Hi there,
I've only been PHPing for some week and ofcours I've ran into my first two
problems.
1. I'm building this community thing and I have a text file with the users
that is currently logged in. When they press logout there name is deleted
from the textfile, but if they just close there browser or surf to another
site there name is still in the text-file until they log out next time. Any
ideas how to avoid this?
2. How do I sort an array? I've tried array_multisort(); but I can only
"ascci-sort" my array which makes R come before j and so on. How do I sort
alphabeticly and not case sencetive ascci?
Thanks
/Jonas

What you should do is save for each user the last time he was "seen" in
the site: the value of this time is updated for each page he or she
loads. Then, when checking to see if a user is currently logged in, you
check how long ago was he last seen. If it was more than X
seconds/minutes/etc. (this is for you to set), she is considered
"offline" and you can remove him from the file.

Sagie Maoz

Dump the text file and use sessions. Will make your life easier and they provide easy
solutions to problems like "logout".

There are plenty of XXsort() functions in the manual (hint!hint!). Your case needs
natcasesort().
Or you can do it manually with usort() and implement your own comparision function.

I didn't get the third line.. That's no JavaScript..
Isn't this supposed to be something like:
<?
$size = GetImageSize ("images/$resim");
echo "<script language=\"JavaScript\">
echo "document.writeln('width=\"$size\"');";
echo "</script>";
?>

Did you use view source (ALT-V, C) to see what is actually in the "<script

Try something like that:
<?
//$size = GetImageSize ("images/$resim");
$size = 222;
echo "<script language=\"JavaScript\">";
echo "width="; echo $size; echo ";";
echo "</script>";
?>

Thanyou very much guys,
I is working boyan, but your suggestion seems like a long way? he?
--- End Message ---
--- Begin Message ---
Or something easier...
<?
$size = 222;
print <<<HTML
<script language="JavaScript">
width = $size;
</script>
HTML;
?>
Just make sure the "HTML;" bit is all the way on the left margin,
regardless of tabstops in your code.
cheers,
Brad

Hi,
I'm trying to setup an include directory for my site using .htaccess but
I'm having some difficulties.
The command I'm typing is as follows:
php_value include_dir ".:/path/to/my/site/includes"
When I try this, I get an error 500 with Apache. Have I typed something wrong?
Here's my setup:
Apache 1.3.12
PHP 3.0.18
Sun Solaris
Thanks

Hi,
I think you mean hwo u can get the data into an array
well here is an example :
$query = "select .......";
$stmt = ociparse( $connectionhandle, $query );
if( ociexecute( $stmt, OCI_DEFAULT ) ){
ocifetchinto( $stmt, $row, OCI_ASSOC+OCI_RETURN_NULLS );
}
and now you got 1 resultset in an associative array called $row.
take a look at the oci-functions in the manual for the different flags u can
set.

John,
Thanks, the code does actually read this but I'm afraid I removed it so the
servers ip is not exposed to the mail list.
The script runs correctly and opens and creates the page, however it cannot
find the include files I have in the page as the variable
$SITE_DOCUMENT_ROOT requires a session variable.

Hi folks, sorry for the off topic post.
I'm a semi frustrated cobalt xtr user, and I'm thinking about another 1u rack mount
server.
Does anyone have any experience building them? Any good vendors for parts? Any how-to
websites/books? Any other brands you'd recommend?
The cobalts seem to work ok, but I'm running into some real limitations with their
interface and not being able to update php, mysql, etc.
Thanks,
Kelly

Hey guys,
I just got this code (from "PHP BlackBook" pg:213") to make a table in MySql
via a PHP script, I though I knew SQL till I saw this....
CREATE TABLE sh_indexPages (
ID int(11) NOT NULL auto_increment,
Page varchar(255) NOT NULL default '',
PRIMARY KEY (ID)
) TYPE=MyISAM;
What the heck is the "TYPE=MyISAM;" mean?
And to top it all it seems to be running in PHPMyAdmin!
Any ideas?

Okay,
You REALLY need to read the manual(s) before posting. A quick search for
MyISAM on the MySQL site would have told you what you need to know.
a) it's mysql
b) it's easy to find the answer yourself
So don't ask here.

Greetings All,
Thank you for guiding me in the last doubt and special thanks to Juan Pablo
for the link.
Just one question, since I have taken out that MyISAM bit when i made the
table/s, so will it be missing anything?
Com on guys, just on this list I get a load of emails I cant join the MySql
list too, my mailbox will DIEEEE, and anyway this code was in a PHP book....
Cheers,
-Ryan.
--- End Message ---
--- Begin Message ---
No, you should be fine with leaving off the MyISAM. It is the default in 3.23
anyways.

Hey all,
I have a file that is totally filled with PHP functions, its around 15 k.
(func.php)
I have two files (f1.php,f2.php) that each take about 90% and 90% of
differient functions from the first file(func.php),
would my files (f1.php,f2.php) load faster if I defined the functions in
each file instead of including it or is this helping?
Any help appreciated.

