    exec('sudo -u ejabberd /usr/sbin/ejabberdctl register '.$username.' '.$node.' '.$password.' 2>&1',$output,$status);
    if($output == 0)
    {
        // Success!
    }
    else
    {
        // Failure, $output has the details
        echo '<pre>';
        foreach($output as $o)

Answer 1

<?php
    $username = 'tester';
    $password = 'testerpassword';
    $node = 'localhost';

    echo exec('sudo -u ejabberd /usr/sbin/ejabberdctl register '.$username.' '.$node.' '.$password.' 2>&1',$output,$status);
    die;
    if($output == 0)
    {
        // Success!
        echo "success";
    }
    else
    {
        // Failure, $output has the details
        echo '<pre>';
        foreach($output as $o)
        {
            echo $o."\n";
        }
        echo '</pre>';
    }
?>

I am using localhost in the $node, in the $node you can use your ip address as per the ip address you have configure in your configure.cfg.

I have the following error while running the above code

no tty present and no askpass program specified ; TTY=unknown ;

so the below link is the solution for the code below

sudo in php exec()

after executing the above link process

User tester@localhost successfully registered
