Hi,
I use header(location: ...) for redirection to another page. But I also want
to include <title>, <meta> and <link> tags in the other page. Is there a way
to this? Because php complains that the header already been sent.
Regards,
Norman

Headers will be created whenever information is outuputted to the browser.
In this case when you include the .html file into your php script the
browser is going to create all the headers it will ever know for that page.
Obviously this does you no good if you want to add headers later.
Ways around this. You can use output buffering to set headers in non-linear
format. You could use a Javascript to refresh the page after it loads. Or
the way I prefer to do it.. just echo a meta refresh tag between the <head>
tags of your html page. This works with the vast majority of browsers and
you can control the number of seconds before the page redirects.
echo '<head>';
echo '<META HTTP-EQUIV="Refresh" Content="5;
URL=http://www.yourdomain.com";>';
echo '</head>';
Hope this helps,
Kevin

My first post here, sorry if this has been covered before:
Why does including a leading zero in an array index cause
problems? For example, the output of this script:
----------------
$x = array("a","b","c","d","e","f","g","h","i","j");
echo $x[0];
echo $x[1];
echo $x[2];
echo $x[3];
echo $x[4];
echo $x[5];
echo $x[6];
echo $x[7];
echo $x[8];
echo $x[9];
echo "<br>";
echo $x[00];
echo $x[01];
echo $x[02];
echo $x[03];
echo $x[04];
echo $x[05];
echo $x[06];
echo $x[07];
echo $x[08];
echo $x[09];
-----------------
returns this result:
abcdefghij
abcdefghaa
The [08] and [09] values are messed up but [00] thru [07] are
ok.

Oh it's probably because your numbers are being interpreted as octal.
Either use the array as '00' .. '09' or just 0 .. 9. 00 .. 09 is valid for
00 to 07 but there is no such thing as 08 and 09 in octal.

Presumably you've already looked on www.php.net?
You can get the PHP logo and a "Powered by Zend" logo using phpinfo().

Hi!
I have quite an unusual problem for you :) There will be a 24-hour
programming competition at our university, where teams of 3 have one
day to solve a complex problem (which will be revealed on the day
of the competition). Teams cannot get help from "outside", so no outward
network / phone communication is available, but you can use anything you
take there with you (any development tools, books, pre-written software
etc.)
The language in which you write the software is up to you, the most
popular choices being C++ and Java - but this year our team are going
to use PHP (and PHP-GTK).
The big question is: will PHP be enough for the whole project, or will
we need something else (like external C/Java modules)?
Last year the task was to write an artificially intelligent soccer game
based on a client-server architecture: there was a server acting like
some kind of game controller (referee) and 2D display screen, while
the automated clients (players) were playing individually according
to the game's rules and some simulated information on what they 'see'
at the time.
It's said that it will be something quite different this year -
but required knowledge includes:
algorithm theory, information and code theory, artificial intelligence,
queuing, databases, client-server architectures, computer networks,
control theory, 2D graphic programming and software ergonomy.
All this in 24 hours - nice, eh? :)
So the question again - are there any parts of all this where you think
PHP will not be enough? (Apart from the graphics, for which we'll use
PHP-GTK). If so, what kind of outside module integration do you
recommend for us?
Also, which PHP sites / resources / code libraries do you think we should
(recursively) download which might help us a lot? (Apart from php.net,
of course.)
We're really interested in your opinions - is this feasible or
are we just plain mad? :)
Thanks,
Peter Visontay

I've switched "register_globals=off" and "register_argc_argv=off" in php.ini
to use $_SESSION and/or $_POST. All my code had been written using $var
Unfortunately, I cannot seem to access the arrays in either $_SESSION and
$_POST. I've set each page to start with <?php session_start(); ob_start();
?> since I'm also processing the variables from an input html form. Below
that, on my first page the " if (!isset($_SESSION['count'] . . . "
Everything seems to work OK until I try to access, on my last page,
'confirm-guest.php' which attempts to capture either the session variables or
the posted variables from the previous two pages.
Whenever I try:
print("$_SESSION['sfname']); or print("$_POST['scity']
I get a parse error "expecting 'T_STRING' . . ." -- obviously there's nothing
in the array or I haven't set it. Problem is how do you set the "variables",
as in $_POST['sfname'] -- I thought that it would pick them up automatically
from the text input.
Btw, I retained these satements (which could be the problem):
$sfname = $_POST['sfname'];
Since when I tried to use $_POST['sfname'] in the scipt I got the same parse
error as above.
I'm REALLY confused about the whole session thing -- I don't know where else
to read up on it -- I've scoured PHP.net, Zend, PHPBuilder -- and I've
followed what they said, but . . .
Can anyone enlighten me on what I'm doing wrong, or where my thinking is
amiss? I'd greatly appreciate any help.
Tia,
Andre

You just have a simple syntax error.
You can use any of the following:
print $_SESSION['sfname'];
print "{$_SESSION['sfname']}";
print "${_SESSION['sfname']}";
But you can't put a bare array dereference inside a quoted string like you
tried above. You need to surround it with {curly braces} or take it
outside the quoted string.

