Re: [PHP] $GLOBALS example script on php.net
I am unable to provide a better definition that user defined variables.
User defined variables are variables that are declared by the user. User
here means the creator (or maintainer of the script).
So for:
?php
$a = 'A';
$b = 'B';
$c = 'C';
function globals() {
$globals = $GLOBALS;
print_r(Before...);
print_r($globals);
foreach (array(
'GLOBALS',
'_ENV',
'HTTP_ENV_VARS',
'_POST',
'HTTP_POST_VARS',
'_GET',
'HTTP_GET_VARS',
'_COOKIE',
'HTTP_COOKIE_VARS',
'_SERVER',
'HTTP_SERVER_VARS',
'_FILES',
'HTTP_POST_FILES',
'_REQUEST'
) as $var) {
unset($globals[$var]);
}
print(br /After...);
print_r($globals);
return $globals;
}
globals();
?
You will get: Array( [a] = A [b] = B [c] = C ). $a, $b and $c are user
defined variables.

Re: [PHP] $GLOBALS example script on php.net
It doesn't though, it creates a copy of the $_GLOBALS super global array, removes entries that will have been set by the system (i.e. it leaves user-defined variables) and then returns the ones that are left, so in that, the user note is perfectly correct. What has me puzzled is how unsetting LEAVES user defined variables ? Why would that happen ? The array in the function lists the common server-defined variables (HTTP_VARS, etc), which it unsets from the local copy of the super global array ($globals). Basically, it loops through the un-named array, and unsets that index from $globals. Thank you, Ashim

You are right. The user note is incorrect.

[PHP] Globals or Super Global Variables To Be Reused from For Loops
Hi,
I have a snippet of code as shown in the following:
$message2=47406|Detroit;
$stringChunk2= explode(|, $message2);
if ($message2!=) {
$count_chunk2= count($stringChunk2);
$count_chunk_2= $count_chunk2-1;
}
for ($j=0; $j$count_chunk2; $j++) {
$string3= $stringChunk2[$j];
if ($j $count_chunk_2) {
$string2= OR ;
$string3=$string3.$string2;
}
else {
//Don't do anything
}
echo $string3;
}
The code itself works, but I would like to reuse $string3 variable somewhere
else where I can build SQL statements from it.
I tried using
global $string3;
echo $string3;
after the final curly brace, but I only get Detroit and not 47406 OR Detroit.
Can anyone please suggest me what I should be using here?
Thanks for your help.
Alice

Alice,
The big problem here is that you are resetting the $string3 variable in the
loop
for ($j=0; $j$count_chunk2; $j++) {
$string3= $stringChunk2[$j];// -- resetting
the value
if ($j $count_chunk_2) {
$string2= OR ;
$string3=$string3.$string2;
}
else {
//Don't do anything
}
echo $string3;
}
I am not sure of your goal since you have not stated it, but it certainly
should be easier to just replace the PIPE with the OR
$message = str_replace(|, OR , $message);

RE: [PHP] Globals or Super Global Variables To Be Reused from For Loops
Hi,
Sorry, I cannot use that because I am supposed to turn the string into
something that looks like regions.name LIKE '%47406' OR regions.name LIKE
'%Detroit', which I had to fix $string3 variable to
$string3=regions.name LIKE '% . $stringChunk2[$j] . ';
The goal is that the $message variable would be only a $_POST['message']
variable so that the where clause can be generated dynamically.
The code I have above is part of my where clause in the full SQL statement I
intend to
construct, which means I have to reuse this $string3 variable somewhere
else.
This is what my global declaration looks like:
if ($j $count_chunk_2) {
$string2= OR ;
$string3=$string3.$string2;
global $string3;
}
else {
//Don't do anything
}
echo $string3;
}
echo $string3;
The last $string3 echo only gives me regions.name
LIKE '%Detroit' according to the current construct and not regions.name
LIKE '%47406' OR regions.name LIKE '%Detroit'. Is there something else I should
do to have it give me the same output as the echo $string3 as I have had after
the second to last curly brace?
Thanks again for your help.

[PHP] globals, simpletest and php from command line
I have a php app that runs on php4. I am writing some unit tests now using
SimpleTest but some of the libraries that I have to pull in for testing are
failing. For example, my db library sets some params:
$dname=mydatabase;
$usr=me;
..etc
I then have some mysql functions that connect using
function con(){
global $dname;
..etc.
}
When this is all run from the browser, things are fine but via simpletest
and command line, the globals are lost. Is this just a problem with the
command line or with simpletest?
Thanks.

