PHP - Trying To Change Url From Ip To Domain Name

hey guys im making a script where the user gets redirected...but im wanting to make sure the redirection is within the same domain and not being shipped off to another site when using ($_SERVER['HTTP_REFERER'])   now what im using seems to do the trick but im wondering if there is a better method of doing this?...i dont want to use regex either   thank you guys

<?php 

$match = strpos("http://127.0.0.1/login", $_SERVER['SERVER_NAME']);

if ($match && $match > 0 ||  $match === 0)
{
	echo "domain match";
}

?>

I know how to get an ip adress from a domain by using gethostbyname(), but I wanted to know if it was possible to get the domain name from the ip address.

As in a website address (example.com) has a ip address of xxx.xx.xxx.xxx

What I am trying to do is to get the 'example.com' domain name from the ip address.

Is this at all possible, if so, how can it be done?

Thanks in advance for any that helps out.

Hello everyone,

I have a site where the folders are set up in this arrangement:
Code: [Select]
                           _
ClientsFolder - client1 - | page-folder - pages are here (index.php)
                          |
                          | image-folder - images here
                          |
                          |_include-folder - style.css and database connections here
                                       
                           _
                client2 - | page-folder - pages are here (index.php)
                          |
                          | image-folder - images here
                          |
                          |_include-folder - style.css and database connections here


PageIncludeFolder - include pages here (index.inc.php)


The reason my folders are set up this way is because multiple clients will be using my site, but each client will have a customized sub-domain, yet all the code on the pages will be the same.  All of the pages for the clients site are placed in ClientsFolder/client1/page-folder.  Each page in this folder is a page that simply includes an entire page from the PageIncludeFolder.  For example:

ClientsFolder/client1/page-folder/index.php
and
ClientsFolder/client2/page-folder/index.php

are exactly the same, file, which simply has the following code:
Code: [Select]
<?php
include("../../../PageIncludeFolder/index.inc.php");
?>The reason for this is so that I can easily modify all the client sites by only modifying the files that are in the PageIncludeFolder. (Trying to work smarter, not harder!)

The images, style.css, and script.js files are called from the index.inc.php, which is included on the index.php page.

For example, style.css is located at ClientsFolder/client1/page-folder/include-folder/style.css.  So to link to the .css file, I have the following code in the index.inc.php file:
Code: [Select]
<link href="../include-folder/style.css" rel="sytlesheet" type="text/css" />
And images are linked using code similar to this:
Code: [Select]
<img src="../image-folder/image.jpg" />
Now, when I visit the index.php page by entering the entire url (http://www.mysite.com/ClientsFolder/client1/page-folder/index.php) everything works perfectly.
However, as I stated, each client is being set up with a sub-domain.  Client 1 has the sub-domain of http://client1/mysite.com, which is pointed to http://www.mysite.com/ClientsFolder/client1/page-folder/index.php.  When I try to visit client 1's site using the sub-domain, the index.inc.php page is included perfectly, but the images and the style.css files are not being linked.

I know this is kind of confusing, but as you can probably tell, I have spent many, many hours putting this together and now I need help to figure out what is wrong and why certain files are not linking properly ONLY when the page is visited using the sub-domain.  ANY help or suggestions are GREATLY appreciated!  Thanks everyone!

I have two questions:

1. Is it the best way to get the domain of a url by parse_url? or preg_match or str_replace can be better alternatives?

2. What is the best way to remove www from the domains? Note that the domain name itself may contain www too (like www.1www.com)

Thank for your attention 

i want to get all the domain name on the internet and put them into a database. is there a way to get this.

Hello

I am curious if it is even possible to get the domain when using iframes/frames?

eg. domain2 shows a file from domain1 in an iframe. Can domain1 grab domain name "domian2"?

Hi,

I am trying to see if the domain name in the string is in an array.

eg;

Code: [Select]
mystring='http://google.com/somethingelse';

myarray[]='google.com';
myarray[]='anotherdomain.com';
in this case return TRUE

Code: [Select]
mystring='http://phpfreaks.com/adir';

myarray[]='google.com';
myarray[]='anotherdomain.com';

in this case return FALSE

How would I do this?

Thanks,

-mme

Sorry if this is a stupid question 

http://www.dinksoftware.com/fig/index.php looks as it should with the php includes working.

