Then, what about bookmarks? ...
No, what I had proposed was an alternate method to accomplish what
you said you wanted. But, it appears that my efforts and the demo did
not receive sufficient attention for you to understand what wass
being presented. Instead, you tell me that what I've shown you is bad
practice -- interesting.
You said that you wanted to remove login from the browser history,
which is screwing around with the user's browser and is clearly bad
practice.
My method simply stops the user from visiting the same page more than
once during a session and leaves their browser data alone -- nothing
bad practice about that!
AFTER my demo runs, if you repeatedly refresh the page you are
directed to, then certainly that would become annoying. But that
wasn't the intent, nor part of the demo, which you clearly didn't
read and obviously didn't understand.
As far as bookmarking the page, but of course you can bookmark the
page! Did you even try?
Oh well, so much for trying to help someone understand sessions. As
my mother often said No good deed ever goes unpunished.
If you had simply said, I don't understand, please explain; or asked
a question or two; or said thanks, but no thanks, I'm going to do it
another way, then that would have been fine. But to say that the demo
I prepared for you exhibited bad practice, especially when you are
absolutely friggen clueless as to what it is doing, is a bit too much

O. Wyss:
Instead of messing with the user's browser (not good IMO), why not
use $_SESSION and make it such that if the user selects the log-on
page again, they are redirected to another page? You don't even need
header() to do that.
Here's an example:
http://webbytedd.com/bb/one-time
You will only see that page only once -- unless you find a way to
clear the session.
The process is simply to set a session variable and allow the user to
see the page once. Upon returning, the session variable is checked
and if it is not null, then the user is redirected to another page
like so:
if($visit != null)
{
ob_clean();
include('a.php');
exit(0);
}
Very simple.
Cheers,
tedd

What is happening?
This is because in the second example, you're including the file in a
different scope than the first example. The file included (and so all
variables etc. declared in it) will be added to the scope where the
include is.
This manual page should help you:

Not exactly... you're returning the return value of an include.
Take this:
var.php:
?php
return bar;

foo.php
?php
function include_bar() {
return include bar.php
}
echo include_bar(); // echoes bar
the file will be included in the scope of the class? Because this i cant use
the variables declared in the file ? all declared in the file only can be
access from the method that i use to include the class file.

No this is not a bug. And it also has nothing todo with scoping.
The object client returns NULL. This can only happen if the object is not
instantiated.
I guess the foo.php file is not included at all.

First of all - I didn't ask the initial question ;-). Other than that, I
think our philosophies our basically the same. But when you say that you are
redirecting the user to another page, while you are actually including a php
script - that's not my understanding of redirecting.
You said that you wanted to remove login from the browser history,
which is screwing around with the user's browser and is clearly bad
practice.
Generally yes, removing a page from the browser's history would be
considered bad practice. However, we are not really talking about a page
here. What I understood from the initial question is as follows:
- http://www.site.com/ contains some login form, action of that form is
(for example) /login.php
- The user is sent to /login.php where the login is checked
- From there, the user either gets to a content page where it would
typically show welcome {user} or something, or back to the index page when
login failed
- As you see, login.php is not really a page but more of a 'pseudo page'
and therefore I cannot see any reason not to send a proper 303 header. see:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
My method simply stops the user from visiting the same page more than
once during a session and leaves their browser data alone -- nothing

I don't think there wasn't anybody who didn't appriciate your suggestion.
Only thing I was trying to do was chip in my two cents. Again, I wasn't the
one who originally asked the question and I certainly am not friggen
clueless. I just came to think about what the teacher at my Flex course
from a couple of months ago said about good and bad practice. He said
there is none. If your solution works good for you, that's your good
practice. And if mine doesn't work for you, it's your bad practice - while
it is still my good practice.
Something however I am trying to fight against, if you let me put it like
that - is people approaching scripts as if they are pages. When you are
including a script that is usually called as a page into another script
you should be very aware for any clashes between variables. Another reason
why it may be easier to just put in a Location: header and call your script
as it was originally intended.

[PHP] PHP eval() fatal error
Here's the thing: I'm trying to do some dynamic code compilation within
PHP using eval(). The code I'm trying to compile raises an E_ERROR (Fatal).
Here's a simple example:
?php
$code = ' $returnValue = 12*A+; '; // Clearly incorrect code :-)
$returnValue = 0;
eval($code);
?
Now, I'd like to catch the error made by eval:
// ...
try {
eval($code);
} catch (Exception $ex) {
var_dump($ex);
}
// ...
Problem persists: a fatal error occurs.
Using set_error_handler() and set_exception_handler() is not working
either...
Is there any way to gracefully catch this error?

Fatal errors are exactly that... fatal. You cannot catch them or recover
from them.
Your best option is to shell out another PHP process, capture the output
and parse that for error messages.

Now, I'd like to catch the error made by eval:
// ...
try {
eval($code);
} catch (Exception $ex) {
var_dump($ex);
}
// ...
Problem persists: a fatal error occurs.
Using set_error_handler() and set_exception_handler() is not working
either...
Is there any way to gracefully catch this error?
Regards,
Maarten
If you read the manual (RTFM) at http://www.php.net/eval you'll notice
the following:
If there is a parse error in the evaluated code, eval() returns FALSE
and execution of the following code continues normally. It is not
possible to catch a parse error in eval() using set_error_handler().
Note: In case of a fatal error in the evaluated code, the whole script
exits.
So, no.

