#39567 [NEW]: Cannot find Class definition when there is one

[imkow at 163 dot com]

From: imkow at 163 dot com
Operating system: WinXp sp2+Apache2.2+Mod_PHP
PHP version: 5.2.0
PHP Bug Type: Class/Object related
Bug description: Cannot find Class definition when there is one

Description:
------------
Two files:
file1.php:
class A{}

file2.php�F
require("file1.php");
$obj=new B;
class B extends A{}

when runing file2.php, it throws a Fatal Error, saying Class B can't be
found in the line where "$obj=new B;" is.

But, in following code, things will just be fine:
class A{}
$obj=new B;
class B extends A{}


I use an official release of PHP 5.2.0 under windows. All mods are also
from Pecl.



Reproduce code:
---------------
//file1.php:

class A{}



//file2.php�F
require("file1.php");
$obj=new B;
class B extends A{}

Expected result:
----------------
nothing..

Actual result:
--------------
( ! ) Fatal error: Class 'B' not found in file2.php on line 2

Expected behaviour.
Class "B" cannot be declared in compile time, because class "A" is
declared in another file.
But in runtime, when you execute the line "$obj=new B;", the class "B"
doesn't exist yet.

do you mean that it's forbidden to write code like
within one file:
class A{}
$j=new B;
class B extends A{}

or code like:

$j=new B;
class B{}

is also forbidden.

But at this moment they all work fine in php. if those mentioned are
forbidden, maybe we should write something in the manual to clarify
this...

No, I didn't mean this.
I meant exactly what I said - there is no way to declare this class in
compile time, so it's declared in runtime.
And you get the error because you're trying to use the class which is
not yet declared.
Please keep this report a bogus. Thank you.

All right. but you people have to notice this is still a design fault
that should be addressed in somewhere. we php script developers don't
know much about php's internal structure. we can hardly distinguish
what is done in compile time and what is not. The problem isn't on the
manual where you can learn. So people will be used to write code like
this until something be pointed out or changed.
