Please some one explain to me how it works and how to do it.
PHP has a function just for this: parse_url().
$parts = parse_url('domain.com/THESTRING');
$path = $parts['path'];
That wil get the part that you want
Could also use below if you want the current URI:
$_SERVER["REQUEST_URI"]
Yet another way:
echo strstr(str_replace('://', '', 'domain.com/THESTRING'), '/'); // THESTRING
EDIT: This should get you started.
Make sure your server support Mod_Rewrite
I opened a .htaccess in the public_html directory.
Then turned on the Mod_Rewrite by this command:
RewriteEngine on
Then I write a new law:
RewriteRule (.*)\.html$ index.php?link=$1
Thats bicycly mean that every url that ends with .html will redirect to index.php
Then in index.php I get the URL link

I am trying to get the value after the / in a URL in PHP.
I have tried using $_GET['va'], but this only works for the following,
http://localhost:8080/default?va=xxx
What I'm trying to get is this,
http://localhost:8080/default/xxx
How do I get the xxx value after a / in PHP.
Any help is greatly appreciated.
Edit
Thanks to everyone who answered, I wasn't very clear in stating what I wanted. It appears what I was looking for is known as a pretty URL or a clean URL.
I solved this by following Pedro Amaral Couto's answer.
Here is what I did;
I modified my .htaccess file on my Apache server, and added the following code.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+)$ default.php?page=$1
RewriteRule ^([a-zA-Z0-9]+)/$ default.php?page=$1
Then I modified my default.php file to GET ['page']
<?php
echo $_GET['page'];
?>
And it returned the value after the "/".
You want to make what is called "pretty URLs" (and other names).
You need to configure the HTTP server appropriately, otherwise you'll get a 404 error. If you're using Apache, that means you may configure .htaccess with RewriteEngine module activated. You also need to add regular expressions.
There's already a question in StackOverflow concerning that subject:
Pretty URLs with .htaccess
Here are another relevant articles that may help:
http://www.desiquintans.com/cleanurls
https://medium.com/#ArthurFinkler/friendly-urls-for-static-php-files-using-htaccess-3264e7622373
You can see how it's done in Wordpress:
https://codex.wordpress.org/Using_Permalinks#Where.27s_my_.htaccess_file.3F
If you follow those, you won't need to change the PHP code, you may use $_GET to retrieve "xxx".
You are looking for: $_SERVER['REQUEST_URI']
The URI which was given in order to access this page; for instance, '/index.html'.
basename(parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH));
So the $_GET global variable is for parsing the query string.
What you're looking for is the $_SERVER['REQUEST_URI'] global variable:
$url = $_SERVER['REQUEST_URI'];
$url will now contain the full URL of your path. You'll need to use explode('/', $url) to break up that full URL into an array of little strings and parse it from there.
Example:
$pieces = explode('/', $url);
// this will get you the first string value after / in your URL
echo $pieces[0];
You can do in 2 ways.
1- do these steps
Get URL
Explode by /
Get Last element of array
2- Add .htaccess and map that value for some variable
RewriteRule ^default/(.*) page.php?variable=$1
and you can get $_GET['variable']
so my index.php can be this:
<?php
$restOfURL = ''; //idk how to get this
print $restOfURL; //this should print 'FOO', 'VAR3', or any string after the domain.
?>
You want to use,
<?php
$restOfURL = $_SERVER['REQUEST_URI'];
// If you want to remove the slash at the beginning you can use ltrim()
$restOfURL = ltrim($restOfURL, "/");
?>
You can find more of the predefined server variables in the PHP documentation.
Update
Based on your comment to the question, I guess you're using something like mod_rewrite to rewrite the FOO, etc and route everything to just one file (index.php). In that case I would expect the rest of the URL to already be passed to the index.php file. However, if not, you can use mod_rewrite to pass the rest of the URL as a GET variable, and then just use that GET variable in your index.php file.
