OK, this works now.

But can I read a whome /etc/passwd into an 3d array ?
This would avoid multiple reads...

I know, that I can have a file as array with file() but
whats the best solution to put it into 3D style ?

I need only to extract the $USER, $GEKO and $HOMEDIR for
UID >= 1000.

Greetings
Michelle

Hi folks,

It is permited to do something like this in the functions "body"

<?
function test()
{
    print("tralala");
    do_some_stuff();
?>

<?
print("test function continue here or not?");
waiting_answer();
print("thanks a lot");
}
?>

Thanks a lot,

You were right! That was exactly the problem
after reading your message, I 've verified the value for gc_maxlifetime
and found that it was set to 1440 secs in other words 24 minutes.

Thank you for that.

But, now I need to come up with something to avoid this behaviour.

The problem is that there's a second php application ruuning on the same
server and I don't want to change the default for gc_maxlilfetime,

So I was thinking on implementing some sort of automatic session refresh
after a short period, let's say every 20 minutes of inactivity.

And of course I should provide the users with a manual way to make
session end, sort of a logout from the application.( no problem with
that)

My question is:

         Is there a way to set sort of a timer as to invoke an hipothetical
"refresh_session.php" without reloading the current page on the client?

Thanks
 Mauricio.

Why not just change it on your pages? The manual says it can get changed anywhere... so just make a call to ini_set() on your pages and other scripts will remain unaffected.

I understand that this setting should make sessions last for at least

3

hours but in my case it seems not to be true since the real duration
varies from 20 minutes to an hour

I think the parameter you need to look at in php.ini is
session.gc_maxlifetime. It sets the session lifetime, not
session_cache_expire. The default lifetime is probably 1440 seconds,
roughly 20 minutes, so the behavior you are seeing is completely normal -
it's all working as it should.

How can I get Polish , iso-8859-2, text,  to output properly ?
PHP is reading the accent characters as blocks

I tried this, but it did not work...

// Set up text for a 'Polish' button
$text = "rozwiązania";
$text = mb_convert_encoding($text, "iso-8859-2","Auto");

//  Composit the text over a button image and output it
imagettftext($im, $fontSize, 0, 11, 16, $white, $font, $text);


is there a simple function that does this ?

many thanks in advance :)

Now, I think it is a text editor problem......

My text editor, BBedit, is set to utf8 encoding .
When I set encoding to utf-8, php outputs a blank screen...






If I use a  Simple/Free Text editor:

everything renders properly....no problems at all

anyone know what this could be ?

Hi,




Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

The output of /usr/local/apache2/bin/apxs follows:
Usage: apxs -g [-S <var>=<val>] -n <modname>
      apxs -q [-S <var>=<val>] <query> ...
      apxs -c [-S <var>=<val>] [-o <dsofile>] [-D <name>[=<value>]]

I'm trying to build PHP 4.3.0 as a DSO for Apache 2.0.54, and I get the following error running configure: checking for Apache 2.0 module support via DSO through APXS... The configure option is --with-apxs2=/usr/local/apache2/bin/apxs. The file does exist and the path to perl is correct and apache was explicitly build with --enable-so (and when I invoke apache with the -l option to list the built-in modules, mod.so.c shows up). So, having satisfied myself that reasons 1 thru 3 don't apply, any idea what else might be causing this problem?

I have recently been working on a site which allows the user to upload a file to the site. Originally calling the $_FILES['file']['tmp_name'] worked fine, however the web host has now disabled all global variables and if I'm not mistaken $_FILES is global. Does anyone know of a work around for this?

Then, it shouldn't matter from which time zone the user is browsing.

hi there I have run into problems with sessions , cookies and expiryt times with different time zones. Ie our server is in the States however I am browsing from Koala land downunder. I have been trying to get the session to expire in a day, however for ppl in the states this is ok, but for me its already expired so i have been experiencing issues. How do i solve this ?

Read what he said again. Instead of expiring the session itself, store the
time of session expiry in the session (with a longer expiry time than 1 day)
and check that.

When you say a day, do you mean 24 hours or a calendar day? Are you trying
to say:

"Today is Tuesday, so expire this session at midnight on Tuesday?"

If that's what you need to do, you need to use a client-side solution -
after all, only the client knows what time it is where the client is! Be
prepared for people who have their time zone set incorrectly.

[2] http://dev.mysql.com/doc/mysql/en/fulltext-boolean.html

Your research group obviously haven't researched very carefully, as "+term" is exactly equal to " AND term", "-term" to " NOT term" and simply "term" to " OR term". So there's no point in complicating the syntax. Not only that, but MySQL's boolean mode fulltext search offers many more great possibilities like truncation ("app*" will match "apple", "application"...) and in-query relevance altering. Take a look at the BOOLEAN MODE section of the MySQL manual [2]; maybe print it and give it to your research group :)

Jasper,

God only knows I have tried. They're old school, what more can I say. If you knew how hard it was to sell them on using PHP-MySQL, when the project was floundering on a MS-Access & ASP server ! They insist on AND, OR & NOT - I have tried. Heck, I have an advanced page with it all spelled out. But it is a good project to hone my owns skills on. So ... a simple str_replace will work. str_replace is case sensitive, if I read the manual correctly? I can get away with: " AND " with "+", " NOT " with "-" and " OR " with " " ? Top-posting? Oh, sorry. I guess I'm old school and stubborn myself. Ok, I'll try working on the bottom of the page.

If all you're really looking for is a static version of your site then you could simply use wget. This will crawl all of the links on your site and generate the static version you wanted.

Hi !

I need some help for mail's encoding structure.
I use this code for encoding french character like 'é' or 'è':

For example :

$res = mail('[EMAIL PROTECTED]', mb_encode_mimeheader($this->subject), $this->msgTxt.$this->msgHTML, $this->entete, '[EMAIL PROTECTED]'); It is working fine unless if my first word is not containing one of those multi-bites characters! Subject : êtes vous francais ou étranger ? => It is well encode and all is fine on differents mail software and webmail Subject : Bonjour, êtes vous francais ? => It is encode at the beginnning of the second word. So it is not well written on some softwre like Incredimail for example. ___________________________________________________________________________ Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!
