[PHP] Multiple browser instances - is it possible to determine which browser?
We have an application framework that tidies up application session variables as you traverse from page to page. It works really nicely - until a user opens up 2 instances of a browser. Our code cannot distinguish between different browser instances, so browser instance 2 causes our application session vars for browser instance 1 to be cleared out. We've toyed with many ideas and short of forcing a unique hidden value to be 'POST'ed to every page from every page we don't have an elegant solution. Is there any other way that we could do this?

RE: [PHP] Multiple browser instances - is it possible to determine which browser?
We've considered using javascript but cannot think of a way that would work. Take a simple example, 2 browsers - opened separately, pointing at different pages. We thought that we could set some property of each instance of the browser to a unique value (i.e. the window name). We would only need to do it once, when entering the site. But, when a new page is loaded there is no way from PHP to grab this unique value, unless it has been sent to the loaded page as a GET or POST variable. This would mean that we would have to pass this value to every page as a GET or POST variable. GETs are problematic, leaving us with POSTs only. But POSTING to every page is a pain.

RE: [PHP] Multiple browser instances - is it possible to determine which browser
How would that help directly in PHP? PHP cannot interrogate framesets or other attributes of the browser. I could see this working if we had javascript that wanted to keep track of which browser instance is being handled. But from PHP I don't see how this could work. PHP can interrogate the browser to some extent (i.e. to ask for the browser name/version etc..), I guess that what we are looking for is some property of the browser that we can set that PHP can also pickup, or some unique id for a browser instance. -Original Message- From: LuC .

There is no native PHP function for getting a stack trace. This has been discussed many times on the PHP-DEV mailing list. It has always been discarded due to an unacceptable overhead that would be introduced into the parsing process.

(was how to get a function backtrace) hmmm, i spent now a lot of time searching for such a function (discovering many many to me unknown but interesting functions :) - but it seems that there is no such function. And yes: I wanted to use it for debugging stuff. I have a lot of recursive functions and callback functions and it's sometimes incredibly hard to determine when exactly an error happened because I don't know the how maniest instance of a function actually is running and from where it got called. I have made some workarounds, but they are all unsatisfying compared to the possibilities a stacktrace function would offer... Just to give you a little impression what perl has got for such things (and i'd love to see that or something similar in PHP) an extract from the manual: caller EXPR caller Returns the context of the current subroutine call. In scalar context, returns the caller's package name if there is a caller, that is, if we're in a subroutine or eval or require, and the undefined value otherwise. In list context, returns ($package, $filename, $line) = caller; With EXPR, it returns some extra information that the debugger uses to print a stack trace. The value of EXPR indicates how many call frames to go back before the current one. ($package, $filename, $line, $subroutine, $hasargs, $wantarray, $evaltext, $is_require, $hints, $bitmask) = caller($i); Here $subroutine may be (eval) if the frame is not a subroutine call, but an eval. In such a case additional elements $evaltext and $is_require are set: $is_require is true if the frame is created by a require or use statement, $evaltext contains the text of the eval EXPR statement. In particular, for an eval BLOCK statement, $filename is (eval), but $evaltext is undefined. (Note also that each use statement creates a require frame inside an eval EXPR) frame. $hasargs is true if a new instance of @_ was set up for the frame. $hints and $bitmask contain pragmatic hints that the caller was compiled with. The $hints and $bitmask values are subject to change between versions of Perl, and are not meant for external use. Furthermore, when called from within the DB package, caller returns more detailed information: it sets the list variable @DB::args to be the arguments with which the subroutine was invoked. Be aware that the optimizer might have optimized call frames away before caller had a chance to get the information. That means that caller(N) might not return information about the call frame you expect it do, for N 1. In particular, @DB::args might have information from the previous time caller was called. - Original Message - From: Martin Wickman [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, January 14, 2002 10:24 AM Subject: [PHP] Re: How to get a function backtrace?

RE: [PHP] Re: PHP vs. ASP
You should probably consider ASP.NET. Visual Studio .NET is out in early Feb and ASP.NET makes an enormous leap in functionality. It should almost be considered a new web development environment. It allows development in any CLR compliant language (straight VB.NET, C#, managed C++ etc..) It cleanly separates UI and program logic Has better OO implementation than PHP Has easier web design (web forms) Has embedded state managment (run at server tags for form fields) Allows for easily extending and creating .NET complient form controls For me the biggest attraction is the ability to use and mix and match any CLR compliant language. You can now develop a windows client app and as long as you cleanly separate the business layer from the UI layer you can re-use the same business layer in your web apps. Indeed MS are currently working on the Universal Canvas, which 'may' lead to re-usable windows/web UIs. Big downside?

