You need to start the session at the beginning of the script, or use
output buffering.
Either:
<?php
session_start();
require("...
...
or
<?php
ob_start();
require("...
...
You're trying to output stuff to the screen (which implicitly sends the
headers) then trying to send more headers by calling session_register()
(which implicitly calls session_start() )

silly me,
testing the query (echo $query;) was actually causing the problem!

Do not echo $query or any output before session_start(); or
session_register("xxx"); (mean headers)
//echo $query
Or may be you can put ob_start(); before first output and put
ob_end_flush(); after last headers
ob_start();
echo $query
.
.
//your code.
.
.
session_register("ses_level");
ob_end_flush();
Hope this helps!

Hi guys,
I have 2 scripts located in a directory and 3 dirs with 3 subdomain.
Something like this.
/scripts
- input.php
- output.php
/user1 -> subdomain user1.mysite.com
/user2 -> subdomain user2.mysite.com
/user3 -> subdomain user3.mysite.com
What can I do to execute the input.php script from any subdomain and get
output.php (response) in the same subdomain?
Do I need to copy the "scripts" directory in each subdomain dir?
many thanks,
Radu

Hi
I am trying to get mail working with my php setup. I have an exchange
server that I want to send mail to but I get the error
Warning: mail() [function.mail]: SMTP server response: 550 5.7.1 Unable to
relay for [EMAIL PROTECTED] in
I have setup SMTP = my server address and sendmail_from to my email address.
What else do I need to do?

It is the email server that is not allowing your computer
(pittsh.com.au) to connect to send email. Ask the administrator of that
computer to allow your computer to relay through it. FYI it is correct
for email servers to only allow needed computers to connect to avoid
being an open relay for spammers.

i have two scripts included into one page, one of them i have been running
for a long time .. i recently made another script and when i include it into
the same page the other script returns this error:
Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result
resource in /home/public_html/file.php on line 59
This is part of the sql query that conflicts with the other, any ideas? it
only happens when this snippet is included in the same page that the other
is included into.
function load() {
mysql_connect($hostname,$username,$password) or die ( "Could not connet to
MySQL" );
mysql_select_db($database) or die ( "Could not connect to database" );
// Delete
$sql = "DELETE FROM $table WHERE time < " . (time()-$duration);
$result = @mysql_query($sql) or die ("Error:" . mysql_error() );
// Insert
$sql = "INSERT INTO $table (time) VALUES (" . time() . ") ";
$result = @mysql_query($sql) or die ("Error:" . mysql_error() );
// Get count
$sql = "SELECT time FROM $table";
$result = @mysql_query($sql) or die ("Error:" . mysql_error() );
return mysql_num_rows ($result);
}
TIA.

Simple question, only related to this forum in that all of us use
libraries that are compressed.
I'm trying to use adodb, and I uploaded it's zipped archive to a linux
box and gunzip won't unzip it. Says 'multiple entries'. Anyone know how
to upload it, short of unzipping in on a windbloze box, then ftping all
files up?

on your linux box, cd to the directory containing the archive, then enter
tar -xzf {archivename}
In most cases (also for adodb) this will create a directory tree containing
the extracted distribution files in the correct layout. The directory name
is usually similar to the archive name (depends on the archive contents of
course, but in case of adodb it's "adodb" and a version number (I believe).

Turns out the adodb guy DOES have a *.tgz file to download. I got it,
(it's missnamed in the extension), and was able to extract it fine.
Thanks for your help!

I always look in the manual when I'm looking for documentation, but
that's just me. Hell, call me crazy, but I'd probably look in the
chapter on the PG functions... but that's just me... and I have no idea
what I'm doing.

Dear Lady/Sir :
I can not find any technical contact in Mohawk's web but this mailling list
in the internet. I am looking for solutions. If this e-mail bothers you, I
appologize.
I found a possible msession problem in V1.21 only, which is based upon
phoenix-R1_2_030117E (PHP 4.3.0, RedHat 7.2). It looks like :
1. The PHP+msession runs slow as the listener threads increased.
The PHP msession_get( ) will take more than 100ms as the listerner
threads
is increased to 30. This slowness will be triggered only from
PHP+msession, and
that is started after a few executions (say, usually after 10 times).
The non-PHP msession-related programs do not trigger this slowness and
works good.
However, this situation and the same PHP+msession_get program
does not re-create the same slowness on PHP 4.3.0+msession 1.0.
2. As soon as the slowness appears, any msession programs
(including ./tools/list ...) slows down too, until the msessiond is
re-booted.
Anybody has the same problem or solutions ?
Best Regards,
Hammer Wang

Yes sorry for not being clear. I am trying to use exec() and system().
I guess I'm trying to see if there is another way to do it, like write to a
file and have acron job run every minute or so, or if there is some way to
make it seem like I am doing this with the right permissions.

