There is *definately* a problem in PHP 4.0.6 with classes, inheritance, and
included/required files. Here is an example:
// ======================
// test.php:
<?php
include("children.php");
?>
// ======================
// ======================
// children.php
<?php
include_once("parent.php");
class Child2 extends Child1
{
}
class Child1 extends Parent
{
}
?>
// ======================
// ======================
// parent.php
<?php
class Parent
{
}
?>
// ======================
You can try this out for yourself and see what I mean. If you bring up "test.php" in
your browser, you should receive this error:
Fatal error: Class child2: Cannot inherit from undefined class child1
Why does this happen, even though all files are being included correctly? Well, I
know one way of preventing the error, and that is by re-ordering the classes in
"children.php" so that Child1() is listed first. This removes the error, **however**,
if the Parent() class is NOT in a separate file, and is actually part of the same file
(i.e. "children.php"), the order of the class definitions does NOT matter. Why is
this?
