Bug Type: Unknown/Other Function
Operating System: Debian Kernel 2.2.20-idepci
PHP Version: 5.0.0RC2
New Comment:
All, I appreciate your assistance and your contributions to PHP.
ahh! So the behavior change is that instance functions are treated as
static functions by call_user_func.
IMHO, I believe that such behavior is fundamentally disconnected from
the perpetrated behavior of accepted practices as set out by Zeev's
book and other documentation.
However, this lets me move forward with my work.

The behavior that's new in PHP 5 isn't the inability to
call a method by call name instead of instance. It's
that if you do so, PHP treats it as a static method
call. When a static method is invoked in PHP 5, you
cannot reference $this because it no longer exists and
was never meaningful in the first place.

darned the errant cut and paste.
The previous comment should have begun in a neutral questioning tone of
"So, is this ..." ...

o then this behavior is new for PHP5?
I ask becuase while the online manual seems slient on invocation by
class name, the examples, behavior of PHP4, and the 3rd Edition (for
PHP5) of Core PHP by Zeev Suraski and Leon Atkinson seem to allow
invocation by class name instead of instance.
The books Listing 11.78 actually uses a call by class name. There is
no indication in the eratta this was not the case.

This is not a bug, the error message here is totally correct as there
is no instance of this class in your script, so you can't access $this
here.

Description:
------------
PHP4 allowed one to call a function using call_user_func by passing in
an array containing the class name and function name as strings.
In PHP5RC1 and PHP5RC2, I have found the function is getting called.
However, using $this-> within the function triggers a fetal error.
My appologies, I was not sure what the best "Type" for this was, or if
I'm crazy and doing something bone head wrong.
Reproduce code:
---------------
class test_call_user_func
{
var $created = "false";
function __construct()
{
$this->created = "true";
}
function isCreated()
{
$ret = $this->created;
return $ret;
}
}
$function = array('test_call_user_func', 'isCreated');
print ("I have a return of isCreated [" . call_user_func($function) .
"]" );
Expected result:
----------------
I have a return of isCreated [true]
Actual result:
--------------
Fatal error: Using $this when not in object context in
/home/vfabello/workspace/loki/root/test3.php on line 16
