> There are no namespaces, so functions often have prefixes to denote their source

Can somebody tell me, how namespaces work?

Say, without namespaces you would do it like this:

  function isBig($Number)
  {
   return ($Number>1000);
  }

  if (isBig(50)) echo '50 is big';

How would this look like when namespaces are used?
