#13568 [Opn]: PHP3 semantics have been retained for nested functions

ID: 13568 Updated by: hholzgra@php.net Reported By: alvarez@st-oneline.net Status: Open -Bug Type: Scripting Engine problem +Bug Type: Documentation problem -Operating System: Linux +Operating System: * PHP Version: 4.10 New Comment: the new semantics that allows calling functions prior to their definition only works for functions defined in a global scope as soon as a function definition is within a conditional block or nested within another function the new function cannot be created at parse time as it is not known yet wether the condition will be met or the surrounding function ever called, so these functions are created at runtime instead when execution reaches this part of the code so it is rather obvious that you can't call such a function ahead of it's definition well, maybe not *that* obvious, reclassified as documentation problem ...