So if you enable mod_rewrite and then add something like this to your .htaccess file,
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]
Then the rest of the URL will be available to you in your index.php file from the $_GET['url'] variable.
Reading $_SERVER['REQUEST_URI'], as everybody has pointed out, can tell you what the URL looks like, but it doesn't really work the way you want it unless you have a way to point requests for me.com/VALUE1 and me.com/VALUE2 to the script that will do the processing. (Otherwise your server will return a 404 error unless you have a script for each value you want, in which case the script already knows the value...)
Assuming you're using apache, you want to use mod_rewrite. You'll have to install and enable the module and then add some directives to your .htaccess, httpd.conf or virtual host config. This allows you make a request for me.com/XXX map internally to me.com/index.php?var=XXX, so you can read the value from $_GET['var'].
$var = ltrim( $_SERVER['REQUEST_URI'], '/' )
http://www.php.net/manual/en/reserved.variables.server.php
Just by looking at the examples, i think you are looking for the apache mod_rewrite.
You can apply a RewriteRule via an htaccess file, for example:
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^([\w]+)$ /checkin.php?string=$1 [L]
For example this url http://foo.com/aka2 will be process by checkin.php script and will have "aka2" passed as $_GET['string'].
Make no mistake, the URL will still be visible in the browser as http://foo.com/aka2 but the server will actually process http://foo.com/checkin.php?string=aka
mod_rewrite documentation
$_SERVER['REQUEST_URI']
Why bother with all the fancy mod_rewrite/query_string business? There's already $_SERVER['PATH_INFO'] available for just such data.
ok assume i have php page
has this name name.php?get= and has get varible named get
ok
how i can make it appear like that name?get=
If you are using apache, mod_rewrite is one way to go. There is a whole bunch of mod_rewrite tricks here.
I'd seriously reconsider before using (or overusing) mod_rewrite.
In almost all of my projects I use a simple mod rewrite in the .htaccess:
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^.*$ ./
AddHandler php5-script .php
This tells the server to forward all pages to / (index.php) unless a file otherwise exists.
In the root directory I have a folder called "views" with all of the pages that I use. E.g. the file used for /home would actually be /views/home.php. However, in the index.php I have a script that parses the user's url, checks for the file, and includes that.
$page = substr($_SERVER['REQUEST_URI'], 1);
if(!$page) :
header("Location: /home");
if(file_exists("views/$page.php")) :
include "views/$page.php";
else :
include "views/$page.php";
endif;
This creates a variable called $page that stores the value of everything in the URL after the domain name. I use a substr() function on the Request URI to get rid of the trailing forward slash (/) on the URL.
If the variable is empty, for example if the user is simply at http://example.com or http://example.com/ then it forwards them to /home, where the script then checks for the home.php file inside of the views folder. If that file exists, it includes it, and displays it to the user.
Else, the script will simply include the 404 page telling the user that the file doesn't exist.
Hopefully this helps you, and if you need any further explanation I'd be happy to help!
I think you're wanting to re-write the URL client-side, which would include mod_rewrite.
In the route of your website, create a file called .htaccess and place the following code in it:
RewriteEngine on
RewriteRule ^name?get=(.*) /name.php?get=$1
Now when you type http://www.example.com/name?get=something, it will actually map to http://www.example.com/name.php?get=something transparently for you.
As far as i could understand your question, you can not strip the file extension because otherwise it will not run. In other words, you can not change:
name.php?get=
into
name?get=
But if you mean to create links with query string values that you can put them in hyperlinks in this way:
Click here !!
