PHP has the exec function. exec('whoami') returns the name of the user who is running the web server (e.g. apache/root/fred). However commands executed with exec() (running as fred) do not behave the same as command executed from a shell (e.g. SSH) session. When you login via SSH, your shell (e.g. bash) instantiates a number of environment variables that shape the context in which you run commands.

Here's how to show the contents of a object in Javascript

function concatObject(obj) {
  str='';
  for(prop in obj)
  {
    str+=prop + " value :"+ obj[prop]+"\n";
  }
  return(str);
}

It's been a hectic year but along the way we've found a bit of time to concentrate on our own website. Lightenna.com has just been relaunched as a broadband website. We're always interested in hearing your feedback, so if you feel like it get in touch.

Demand explodes for Lightenna's Drupal services

Drupal's popularity has been steadily growing over the last 12 months, and it was a little over a year ago that Lightenna got involved and started delivering high-quality Drupal sites.

In recent weeks we've seen demand shoot up as more and more users become familiar with this content management system and aware of just how powerful it is.

We're gearing up to deliver even more engaging websites for our clients, using broadband content to make your site stand out.

This 3D test is a spin around an Audi R8. It's downloadable in high definition (720p) in DivX format. We're currently looking at 3D, amongst a number of other technologies, as a device to better get your message to your clients.

What I think of.com is a free tool to facilitate online review, feedback and sign-off.

Users can leave notes literally on top of webpages.

The site is currently in beta after nearly 15 months development. There's still a lot of work to do, but the site clearly illustrates the concept and we're looking forward to gathering feedback from users to make it even better.
