Bug #76020 [Opn->Nab]: Not fully implemented class only generates fatal without exception

Edit report at https://bugs.php.net/bug.php?id=76020&edit=1 ID: 76020 Updated by: nikic@php.net Reported by: elibyy at gmail dot com Summary: Not fully implemented class only generates fatal without exception -Status: Open +Status: Not a bug Type: Bug -Package: PHP Language Specification +Package: Scripting Engine problem Operating System: Win/Nix PHP Version: 7.0.27 Block user comment: N Private report: N New Comment: The fatal error to exception conversion occurs on a best-effort basis. Not every place can easily throw an exception instead of a fatal. This is one of them. If the technical issues are resolved at some point in the future, this will be changed to throw as well. PS: The exception would occur at the point of the class declaration, not at the point of instantiation. As such, your particular example code would not work in any case.