RE: [PHP] Variable definitions...
BTW, the official explanation is wrong. local part this variable is destroyed and declared again is incorrect. The global variable is not destroyed. The local namespace pushes the variable name onto the stack and gives it a value for the duration of the function. Every time you try and access this variable it is taken from the stack by the parser. Once you exit the function the local namespace is destroyed and all the local variables are popped from the stack. If the call stack is in the Global area then all variabels are accessed from the heap, so your original variable (and its original value) are still accessible. -Original Message- From: Chris Hobbs [mailto:[EMAIL PROTECTED]] Sent: 13 November 2001 17:09 To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [PHP] Variable definitions... Hi Stephan, IMHO, I think the answer requested is the only one that really makes sense - as soon as I read it, _my_ first thought went to scope. If a variable changes values, the other value is no longer usable, and thus there aren't really two variables with the same name in that case. When comparing global to local scope, however, you can definitely have the same name in use in two places. Of course, I wasn't a CS major, so someone else might be able to give you an answer that will help you justify yours - but prima facie, you got it wrong :( Now, if you're talking about the compiler level, then no two variables (which are actually memory registers at this point, iirc) can share the same memory space with different values - this is just logically impossible. But the question is certainly referring to source code, and so scope is the only reasonable answer. HTH! Stephan wrote: Hello, first of all I didn't exactely know where the right place is to ask this question. Well, my problem is that I just had some exams and am very unhappy on how certain things were rated. There's especially one question and I try to translate it as exact as possible: When is it possible that two variables have the same name but display different variables? The official solution was when in a script a global variable is declared and then in a local part this variable is destroyed and declared again with the same name (maybe even using different data type). As for me, I'm of the opinion that this definition according to the question is too narrow minded. I think that a variable is already different if the the value within the variable is changed due to script OR if you appoint a new value to the variable OR if the variable is an array and some elements are accessed / elements are added / elements are removed. The reason why I think variables with different values can be considered as different variable according to the question asked in the exam is that when you declare a variable it also has a value even if this value is NULL. Now I'd like very much to hear your opinion on this issue since for me very much depends on that (3 years of studying at college).

RE: [PHP] I need everyones opinon!
Not sure I fully understand you. I'm assuming that you mean that you prefix
each member method with a particular string that relates to the class.
By doing this you lose a key strength of OOP. Namely the ability to write
polymorphic code.
In effect, you would not be able to do the following:
class A
{
function print()
{
print(A);
}
}
class B
{
function print()
{
print(B);
}
}
$arrObjects[1]= new A();
$arrObjects[2]= new B();
foreach ($arrObjects as $key-$value)
{
$value-print();// This is the polymorphic piece - the object
type is
decided at run-time
}
If you methods were called A_print() and B_print() then you would not be
able to build generic code as above.

Hi Guys,
When naming classes and function's within the class(and even
functions(probably more so?)) do you use a common string infront of
everything? For example HM_function_name()
The reason I am asking is because what if you want to easily intergrate a
class/function with lots of other classes/function and then you find out
there is two with the same name?
Any thoughts on this would be good!

If you are setting values in one part of your code and cannot see these

reference problem somewhere. The code you provided looks fine, maybe the
problem is elsewhere.
Alternatively you are looking in th ewrong place. You say that

