Re: [PHP] Global Variables
As far as I know, it's not true you can't use session variables if register_globals is off, the difference is that you must acces session variables using $_SESSION['variablename'], that's is an assurance that a session variable is a REAL session variable, and that it is not set using for example a faked form. hope this is a correct answer and it helps you, Giulio Il giorno 28/apr/05, alle 11:06 AM, Dan ha scritto: Hi all.

amc If no one has a better Idea I'll pass the connection through the constructor

amc Any thoughts? Would it make things easyer if the base class inherited all
amc nested classes instead of nesting them?
amc Any help would be appreciated.
amc Thanks

what I do is have a global array of classes and register each class
like this:
class a {
function a(){
global $classes;
$classes['a'] = $this;
}
}
class b {
var $a;
function b(){

Re: [PHP] global variables
In terms of security, or in my opinion, good and proper coding, it is best to have no global variables. There is always a way to wrap variables that will be needed in local scopes. However, this philosophy is harder to practice than it is to preach. Code can get ugly when passing if you are not strong in your coding designing abilities. Sometime it just becomes easier to attempt to keep as much out of the global scope as possible and suffer the idea of some of them being globally available. That being said, if someone was to exploit a script that had global or local access to a variable storing database connection info, then the consequences could be drastic. Similar situations are easly applicable as well, with any crucial data or passwords etc. You should consider reading the section entitled, Security: New Input Mechanism here: http://www.php.net/release_4_1_0.php Regards, Jason k Larson Dara Dowd wrote: Is it better to pass variables through functions or to simply declare them as global within the function's scope?

Re: [PHP] global variables
For this use globals, it would be painfull to pass everything. But you can also use some class that would keep track of such things.

Re: [PHP] Global variables question
At 21:49 10.11.2002, Mathieu Dumoulin said: [snip] Hi, i got this project i'm building right now. It basically a core system to do adminsitrative modules for web sites. I got tons of classes that get created on call of a function like sql_setup(), frm_setup(). These functions create the objects from the classes so they can be used later in other objects...yada yada yada... Now my thing is, instead of always starting my method of an object with global sql_server; and global frm_builder, is there a way that these variables are declared as global automatically, just like i would get $_GET[], $_POST[] and so on, they are already global. I want to do this to simplify development since this project is going to be HUGE. And also it will facilitate debugging as i've been using global at a lot of places and when you forget one, PHP assumes the creation of a dummy variable messing up everything. [snip] Hi Mathieu, to begin with, if this project is HUGE as you said, try to avoid globals as good as you can - they're absolze poison for the readability, stability, and scalability of any application that extends a single source file with a couple of lines. Of course this is only MHO, I'm sure others will chime in here. I am currently working on an application core that's expected to work with a nice number of objects, and it is not feasible here to have objects a) global and simply not possible to have every part of the application using its own reference to the object instance. What I did is to create a container for objects and wrap it into a class I call CCache. As soon as an object gets instantiated it registers itself with the cache (being uniquely identified by Type and ID). Any part of the application simply calls the systemwide cache object with type and ID to retrieve a reference to the specific object it needs just now. I did a performance profiling on this system, and retrieving an object reference from the cache needs approx. 0.001 msec. Just to tell you, not even the cache object is global - there is a public wrapper function around it to return a reference to the global cache object. Currently we have approx. 85,000 lines of code, and absolutely no global variable of our own... -- O Ernest E.

I have just a couple of *handlers* that use classes and I have one class which creates my global array which is shared. It's very easy to trace variables. I'd be very careful before I began to make variables global without some EASYmeans of tracing them. And it gets real interesting when one file inherits another which inherits another and in any one of them the value of your global variable can be changed.

I have a function and was trying to use $PHP_SELF inside of it.
I get a variable undefined error.
Out side of the function it works fine.
I don't want to parameter pass the global variables to the function, I
know
this would work, but I would have to many variables to pass.
This is why superglobals were invented.
Use $_SERVER['PHP_SELF']

I'm not sure about at a htaccess level, but at a php.ini level I believe you can set a file to always include at the top of every php page. This file could simply be: ? $var1 = foo; $var2 = bah; ? Not sure on the specifics, but it was discussed on the list in the last two weeks, and i'm sure there is documentation for the php.ini file IN the the php.ini file, and on the website.

Re: [PHP] Global Variables -- why not have them?
I dislike the GLOBAL statement in that many of the bugs that get me scratching my head are to do with when I have forgotten to use it. Then you're probably using it way too often. Global scope variable are inherently dangerous and cause more problems than they're worth. I've been in this business well nigh 30 years now and have had more problems with globals than I can shake a stick at. Passing parameters ain't a bad thing, you know, even when what you're passing is a variable declared in global scope (like variables set via post or get). Global is inelegant by definition ... I worked in Fortran 77 for 10 of those years; we were really careful with common blocks and included them only where absolutely necessary. Passing array blocks was in almost all cases a better thing and was not any slower.

php does have constants which are _always_ global.

then you refer to it like

You're making an extra step. The variables stored in the $GLOBALS array
don't have to be declared as global within a function. They're already
available within the function. To make a global variable available within
a function's local namespace, you _either_:
* pass it by reference: function cp($userPassword)
* declare it as a global: global $userPassword
* make it an element of the $GLOBALS array: $GLOBALS['userPassword']
(You could also pass by value, but then you're dealing with a copy of the
variable instead of the variable itself.)