[PHP] Globals Variable question
Hi All,
Can someone tell me which is better, or if there's a reason I should use one
and not the other (since both seem to work), and if this is the
correct way to access script variables inside functions (and classes):
Example 1
$GLOBALS['db_name']=website;
function QueryDB() {
echo $GLOBALS['var'];
}
QueryDB();
Example 2
$db_name=website;
function QueryDB() {
echo $GLOBALS['var'];
}
QueryDB();
Many thanks

[PHP] $GLOBALS containing itself!!!
Just curious about something I came across.
I was looking at the $GLOBAL array, to see what my script was leaving behind.
$GLOBALS contains a reference to itself.
Even though its a reference, whats the sense with that??

Well .. it basically just Contains a reference to every variable which is
currently available within the global scope of the script. The keys of this
array are the names of the global variables.. Since $GLOBALS itself is
global, that too is contained.
So:
var_dump(isset($GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB

GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]));
Will still print out true. the displaying of *RECURSION* is to prevent, well
.. ehmm, recursively printing out the $GLOBALS array over and over again.
This is something new in PHP 4.0.4. Read the manual on page
http://nl3.php.net/manual/en/function.print-r.php:
Note: Prior to PHP 4.0.4, print_r() will continue forever if given
an array or object that contains a direct or indirect reference to itself.
An example is print_r($GLOBALS) because $GLOBALS is itself a global variable
that contains a reference to itself.

[PHP] Globals set to off - Sessions
I am not sure what I have to do in order to control sessions in PHP
4.33 when globals are set to off.
I used to use the following function to check if the user was of admin
status;
function check_admin_user()
// see if somebody is logged in as admin and notify them if not
{
global $admin_user;
if ( (session_is_registered(admin_user)) (isset($admin_user)) )
return true;
else
return false;
}
Then in my protected pages I would say;
if (check_admin_user())
// if you're an admin user display the following
{
Session_register(admin_user);
// Do admin functions
}
Else
{
//Do login form
}
How do I adapt the check_admin_user() function and the pages to work in
4.33?

[PHP] Globals on/off , PHP.ini and .htaccess - Best solution?
Hi, we have a site that is catering to webhosts and programmers, as you can understand these people know computers and programs :-) They are fooling around with the default settings of their accounts and giving us funny results and basically being a PITA, asking them nicely to quit... we are sure just wont work...so we have decided to turn globals off. We are in the process of doing this to around 250 scripts and now we have run into a problem... (we are on a shared host and so dont have access to our php.ini file) we are planning to turn globals off via a .htaccess file...nearly all our php files are in root (/www/) , but we are also running a third party application 1 directory above root (/www/theApplication/) which requires globals on, when we tried to use a htaccess to turn off globals in the root all sub directories too went off...so we added another .htaccess in the sub and we got errors What to do? how can we have globals off everywhere but in the /www/theApplication/ Cheers, -Ryan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You can enable them on a per directory bases with .htaccess, take a look at http://www.php.net/manual/en/configuration.php.

I'm curious if someone could explain to me why this is occuring:
function blah() {
//global $GLOBALS;
echo 'Globals: pre'; print_r( $GLOBALS ); echo '/pre';
}
As it is shown above, with the 'global $GLOBALS' line commented
out, the print_r() works and shows all the currently
defined variables
and their corresponding values. However, if I declare $GLOBALS
as global, nothing gets printed out.
Why?
Well, I'm kinda guessing here, but it probably goes something like this:
global $GLOBALS;
is the equivalent of doing
$GLOBALS = $GLOBALS['GLOBALS'];
but this causes $GLOBALS to be a local variable within the function, so the
sequence PHP executes probably goes like this:
(1) set up $GLOBALS as a local variable of the function, masking out the
true (super)global $GLOBALS.
(2) look up the 'GLOBALS' element of this new local $GLOBALS -- this is NULL
as no value has yet been assigned to the local $GLOBALS!
(3) create a reference to the NULL obtained from this lookup, and assign
that to the local $GLOBALS.
So what you've ended up in the $GLOBALS which is local to the function is a
reference to NULL, hence the behaviour you're seeing.
Like I say, this is all guesswork -- albeit slightly educated guesswork,
based on my scant and very ancient (over 20 years ago!) experience of
writing bits for a couple of interpreted languages. Maybe a PHP internal
person might come along and tell me how close I got...!! ;)
Cheers!

