API PHP Create-Domain Always Exit Status 256


I want to create a php program to automatically create virtual-server and sub-server on Virtualmin Server. Here is my code

<?php //init curl and set options $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://sub.server.com:10000/virtual-server/remote.cgi'); curl_setopt($ch, CURLOPT_USERPWD, 'root:rootpass'); //using self signed ssl cert, so dont verify curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_TIMEOUT , 300); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_POST, TRUE); //set command to execute here // $param = [ 'program' => 'create-domain', 'domain' => 'sub.domain.com', 'pass' => '123456', 'web' => '', 'dir' => '', 'unix' => '' ]; curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($param)); //execute curl request $result = curl_exec($ch); curl_close($ch); //see result echo $result; ?>

When I execute that code on a web browser, the new domain successfully created on the server, but the code always return a message “You are already hosting this domain” with exit status of 256. Does it should return the Exit Status : 0, instead of 256?

If I execute using wget code as on Virtualmin example on command line, it works perfectly with Exit status : 0.
Any idea how to solve this?
