PHP cPanel Create Subdomain - php

Question

So I am trying to automatically create subdomains for my website using PHP. I tried the following code but it gives me a 301 error and redirects me to my cPanel login
function createDomain($domain) {
// your cPanel username
$cpanel_user = 'User';
// your cPanel password
$cpanel_pass = 'Pass';
// your cPanel skin
$cpanel_skin = 'paper_lantern';
// your cPanel domain
$cpanel_host = 'example.com';
// subdomain name
$subdomain = $domain;
// directory - defaults to public_html/subdomain_name
$dir = 'public_html/user_site';
// create the subdomain
$sock = fsockopen($cpanel_host,2083);
if(!$sock) {
print('Socket error');
exit();
}
$pass = base64_encode("$cpanel_user:$cpanel_pass");
$in = "GET /frontend/$cpanel_skin/subdomain/doadddomain.html?rootdomain=$cpanel_host&domain=$subdomain&dir=$dir\r\n";
$in .= "HTTP/1.0\r\n";
$in .= "Host:$cpanel_host\r\n";
$in .= "Authorization: Basic $pass\r\n";
$in .= "\r\n";
fputs($sock, $in);
while (!feof($sock)) {
$result .= fgets ($sock,128);
}
fclose($sock);
return $result;
}
Like I said it gives me a 301 error and redirects to example.com:2083 instead of just doing it in the code and not having me login to the cPanel manually. Any help would be greatly appreciated!

ANSWER:
After fiddling with my code I realized that port 2082 and port 2083 are the same except that 2082 has no https:// so I changed the port to 2082 and it worked!
CODE:
function createDomain($domain) {
// your cPanel username
$cpanel_user = 'User';
// your cPanel password
$cpanel_pass = 'Pass';
// your cPanel skin
$cpanel_skin = 'paper_lantern';
// your cPanel domain
$cpanel_host = 'example.com';
// subdomain name
$subdomain = $domain;
// directory - defaults to public_html/subdomain_name
$dir = 'public_html/user_site';
// create the subdomain
$sock = fsockopen($cpanel_host,2082);
if(!$sock) {
print('Socket error');
exit();
}
$pass = base64_encode("$cpanel_user:$cpanel_pass");
$in = "GET /frontend/$cpanel_skin/subdomain/doadddomain.html?rootdomain=$cpanel_host&domain=$subdomain&dir=$dir\r\n";
$in .= "HTTP/1.0\r\n";
$in .= "Host:$cpanel_host\r\n";
$in .= "Authorization: Basic $pass\r\n";
$in .= "\r\n";
fputs($sock, $in);
while (!feof($sock)) {
$result .= fgets ($sock,128);
}
fclose($sock);
return $result;
}

API 1 is now dead. Also passing your cpanel password through a non-secure connection (ie port 2082 instead of 2083) is a very bad idea. Next thing you know someone will have hijacked your cpanel account!
However, combining the codes given here for authentication and here for adding a subdomain, gives us the following script which seems to work just fine:
<?php
$cpanelsername = "example";
$cpanelpassword = "**********";
$subdomain = 'newsubdomain';
$domain = 'example.com';
$directory = "/public_html/$subdomain"; // A valid directory path, relative to the user's home directory. Or you can use "/$subdomain" depending on how you want to structure your directory tree for all the subdomains.
$query = "https://$domain:2083/json-api/cpanel?cpanel_jsonapi_func=addsubdomain&cpanel_jsonapi_module=SubDomain&cpanel_jsonapi_version=2&domain=$subdomain&rootdomain=$domain&dir=$directory";
$curl = curl_init(); // Create Curl Object
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,0); // Allow self-signed certs
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,0); // Allow certs that do not match the hostname
curl_setopt($curl, CURLOPT_HEADER,0); // Do not include header in output
curl_setopt($curl, CURLOPT_RETURNTRANSFER,1); // Return contents of transfer on curl_exec
$header[0] = "Authorization: Basic " . base64_encode($whmusername.":".$whmpassword) . "\n\r";
curl_setopt($curl, CURLOPT_HTTPHEADER, $header); // set the username and password
curl_setopt($curl, CURLOPT_URL, $deletedir); // execute the query
$result = curl_exec($curl);
if ($result == false) {
error_log("curl_exec threw error \"" . curl_error($curl) . "\" for $query");
// log error if curl exec fails
}
curl_close($curl);
print $result;
?>
The result should be something like this:
{"cpanelresult":{"func":"addsubdomain","event":{"result":1},"apiversion":2,"module":"SubDomain","data":[{"reason":"The subdomain “newsubdomain.example.com” has been added.","result":1}],"preevent":{"result":1},"postevent":{"result":1}}}
To delete the subdomain, run this query through the above script:
$deletesub = "https://$domain:2083/json-api/cpanel?cpanel_jsonapi_func=delsubdomain&cpanel_jsonapi_module=SubDomain&cpanel_jsonapi_version=2&domain=".$subdomain.'.'.$domain."&dir=$directory"; //Note: To delete the subdomain of an addon domain, separate the subdomain with an underscore (_) instead of a dot (.). For example, use the following format: subdomain_addondomain.tld
And to delete the directory, run this:
$deletedir = "https://$domain:2083/json-api/cpanel?cpanel_jsonapi_module=Fileman&cpanel_jsonapi_func=fileop&op=unlink&sourcefiles=$directory";

Noel's answer from 2018 more than likely won't work anymore, but if you've come here looking for how to use the Cpanel API to add a subdomain, start at this link to see the arguments accepted for the Cpanel API Ver 2 for the SubDomain module addsubdomain.
Below is an example that worked perfectly well for me.
$whmusername = "cpanel_username";
$whmpassword = "cpanel_password";
$subdomain = 'newsubdomain';
$cpanel_ip = 'IP_ADDRESS'; //ip of cpanel or your_domain.com
$domain = "your_domain.com";
$query = "https://".$cpanel_ip."2083/json-api/cpanel?cpanel_jsonapi_module=SubDomain&cpanel_jsonapi_func=addsubdomain&cpanel_jsonapi_apiversion=2&dir=/public_html/".$subdomain.".".$domain."/&rootdomain=".$domain."&domain=".$subdomain."";
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($curl, CURLOPT_HEADER,0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);
$header[0] = "Authorization: Basic " . base64_encode($whmusername.":".$whmpassword) . "\n\r";
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_URL, $query);
$result = curl_exec($curl);
curl_close($curl);
Note that if you want to see what Cpanel is returning as a response for $result, then place print $result; after curl_close($curl);
