Essentially, I have run into this problem: I am unable to
use the '::' operator to define a class within a namespace
or inherit from a class within another namespace (I am
using 4.3.0-alpha2).
Example:
<?
class Boo {
class Scream {
}
}
class Boo::Ahh extends Boo::Scream {
}
?>
This will generate a "expecting ''{'' on line 7" parser
error (the "class Boo::Ahh ....." line). Similarly, "class
Biff extends Boo::Scream {}" and "class Biff::Ahh extends
Boo {}" (or any other definitions in these forms) will
generate the same error. It appears to me that any class
definitions that use the :: operator and the extends
clause will generate this error.
I have found this to be a problem that is particularly
annoying, as I am developing a set of library classes that
reside within specific namespaces, in seperate files. For
example, I would like to be able to create a namespace
"Foo" containing class "Bar" and its child class "Biff",
both in seperate files so scripts not utililizing "Biff"
need not load it.

The problem exists in the internal handling of :: within classnames. Here is another example of the same problem in a different context. In this case...when using the classname within a variable, PHP isnt able to find the class. <? class App { function CreateObject($classname) { return new $classname; } } class App::Client { function __construct() { echo 'In App::Client constructor'; } } class Client { function __construct() { echo 'In Client constructor'; } } App::CreateObject('Client'); App::CreateObject('App::Client'); ?>As namespaces have been rewritten entierly since this bug was reported, I think what's still left of this is: namespace foo { class bar { } } $name= 'foo::bar'; $o= new $name(); Results in: Fatal error: Class 'foo::bar' not found eval('$o= new '.$name.'();'); is ugly but works.