However if you go to http://www.dinksoftware.com/fig or http://www.dinksoftware.com/fig/ the php includes don't work for some reason.

index.php
Code: [Select]
<?php session_start(); ?>
<?php include('header.php'); ?>
<?php include('topMenu.php'); ?>
<?php include('sidenav.php'); ?>


<div id="content">
<h3>Introducing 'The Business Sim'!</h3>

<?php $errorMessage1 = $_SESSION['errorMessage1'];
echo("$errorMessage1 <p>");
$_SESSION['errorMessage1'] = ""; ?>

The Business Sim is an online, free to play educational game currently under development. <strong>The first round of gameplay will commence in Q1, 2011. </strong><br />
<p>Have gameplay ideas/suggestions or any other comments? Want to help mould the game? </p>

<br/>

<?php include('footer.php'); ?>
</div>
</body>
</html>
header.php part
(no other  includes or anything in this)
Code: [Select]
<a href="index.php"><img src="header.png" alt="The Business Sim" width="550" height="100" border="0"/></a>
How do I fix this? I want http://www.dinksoftware.com/fig and http://www.dinksoftware.com/fig/ to work like it does when you go/fig/index.php etc.

I have a client, that wants an affiliate driven service, which is fine. However they want to offer the affiliates the ability to forward there own domains to the service and have that work as the initial affiliate id token. Now my question is. I know I can find what the domain is that the scripts I am writing run off of using $_SERVER['HTTP_HOST'] however I'm not to sure how that would work for a domain that is forwarded with a 301 or 302 redirect status and masked for use on the service I am building up. I want to say I could use $_SERVER['HTTP_REFERER']. But as I said I'm not to sure how thats going to work for a forwarded domain thats masked as its not part of the actual host conf files its landing on in the end.

Hopefully I am making sense with the above. So what would be my best choice of options to work with when handling a domain that will be masked and landing on another domain as it will be forwarded. I am only taking the inital landing with a domain and setting the tokens I need set for it to run as that affiliate and setting them in sessions and cookie and various other variables. But I guess I am just wondering which would be better for me to catch that inital landing with the domain thats forwarded.

HI,   I am triying to check a domain is valid or not using PHP. If the domian is not a valid one the name shoud be empty string.   So I tried using preg_match() and preg_replace(). But I couldn't get it to work.   This is my code sofar -

if (preg_match ('/^((?!-)[A-Za-z0-9-]{1,63}(?<!-)\\.)+[A-Za-z]{2,6}$/', $domain)) {
   $mydomain = $domain;
} else {
   $mydomain = preg_replace("/^((?!-)[A-Za-z0-9-]{1,63}(?<!-)\\.)+[A-Za-z]{2,6}$/", "", $domain);
}

When I am tring using valid and invalid domain name its always going to else part.   Eg: example.com       example.t.t.c   Hope somebody may help me out. Thank you.

What I'm trying to do is get my $_SESSION to work throughout my website. I'm quite new to PHP, so the PHP Manual didn't make much sense to me, so I thought I'd post here! ^^   I've got my login script under /session/ and I want it to be able to display your username on the homepage (/), but it only works inside /session/.   If you are wondering, I am using PHP-Login Advanced.   Thank you, - Connor!

Hi

I operate (example) www.joebloggs.com which is using PHP sessions to handle Logins, etc etc.

I also operate a separate site at www.joebloggs.com/NewSite which is entirely seperate from the site at www.joebloggs.com, even though there operating on the same Domain and Server.

My problem is, when a user logs out of www.joebloggs.com (Using session_destroy), it also destroys any session information associated with www.joebloggs.com/NewSite.

Is there any way to prevent this happening or am I going to have to rethink how I handle my sessions?

Scouring the internet (Ive quoted below) I think somebody mentioned using session_name() but I fail to see how it would be implemented?

Quote

To avoid problems with sessions you should use the session_name('myapplication') [ session_name({UNIQUE_APP_ID}) ].

The problem you are mentioning can occur in more simple situations where there is an administration panel and a sign-in form for the users of the web site.

If session_name is not used a signed-in user could have access to the admin. panel but this depends on the auth. scheme and mechanism you have implemented.

Let's say that I have domain called www.mydomain.com with SSL certificate. Through .htaccess I have set up the domain to force SSL at all times, so users will see https://www.mydomain.com/... I had this site and SSL for while and there are serveral external links linking to my site, but they are all (or most) in "SSL format" https://www.mydomain.com/... If I should cancel my SSL certificate (and remove force SSL in .htaccess) that will happen when those "SSL formatted" links get clicked on? I assume users will get "not trusted connection" message? Any way arround that? As far as I undersestand the "SSL" handshake takes place before .htaccess gets loaded, so I will not be able to force SSL off on the links.   Thoughts?
