I can't explain it better than to show you my thread
Environments: PHP 4.1.2 and 4.3.2
Scenario:
I have a script ../classes.inc.php which serves as a "JAR" file of PHP
classes that pertain to the entire application at application-level
scope. The script consists of about 25 different classes, of which
any class that extends OptionsView fails and produces this error:
Fatal error: Class fooview: Cannot inherit from undefined class
optionsview in /classes/classes.inc.php in line 2836
Here is code that consists of line 2836:
[PHP]
class AlbumOptionsView extends PaginationView { // THIS ONE IS JUST
FINE!
}
class FooView extends OptionsView { // BOMBS THIS IS LINE 2836
}
class OptionsView extends PaginationView {
}
class BlahView extends OptionsView { // THIS ONE IS JUST FINE
}
class Blah2View extends PaginationView { // THIS ONE IS FINE TOO!
}
class PaginationView extends View {
}
[/PHP]
However, if any class exists *physically placed after* OptionsView in
the script, and it extends OptionsView, everything is ok.
NOTE: This does not occur with any other class. If any class extends
any other class in the same script, no matter where it's placed,
everything is just fine.
I went so far as to literally strip out all code from OptionsView - to
no avail, same error.
