<p class="verinfo">(PHP 5 >= 5.3.0)</p>
<p class="para">
Without any namespace definition, all class and function definitions are
placed into the global space - as it was in PHP before namespaces were
supported. Prefixing a name with <em>\</em> will specify that
the name is required from the global space even in the context of the
namespace.
