[PHP] include/require inside of function
Is there anyway to include a file inside of a function and have the included stuff be global? For instance if I defined a class or a function in that include file, I want to be able to use that class outside of the function. On the documentation for include() a poster commented that it did indeed work like this, but my testing indicates it does not. Everything stays local to the function and goes away when the function ends. Is there a way? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] q: extract() and get_defined_vars()
am I assuming correctly that get_defined_vars() returns an array pretty much like the $GLOBALS array? If I call extract() inside of a function, then the variables it creates will be local to that function, correct? OK, so, is there a way to get extract() to define those variables as global, from within a function? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] q: extract() and get_defined_vars()
Yes it is, you must tell the function to treat the relevant variables as
globals though, here is a way of doing it:
function Foo(){
$theArray = array('var1'='testing', 'var2'='testing2');
foreach($theArray as $varname=$value){
global $$varname;
}
extract($theArray);
}
Foo();
echo $var1BR /$var2;
The above code outputs testingBR /testing2.
Pretty sneaky. But at this point, why bother with the extract() at all?
wouldn't this do the same thing:
function Foo(){
$theArray = array('var1'='testing', 'var2'='testing2');
foreach($theArray as $varname=$value){
$GLOBALS[$varname] = $value;
}
}
Which is what I am already doing...

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..

[PHP] Re: variable scoping...
Believe me, I'm not doing it on purpose. I'm trying to get two different script packages to play nice with each other and I want to keep the modifications at a minumum to make it easier to update the software. Specificaly I'm talking about a weblog package (phpslash) and forums package (phpbb), as well as a shopping cart (phpshop), initialy... maybe others as well. the class name problem isnt that bad, really. But there's global variables as well that need to be isolated. get/post vars, session vars, etc. My idea is to isolate each script, pass in the global vars that it expects to see. The overall, parent script would keep the variables for all the scripts under different names that dont conflict, converting them on entry to each script. Michael Virnstein [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... why do you have more than one class with the same name? would be easier using different names for different classes. or define a base class template and extend it in the files as desired, but give them unique names. how do you know later, which class does what in which way, when they have the same name. not very good imo.

Re: [PHP] curious - any phpshop/core users?
I've used PHPShop (the existing version, not the new core/commerce thing) to do one site. It's relatively easy to set up. I've had to do some modifications to it (namely, to make it use Payflow link, which works via HTTP requests; and adding dropdown menus on products to select color airtime rates -- its a pager site). It doesnt use templates exactly.. lots of HTML mixed with PHP. It definately could use some work. I havent really checked out the new version, since the commerce module is not released yet. I too am interested in modular systems. I'd like to see some sort of modular system that makes it easy to integrate together other systems which are not modular (or are modular but dont have the modules I want). For instance, I am using PHPSlash, YapBB (forums) and PHPShop but there's no easy way to make them all work together seamlessly, each one has its own authentication and session handling, its own database, etc. It would be nice to have a modular API that a completely stand alone application (like any of three I mentioned) could adhere to, that wouldnt limit the application in any demanding way, but would allow the application to also be a module working with any other compliant app. For instance, forums applications -- most that I've seen are stand alone systems. That's fine, but what if I want a forum as a module inside of something like PHPSlash or PHPNuke? I could take a forums package, probably do some pretty extensive mods to it like merging its database with my chosen parent app, replace its authentication and user system, etc, and make it a module. I've seen requests for such things, how about a module for PHPNuke?. Then what? What if you decide you really wanted it to work with PHPSlash instead? Start all over! Everybody has their own idea of how a modular system should be structured, generaly tailored for the application they want to use it in. Other people might not want to write their apps using that system because they dont want to be tied to it, or dont want all the other baggage of the application coming along for the ride when they just want the modularity part. phpshop core looks interesting but its not quite what I'm thinking of, I think. I am currently working on such a system that would make it easy to adapt existing applications to be modules with a minimum of modification. Its more of an API and a shell or glue rather than a complete application. I dont know if I am truly getting across my idea, but I thought I'd try to throw it out there for consideration.
