Bug #7765 Updated: not OO until automatic class destructor is added

ID: 7765 Updated by: jimw@php.net Reported By: shelby@DownloadFAST.com -Status: Open +Status: Closed Bug Type: Feature/Change Request Operating System: * PHP Version: 4.0.3pl1 New Comment: ZE2 has destructors. Previous Comments: ------------------------------------------------------------------------ [2001-10-23 14:42:22] shelby@DownloadFAST.com Thank you for keeping my feature request alive. If I remember the discussions correctly, the implementation issue boiled down to the fact that PHP does not kill local variables at function or block termination (for speed reasons I believe). In order to properly implement a destructor, the reference count for a variable needs to be decremented as the block scope of the declaration is exited. I had suggested that this be a compile time flag, because correct program behavior is to do the reference decrements on block exit. For those of us who want every possible tool to illuminate bugs (e.g. error_reporting( E_ALL)), this just adds another level of error checking on use of such constructs as global references on local variables, etc. Again, perhaps this is not the main focus of PHP, but nevertheless I think it would be helpful option for developers who are writing huge OO sites with PHP. It seems the incidence of such has increased greatly since I first made this report. BTW, I do not know how my original comments got deleted. I hope my memory of the issues is correct herein. Apologies if I am mistaken. Please take my comments constructively. ------------------------------------------------------------------------ [2001-10-23 13:54:34] shelby@DownloadFAST.com Thank you for keeping my feature request alive.
