Using IE 6 (XP) i can't see the source generated for PHP even the page works properly (It doesn't happend with Mozilla or Opera).

If i comment out the line:

Any idea what's going on?

Hi hecchan,
I don't have a crear idea on what your problem is, but i have read
an article on phpfreak.com, it says to work the sessioned PHP scripts
correctly with IE6 you have to insert..

         header("Cache-control: private");

                immediatly after starting the session.

try this.

Viraj

p.s.
and also if there is any one wo knows what exactly this header line
means,
please post a brief decription. thanks.

private means that only the intended person that is getting this
file is able to cache it.  So if you're going through a proxy that
proxy must not cache that file.

What is your session.cache_limiter ini setting?

private, nocache, public?

The "View source" in IE 5 and 6 is buggy : it doesnt work as soon as
"there are too many files in the Temp Internetfiles folder". sic.
Solution is of course emptying IE cache... or switching to mozilla ;-)

--- Begin Message --- More safely maybe, but even that solution could be exploited somewhat easily. The script that writes the file would be better off as a CGI than executed through the Apache module, this would allow you to restrict write access to the directory where the file that triggers the restart is stored to the owner of the script, you could then further restrict access to this script through .htccess or other means. If you make a file trigger a cronned job to restart the server if you are using mod_php the directory must be writable to the user the web server runs as which means that anyone who can execute php code through the webserver can trigger a server restart by writing the file, you could even cron it to write the file every minute effectively shutting the server down (whether it be web or the actual system itself).

Doing something like this takes a lot of thought, it can be made difficult to exploit but you need to do more than just make a cron pickup a file, excellent starting place though.

The PHP manual has a section on alterting PHP's configuration with the .htaccess file.

Indenting code and code syntax highlighting make it very easy to spot an open brace, vim is an excellent editor, komodo, zend studio, eclipse, etc.

Cuz the the way the PHP parser is written makes it impossible to discover

are no more braces to go around.

It definitely sucks... almost as badly as a stray backtick. Try finding
that little bugger at 1600x1280...

This is where the benefits of a syntax-coloring text editor really come
into play - you find the missing backtick as soon as you see your code
colored like a text string.

I am trying to see how many times a person has tried to log in during a
session.

the login script...

   $objAuth->start();

   if ($objAuth->getAuth())   // is user logged in already
      ...display hello page...
   else
      ...display login page

OK, so far so good.

If the user punches in anything wrong, the login gets displayed again.

Now I want to track this iteration of attempts.

In the START method, I did this...

    $this->_loginAttempts = $this->_loginAttempts + 1;

then I added

    echo $objAuth->getLoginAttempts();

before ...display login page... to see how it tracks.

It always displays '1'

To me, it looks like '$objAuth->start();' , which is called each time the
page runs, which is each time a login attempt is made, is re-initializing
all the class vars to their default state.

If I make _loginAttempts = 8, then it displays 9.

So, my question (this time) is how do I get the class to track this counter?

I hope I explained this well enough.

I really don't think this is a PEAR::Auth specific question. I think it's
just a "how do I keep this counter going in a class" question.

Thanks

Walter

--- End Message ---

--- Begin Message --- hi,

This is because the life time of an object is only as long as the page. Two solutions: store the login attempt count in the cookies. If you want persistent objects serialize them and save them to disk or db. and deserialize them again on the next page. This will have to be coupled with a uinique identifier (usually associated with a session) so that you know which object belongs to which user.

Pass the value $this->_loginAttempts to the same page, assign it to
$this->_loginAttempts and then increment it.

I have a parent Class that does this in one of it's methods...


        $session = &Auth::_importGlobalVariable("session");
        $session[$this->_sessionName]['registered'] = true;

I would like to "hook" into this in on eof my methods in a child class

I thought I could do this...

[538]   $session = Auth::_importGlobalVariable("session");
[539]   $session[Auth::_sessionName]['registered'] = true;

But I get this error:

    Parse error: parse error, unexpected ']', expecting '(' in
    mypath\AuthUser.php on line 539

OK, I guessed wrong (again).

This is how PEAR::Auth deals with inserting its class vars into a session
and I want to piggyback on that. No need to roll my own, I think.

Can someone show me the errors of my ways?

Thanks

Walter

It looks like you're trying to access a variable of a class, not an instance 
of that class. try something more like

$authObj = new Auth;
$session = &Auth::_importGlobalVariable("session");
$session[$authObj->_sessionName]['registered'] = true;

I'm pretty sure php4 doesn't allow access to variables with the :: operator. I 
sincerely doubt php5 does (although i suppose logically it could be used to 
access static variables...?)

Does your class extend Auth? if so you should use $this-> instead of 
instantiating a new object... I'm honestly not sure what you're trying to do 
here... Even if your class extends Auth, i don't see how changing $session 
would do you any good since it appears to be applicable only to whatever 
function you took that snippet from, not the entire object (which would look 
like $this->session instead of $session)

If you post a more thorough description of what you're trying to do, and 
explain the OOP relationships a bit more, that would help....