Why?
Wouldn't the 'global $GLOBALS' line be more or less redundant in
most cases? Because $GLOBALS is a superglobal (though, it isn't
really)? Why would it affect whether or not $GLOBALS actually has
the expected data inside the function?
While I'm on this subject, why isn't $GLOBALS always a superglobal?
For example, this doesn't work:
function innerFunc() {
echo $GLOBALS['blah'];
}
function outerFunc() {
innerFunc();
}
$blah = 'bob';
outerFunc();
Nothing gets echoed from innerFunc(). Why? If anyone can offer
any insight as to what is going on, I'd be ever so appreciative.

Re: [PHP] Globals
I can't speek about the first problem, but about the second one.
You are not setting the variable $blah as a global variable.
Try this instead
$GLOBALS['blah'] = 'bob';
and that should work.
You need to look into scope when refering to variables and functions.

Maybe it has to do with the fact that the $GLOBALS[] array has a copy of
itself inside the parent.
kinda weird but it looks like this
$GLOBALS['key1'] = 'value1';
$GLOBALS['key2'] = 'value2';
$GLOBALS['GLOBALS']['key1'] = 'value1';
$GLOBALS['GLOBALS']['key2'] = 'value2';
don't ask me why, but it seems odd to me to do this. A little redundant if
you ask me.

Assuming line 22 is (it would help if you told us _which_ is line 22)
$smarty-assign(message, $message);
and assuming that you _really_ have defined $smarty in the main code then I
cannot see what you're doing wrong.
Does $smarty-assign(message, $message work in the main loop (ie when not in
a function)?

Are you sure
$smarty = new Smarty

Can it be in another function?
Try setting
global $smarty;
just before you create $smarty.
Does that help?

no, register_globals is only about the automatical production of variables

global $smarty;
just before you create $smarty.
Does that help?
Thanks, that's nice help :)
( register_globals = off )
Imho, globals don't working with globals off, nut i can't find this in
manual.
no, register_globals is only about the automatical production of variables
from FORM, GET and other data input.
But i fully agree the name is confusing.

[PHP] globals not working?
I have an odd problem.
I have a file called evt_to_web.php. This file contains some variable
assignments and a few functions.
I have used
require_once evt_to_web.php;
in another file, indextest.php.
In indextest.php, I then call a function that is in evt_to_web.php.
That function cannot seem to see it's own global variables, even though I
have used global etc;.
I'm pulling my hair out.
Here is evt_to_web.php:
$evthostname = localhost;
$evtusername = paukai;
$evtpassword = imctiger88;
$evtdatabase = imc_evts;
$evtevents_table = evt_events; // Table where all events will be stored.
$evtclient_table = evt_clients; // The owners of events and their login
info
$evtcategory_table = evt_cats; // Small table with categories for event
sorting
// Administration password
$evtadmin_password = imccalendar;
$evtimg_dir = images/;
// Webmaster, in case of error:
$evtwebmaster = [EMAIL PROTECTED];
// Redir site in case of error:
$evtredir_site = http://www.illinimedia.com/;;
function testGlobal() {
global $evtredir_site;
echo TestGlobal: '$evtredir_site'br\n;
}
When I do testGlobal(); I get:
TestGloal: ''
Showing me that the function testGlobal thinks that $everedir_site is empty.
What have I done wrong here??
Thanks,
Paul Kaiser

Hi Paul,
function testGlobal() {
global $evtredir_site;
echo TestGlobal: '$evtredir_site'br\n;
}
When I do testGlobal(); I get:
TestGloal: ''
Change this function to:
function testGlobal() {
global $evtredir_site;
echo TestGlobal: . $evtredir_site. br\n;
}

Is this true? : Session variables are tracked whether or not a visitor's browser supports cookies.

This represents one of the major differences between setting your own cookies and using sessions. -Original Message- Haven't seen this post on PHP newsgroup.

