PHP version: 5.0.2
PHP Bug Type: Class/Object related
Bug description: Interfaces must appear before use
Description:
------------
I am not sure if this is a bug or a documentation issue, but if an
instance of a class is created before the Interface definition, the class
will be undefined. Although this is not directly covered in the manual,
it is inconsistent with functions, which can be reference before they are
defined.
./configure --with-apache=/usr/local/src/apache/apache_1.3.31
--with-libxml-dir=/usr/local/libxml2 --enable-calendar --with-openssl=/usr
--wi
th-pear --with-zlib --enable-ftp --with-bz2 --with-ldap --with-pdflib
--without-mysql --with-pgsql --with-pspell
Reproduce code:
---------------
$concreteType = new ConcreteType();
echo $concreteType->getText();
$c2 = new ContreteType2();
echo $c2->getText();
interface IType
{
public function getText();
}
abstract class AbstractType implements IType
{
}
class ConcreteType extends AbstractType
{
public function getText()
{
return "Hello World!!!";
}
}
class ConcreteType2 implements IType
{
public function getText()
{
return "Hello World!!!";
}
}
Expected result:
----------------
"Hello World!!!""Hello World!!!"
Actual result:
--------------
Fatal error: Class 'ConcreteType' not found in
/usr/local/apache/htdocs/bookallot/test.php on line 1