You probably are logged into the command prompt as a different user than
what the PHP binary runs as. If the PHP binary runs as a user named
"apache", and you log in as "dmcullough" or "root", and the commands you
are trying to execute are restricted only to being run by "dmcullough" or a
group that "dmcullough" is in but "apache" is not, then PHP won't run them.
I'm assuming that you are using the system() or exec() commands, your email
is a little difficult to understand in that respect... sorry.

I think it is an amazing feat to have a scripting language with such a
comprehensive (with user notes) documentation, helpful community of users
and developers, and a team of writers who for little reward, continue to
develop PHP to make it work better and faster for us all to use.
So here's to PHP!
Keep up the good work.

Hi,
I am having a problem with one of my session variables, no matter what I
try I can't get a second one to register. My webpage calls this script
directly and I am using the webpage form variables for the variables in
this script. I can register the Name variable but not the LoginName
variable.
What am I doing wrong??
Here is complete script:
<?
require_once ( "DBFunctions.php" );
#Make DB Connection
$result = makeconnection();
if( $result )
{
#validate the user
$Name = validuser("$LoginName", "$PWord");
if( strlen($Name) > 0 )
{
#start a session and register the user and limit the session
to one hour
#session_cache_expire(60);
session_start();
#here is where I check for registered sessions and
registered users
if(! session_is_registered("Name")) // this works as expected
{
session_register("Name");
}
if(! session_is_registered("LoginName"))
{
session_register( "LoginName" ); // this does not work.
}
header("Location:
http://www.xxxxxxxxxx.com/xxxxxxx/xxxxxxxx.php";);
}
else
{
header("Location: http://www.xxxxxxxx.com/xxxxxxxx/";);
exit();
}
}

session_destroy();

Hello,
I am looking for a way to search a file knowing the beginig of his name.
For exemple, I know that the file I am looking for is:
montreal_000013_120.jpg
But I just know:
montreal_000013
And I can't know _120.jpg
So at this time I did this:
$dirthumbs = $dir."/thumbs" ;
$direc_src_obj2 = dir($dirthumbs) ;
while($entry=$direc_src_obj2->read()) {
if( substr($entry, 0, 15) == "$begining"){
$return[$i]["thumb"] = "$entry" ;
break ;
}
}
It works but it's not enough fast :-(
For resume, is there a way to do something like that:
ls montreal_000013*
without using the passthru function, I am looking for a native php
function doing ls $mychar*
Thanks,
Vincent.

I have a class that reads gif images & can then make jpeg or png thumbnails
of the gif image, but it only seems to work on linux. Is there any way to
open/convert the gif to some other graphic format so I can at least read the
gif image in on windows?
here's the current code I have for reading in file types, but the gif
section blows up. Is there a way with something like readfile() or fopen()
to get the information from a gif file?
switch($type)
{
case "gif":
$orig_img = imagecreatefromgif($filename);
break;
case "jpg":
$orig_img = imagecreatefromjpeg($filename);
break;
case "png":
$orig_img = imagecreatefrompng($filename);

I've discovered that it is not the pointer in the array that I am having
problems with but rather the pointer in the result handle.
From what I gather, when a mysql_fetch function (mysql_fetch_row,
mysql_fetch_assoc, mysql_fetch_array) retrieves a row from the result
handle (In this case it is $rsCommunitiesServed), the result handle's
internal pointer is advanced one position.
The first mysql_fetch function (mysql_fetch_assoc) used in the recordset
block causes the result handle's internal pointer to advance to the
second record. So, when I later use mysql_fetch_array, the result
handle's internal pointer is now on the second row of the results and so
it gives me the second record. Actually, I use the mysql_fetch_array
function in a while loop so what I get is all the records in the array
which includes all records from the result set except for the first record.
So, what I need to do is move the internal pointer of the result handle
back to the first row of the result set. How can I do this?
Thank you,
Blaine

I resolved the problem by using the mysql_data_seek function to set the

Just a quick reiteration of something I found that probably most people
already know.. but since I went through the painstaking trouble of
removing the PHP and Apache RPMs and building them from scratch (I hate
building sources), I wanted to make sure this is out there.
If you're having problems getting any PHP code to parse and you ususally
use <? and ?> ...
In the /etc/php.ini file change the short_open_tag variable to On
That's all there is to it.. lol
Also, you might wanna find the extention=mysql.so and uncomment that,
since it's commented by default
Credit goes out to the people who have previously posted this, but it's
been a while since it's been said recently, I just thought I'd help out.

The second part of the error says you need to give the full path to your apxs
executable. If you don't know where it is, use:
find / -name apxs
to find it.

It's seeing the - as a range identifier, escape it to get the literal hyphen.
How about this:
[a-zA-Z0-9_\-.]*
In my tests, the period didn't need to be escaped with the \.

The period is a regex placeholder for "any character". Thus it will match a
period, but also a #, a @, and everything that's not allowed in the planned
regex.
By escaping the period you're changing the meaning from "any character" to
"or a period" (in this context) so I believe that's what you want to do.