Re: [PHP] Globals bug??
When I said process I meant request. Sorry. Is it possible that the PHP globals are being used across requests (i.e., within the same process)? We noticed this when upgrading from a version of PHP (4.0.6?) prior to the new super-globals being added to PHP 4.1.2. The code in this case is so straightforward that I can't see any other explanation. The variable in question comes from the URL. For example, if the URL is http://foo.com/page.php?var=abc, $var in the PHP is a different value in these rare cases. And the variable we use here is in a very specific format and it is a valid value just that it's a different value from the one in the URL. Also note that we've only seen this problem when the variable has a longer string than the one in the URL. Using the URL from the above example again, $var has a value like abcdef which is valid value but longer (in addition to being wrong). It's as if PHP is re-using memory from a previous request and is not truncating the string properly for the next request. Does that make more sense? Possible?

RE: [PHP] globals in functions
1: Globals are bad...m'kay.
You should never use globals. If your function needs a variable, you should
pass it in. There are exceptions to this rule but it's not a good idea to
program normally this way.
2: Is this a form?
It sounds (from the way you word it) that the variables are part of a form.
If so, pass $_POST into your form and it will be able to evaluate them. If
it's METHOD=GET then use $_GET. This is also a much more generic way to
program since if you add a new variable to the form, you don't have to make
it global in this function.
if (myFunction($_GET)){
echo Everything is hunky dory!;
} else {
echo Blow Chow;
}
function myFunction($formArray=null){
if (isNull($formArray){
return false;
}
if (isarray($formArray)){
return true;
} else {
return false;
}
} // function myFunction($formArray=null)

[PHP] globals not working for me with 4.1.0

Under 4.0.6 I was able to do the following: global $PHP_AUTH_USER,$PHP_AUTH_PW; echo $GLOBALS[REMOTE_ADDR]; This would echo the correct results. Now after the upgrade, the code above does not echo anything. This will work, however: echo $_SERVER[REMOTE_ADDR]; In my php.ini I have the following: register_globals = On register_argc_argv = On Any ideas on how to fix these global variables not being set?

[PHP] $GLOBALS array
Does anyone know if it is possible to use the
'global $varName'
function with the '$GLOBALS' array itself.
I have been having some trouble with this. I have decieded to switch of
register_globals in the php.ini file (seeing as
it is now deprecated in version 4.1.0)
I know that register_globals is still supported, but I would like to get used to not
using it.
But anyway, the problem I am having is that when I post data from a form to another
page the data is not available
globally, so I wrote a method to register them globally, it looks like this
function globaliseVars($varArray) {
global $GLOBALS;
while (list($varName,$var) = each($varArray)) {
$GLOBALS[trim($varName)] = trim($var);
}
}
But doing 'global $GLOBALS' doesn't seem to make it refer to the actual '$GLOBALS'
array, the only time it did work was
when I place something into the '$GLOBALS' array on the page that calls the function.
So
/**
* This doesn't work
*/
globaliseVars($HTTP_POST_VARS);
/**
* But this does
*/
$GLOBALS[ANYTHING] = anything;
globaliseVars($HTTP_POST_VARS);
If anyone could help me with this problem please could they get in touch, because its
driving me crazy.
Thanks!

RE: [PHP] PHP globals aren't really globals
I never used 50 of them, but I think there's such a thing as 'register globals' wchich makes all if the globals become available inside your funcs.. no idea how to use it ...

Is this really the idea of global vars? Well having a form with LOTS of fields, it might be advisable to have the fields send an array straigt away have the name of your fields something like .. name="feedback[name]" .. and just use global $feedback and the whole array is at your disposition. This doens't change the way global is treated in PHP but might help you in your setup. having these in an array will also greatly make sessions easier, if you have to follow all these fields on multiple pages. -- Thierry Coopman - [EMAIL PROTECTED] My opinions are personal, and have really nothing or nothing to do with Keytrade!

