Not entirely sure what you're asking here, or how you (or the
nginx folks) expect it to relate to PHP. Do you mean that you want to
use PHP to have theme2.php act as if it was called as theme.php?id=2 ?
I have me write a blog, but my blog has link like blogdetail.html?id=1 or =2
through 16 at moment. And for google and other Search Engines not good the
links, better where i can rewrite to a fix link, and when someone use the
link, php write to correct url.
Common SEO mythology is that you need pretty human-understandable
links. (In point of fact, the search engines care not in the least.)
However, human-understandable URLs are a benefit to users when they want
to understand what they're linking to or clicking on.
A human-understandable link is more like:
http://www.example.com/blog/2013-05-a-day-in-the-life-of-my-dog
not:
http://www.example.com/blog/2
as that really does not provide any more information than:
http://www.example.com/blog.php?id=2
Otherwise, Daniel's solution below should do the trick.
Sorry my english not perfect on earth.
If so, it's not redirect or rewrite, and it's extremely hacky, but
this is the only real way PHP could achieve the desired result:
?php
// dynamictheme.php
if (preg_match('/.*([0-9]+)\.php/Ui',$_SERVER['PHP_SELF'],$match)) {
$_GET['id'] = $match[1];
include dirname(__FILE__).'/theme.php';
}
?
Then just symlink dynamictheme.php to your various themes like so:
ln -s dynamictheme.php theme2.php
ln -s dynamictheme.php theme301.php
ln -s dynamictheme.php theme18447.php

I had the same problem with PHP after I've upgraded to 4.3.3 from 4.3.1. I was tearing my hair out but couldn't figure out what was wrong. I ended up editing my php.ini file and turning REGISTER GLOBALS = On. It works fine now and since this is on my development box I don't really care about security that much. Hope this helped...

As was previously suggested just do a

to see what, if anything,

Ryan,
This would have been solved a lot quicker on a list dedicated to Apache.
I tested this, and it works:
.htaccess
---
#Options +FollowSymlinks
IfModule mod_rewrite.c
RewriteEngine On
RewriteRule ^tt.php/(.*) tt.php?id=$1
RewriteRule ^tt.php/(.*).php tt.php?id=$1
/IfModule
---
With this tt.php file:
---
h1tt.php/h1
pre
?
print_r($_GET);
?
/pre
---
A few notes:
- I commented out the Options line because *my* Apache set-up doesn't
need it, but yours may (it depends on the httpd.conf file).
- I've tested the above with the following URLs:
- http://indentclients.com/tests/ryan/tt/45.php
- http://indentclients.com/tests/ryan/tt/45
- http://indentclients.com/tests/ryan/tt/45/
- http://indentclients.com/tests/ryan/tt.php/45.php
- http://indentclients.com/tests/ryan/tt.php/45
- http://indentclients.com/tests/ryan/tt.php/45/
In all cases, it output:
Array
(
[id] = 45
)
- it also works for me without the IfModule... and /IfModule lines
- if this STILL doesn't work, it's more than likely that your host does
not allow mod_rewrite, doesn't allow you total freedom in your
.htaccess file, etc etc -- find a new host.

It doesn't look like your rule would match. Try:
RewriteRule ^show/(.*)/(.*)/(.*)
Another way to achieve a similar result without using Rewrite is to parse
$_SERVER['REQUEST_URI'], and possibly $_SERVER['PATH_INFO']
Eg if your link is:
http://www.rizkhan.net/articles/show.php/Beginners%20Corner/1/1
Then $_SERVER['REQUEST_URI'] would contain
/articles/show.php/Beginners%20Corner/1/1
and $_SERVER['PATH_INFO'] would contain
/Beginners%20Corner/1/1
Ryan,
I'm doing what I believe Jason is indicating above. I'm sure in your
research you read the articles about URL rewriting on A List Apart,
specifically this one: http://www.alistapart.com/articles/succeed/. Using
a similar approach, I'm saving page content in a database with the unique
identifier set to the desired value of $REQUEST_URI. After redirecting all
requests to index.php as described in the article, I use code in index.php
similar to what's in the article, plus this for the database content:
-
// check for database content
$conn = db_connect();
if (!$conn) {
$db_error = mysql_error();
include(error_page.php);
exit();
}
// get the page details from db
$request = substr($REQUEST_URI, 1);
$results = mysql_query(SELECT DisplayStatus FROM Pages WHERE
MenuPath='$request' AND DisplayStatus='Y');
if (!$results) {
$db_error = mysql_error();
include(error_page.php);
exit();
}
if (mysql_num_rows($results) 0) {
include(page.php);
exit();
}
// if request has not been matched, include custom error page
include(notfound.php);
exit();
-
That pulls page content based on $REQUEST_URI. I build site menus from the
database, using values from the MenuPath field as URLs.