Guys I really need your help. How do I restrict users from changing data in
a textarea? I need to display data on a page so that users can edit it and
update the database. With the help of this mailing list I got it going but
now I am running into walls. Some of the data is sensitive and can't be
changed. But the only way I know how to display data
so that it can't be edited directly is in a normal table format or print.
After the specific data has been placed in table format and the rest in
textareas only those in textareas are being used in the mysql query, where I
actually need everything to be used. I have tried declaring global variables
for the variables displayed in table format but this is not working.
I have tried looking for solutions on the net and the php manual but can't
find anything. I know it is there but I am probably staring myself blind at
the solution. If you guys need me to include my code (embarrassing!!) just
let me know.
Your help will be greatly appreciated!

For the data that cannot/should not be changed, quite simply do not accept
that value from the user. Just re-read its value from your own records.

Dear All,
I have stream data encrypted BASE64. My problem is that I must decode
this BASE64 to 8-bit unsigned array and I don't know how :( Have a

You mean encoded base64 stream data, right? Anyway, can you give us an example of the base64
data? PHP does have native support to encode/decode base64 data. However you're losing me with
the "decode to an 8-bit unsigned array" request. This might very well just be the decoded
base64 value that you then need manipluated into an array, maybe yes?

I have a simple php download script that streams a non-web-accessible file
to the browser using this generally accepted method:
header("Expires: 0");
header("Cache-Control: private");
header("Content-Type: application/save");
header("Content-Length: ".filesize($total) );
header("Content-Disposition: attachment; filename=".$file_Path);
header("Content-Transfer-Encoding: binary");
$fh = fopen($total, "rb");
fpassthru($fh);
While it works, this is fairly useless in my situation where files range
from 5mb to over 100mb, because due to fpassthru() or readfile() or whatever
method used to stream the data to the recipient, the 'save as'/'open' dialog
doesn't open until the entire file has been downloaded. This is very
impractical since the user has no clue how much has been downloaded / how
much longer is left, not to mention that on very large files (~75mb) apache
will actually freeze up and become unresponsive to all users (sending cpu
usage to 100%) for nearly 10 minutes or more, assumedly because it is still
reading the file (regardless of whether the 'stop' button has been clicked
or not).
With the last 2 lines commented out (fopen() and fpassthru()), the save-as
dialog opens instantly.. is there any way fopen/fpassthru() could be delayed
until after the user chooses to open or save the file ? How would you guys
go about handling large file downloads while keeping the files themselves
non-web-accessible (aka not a direct link/redirector)?
Any help would be appreciated.

Disclaimer - this is just an idea, I've never dealt with downloading that
big files.
If apache freezes because the file it's reading is too big to be handled
I'd suggest to try a chunked approach, not using fpassthrough or a single
file read. The reason is that for every system I/O the operating systems
get a chance to switch process context, and to allow cooperative multitasking.
Would go something like that:
define('CHUNKSIZE', 8192);
$fp = fopen($file, 'r') or die ("Cannot open $file");
header("Expires: 0");
header("Cache-Control: private");
header("Content-Type: application/save");
header("Content-Length: ".filesize($total) );
header("Content-Disposition: attachment; filename=".$file_Path);
header("Content-Transfer-Encoding: binary");
// --
while ($buffer = fread($fp, CHUNKSIZE)) {
echo $buffer;
}
fclose($fp);
You may need to experiment with the size of the chunks to keep up an
acceptable transfer rate. If you still encounter big holdups for other
processes you might consider using usleep() every 10th chunk or so, but use
your calculator to check how that would extend the overall transmission
time. For example, for a 100MB file, going to usleep for 50 msec after each
9kb chunk would mean that your process will sleep for 1.82 hours (!!) until
the file is delivered...

Is there a way to disable the call back function set by "ob_start"?
I tried:
ob_end_flush();
ob_end_clean();
ob_implicit_flush(true);
Nothing seams to work. I can't detect the call back function and I can't
prevent it either. The call back function is called no matter what!

You can put READONLY in your TEXTAREA tag

Hi all,
I have a app that enables the user to call data out of a mysql database into
textareas. They can then edit the data and update the database. There is one
field that I whant to stop them from changing. This field I also use in my
sql query when updating the table,ie. where variable='$variable'. So what I
did was simply this:
"<tr>\n";
print "\t<td>$variable</td>\n";
print "</tr>\n";
instead of:
print "<textarea name=variable rows=1
cols=10>".stripslashes($row['variable'])."</textarea><br>";
This definately stopped them from editing it but also disabled the mysql
query from working. Can anyone just give me a couple of ideas how I can make
this work.
Thanks

While this would probably keep the honest people honest (assuming it's
supported across all browsers), it won't stop anyone who wants to pollute
the database. What's to stop me making my own version of your form, without
READONLY, and submitting that?
If the OP doesn't want users to change the data in the field, he/she should
either display it so it's non-editable (i.e. in a <p>, or something), or
simply ignore any changes users make to it.
As a rule of thumb, *never* *ever* trust data that has left your server and
then come back, regardless of whether it's in a readonly textarea, a hidden
field, a cookie, whatever. Good programmers look both ways before crossing
one-way streets.
Cheers
