cómo llamar a clases de funciones globales desde el espacio de nombres PHP

Is there any way how to avoid to using so often backslash ?

Now if i'm using namespace and calling something global inside it i have to use backslash:

namespace foo;
$a = new \my\name(); // instantiates "my\name" class
echo \strlen('hi'); // calls function "strlen"
$a = \INI_ALL; // $a is set to the value of constant "INI_ALL"

in that case code inside namespace become really ugly, is there any way how to avoid that situation ???

The example was taken from that url: http://www.php.net/manual/en/language.namespaces.faq.php

But my problem in that, if I need call some built in class from namespace i have to use backslash in front of the name, can I somehow avoid it ?

You do not need to prefix every built-in function of PHP. -

constants and functions from the global namespace do not have to be prepended with a backslash. PHP will fallback to the global namespace for those on it's own. There is a whole chapter in the PHP manual explaining this:

Inside a namespace, when PHP encounters a unqualified Name in a class name, function or constant context, it resolves these with different priorities. Class names always resolve to the current namespace name. […] For functions and constants, PHP will fall back to global functions or constants if a namespaced function or constant does not exist.

Yep, and what should I do with exceptions, for instance, or any other buil in classes ? like memcached etc... ? it does not work if I call it without backslash even php builded extension class. It means in code there are a lot of back slashes :( - user1016265

@user1016265 an exception is neither a function, nor a constant but a class and the manual clearly states that class names resolve to the current namespace name so you have to prepend them or alias them on top of your script. - Gordon

You do however need to add the backslash infront of "native" class like \Exception, \Memcached or you can choose to add: use \Exception; to the top of your file. Then you can use new Exception('..'); without the backslash. - Michael

@Gordon that PHP manual fully crap. What solution do you think better, what Michael suggested or manual described ? My opinion Michael suggestion better in 100% - user1016265

@user1016265 what Michael describes is the same that I describe is the same that the Manual describes. We all describe the same thing because we bothered to read and understand the manual. - Gordon