Hi Miguel,
I tried all three -- none work. I question whether register_globals is truly
"off" since, earlier when I changed php.ini it dumped my Postgresql and left
the phpinfo() unchanged. This time it reported the change, and Postgresql is
working.
Is there a way I can verify that (a) globals are off and (b) $_SESSION or
$_POST are on? This probably what's happening -- I can't access the arrays at
all -- so, I think that might be where the problem lies. The $vars still work
though throughout all scripts.
Any ideas?
Tia,
Andre

I'm running PHP 4.1.2 + Apache 1.3.23 + PostgreSQL 7.2.
I've tried reverting back to globals=on, and same problem. Yet, earlier in
another script I used $sfname = $_GET['sfname']; to get the value of sfname
-- now, it won't work. I'm truly stumped -- I don't know whether it's my
code? [I beginning to think it isn't because of the flakiness of the php.ini
failing to report changes accurately]
I've dumped PHP and re-installed it, but the same problem persists.
Now for the big question -- what's wrong with globals=on anyway? Eventually
the site will be public, and probably the host won't allow globals on, but
what's the security risk?
You say $_SESSION[] and $_POST[] are always on -- even if globals are on?
Can I verify what all the variables in the array are? Where would I look? By
the look of things, I've got a major problem -- but I don't know where to
look.
Help? Please?
Tia,
Andre

Use:
print_r($GLOBALS);
to see what variables you have.

Hi list,
In order to avoid many left joins I took an aproach that I didn't know
if it's good, but I couldn't figure out another way. If my cliente has
10 phone numbers I buld an array, serialize it and store in database, so
I didn't have to create another table. The problem is now I need to
migrate the data to this format, how can I select the multiple data and
put in multidimensional array at runtime to store again. for example I
need to put all fileds with graduation and all fields with discipline
with equal id in array named school serialize it and after insert in
another table.
Thank's
Rodrigo

Just checking:
On success, $UDV->getDbAns() returns array of string;
On fail, it returns false.

Here is your problem - you set $menarr[$h] to
a string, then later try to set stringval[$s][$h] to
a string. Unsurprisingly, PHP has no idea how to
treat a string as a 2d array.

Try echoing this string to make sure it is what you think;
might have to be
... where pa = '{$res[0]}' ";

... the result of explode() is _always_ an array; this
test and the alternate code are unnecessary.
> $maxs=count($subp); // check out how many
> for($n=0; $n < $maxs ; $n++) { // each child in main/sub/n
why not use foreach() ? not much difference, maybe,
just a bit easier to follow...
> // put the value in main/sub/n

as above, $menarr[$h] is a string.

You never set $s to 0; your submenus are going to be
numbered funny, ie
$menarr[0][0]
$menarr[0][1]
$menarr[0][2]
$menarr[1][3]
$menarr[1][4]
etc
> }// end while subs
> }// end if main
>
> $h++; // mainmenues plus one
> }// end while mainmenues
Here is my reorganized code:
$h = 0;
while ( $res = $UDV->getDbAns() ) {
if ( strlen($res[0]) <= 2 )
continue; // skip invalid results ('--' ?)
$menarr[$h]['menu'] = $res[0]; // store menu name
$child_query = "SELECT chi FROM link WHERE pa='{$res[0]}' ";
$UDB->talk2DB($child_query);
$s = 0;
while ( $child = $UDB->getDbAns() ) {
if ( strlen($child[0]) <= 3 ) {
continue;
$subp = explode(" ", $child[0]);
foreach($subp as $key => $val)
$menarr[$h][$s][$key] = $val;
$s++;
}
$h++;
}
Hope this helps.
P.S. ... it seems to me the query-in-query could be
replaced by a single sorted query; the result would
probably be a little faster, but (shrug) save that for later.

I had developed the web-based survey for student.
And I need to check that each only fill in the form once time.
So I write following code to check if the student number
exist in the database or not.
if yes, don't let them to fill in again.
if no, redirect the browser to the page for them to fill in.
=====================
<?php
@ $db = mysql_pconnect("localhost", "survey", "survey");
if (!$db)
{
echo "Error: Could not connect to database.";
exit;

You cannot have anything between the beginning of the file and your <?php

I have $url (literally) embedded in some text in the database that is to be
sent as an email message. I'm using this and $url disappears with a blank
spot in the text:
eval("\$body = \"$body\";");
I've tried variations and can't get it to work. Any help? Thanks.