If you're looking to create links using a variable '$get', then you can create the link like this:
<a href="name.php?get=$get>Link</a>
Or if you want to get the value of the query string variable, you can use this:
$get = $_GET['get']
suppose we have the following PHP page "index.php":
<?
if (!isset($_GET['req'])) $_GET['req'] = "null";
echo $_SERVER['REQUEST_URI'] . "<br>" . $_GET['req'];
?>
and the following ".htaccess" file:
RewriteRule ^2.php$ index.php?req=%{REQUEST_URI}
RewriteRule ^1.php$ 2.php
Now, let's access "index.php". We get this:
/index.php
null
That's cool. Let's access "2.php". We get this:
/2.php
/2.php
That's cool too. But now let's have a look at "1.php":
/1.php
/2.php
So... we ask for "1.php", it silently redirects to "2.php" which silently redirects to "index.php?req=%{REQUEST_URI}", but here the "%{REQUEST_URI}" seems to be "2.php" (the page we're looking for after the first redirection) and the $_SERVER['REQUEST_URI'] is "1.php" (the original request).
Shouldn't these variables be equal? This gave me a lot of headaches today as I was trying to do a redirection based only on the original request. Is there any variable I can use in ".htaccess" that will tell me the original request even after a redirection?
Thanks in advance and I hope I've made myself clear. It's my first post here :)
I'm not sure whether it will meet your needs, but try looking at REDIRECT_REQUEST_URI first, then if it's not there, REQUEST_URI. You mention in your comment to Gumbo's answer that what you're truly looking for is the original URI; REDIRECT_* versions of server variables are how Apache tries to make that sort of thing available.
Just change the order of the rules and it works:
RewriteRule ^1\.php$ 2.php
RewriteRule ^2\.php$ index.php?req=%{REQUEST_URI}
Or use just one rule:
RewriteRule ^(1|2)\.php$ index.php?req=%{REQUEST_URI}
Well I guess I solved the problem. I used the %{THE_REQUEST} variable which basically contains something like this: "GET /123.php HTTP/1.1". It remains the same even after a redirection. Thanks everyone for your help! :)
Let' say for example one of my members is to http://www.example.com/members/893674.php. How do I let them customize there url so it can be for example, http://www.example.com/myname
I guess what I want is for my members to have there own customized url. Is there a better way to do this by reorganizing my files.
You could use a Front Controller, it's a common solution for making custom URLs and is used in all languages, not just PHP. Here's a guide: http://www.oreillynet.com/pub/a/php/2004/07/08/front_controller.html
Essentially you would create an index.php file that is called for every URL, its job is to parse the URL and determine which code to run base on the URL's contents. So, on your site your URLs would be something like: http://www.example.com/index.php/myname or http://www.example.com/index.php/about-us or http://www.example.com/index.php/contact-us and so on. index.php is called for ALL URLs.
You can remove index.php from the URL using mod_rewrite, see here: http://www.wil-linssen.com/expressionengine-removing-indexphp/
Add a re-write rule to point everything to index.php. Then inside of your index.php, parse the url and grab myname. Lookup a path to myname in somekinda table and include that path
RewriteEngine on
RewriteRule ^.*$ index.php [L,QSA]
index.php:
$myname = $_SERVER['REQUEST_URI'];
$myname = ltrim($myname, '/'); //strip leading slash if need be.
$realpath = LookupNameToPath($myname);
include($realpath);
create a new file and change it name to (.htaccess) and put this apache commands (just for example) into it :
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^profile/([0-9]*)$ members.php?id=$1
You must create a rewrite rule that point from http://www.example.com/myname to something like http://www.example.com/user.php?uname=myname.
In '.htaccess':
RewriteEngine on
RewriteRule ^/(.*)$ /user.php?uname=$1
# SourceURL TargetURL
Then you create a 'user.php', that load user information from 'uname' GET variable.
See from your question, you may already have user page based on user id (i.e., '893674.php') so you make redirect it there.
But I do not suggest it as redirect will change the URL on the location bar.
Another way (if you already have '893674.php') is to include it.
The best way though, is to show the information of the user (or whatever you do with it) right in that page.
For example:
<?phg
vat $UName = $_GET['uname'];
var $User = new User($UName);
$User->showInfo();
?>
you need apache’s mod_rewrite for that. with php alone you won’t have any luck.
