Classes must be defined in order. They can be in different order if they are in same file though. (Zeev can explain this better :) Reclassified as documentation problem as this isn't explained anywhere. --Jani ------------------------------------------------------------------------ [2001-09-11 01:18:21] [EMAIL PROTECTED] Just wondering if there has been any progress on this report? Thanks. ------------------------------------------------------------------------ [2001-09-06 02:11:38] [EMAIL PROTECTED] 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? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=13165&edit=1
