Re: [PHP] variable scoping...
unfortunately, this doesnt seem to work. Rather, it works, but it doesnt
seem to work any differently than an include() (although you can't use
output buffering on it, so in that regard its different). It seems to pass
in all the variables and classes.
My other option, which I have been avoiding, is to rename the classes... not
all that hard really; and then for variables either rename them all, or do
this:
backupallglobalvariablesandunsetthem();
setvariablesthatscriptisexpectingtosee();
include("script");
unsetallvariablesnotinbackup();
restorebackupvariables();
and then repeat this for each script I'm trying to embed...
basicaly wrap each script/application in a clean "sterilized" php
envirionment.
I dont know how much overhead this would add. But it seems like the only
solution at this point. It just occured to me that this might actualy make
things more secure in a way since the parent script will totaly control what
variables get passed in..

The documentation is outdated. That restriction has been lifted as of PHP version 4.0.6.

but the virtual() documentation says you can't use it on a php script?

Re: [PHP] variable scoping...
I guess the only real way is to use virtual() in this case. That's a bit clunky as well, but it isn't quite as bad as going through CGI or all the way out to the port 80 level. -Rasmus On Fri, 12 Apr 2002, Aric Caley wrote: > Is it possible to keep the variable name-space separate between, say, two > files (one included into the other) to avoid name collisions?

[PHP] variable scoping...
Is it possible to keep the variable name-space separate between, say, two files (one included into the other) to avoid name collisions? I'm trying to get two scripts to work together on the same page. Each script defines some classes that have the same names but work differently (ex., class Template). All I need is to embed the output of one script into the other. Now, I could do this by just getting the output from a URL but that seems really inefficient. Or I could run the script from the CGI version of PHP using exec() but that also seems like it could be really slow and clunky. Is there some efficient way of doing this? It would be cool if you could just put the include() inside of a function and have all the classes and variable names be local inside that function but that didnt seem to work... plus the scripts explicitly access global variable names. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