pets-dog is an array of objects, in which case you should be looking at

RE: [PHP] How is the management of memory by PHP?
Reference counting works in the following way. Normally, if you assign an identifier to the value of an instantiated object then the parser will create a copy of that object. That is, the parser will allocate a physical chunk of memory of the relevant size and copy the memory contents of the original object into this location, your new variable will refer to this new chunk of memory. Say you had something like: 1 $objA = new classA; 2 $objA-temp = 10; 3 4 $objB = $objA Line 4 will cause the allocation of memory and copying of the contents of $objA into this new memory area. $objB will refer to this new copy. Allocating memory and copying values into that memory space consumes resources (time, processor, memory space etc..). Reference counting works by putting of the allocation of memory until such a time as the new copy of the object is actually altered. So, say you have something like: 1 $objA = new classA; 2 $objA-temp = 10; 3 4 $objB = $objA 5 $objB-temp2 =20; At line 4 no new memory is allocated. Instead, both $objA and $objB refer to exactly the same instance of the object. The parser keeps a reference count to this object, in this case at line 4 it will contain a value of 2 (2 variables refering the same object). When an attempt is made to alter the contents of an object the parser checks the reference counter, if it is greater than one then it knows that it needs to create a copy. So, on line 5 the parser allocates some new memory and copies the object, $objB will then refer to this new object. Now, when a property of $objB is altered it does not affect $objA. Once the parser has created a new object for $objB it drops the reference counter for $objA to 1. This is particularly useful for when objects are passed by value to functions. Many functions do not actually change the contents of the object and just use the values inside it. Reference counting improves performance by saving resources involved in the creation of a new copy of an object. Hope this helps.

RE: [PHP] Little question
A good approach to prevent this is to always put your constants on the
lefthand side of the condition. This causes a parser error if you accidently
try and assign instead of compare. It takes a bit of getting used to, but
once you get into the swing of it you'll find it a useful tool in your
arsenal of weapons against accidental bugs.
So, the previous example would read:
if ... == $myOra ... --- This is correct
whereas:
if ... = $myOra ... --- This would cause a parser error, you'd

if ... $myOra == ...
essentially you're setting $myOra as blank everytime which evaluates to
true, then it ends up printing the blank, which is not good. regarding

frustrating! :) you have others but this is the big one.

I have this little snippet of code:
?
$myOra=MY STRING
?
if (!(empty($myOra) || $myOra=)){
?
br
table width=550 border=0 align=center
tr bgcolor=ff
td colspan=3font
size=2bOrario:/b?print($myOra)?/font/td /tr
/table
?
} endif
?
It should print a little table with the string MY STRING...
... unfortunately, it doesn't.
Any suggestion

PHP Version: 4.0.4pl1
MySQL API version: 3.23.22-beta

RE: [PHP] New buzz SOAP?
SOAP stands for Simple Object Access Protocol. It's the XML version of RPC/RMI. It's actually a specification that describes how interfaces from different systems can communicate with each other. It's called an IDL (Interface Definition Language). This is going to be big because it is a very large part of the new Microsoft .NET strategy. In essence it will enable everyone and everything to talk together without worrying about hardware, software or OS's incompatibilities (well, that's the theory, anyway). Of course, I'm sure that MS will make their own non-open extensions and tie everyone into their Worldgrin. The best thing about SOAP is the sense of humour of the designers.

RE: [PHP] New buzz SOAP?
Java rocks. Personally I'm not a fan of MS. However, I saw a sneak preview of .NET in action last July and was astonished by the possible potential for this. There are many aspects of .NET, SOAP being just one of them. I saw code being written in a single GUI development environment where VB called C# called COBOL(??!? I'm serious here). The code was debugged in a single debugger and jumped seamlessly from line to line across different languages. Calling a function/method in a different language was as simple as scrolling through MS's intellisense dropdowns, you don't even need to know what language the relevant function is written in. ASP has been converted to run with the .NET common language runtime(CLR), meaning that you can write ASP in any language compatible with the CLR (i.e. VB, C#, COBOL, umpteen other languages currently being converted). Most cool was the way in which you can create web services. This is where SOAP comes into play. By tagging a function in a CLR compatible language with a 'web service' tag the function becomes exposed and available across the net to anyone else using SOAP development environments (admittedly only .NET at the moment). There were many, many oohs and aahs at the conference, from my position they were well deserved. I'm not a fan of MS but don't write them off. As a developer I haven't such a potential for a revolution since Windows 2.0 first came out. -Original Message- From: David VanHorn [mailto:[EMAIL PROTECTED]] Sent: 03 April 2001 17:59 To: Neil Kimber; Paulson, Joseph V.

RE: [PHP] Passing by reference deprecated?
I'm surprised. I would have thought that it would have been the other way
around. Passing by reference should have similar implications to reference
counting as used the Zend engine. It means that physical memory does not
have to be allocated to passed variables (thereby saving resources in
physical memory and time used in allocating and copying memory).
In fact, because the Zend engine uses reference counting it will in effect
use pass by reference for all parameters. In the case of a parameter passed
as 'non-reference' it will only be allocated its own memory at a time that
the parameter value is changed within the function. You can see a detailed
explanation of how reference counting works here:
http://www.zend.com/zend/art/ref-count.php
I am not familiar with the parser source, so these are purely my thoughts on
my understanding of the parser behaviour. I'd be interested to hear of other
peoples views.