While you could do something like:
$body = eval("return \"{$body}\";");
...the huge, monstrous, gigantic problem is that if you allow anyone to
edit any part of $body or any string that goes into it, you are basically
handing them control of your server, because they can get eval() to
execute any code they want.
Far better would be to put a placeholder in $body like @@@ and then just
do $body = ereg_replace('@@@', $url, $body);

That's giving me a blank also. The form for changing the email is in a
password protected area where only two people are allowed. But I'll
implement the more secure version when I can get it to work. Thanks
for the help.

If that's giving you a blank then something else is wrong in your code.
This definitely does work:
$body = "Hello, and thank you. Please visit the site @@@.";
$url = "http://boogers.on.toast/";;
$body = ereg_replace('@@@', $url, $body);
Start from the simplest case, verify that it works, and then work out to
include all the other funky stuff you've got going on.

Yeah,I have already restarted web server and there was no error in compiling during
configure/make/install .Using gd,I get the information that concern about GD Support
,GD version,WBMP Support ,etc.as follow:
GD Support -------------------------------------------enabled
GD Version--------------------------------------------1.6.2 or higher
WBMP Support---------------------------------------enabled
the environment variable of LS_COLORS is

By the way,my OS is linux 7.2;kernel is 2.4.17.Before I compiled gd-1.8.4 , I
configure/make/make install libpng-1.2.0&zlib-1.1.4&jpeg-6b without any arguments such
as --prefix and others.Is this right?During the process,there was no error reported.Is
my test code right?

If it was a recompile, try to do a clean installation. Remove the directory
containing your existing php src, untar your tarball, then
configure/make/install.

I have a website where people can signup. Some jerk just made a program
that cheats by signing up automaticly and transfering what he gets when he
starts (you can get virtual money in my game). Does anyone have code to
stop automatic signups? I would write it, but he's about to distribute his
program, which would create quite q mess and unbalance the game. Thanks if
you can help!

To defeat a program you need to come up with something that only a person
can do.
One idea would be to generate a 3-digit number and use GD to display it as
a GIF. Randomly vary the offset and colors so he can't just hash out all
the possibilities. Display the GIF image, and require that the user look
at it and enter that number in order to have their registration processed.
This works because people's brains are very good at pattern recognition
but computers are awful at it.

I apologize in advance, this question most likely doesn't belong here, but
if anyone can help that'd be great:
Using both Perl and PHP to send mail with attachments from forms, the
attachments get truncated. Since both Perl scripts and PHP scripts do this,
I'm ruling out coding error, and since my mailserver has been receiving
e-mails from other sources and has transmitted the whole attachments from
them, I'm ruling it out too. Does anyone know if Apache has some sort of
limitation on attachments? Is there a setting for this in httpd.conf? I
don't have any .htaccess files laying around, just httpd.conf and virtual
hosts. Is there like a max_file_size thing I need to mess with?
Again, I apologize for the off-topic nature of this, just looking for some
help.
Thanks,
Jason

If you're using GET in your form(s) change it to POST.
Also, please do not reply to an existing thread and change the subject. This
messes up the threading for those of us who use an intelligent mail client.

Sorry for the thread thing, I wasn't aware I was causing probs. I usually
just use "Reply" to save having to enter the e-mail address, just laziness.
I'll keep from doing in this in the future, thanks for letting me know.
I'm using 'POST' in my forms - any other ideas or places I could check?
Thanks again.

Hi all,
I got a problem when I using socket function in PHP.
After I use fsockopen() to open socket, I send a msg
using fwrite() and receive a msg using fread(), this work fine. However, I
use fwrite() again to send a msg and use
fread() to receive a response msg, it failed.
The sequence of function call is :
fsockopen -> fwrite -> fread -> fwrite -> fread then fail
Why this happen? any method to solve it?
Thx all your kindly help!!!
Regards,

Spend a bit of time reading up on predefined variables (like $PHP_SELF) in
the manual:
http://www.php.net/manual/fi/reserved.variables.php
I believe you're after SCRIPT_NAME, but it's worth familiarising yourself
with them all for future reference.

Hi,
I stopped searching in Australia and looked over to the US, and am pretty
happy with experthost.com (2GB/50meg/20POP starting at US$15/m)... since
signing up, I changed over to a reseller account to run multiple domains for
clients, and am now paying around US$6.25/m per domain.
I know that additional bandwidth is available too.
The problem is that AU bandwidth is waaaay expensive. A comparable plan to
the above on a reliable, customer service drive ISP in AU is more like
AU$50-150/month, and as you know, getting up near 5gb puts the price through
the roof.
Bandwidth is the US is soooo much cheaper. Unless you have a specificly
focused group of Australian users, and are server a lot of large files, or
stuff that requires really short ping times (like gaming?), I'd recommend
looking overseas... just ensure they have 24/7 support, otherwise you'll
have email/support delays and 3am phone calls :)
