PHP question

[Simran]

Hello,
How we create Subdomains using PHP?

Thanks

I am not sure I understand your question but normally you don't use PHP but the webserver (e.g. apache) to create subdomains, either using virtual hosts or (.htaccess) rewriterules.

php is incapable of creating subdomains unless of course you are using an api for a control panel such as cPanel.

If you want PHP to be able to do things and treat content differently depending on the subdomain used you need to do the following:-

add *.yourdomain.com as an alias in httpd.conf
add a wildcard dns entry for your domain into your dns server (most likely bind)
then use code such as:-

<?PHP
$domain = explode('.', $_SERVER['HTTP_HOST']);
$subdomain = $domain[0];
?>

$subdomain will then contain the subdomain used to access the page.

use this script to add new subdoamin in your cpanel account

subdomainform.php


<html>
<head>
<title>create a subdomain</title>
</head>
<body>
<form name="form1" method="post" action="addsubdomain.php">
<h1>create Sub Domains</h1>
Sub Domain Name : <input type="text" name="subdomain"><br />
<input type="submit" name="Submit" value="Submit">
</form>
</body>
</html>


==============================

addsubdomain.php
=============================

<?php

ini_set('display_errors', 1);

$host = "domainname.com"; // your domain name without the www
$port = 2082;
$path = "/frontend/x/subdomain/doadddomain.html?domain=".$_POST['subdomain']."&rootdomain=".$host; //or .dll, etc. for authnet, etc.

// these lines are changed
$cpaneluser = "username";
$cpanelpass = "pass";
$authstr = "$cpaneluser:$cpanelpass";
//****************************

// Setup the Auth String
$pass = base64_encode($authstr);

$fp = fsockopen($host, $port, $errno, $errstr, $timeout = 30);

if(!$fp){
//error tell us
echo "$errstr ($errno)n";

}else{

//send the server request

fputs($fp, "POST $path HTTP/1.1rn");
fputs($fp, "Host: $hostrn");
fputs($fp, "Authorization: Basic $pass rn");
fputs($fp, "Content-type: application/x-www-form-urlencodedrn");
fputs($fp, "Content-length: ".strlen($poststring)."rn");
fputs($fp, "Connection: closernrn");
fputs($fp, $poststring . "rnrn");

//*************************************
// Remove this to stop it from displaying the output fron the CPanel
//*************************************
//loop through the response from the server
/*
while(!feof($fp)) {
echo fgets($fp, 4096);
}

*/
while(!feof($fp)) { fgets($fp, 4096); }
//close fp - we are done with it
fclose($fp);
}

I believe Peter answered this question correctly by how the author phrased things, I believe he wanted to know about wildcard DNS.

Make sure you have you host configure apache to have wildcard DNS run for you