Hey,
I put this in for testing:
if(isset($_GET[id])){echo Got \$_GET[id]br;}else{echo No
\$_GET[id]br;}
if(isset($_GET[sid])){echo Got \$_GET[sid]br;}else{echo No
\$_GET[sid]br;}
and heres the output:
No $_GET[id]
No $_GET[sid]
So the variables are not being passed
Any idea why and what I can do about this?

As was previously suggested just do a
print_r($_GET)
to see what, if anything, you're getting.

\$_GET[id]br;}
if(isset($_GET[sid])){echo Got \$_GET[sid]br;}else{echo No

print_r($_GET);
print_r($_GET['id']);
print_r($_GET['sid']);
and heres the output:

No $_GET[id]
No $_GET[sid]

Re: [PHP] URL rewriting...anybody done this?
Hi again,
I did a little pokeing around and installed this on 3 differient
serversand the results were identical...
so its not the servers fault but something with the directives...
got some interesting results with my testing
am using this:
echo Ok,we are in show.phpbr;
if(isset($_GET[id])){echo Got \$_GET[id]br;}else{echo No
\$_GET[id]br;}
if(isset($_GET[sid])){echo Got \$_GET[sid]br;}else{echo No
\$_GET[sid]br;}
print_r($_GET);
This is still not working:
http://rizkhan.net/articles/show/2/1
(output is: )
Ok,we are in show.php
No $_GET[id]
No $_GET[sid]
Array ( )
This gives the exact expected results (working)
http://rizkhan.net/articles/show/?sid=1id=2 (note I dont have to write
show.php)
This gives me screwy results:
http://rizkhan.net/articles/show/?1/2
(output is: )
Ok,we are in show.php
No $_GET[id]
No $_GET[sid]
Array ( [1/2] = )
in case you guys forgot, this is what i entered into my httpd.conf:
Directory /path/to/directory #of course i entered the correct path#
Options ExecCGI FollowSymLinks Includes MultiViews
AllowOverride all
/Directory
This is my htaccess file:
RewriteEngine On
RewriteRule ^show/(.*)/(.*) /show.php?sid=$1id=$2
incase i forgot to mention it...this #¤#¤# thing is not working.
ANY ideas?
Thanks,
-Ryan

Re: [PHP] url rewriting within sessions - confused newbie needs help - [FIXED]

Jason, Thanks for your help. It is a little clearer to me now. However, I have visited php sites that *claim* to be using session management but where the links do not have the session id appended, and there are no variables being passed in the url for links. The url is always in the form www.somesite.com/index.php or just www.somesite.com. In these cases, how is the url rewriting being suppressed for the links on the page? I simply want to understand the technique.