Subject: [PHP] Arrays : Key in Array, True/False
Hi there
I have a script with a function that builds a more comprehensive kind
of array for parsing arguments given a script in PHP (this is a
backup-script I'm currently working on).
My problem is in "THE PARSING OF ARGS PART" when I'm asking the array
if the key exists in the array it returns 0. The key exists, I know
because of the output from the function ( var_dump($array) ), but the
function 'in_array()' only returns true if I ask for a value.
Does anyone know if I can use anything else to give me the possibility
to also ask for the keys, or do I have to write a 'in_array()'-kind of
function myself ??
#! /local/bin/php -q
?PHP // -*- C++ -*-
function parse_arg( $argv, $argc ) {
$array = Array();
for ( $i = 0 ; $i $argc ; $i++ ) {
if ( ereg( "-", $argv[ $i ] ) ) {
if ( ereg( "-", $argv[ $i + 1 ] ) ) {
$array[ "$argv[$i]" ] = "";
} else {
$array[ "$argv[$i]" ] = $argv[ $i + 1 ];
$i = $i + 1;
}
}
}
var_dump ($array);
return $array;
}

while ( list ( $key, $val ) = each ( $arr ) ) {
if ( $key == "-d" ) {

No. You could pass the constant __LINE__ to your function, but I assume that you want this feature to be generically available within all functions. If you really want to be able to track your call-stack then you'd be better off using a development environment like the Zend IDE and debugger. Alternatively you could request a function to the PHP developers mailing list that would return an array containing the current call-stack. You can register your own error handler and assert handler - these guys receive the calling LINE as a parameter. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Milan Mlynarcik Sent: 28 March 2001 14:43 To: [EMAIL PROTECTED] Subject: [PHP] Is there way how to get line number from which function was called ???

RE: [PHP] Creating tree using table?
This is a big topic. I'll be brief. This all depends upon your data structure. There are a couple of ways that you can store information like this. The classic (purist) method would be to have a table of the following type: table_Tree Node ID | Parent ID | Node Data ==+===+== 1 |0 | xxx 2 |1 | xxx 3 |1 | xxx This describes a tree where node 1 is the top (parent id = 0) and has 2 children (nodes 2 and 3). This approach can be used to describe any depth of tree with any number of child nodes. You then need to decide how to represent this in PHP. You could create a node class that contains a collection of child nodes, a reference to the parent node and the node data. You could then construct a physical representation of your tree in PHP. You could then write some routines to traverse your tree and count depth level of any particular node. Alternatively, you could store the data in the db table in the same way in PHP (as an array) and then write some routines to traverse your array. Both approaches are valid and work. You would have to write the code to count the depth of a node. You could also store you information in the database as: table_Tree Node ID | Depth | Node Data ==+===+== 1 |0 | xxx 2 |1 | xxx 3 |1 | xxx 4 |0 | xxx Making the assumption that the rows are ordered correctly. By reading row-by-row you can assume that if a following row is at a lower depth or the same, then you are in the same branch of the tree. As soon as the depth is at a higher level then you have traversed back up a branch. You can store this representation directly in PHP in arrays and then write some routines to render/handle your tree however you like. This approach will give you a depth level directly, however, it's not as 'nice' as the first types of trees as it relies upon order rather than strong relationships with child nodes. Your choice.

RE: [PHP] Editing Variables from another script.
It depends upon what your overall aim actually is.
If you want a different value depending upon where this file is being used
in your site, then you should probably just set the value accordingly in
that part of the site.
i.e.
include "database.inc"
.
.
.
.
$dbhost='localhost';
If you want a different value in the same place based upon a different
'user' or other criteria, then you should probably write some logic to
handle the situation.
i.e.
include "database.inc";
if (MYCRITERIA)
{
$dbhost='localhost';
}
The only reason that I can think of for you wanting to change the physical
file would be if you are writing some code to generate a release for
different users. In which case, you'll probably want to build a parser and
use some kind of templating system.

Okay, basically,
I'm trying to create a script such that it will change the variables
inside
of my .inc page.
Something like
lets say I have this file called "database.inc"
Inside it I have :
$dbhost = 'blah'
$dbuser= 'blah'
$dbpass= 'blah'
I would like to make a script such that I can modify the $variables into
something else like, $dbhost into localhost.
How can it be done?

