to a folder outside the public_html to ensure no user can ever access them directly ;)
I've had a similar (yet much much smaller) site that went through the same thing.
I have this in my .htaccess:
RewriteEngine On
RewriteRule ^(.*)\.html$ $1.php [L]
This will help redirect any visitors to your .html addresses to your .php addresses.
You hopefully have an IDE (I recommend Aptana), and you can use some of the find/change functions project-wide, and hopefully with some time and patience get your internal links from .html to .php.
But, I caution you a little bit - Perhaps it is time to look into a database based CMS, such as Wordpress or Drupal?

How to understand PHP's URL parsing/routing?

I just inherited a website built in PHP. The main page of www.mysite.com has a href to www.mysite.com/index/35.html somewhere in the page. In the site's root directory and its children there is no document 35.html.
The number 35 is actually an id found in a DB which also holds the html contents of the page.
If I load URL: www.mysite.com/index.php?id=35 the same page loads.
How does PHP know how to automatically convert
/index/35.html
to
/index.php?id=35
EDIT
Based on the answers, I have found a .htaccess file containing rewrite instructions that would explain the functionality.
However, IIS doesn't seem to (or is not configured) know how to use this. (probably because this is an Apache feature?)
So this begs the following question: Is there a way to configure IIS to work with this?
it will be done usign URL Rewriting using .htaccess - should be in the webroot.
It may look something like:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php [QSA,L]
May have other bits, but what this basically tells apache is to send anything that DOES NOT physically exist to index.php
It doesn't. There is a mod_rewrite rule that rewrites from /index/foo to /index.php?id=foo, either in a .htaccess file somewhere or in the httpd configuration itself.
RewriteEngine On
RewriteRule ^index/([\d]+)\.html /index.php?id=$1 [NC,L]
This is off the top of my head. Any browsers trying to load an address starting with index/ has any number ending in .html will be internally redirected to index.php?id= whatever the number is.
Edit: Just saw that your working on IIS. This probably won't work for you. Sorry.
I think you will be using .htaccess to redirect all requests to index.php. From there You can pass the query string a routing class, which will parse the url and identify the unique ids.
In this case we can say like, your routing class will parse the request /index/35.html to indexController, indexAction, id=35. now you can pass this id to the model to get corresponding page contents
NB : Here I a am assuming you are using mvc pattern. Anyway it can be treated in your own way, with the concept remaining the same. Hope this make sence.

Block certain site from accessing a certain file

I have player.php file which calls the video player to play a certain video. How can i block certain sites from accessing this file and using it to embed videos on there site. In other words What code can i use inside player.php to block certain sites from accessing this file only.
You can do this on three levels.
1) Web server
For instance, using .htaccess file if you're on an Apache server.
This could be done with a rewrite that pushes them to some dummy file or 404 or whatever you like. For example:
RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC]
RewriteRule .* - [F]
This is really the ideal way because it precludes the need to interpret PHP.
2) PHP
In your page, use the $_SERVER['HTTP_REFERER'] (which may not be set if there is no referrer) and search for the domain in question in the string.
This is second best, and may be your only option if you can't alter the Apache configuration.
3) Javascript
Doesn't really prevent access to anything, because the check happens client-side (they've downloaded player.php and the Javascript itself prior to running it). If they went directly to the video or whatever, it wouldn't stop them from getting the file. You would use the document.referrer and search for the domain as with the PHP example.
If you are using Apache and have access to your .htaccess file, I suggest you use that instead. This page is an excellent resource.
You could try something like this, assuming player.php is in your web root:
RewriteEngine On
RewriteCond %{HTTP_REFERER} ^player\.php.*
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?your-domain\.com/ [NC]
RewriteRule .* http://your-domain.com/please-dont-steal\.php[NC]
You're better off dealing with this issue server side, so PHP is a good bet. You'll need to examine the HTTP referrer header to see whether you're being hotlinked.
there are lots of tricks you can do with Apache mod-rewrite and/or .htaccess