[PHP] for/foreach speed
Hi people, could somebody please explain me, what loop construct is faster? The for, while or foreach. I at the moment don't know if there are more. And thanks to the person who is missusing the list here for sending trojan horses everywhere. Since I write to the PHP General list I am receiving round about 5 E-Mails from random domains, from this list, containing a Jpeg image with an embeded trojan horse. Thats really wonderfull. But maybe I should say, that we are using a nice mailscanner, and as well we are only working on linux machines. So better find another way of performing your frauds. If there are people here in the list, who would like to discuss how its possible to fight this kind of fraud. I am very open to that. Get the hacking tools prepared and lets fight back. I am sure the police would love to get an inquiry from a hole bunch of senior developers wanting to see little assholes in jail!

Hello,
Thanks for your faster answer.
I have to say im runing php cli from linux.
And i havent got many idea about php, i only want to run from command line
that script.
I have test with Daniel Brown's script, but dont work.
If you dont specific the password, then you get the html body when run
the script and with your script, still getting the html body which request
the password.
I cant see the code because is encode with Zend, so, i cant give many
details about it or modify it.
But if it run in the browser, i think it have to run in cli, dont you think ?
Thanks.

I haven't bothered testing but I'd wager $5 that the following is the

Depending on bytecode creation though, the following might be just as
fast:
?php

[PHP] php 4.4.7 make install with pear causes zend freeing errors
Is the only valid response to problems with php4 to
upgrade to php5? Or, are there still some people
out there still using php4 and possibly have had
problems with install such as the following?
If php5 is the only answer, I guess we'll just have
to go with what we have and limp along until we can
get everything converted to work on php5.
I sent this to the php-install list. However, with
no response, I knew there would be more eyes looking
at it here. Hopefully, someone can send me a pointer
on how to resolve this issue. It might be the root of
other problems I am having.
Per my previous message, I have recently upgraded from
php 4.4.0, to php 4.4.7. My configure options are as
follows:
-
./configure \
--prefix=/usr/local/php4 \
--with-apxs=/usr/sbin/apxs \
--enable-debug \
--disable-cgi \
--enable-force-cgi-redirect \
--enable-discard-path \
--enable-safe-mode \
--disable-short-tags \
--disable-ipv6 \
--enable-magic-quotes \
--with-openssl \
--with-pcre-regex \
--with-curl \
--with-curlwrappers \
--with-mcrypt \
--enable-session \
--with-mysql=/usr/local \
--with-mysql-sock=/var/www/var/run/mysql/mysql.sock
-
After running configure and make, I run make install.
This is the output of the make install:
-

[PHP] Monitoring system resources used by PHP
I'm looking for a way to monitor the system resources (CPU, memory, Disk I/O, etc) used by the PHP engine on a linux machine. I can't monitor it by the usual means (top, etc), since it runs as part of the apache process(es). Does anyone know if a tool exists from Zend, or a module for Apache, to monitor resource usage for internal subprocesses such as PHP? The machines I need to monitor are a cluster of load-balanced servers running Perl and mod_jk in addition to PHP, so that complicates things a bit. It was suggested to me on a message board to set up a similar test environment with just PHP and some kind of profiling built into all the scripts, but this would kind of defeat the point, since we're wanting to monitor production machines so that in the case they do down for whatever reason, we can see which applications spiked when and why. Sorry for the lengthy question, hope someone can help. Thanks for your time.
[PHP] Best Practices for calling 'setup' classes that extend 'parent' classes?
What is the best practice for correctly targeting 'include' paths
when using Initialization/Setup classes that extend Parent classes?
In my extend_parent_class.php file, I have to provide an incorrect
relative path. Apparently, the path (that does work) is relative to
php file that calls the initialization/setup class
(call_the_extend_parent_class.php). Is there a less confusing way to
correctly target include paths when creating initialization classes?
Should I be using absolute paths instead?
many thanks in advance
extend_parent_class.php:
include_once('./path/to/parent_class.php'); # Works with 'incorrect'
relative path
//include_once('../path/to/parent_class.php'); # Fatal Error with
'correct' relative path
class Initialize_Parent_Class extends Parent_Class {
function Initialize_Parent_Class()
{
$this-Parent_Class();
echo This was successful and does not result in a fatal 'class not
found' error;
}
}
Call the initialization class.
call_the_extend_parent_class.php:
?php
require('./includes/extend_parent_class.php'); # initialize Parent Class
$parent_class = new Initialize_Parent_Class();
// prints 'This was successful and does not result in a fatal 'class
not found' error'
?
File structure:
php
++call_the_extend_parent_class.php
++ includes directory

++ classes directory

[PHP] Declare variables in advance question
I want to declare these variables Game_id and Member_id in advance. Following
the suggestionfrom one of my books can I do something like this:
$expected = array('Game_id', 'Member_id');foreach($expected AS $key) {if (
!empty($_POST[$key])) { ${$key} = $_POST[$key];}else { ${$key}
= NULL;}} case addmember: switch ($_GET['type']) {case
membergame: $sql = INSERT INTO xsm_membergames
(Game_id,Member_id) VALUES
(' . mysql_real_escape_string((int)$_POST[Game_id])) . ',
' . mysql_real_escape_string((int)$_POST[Member_id])) . ');
break; } break;
My concern is did I achieve anything with the code I just added to declare the
variables? Is it actually being passed to this: case addmember:
switch ($_GET['type']) {case membergame: $sql = INSERT INTO
xsm_membergames(Game_id,Member_id)
VALUES(' .
mysql_real_escape_string((int)$_POST[Game_id]) . ',' .
mysql_real_escape_string((int)$_POST[Member_id]) . '); break;
} break;
I did add this and tested it on my server and I didnt recieve any errors. So
how can I be sure its doing what I intended?