It might, but the difference isn't likely to be significant. If speed
is a problem then you need to figure out where your bottle neck is -
unless they are huge files the problem is unlikely to be in loading of
individual file themselves.

If you're running PHP4.2 on a new server (1st install), $FirstName will not
work, because register_globals is probably set to Off in your php.ini file.
Try this:
<HTML>
<HEAD>
<TITLE>Form Results</TITLE>
</HEAD>
<BODY>
<?php
/* This page receives and handles the data generated
by "form.html". */
print "Your first name is {$_POST['FirstName']}.<BR>\n";
print "Your last name is {$_POST['$LastName']}.<BR>\n";
print "Your E-mail Address is {$_POST['$Email']}.<BR>\n";
print "This is what you had to say:<BR>\n
{$_POST['$Comments']}<BR>\n";
?>
</BODY>
</HTML>
You have to get the vars out of the $_POST array, not straight out of the
vars like $FirstName.
It may seem like more work, but since you're new to PHP, now would be the
perfect time to get used to the new method, since it's more secure.
If you find it a little messy though, you could also try:
<?php
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
$Email = $_POST['Email'];
$Comments = $_POST['Comments'];
/* This page receives and handles the data generated
by "form.html". */
print "Your first name is {$FirstName}.<BR>\n";
print "Your last name is {$LastName}.<BR>\n";
print "Your E-mail Address is {$Email}.<BR>\n";
print "This is what you had to say:<BR>\n
{$Comments}<BR>\n";
?>
Which is a little closer to what you had, with 4 lines added to the top. I
wrap $vars within "strings" in {these brackets}, because it makes complex
stuff later on easier & clearer. It's a good habbit to get into.
The above code should work now. If it doesn't, email me and i'll run some
tests on it.

Hey All,
I am just begining to learn regex functions in PHP. Anyhow I am trying
to code a preg_replace function which basically cleans a URL.
What I mean is say a url is index.php?page=hello&list=10&start=4 you
pass that URL and say 'list' to the function (shown below) Anyhow I
want that to then return index.php?page=hello&start=4 (see how the
entire list reference is now gone)
Here is what I have come up with so far, though I am yet to test it as
I am coding this at work :)
function stripUrl($url, $url_strip)
{
// Check that $url_strip is in the URL
if(strpos($url,'?') && strpos($url, $url_strip.'='))
{
// Lets clean up the url
$url = preg_replace("/\?|&$url_strip=/", "", $url);
}
return $url;
}
My problem is that, how do I make the preg_replace stop when it
encounters a & in the URL? If anyone could shed some light on this it
would be appreciated,
- Regards, Scott

this is what I use to get rid of "line" from the url

Hello all:
Not long ago I wrote some php code in my computer which had a apache server,and my
php version is 4.0.5.The code as followed:
$num = 2886732778;
settype($num, integer);
echo $num;
And I found the num is -2147483648.attention,please:the version of php is 4.0.5.
When I installed php-4.2.0 in my computer,however,I found the output of result is
-1408234499.
Why did the difference between the two version php happen?Is this a bug???
Any help is appreciated!

Dunno if it's a bug, but it's 2147483648 to max for an integer? doesn't
bigint support higher numbers than that?
i'm not sure but i think that's why your number gor cut down.

exec wont work if you need to use stdin and read from stdout. You can try

Hi
PHP's sessions are blocking, i.e. until a session is closed, all other calls to
session_start() are pending. If you don't close a session explicitely, it
remains opened until the script is terminated.
The solution is to close a session as soon as possible (session_write_close) or
use non-blocking read-only sessions (session_readonly instead of session_start)
in case you don't need to modify registered variables.

try this:
$query = "select * from news WHERE id = '$_get['id']'";
the double quote right before the $ is ending the string, from that point
on everything is an error.

Another thing you may want to try is the following line:

I am trying to build a login page for client project review site.
I DO NOT want to prompt the user for username and password with header
calls to the browser. I don't want the authenticate dialog box to pop up
on the client browser; I want to collect the username and password on a
PHP or HTML page--I need to collect more data than just username and
password. But when the user submits the login data, I want to set
authentication credentials that work just as though the user entered
data in the pop up. How can I do this with PHP?
Can I set $PHP_AUTH_USER and $PHP_AUTH_PW manually? If so, does this set
the Web server's authentication values for user name and password? If
not, how can I use PHP to set authentication credentials that the Web
server recognizes? Also, if I don't prompt the user with header( )
calls, how do I get the authentication cache on the client browser to
store the auth data?
Any ideas? Please help.
Thanks.

Impossible. HTTP simply does not support you setting these credentials in
the remote browser directly. The best you can do is emulate it using
cookies and/or sessions.