Directly adding username to URL PHP

I would to know how one is able to append a username directly to a site url without having to put it within a query?
Eg
www.myspace.com/micheal
instead of
www.myspace.com?name=micheal
Without having to create a new folder for the user so that when the url is typed including the name, the surfer is taken directly to the user's profile.
Thanx
If you're using Apache, which, using PHP, you most likely are, look into mod_rewrite. This lets you do things like this, where www.myspace.com/micheal would be translated internally to www.myspace.com/?name=micheal before being sent to the scripts.
Take a look here http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html for the documentation on how to use it.
For the Apache web-server .htaccess file with the following code will do the thing.
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?name=$1 [QSA,L]
This is called url rewriting, and is handled by mod_rewrite on Apache servers.
A rewrite rule takes the incoming uri, parses it and rebuilds it into what the script needs to run.
A very simple example:
RewriteRule ^michael$ /?name=michael$
There's lots on Google when you know where to look. Start here:
http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html
As everyone has pointed out you want URL Rewriting.
If you are using IIS rather than Apache, there are still a couple of options.
Free Option - Ionics Isapi rewrite filter
Commercial Option - Isapi_Rewrite
I think you might be referring to "Pretty URLS" which is generally setup on a web server level using something like Apache mod_rewrite:
http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html
http://www.roscripts.com/Pretty_URLs_-_a_guide_to_URL_rewriting-168.html

Is PHP allowed to modify .htaccess file in current folder?

I have a PHP web app located on shared hosting.
My goal is to modify .htaccess file from PHP code when the PHP page is running.
I need that .htaccess to insert a couple of mod_rewrite lines into it.
The problem is that on Windows+Apache I can dynamically modify .htaccess file
but the same code on Linux reports a problem when I try to access this file in any
way (copy or fopen):
"failed to open stream: Permission denied"
I have given .htaccess file 777 permissions - still no result.
WHat prevents me from doing this? How can I develop a workaround?
P.S.
My initial goal was to be able to add a new RewriteRule into .htaccess that maps a
newly added category_id with new category_name.
If it wasn't shared hosting, I would use something like RewriteMap (in main Apache config) and would be able to access the map file.
This is the first real limitation I've been unable to tackle with PHP+Apache, but I hope it's circuventable too.
This seems like an overly-complex solution to just having a general "load category" page that takes the category name from the URL and loads the corresponding ID.
For example, if the URL is:
http://yoursite.com/category/programming
I would remap that to something like:
http://yoursite.com/category.php?name=programming
I want to suggest something else that also works. Instead of writing a rule for every 'special' url, why not use one for all?
I found it a whole lot easier to use what wordpress uses: every url is redirected to the index.
All you have to do is, set up the index file, read in the directory that was loaded (perhaps using $_SERVER['URI_REQUEST']), and deal with it.
add to .htaccess this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Thanks to that chunck you have a system somewhat unlimited at your disposal. If you ever feel like renaming you categrory url, or add another special case, it's already ready!
You only need a small set of rewrite rules. To do what Chad suggests:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/category/.*$ category.php [QSA]
Thus, anytime someone navigates to /category/category_id, the request will be directed to category.php, which will be handed the /category/ URI in $_SERVER['REQUEST_URI'], from which you can easily get the category ID, and you don't need to bother with editing the .htaccess file every time you add a category.
While I agree with the above comments, it can definitely be done. PHP apps like WordPress do exactly this based on changes made on the settings page. It should be as simple as writing the file out however the parent directory NEEDS to have permission for the web server user to write to it.
If it isn't working for you the trick will be making the parent directory either 777 or 775 and having the group set to whatever group Apache runs under (usually "apache" or "www" or something similar)
Adam (commented on your question) is quite correct though, some other security layer on your server might be preventing you from doing this, and this is probably a good indication that you might be approaching the problem the wrong way.
I agree with Chad Birch. In case you can't be dissuaded, though, in your situation I would first be looking for parent directories with locked-down permissions.
FYI, one of the reasons that rewriting the .htaccess is a bad idea is that any requests that come in while the .htaccess is being rewritten will not have any of your redirects applied.