RE: [PHP] PHP globals aren't really globals
function u want to use it. THis is not nice, what about if u have a form with 50 fields and want a function to validate all of them, u have to pass them all to the function or build a little piece of code to make all the $GLOBALS local right? Is this really the idea of global vars? Yes. But with regards to form variables, all you need to do is make one variable global: $HTTP_POST_VARS it is an associative array that contains all the post variables from the form. Make it global and just loop through it. Chris

But one thin I can't get, how can PHP call a variabel global, if it isn't global. A global var, is a var defined outside all functions and it's available to all and altered by all, without having to redefine or call the var again. That may be your definition of a global variable. It isn't mine. The fact that you have some way to access the variable from every scope makes it global by my definition. Also, all global variables are available via $GLOBALS['var_name']. And if you really do have 50 global variables, you should really appreciate this feature as your chances of having local/global variable overlaps which can cause weird bugs is that much higher. I would suggest grouping your variables into logical arrays of information and doing a 'global' on these arrays instead. In PHP, for a var to be global you have to add a 'global $var' inside the function u want to use it. THis is not nice, what about if u have a form with 50 fields and want a function to validate all of them, u have to pass them all to the function or build a little piece of code to make all th $GLOBALS local right? If you have a form with 50 fields, name them like this: input type="text" name="blah[abc]" input type="text" name="blah[def]" input type="text" name="blah[ghi]" Then simply make do: global $blah Is this really the idea of global vars? The idea is to avoid really nasty scope-related bugs that are common in C code that uses lots of global variables. Years and years ago when I wrote the first version of PHP I was working for a telco writing software for a large telephone switch. The code was huge and extremely ugly. Global variables everywhere. The team had been chasing a bug for about a week when I got stubborn and decided it was time to kill the bug. I printed out all the source code and laid it out in a long hallway as I crawled along with different coloured pens and manually traced my way through it as none of the debuggers we had at the time were of any use. After countless hours the bug turned out to be inside a function that silently modified a global variable which affected another piece of code in a completely different part of the program. I swore I would not have the same problem in PHP and thus the requirement for people to be explicit about using global variables inside functions. Hopefully it also forces a little bit of structure and organization on people. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

In most languages, heck , all I can think of, the variable's scope is simply dependant on WHERE it was declared, not how it was declared. If in C/C++ you define a variable outside the scope of any function, then it becomes global and can be accessed by any function. I'm not arguing one side or the other, just stating :) I personally find the PHP way a bit annoiying, but its workable, and i'm SURE there was a reason for it.

It seems to me that the several other ways folks have listed to solve this one example indicates that we don't really need the temporary convenience of wide open globals (temporary as in it doesn't end up very convenient when they create problems).

It seems to me that the several other ways folks have listed to solve this one example indicates that we don't really need the temporary convenience of wide open globals (temporary as in it doesn't end up very convenient when they create problems). I was always tought very simply, don't use globals :) However, that isn't always an option. I have no problems with the way PHP does things. I think its a good idea for the shelter. What I find interesting is that it seems when you are first learning a language, you use more globals, than when you are more experienced with it. When I first started programmig in C, 99% of my variables were global. Look at any of my C/C++ code nowadays, over 10 years later, and you will be hard pressed to find a global. PHP is still new to me, so i'm still trying to use alot of globals. Because of the way PHP handles it, i'm jumping through a few hoops. That is annoying, but I don't consider it a problem, because as I get better, I know I will go back through and rewrite things to not use globals. I guess my confusion is this: I am passing all my variables around between scripts by sending them through the URLs (index.php?mode=index). I guess what "annoys" me, is I would expect those to be available from inside the functions, but they aren't. - John Vanderbeck - Admin, GameDesign Visit the Gates Motel webgame: http://www.gameslate.com/gatesmotel/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I never had any problem handling them, but in the other hand I never had 50 of them in a program. I can understand that making global every single form variable would take a whole lot of control by the compiler... I just came with a nice foreach() to make my globals local, and I have to put them in ALL my functions that handles form vars... I'll consider using arrays in my next forms but hey, don't worry...

Re: [PHP] PHP globals aren't really globals
I believe you use globals $var to ACCESS a global variable, not to define. That's correct. To be perfectly correct here, what you are doing is creating a reference to the global variable. Think of it as an alias to the same variable as the global variable. global $foo; would be equivalent to: $foo = $GLOBALS['foo']; With the latter giving you the ability to use a different name for the local reference to the globally-scoped variable. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] PHP globals aren't really globals
It's somewhat annoying to have to tell the function which variables are global sometimes but overall it makes it easier to avoid stupid mistakes. It is a good push to make me less prone to making things global. Usually I just avoid using globals and then pack what I do use into appropiate arrays and thus save myself most the hassle. In several thousand lines of code I may have one or two global vars called. Boget, Chris wrote: Yes.