If you don't want to dump this to the screen but would prefer to have this
in a string (to send to a log file etc..) then use the following function:
function getStringFromObject($prmAryIn)
{
// Following code was ripped from
http://www.php.net/manual/en/function.var-dump.php
// it's very nice indeed!!
ob_start();
var_dump($prmAryIn);

Hi,
does somebody know a function where I can read all variables of an object
independent of there name?
I have to test with large classes, more than 30 vars per class, and dont
want to implement a function just for testing.
I want to echo all values of vars of a class without specifyieng
explicitly
every single varname.
var_dump(PHP3 = 3.0.5, PHP4 )
Dumps information about a variable
void var_dump (mixed expression)
This function returns structured information about an expression that
includes its type and value.
Arrays are explored recursively with values indented to show structure.
Compare var_dump() to print_r().

3 ?php
4 $a = array (1, 2, array ("a", "b", "c"));
5 var_dump ($a);
6 ?

RE: [PHP] Editing Variables from another script.
Gotya. The why not limit your include file to only contain those values that
are important to you. So you get something like:
varsdatabase.inc
$dbhost="x";
$dbuser="y";
$dbpass="z";
Then, in your PHP code you just rewrite this simple file. That way you don't
have to worry about parsing files etc... Just delete the existing
varsdatabase.inc and build a new one from scratch. It's no longer difficult
because it's only 3 lines long.
$dbhost='localhost';

It depends upon what your overall aim actually is.
If you want a different value depending upon where this file is being used
in your site, then you should probably just set the value accordingly in
that part of the site.
i.e.
include "database.inc"
.
.
.
.
$dbhost='localhost';
If you want a different value in the same place based upon a different
'user' or other criteria, then you should probably write some logic to
handle the situation.
i.e.
include "database.inc";
if (MYCRITERIA)
{
$dbhost='localhost';
}
The only reason that I can think of for you wanting to change the physical
file would be if you are writing some code to generate a release for
different users. In which case, you'll probably want to build a parser and
use some kind of templating system.

Do you mean that you want to alter the physical contents of
'database.inc'?
This would require you parsing the existing file yourself, writing a new
version of the file, altering the relevant line of code, removing the
original file and renaming your new file to the original filename.
This isn't a good approach, are you sure there isn't a different way for

Better still - use the set_error_handler() to define an error handler that

RE: [PHP] redefine constants
define() gives you a literal copy of the value of the second parameter. In this case your second parameter is __LINE__. The value of __LINE__ represents the current line number of the define statement. Once defined the value assigned remains constant, irrespective of whether or not __LINE__ changes later on. You could 'redefine' the value - but you'd just get the line number of the redefinition. You really want a reference (pointer) to the __LINE__ constant, however, you can't have references to constants. So, you just plain can't do it. If you think about it, this is a pain only with the parser 'constants', you wouldn't need a reference to your own constants as they never change. -Original Message- From: Christian Dechery [mailto:[EMAIL PROTECTED]] Sent: 28 February 2001 16:13 To: [EMAIL PROTECTED] Subject: [PHP] redefine constants why can't I redefine __LINE__? like define(LN,__LINE__); it's a rather big constant to put in code to generate my error messages, I was thinking more of L, or LN... but if I redefine it, it assumes the value of de redefine() line of code... so it's not really redefining a constant it's only atributing LN the value of __LINE__... and in the manual I saw examples where redefining constants were used... .

RE: [PHP] when using die(), how can i get the line number that errored?
Rather than use die() why not use trigger_error() and have an error_handler
registered with the parser.
Firstly, create an error handler and register it - I use something like the
following:
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
$locStrMessage = $errfile . " " . $errline . " " . $errno . " : " .
$errstr;
error_log($locStrMessage . "\r\n",3,'debug/debug.log');
}
Register this in your autoprepend file using:
set_error_handler("myErrorHandler");
Now, whenever you get an error it gets logged to your debug file with the
file and line number. You can 'generate' errors using trigger_error() and
pass it a string of information. You can use this method to catch absolute
bad bugs and also to dump useful debug information.
This is quiet an elementary implementation of good error handling, you can
take this and extend it into quite a useful system for tracking bugs. You
could add system flags for turning debug on and off, alter levels of
debugging etc...

Neil