Billy,
There must be a limit to the number of variables you can use in php but I
haven't run up against a limit yet, and php seems to run as fast on my high
variable count code as my more mundane code.
Obviously, the advantage of using variables is that you can group your
"variables/constants" in one area at the top of your code and when you need
to change one of the constants (and you know you will need to do this
eventually) you won't need to look for it in amongst your code.
Not really an answer to your question but more of an observation on my part.
I hope one of the more experienced will also pipe in.
Good Luck
Hugh

Thx Hugh
i got what u mean....let me give u more background for my problem
i am now working on a project which was developed by some others b4.
As the project is a multi-language enabled, there is a PHP file (language
file) which has all the setting , say
--------------------------------------------
$i_no_record_exists_msg = "There is no record at the moment.";
$i_no_search_result_msg = "Sorry, your search yielded no results. Please
revise your search query and try again.";
$i_alert_pleasefillin = "Please fill in the ";
$i_email_to = "To";
$i_status_approve = "Approve";
$i_status_pendinguser = "Pending";
$i_status_publish = "Publish";
$i_status_checkin = "Check In";
.....
..
..
--------------------------------------------
In this language file, over 500 variables are declared. And what i scare is
1. programmatically, should i change all these to CONSTANT? (coz all these
values will never change)
2. if there is difference in declaring variable and constant (say, memory
space required), how much harm it will ?
3. as this file would be included in the entire system....the downside will
be even more....
thx

Hello again all,
I'm using the Mac OS X binary of PHP 4.2.1 provided by Mark Liyanage
(http://www.entropy.ch/software/macosx/php/), and I am starting to notice
some oddities, I was wondering if anyone else had seen these errors in other
ports.
I'm getting some base php functions that seem to be missing, such as:
bindtextdomain
textdomain
And it doesn't seem to like the _() references in array declarations. I
would appreciate any guidance on these...
Thanks,
Wes

Aha. How do i set this from .htaccess anyway?

Hi Miguel,
I can go in for a php based listener, yes, but this system is already in
a production environment and there will be major changes required to get
it done.
If I get a chance to redevelop this, that is probably what I'll go in
for.

So still there is nothing in your requirements that doesn't suggest
you'll
do fine with a PHP-based listener.
Of course you have the memory overhead of the PHP interpreter's RAM
infrastructure multiplied by the number of simultaneous connections, but
that would be the same with Apache (at least on Unix).

Hi
Can anyone please help me with a following problem.
There's a script which uses PEAR library (namely, DB class)
<?
$dbhost=...
$dblogin=...
$dbpassword=...
$dbname=...
require_once("DB.php");
$dsn = "mysql://$dblogin:$dbpassword@$dbhost/$dbname";
$db = DB::connect($dsn, true);
if (DB::isError($db)) die ("*** ".$db->getMessage());
var_dump($db);
?>
When i execute it everything is ok.
BUT when i access this script via redirect by mod_rewrite
it throws an error that open_basedir settings don't allow
this require to be made
.htaccess:
RewriteEngine on
RewriteRule test2.php /~xaxa/test/test3.php [L]
test2.php,test3.php contain the code that i quoted above
error:
Warning: open_basedir restriction in effect. File is in wrong directory
in /home/xaxa/public_html/test/test3.php on line 4
Fatal error: Failed opening required 'DB.php'
(include_path='.:/usr/local/lib/php') in
/home/xaxa/public_html/test/test/test3.php on line 4
Is there any way to overcome this problem?
mod_rewrite is used to _hide_ urls from users and to _extend_ url with
additional params.

I am opening file in append mode but file is not getting created at all. I
am not getting error too. I think it is due to write permission. How to
check it and how to set it ?
Environment - Linux / PHP4
Thanks in advance

Hi all,
I have a Q about functions. My function should return 2 values. What syntax
should I use and how do I call these values outside the function? Are these
values returned as en array or something?
this is what I have now,
-----------------------------
function myFunction($some_vars)
{
$max=count($some_vars);
$some_value=($max/2);
return($some_value && $max);
}
$var1=should be the value of $some_value
$var2=should be the value of $max
thx. Wilbert

Hi,
I don't know if there is an easier way to do this but why don't you concatenate
the two values to be returned and then split the returned value ?
ex :
function myFunction($some_vars)
{
$max=count($some_vars);
$some_value=($max/2);
$result = $some_value.";".$max;
return $result;
}
$resultado = myFunction($some_other_name_vars);
list($var1,$var2) = split(";",$resultado);
I hope it helps.
SR
$var1=should be the value of $some_value
$var2=should be the value of $max

Personally, I'd put both values to be returned into an array and then
return the array.

Hy,
Is it possible to use a javascript variable into php or
to change it into php variable?
I have a list with the files from a directory, this works
fine. For the event onchange I want to show the content of
the file chosen.
So, in the code, the variable "inputf" has the file name
that I want to read. How can I use it in the code php?
Thanks a lot!
Mihaela

Hello
I'm wrapping a newsletter with
$message = wordwrap( $message1,75,"\r\n" );
before sending it out.
still, my customer with his Outlook client gets everything on one line!
(Eudora and Outlook Express on my own machine display it fine.)
Any takes?
Thank you.