I have a directory jammed-packed with images.
I want to read the directory contents /www/usr/htm/images/
and display randomly any *.gif or *.jpg in said directory.
Do-able? Seriously? Ideas? Places to start?

this is in fact pretty easy.
this should get you started

[code]
$files = split("\n",`ls *gif`);
srand((double)microtime()*1000000);
$num = rand(0, count($files));
echo "$num = $files[$num]";
[/code]

this is the way I do if helps

//FILES IN DIR TO ARRAY
$imgdir = "user/home/";
$lista_imgs = array();
$handle = opendir($imgdir);
while ($file = readdir($handle)) {if ($file != "." && $file != "..")
{array_push ($lista_imgs, $file);}}
closedir($handle);

// RANDOM IMG
$rdnum = rand(0, count($lista_imgs) - 1);
$img_home = $lista_imgs[$rdnum];

I assume there are only GIF or JPG files in the directory

As it turned out, all I had to do was get rid of the period "." and things began to 
work better.
I also had to remember to close my browser and empty the cookie jar.
Thanks,

This is not a PHP question but didn't know where else to ask it.  I am
uploading files via SSH Secure File Transfer and am getting the following
error message.

--error message start--
Failed to scan directories. Error 6: C:/Documents and Settings/My
Documents/My Webs/dynamic/1.php: No such file or directory..
DONE - 0 Files  0 Total
Encountered 1 errors.
--error message stop--

Does anyone know why I am getting this message.  It only happens when I am
trying to add a file to a directory.  Any advice or help is appreciated.

Google for "Failed to scan directories. Error 6" (including quotes). First 
result is the ssh.com faq, which has a link to 
http://www.ssh.com/support/faq/secureshell/qa_1_1198.html, which is your 
answer

Hi all,

Not a real bug, but a suggestion:
It would be nice if inifite recursive calls would somehow give an error.
I spend quite some time to find the error in my php script.

I normally program in clarion (www.softvelocity.com) and an infinite
recursive call will cause a heap overflow...

As I only got a "This page cannot be displayed" page, an error must have
occurred, but it's not displayed...
At first I thought I had lost contact with the site, but then, after a lot
of tracing, I found the source of the error.

A computer cannot decide when a recursion is to deep. Imagine traversing
a realy big tree. There a recursion can get realy deep.

I don't know about the internals of php. But as it is an interpreter
language, I would say that all variables or even the parsing tree are
located on the heap. So this heap will probably be quite big! Thus, to
produce a heap overflow will take a rather long time. (Correct me if I
am wrong with my tought)

A workaround could be that you have a counter (static variable!) in your
recursion procedure or methode respectively. You increment this counter
on every entry into the procedure and compare it to a limit that _you_
specifiy.

I was just testing PHP with this code:
<?php

function blah($varible) {

    if ($varible > 860)
        exit();

    echo $varible . '<br>';
    flush();

    blah($varible + 1);
}

blah(1);

?>

This would show 1 to 860, however if I tried any number greater than 860, ie
861 then the page would give the "This page cannot be displayed" page like
you were saying.

Normally apps in C, etc would throw a stack overflow error when you recursed
too high...

I'm guessing PHP doesn't implement this as a normal stack, and is crashing
out because we have hit the memory limit. The reason I say that is because
860 seems a very odd number to set the stack size to.

I'm also guessing that it wouldn't be too hard for the PHP Dev team to place
a limit on the recursion depth, or maybe it is a bit too hard and thats why
they didn't bother :)...

include and friends only load a complete file. You might try fopen/fread 
and count the number of lines loaded.

I know this question is best for the mySQL mailing list, but I am unable
to subscribe to their list at this moment so perhaps somebody here can
help me out.

I have a table with a field where amenities are listed together using a
comma delimiter like: pool,spa,fitness-center

To search this table I use a query that looks something like this:

SELECT * FROM properties WHERE amenities LIKE '%pool%' AND amenities
LIKE '%spa%' AND amenities LIKE '%fitness-center%'

This works, however let's say the user chooses to search for more
amenities. This means the query would need multiple 'AND amenities LIKE
'%____%' statements.

Is there a better way to write this?

I tried the following, but it did not work:

AND amenities LIKE ('%pool%','%spa%','%fitness-center%')

Any suggestions?

Hi all

Based on descriptions in /urlhowto.php  -- Get it on your site,
I tried to redirect GET/POST data to a third page, say,

aaa.php ---> error.php ---> bbb.php
====
aaa.php:
    <form action="unknown.php" method="GET">
    ....
====
error.php:
    <?
    $QSTRING = $_SERVER['REDIRECT_QUERY_STRING'] ;
    ....
    Header("Location: bbb.php?" . $QSTRING) ;
    ?>
====
Everything goes right with GET method, but POST goes wrong in error.php:

The $HTTP_RAW_POST_DATA is lost.
The error.php page could not get the posted data.

Any idea ?

Regards,
CCJ
