Re: [PHP] $GLOBALS example script on php.net
I am unable to provide a better definition that "user defined variables".
User defined variables are variables that are declared by the user. User
here means the creator (or maintainer of the script).
So for:
After...");
print_r($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
Unsetting doesn't leave user defined variables. Unsetting simply destroys variables (or removes elements from an array, etc). There is nothing magic or hidden in that script. I think the note meant exactly what it said: after creating a local copy of the $GLOBALS array and removing super globals from it, all that's left in it are user defined variables. And that's exactly what gets returned from the function.

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 ?

Re: [PHP] $GLOBALS example script on php.net
Dear Ashley, I do follow the part when it creates a local copy of $GLOBALS. When it unsets them, is there a subtlety of unset that it ONLY unsets system defined entries? Could you please explain this ? Thank you, Ashim

against my better judgment, I believe this is what you are looking for.
# Get your starting string
$pieces = "47406|Detroit";
# Break it into the parts you are looking to use
$parts = explode("|", $pieces);
# Empty temporary array

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.

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);

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

]));
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.

Re: [PHP] globals on globals off (help
You can enable them on a per directory bases with .htaccess, take a look at http://www.php.net/manual/en/configuration.php. I recommend using the .htaccess method rather than globally turning on register globals.

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...!! ;)

Re: [PHP] Globals
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.

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.

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

RE: [PHP] $GLOBALS ???
Is this true? :
Session variables are tracked whether or not a visitor's browser supports
cookies. The session id is automatically appeneded to each url on the site
if the user's browser doesn't support 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. What I mean by that is, let's say
I use the "header("Location: test.php?SID&data=Yes!");". I now know that I
would have to use the data in the URL. But for SID, this will apply but I
want to know is, is there any PHP code that will do this behind the scene
without needing to use the URL. $_COOKIE can do this but I can't use
$_COOKIE because if the user's browser had the cookie disabled, then it
wouldn't do me any good.

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 bug??
Are you using any opcode cache? Are you sure it is another process or might it be another thread.

Re: [PHP] Globals bug??
I don't see how. But if what you are saying is actually happening, then it is a Linux kernel-level bug if memory is leaking from one process to another. No matter how badly we screwed up in PHP, the kernel prevents such a screwup from infecting a separate process. I'd suggest having a close look at your code. -Rasmus On 30 Jun 2002 [EMAIL PROTECTED] wrote: > We are seeing a rare bug that seems to imply that there is a bug in PHP's > global variables across httpd processes.

If you refer to a POST or GET (or COOKIE or SESSION or SERVER) variable as $_POST['variablename'] or $_GET['variablename'], then it will automatically be global.

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)
WARNING: I have not tried the code above. Use at your own risk. But the
concepts are there.

Subject: [PHP] globals in functions
Is there a quick way to set all variables as global so that they are
avalible to a function, i'm doing an eval inside, so i need all the
submitted variables to be avalible, or do i have to decalre them
individualy.

If you use a form with method="GET" and submit it all the field names and values are stored in a global associative array called HTTP_GET_VARS as name/value pairs.

As far as I can see, the global version of $test and $HTTP_SESSION_VARS["test"] still reference different memory locations, and they are not the same variable, *while on the current page*. However, if register_globals is "on", then the global version gets saved to the session file, and will be in the $HTTP_SESSION_VARS array on the next page.

Re: [PHP] globals broke
well thats a strange one isn't it. I would double check your php.ini make
sure it wasn't changed, also check the phpinfo() output to see if its
accually using the right php.ini file
http://php.net/manual/function.phpinfo.php
can you use the GLOBALS array?
echo $GLOBALS['foo'];
I dont quite know what to say more, thats a strange one you got there :)
