Hi again,
The attached patches for PHP 5.3 and PHP 6 add in_class_exists(). The
function is intended to be used in __autoload(). The following test
script demonstrates its usage:
outputting:
bool(false)
bool(false)
bool(true)
bool(false)
The purpose is to allow an autoload handler to detect

Typehints continue working because of the restriction that applies to
this mechanism (see other mail(s)).

Of course. We are not changing the class declaration (compile-time) but
intercept the object creation (run-time).

Of course you can argue that the code was badly {designed|written} in
the example I showed and should be refactored before testing. More often
than not, though, you cannot do this (3rd party code, for example

Hi,
I spent a while tonight tinkering with the parser to try to figure out
how to allow it to use T_IMPORT as well as T_STRING for method names,
and quickly came to the conclusion that this causes way more trouble
than it is worth. However, in a moment of inspiration, I realized that

A while ago I posted a proposal to add support for tainted variables
to PHP, to alert programmers at run-time when they make the common
mistake of using uncleansed input with include, echo, system, open,
etc. A copy of the original post can be found on-line, for example,
at http://marc.info/?l=php-
Problem is the cost of setting up these, by registering implementations,
performing reflection and so on is expensive especially considering the
stateless nature of PHP.

I wouldn't actually recommend using such code. If you have
Foo::Exception just use Foo::Exception - it's short enough :)

Right. This does appear to be a "chicken or the egg" issue. Also,

What I want to use them for in PHPUnit is improving the Mock Objects
system.
Earlier this year, Johannes implemented class posing for PHP as follows:
This looks like factory pattern. What's wrong with implementing it as

However, to make this a viable mechanism that can be used in tools such

I definitely think it's worth another go. VS 2005 binaries are

Off the top of your head, what side effects do you already
anticipate, specifically? Also, I think Rich makes a good point about
the "free" Microsoft VS2005 Express Edition, but I don't know how much
more of a pain it would be to target that, or if it would cause
long-term issues or detriment
One important thing we forgot to discuss is to drop VS6 support fin
5.3 and finally move to VS2005.
As far as I know, non-CL builds are not supported at all right now, and
for CL builds it works with both - is there anything should be done for
VS2005?

Ideally think I'd prefer it finer grained...

$foo = new Foo();