I simply want to understand the technique. If url rewriting (session.use_trans_sid) is enabled, and your browser is accepting cookies, then the sequence of events goes like this: 1. First request to your site -- browser has no cookie set, so cannot send it. 2. PHP responds with a page, including a header to set the PHPSESSID cookie; because, at this stage, PHP has no idea whether your browser will accept cookies, it also rewrites all URLs contained in the page to include a PHPSESSID= parameter. 3. Your browser displays the page, and sets the cookie. 4. You click a link to get the next page -- in addition to sending a request for the URL containing the PHPSESSID= parameter, your browser also sends the newly-set PHPSESSID cookie. 5. PHP responds with the new page, but, because it has received the PHPSESSID cookie in the previous step it now knows your browser is accepting cookies and does not bother to do any URL rewriting. 6. None of the URLs in the new page have the PHPSESSID= parameter appended -- transmission of the session id is now solely via the PHPSESSID cookie. Various things can influence this behaviour: - If your browser is not accepting cookies, URL rewriting will always occur and you will continue to see PHPSESSID= parameters appended. - If session.use_trans_sid is not set, PHP will do no URL rewriting but will attempt to use cookies (if enabled) -- if your browser doesn't accept cookies, sessions will fail to work (unless you manually append PHPSESSID= parameters where needed -- the SID built-in constant is provided for this). - If session.use_cookies is not set, PHP will not even attempt to use a cookie for the session id. - If session.use_only_cookies is set, PHP will use *only* cookies to store the session id -- again, if your browser is not accepting cookies, sessions will not work. As you can see, there are many ways of setting this up, with a few subtle nuances -- and some of the combinations don't actually make much sense (use_trans_sid=1 and use_only_cookies=1, for instance). Note that you *can* set it up so that PHP does no automatic PHPSESSID setting at all (use_trans_sid=0 and use_cookies=0) -- then it's up to you to manually append the PHPSESSID= parameter to all appropriate URLs.

Various things can influence this behaviour: - If your browser is not accepting cookies, URL rewriting will always occur and you will continue to see PHPSESSID= parameters appended. - If session.use_trans_sid is not set, PHP will do no URL rewriting but will attempt to use cookies (if enabled) -- if your browser doesn't accept cookies, sessions will fail to work (unless you manually append PHPSESSID= parameters where needed -- the SID built-in constant is provided for this). - If session.use_cookies is not set, PHP will not even attempt to use a cookie for the session id. - If session.use_only_cookies is set, PHP will use *only* cookies to store the session id -- again, if your browser is not accepting cookies, sessions will not work. As you can see, there are many ways of setting this up, with a few subtle nuances -- and some of the combinations don't actually make much sense (use_trans_sid=1 and use_only_cookies=1, for instance). Note that you *can* set it up so that PHP does no automatic PHPSESSID setting at all (use_trans_sid=0 and use_cookies=0) -- then it's up to you to manually append the PHPSESSID= parameter to all appropriate URLs.

Re: [PHP] url rewriting within sessions - confused newbie needs help
Mike, I hope you mean session_start(). Yes, I did. Getting a bit dyslexic nowadays. Well, you would, because PHP would use the value from the PHPSESSID= URL parameter. ... except that on the second call, the url (as displayed by the browser) does not contain the PHPSESSID parameter, yet I am still able to retrieve the session variables correctly ... My immediate reaction to this is that session.use_cookies must be set to 0 (or Off) in your php.ini (or equivalent). Have you checked this? If it looks correct, what does a phpinfo() page show? php.ini contains the following settings: [Session] session.save_handler = files session.save_path = /tmp session.use_cookies = 1 session.name = PHPSESSID session.auto_start= 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.serialize_handler = php session.gc_probability= 1 session.gc_maxlifetime= 1440 session.referer_check = session.entropy_length= 0 session.entropy_file = session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 1 url_rewriter.tags = a=href,area=href,frame=src,input=src,form=fakeentry In phpinfo(), the local value matches the master value for all entries, and match the entries in php.ini. I appreciate that this issue isn't a big deal - but I had hoped to understand php well enough to tell the difference between a bug and a feature. If it would help, I could send you the url for the page?

RE: [PHP] URL Rewriting
Hi Bill, I've been using PHP for a couple of years now and only recently (since upgrading to RH7.3) began to experience an odd problem. When navigating around my site or when I run HT://Dig across it the links are suddenly being rewritten back as http://my.dom.com/some_page?PHPSESSID=the_id_string. I haven't changed my coding between releases so evidently whatever I've been doing with session variables all along is suddenly behaving differently between releases. Your new installation looks like it has the enable_trans_sid option turned on: this option governs whether PHP will transparently rewrite links for users without cookies - htdig is one of these presumably ;-) You'll find that your forms have a new input type=hidden field as well, containing the session ID. It can be turned off in php.ini, but I think this might break sessions for non-cookie-accepting users (not sure).
