#22047 [WFx->Asn]: PHP pollutes the namespace w/ (what looks like) its grammar tokens

ID: 22047 Updated by: derick@php.net Reported By: szepe@pinerecords.com -Status: Wont fix +Status: Assigned Bug Type: *General Issues Operating System: Linux PHP Version: 4.3.0 -Assigned To: +Assigned To: derick New Comment: That is a good idea, thought it did that. Assigned. Previous Comments: ------------------------------------------------------------------------ [2003-02-04 10:09:56] szepe@pinerecords.com Hmm. I'm convinced PHP should at least file a big fat warning upon any attempted redefinition of a reserved constant name, instead of ignoring the instruction entirely. Identifiers such as T_LIST are very often used in enums. ------------------------------------------------------------------------ [2003-02-04 10:05:43] derick@php.net The tokenizer extension needs those, and changing it now would be breaking all scripts that make use of it. So there is little we can do here... Derick ------------------------------------------------------------------------ [2003-02-04 10:02:59] szepe@pinerecords.com Since 4.3.0, PHP defines constants that are suspiciously similar to its grammar tokens. These cannot be redefined and should clearly be considered namespace pollution. For instance, the following example: <? echo T_LIST, ", ", T_STRING, "\n"; ?> will output '345, 304'. Needless to say, this broke one of my PHP creations horribly. :) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22047&edit=1
