this bug really shows how one person's bug is another person's
feature. :)
the syntax $a-method() allows you to call a static method of the
class that $a is an instantiated object of, something I find useful
for objects that contain static methods in a parent/child
inheritance hierarchy. Using $a-method(), I don't need to do
hackery to figure out which class $a is in order to call one of
its static methods. Consider the alternative:
?php
call_user_func_array(get_class($a), 'method', $args);
?
The above is the only alternative (save using reflection, which is
even more verbose and inefficient) to:
?php
$a-method($arg1, $arg1);
?
Which syntax do you prefer?
The big difference between php 4 and php 5 is that a method declared
as static does not have $this set. You'll get a fatal error, in
fact, if you try to use $this in a static method.
Why do you care so much about whether it's called with
class::method() or $this-method()? You can't have two methods with
the same name, one static and one non-static, so there is no
possibility of accidentally calling the wrong one.
If you are wanting absolutely perfect OO, there are plenty of
other languages that will provide exactly the straightjacket and
punishment you desire. If you want to code efficient, easy to
maintain, working programs, use PHP.

Derick, this is a bug (any Object Oriented logic).
There's something wrong in your static keyword implementation, at least
for methods that uses static keyword.
This my last call and this is my last example:
?php
class ExampleClass {
public $StaticExample;
public final function __construct(){
// bye bye public *parameter*
$this-StaticExample = create_function('$never', 'return
welcome
PHP5 ambiguity;');
}
public final static function StaticExample(){
echo StaticExample, br /;
}
}
$test = new ExampleClass();
ExampleClass::StaticExample();
exit($test-StaticExample());
?
What does static keyword mean for PHP 5 developers?
If this is an expected behaviour you should explain them in
documentation page.
Regards (I'll never open again this *bug*)

Hi,
i was talking with andrea yesterday evening and he was explaining me
that stuff.
I don't know if it is an expected behaviour or not, but i'm sure that
somewhere there is a problem!
Infact, if it is an expected behaviour the static keyword loss it
meanings and, probably, slowdown the php page compilation/execution, but
if it is normal documentation should be fixed because it says a totally
different stuff.
However, to get back to the problem, the manual says, as should be:
A member declared as static can not be accessed with an instantiated
class object
Because is a non sense say that something is static and after let to
the code to call it as non static

This cannot be an expected behaviour because in this way a static
method is exactly the same of a generic public method.
Static parameters aren't (correctly) usable with instances so why
static methods should be assigned?
If this is an expected behaviour please tell us what do You think
static keyword means and explain them correctly on documentation page.
