#29044 [Opn->Fbk]: compact function doesn't take account of infinitly recursive arrays

ID: 29044 Updated by: helly@php.net Reported By: tomas_matousek at hotmail dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash -Operating System: WinXP +Operating System: * PHP Version: 5.0.0RC3 New Comment: Nothing much we could do about it. Detecting a recursion at the same level, as in your example, is easy but detecting multi-level recursion is very hard. Also it would slow down the function very much and require lots of memory when it is used with multi level arrays. Maybe we can disallow array references or something like that.
