Re: [PHP] Cookie Guestion
From: Chris W [EMAIL PROTECTED] I am still new to web programing but I have a lot of experience in developing non web based applications. So I think I am a reasonably clever programmer and I have now done enough web programming that I understand the cookie mechanism. What I can't figure out is why so many people are paranoid about cookies. I don't really see much of anything that can be done with cookies to invade someones privacy. Am I missing something here? Exactly. The problem isn't the mechanism, it's the implementation by the programmer. If you save my favorite color in a cookie, no big deal. If you save my username and password in a cookie, that is a big deal. Cookies are sent back and forth between the web server and client in plain text, so it can be captured. The other thing to realize is that cookies can be changed; they come from the client. So if you set my id to 555 in a cookie and that determines who I am for you site, I can change the id to 333 and become another person. Again, it's a problem with the implementation by the program, not cookies themselves. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Cookie Guestion
From: Stuart [EMAIL PROTECTED] And don't forget the effect media hype had on their reputation. Cookies were portrayed as bad guys. As John says, they're not if they're used correctly, but it only takes one high-profile example of improper use to tarnish a reputation forever. And as that reputation is reduced, more people may turn them off. Another key point to realize is that the acceptance and transmittal of cookies is a client decision. You shouldn't rely on them or at least be aware of the possible problems if you do. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] php running as user apache
From: Nirnimesh [EMAIL PROTECTED] My question relates to using php for handling file uploads. Since php runs as user apache, using it to manage file uploads means that I need to give write permissions to the user apache, which is a near-to-nobody user, i.e. 0+w permissions. Now does that not mean that anyone who can run a php script on the server can write to my account? Yep. Is there any configuration setting that I need to fix, for this seems to me to be too trivial to be a bug, but still I know it can be used with fatal effects. Turn safe_mode on or put open_basedir (?) restrictions in effect.

Re: [PHP] preg_replce ' for use with mysql
From: Nirnimesh [EMAIL PROTECTED] How do I replace all ' with \' in php so that I'm able to use the mysql queries. Note that simply using: preg_replace(/'/, \', -1) is not what I'm looking for, for this does not help me. Let's say I take the address from a form and want to enter it into the database as it is. Now, if the user enters ' the above preg_replace will work but if the user himself enters \' , during replacing, the '\' introduced is nulled by the effect of the preceeding back-slash, and the mysql query becomes somthing like: mysq_insert (insert into students (id, address) values (3, '\\'')); How do I get around this problem? Is there any function which helps to insert everything into the mysql database as it is (does auto-escaping). Have you looked at the functions in the MySQL chapter? http://us2.php.net/manual/en/function.mysql-real-escape-string.php or just addslashes(). ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

From: Ryan A [EMAIL PROTECTED] Thanks for the very informative reply but I did try itproblem is, it seems to work with and without...thats why the confusion. I have one program like the one i outlined and the second one, like this: some html code goes here some output stuff goes here something ? php stuff? something something etc Which was working fine... thats why i got confused. Okay... I guess I could see that. The include is going to start in HTML mode. That's why the above works because you're starting with HTML. If the include file is all PHP code, then the file is still going to start in HTML mode, though. So you have to open PHP mode with ?php. Now, that being said, there was a discussion on here a while ago that you don't _really_ have to close PHP mode at the end of your file and there were certain pros and cons to doing so.

Re: [PHP] MySQL Question
From: John Taylor-Johnston [EMAIL PROTECTED]
Sorry, don't want to be off-topic, but have found something curious about
MySQL 4.0.16-standard.
It does not seem to prioritise properly. Searching for 'English Canada'
(as opposed to +English +Canada)
gives me all instances of both words but does not prioritize the display
order for
'English Canada' first and then 'English' then 'Canada'.
And how would you know that?
SELECT * FROM ccl_main WHERE MATCH
(YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,KW,AUS,GEO,AN,RB,CO) AGAINST ('English
Canada' IN BOOLEAN MODE)
ORDER BY id asc;
versus
SELECT * FROM ccl_main WHERE MATCH
(YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,KW,AUS,GEO,AN,RB,CO) AGAINST ('English
Canada' IN BOOLEAN MODE);
gives the same order.
Given these queries, you're not ordering by the relevance MySQL determines,
so you really don't know. You need to also use your MATCH ... AGAINST
condition in the SELECT columns and then order by that.
SELECT *, MATCH
(YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,KW,AUS,GEO,AN,RB,CO) AGAINST ('English
Canada' IN BOOLEAN MODE) AS relevancy FROM ccl_main WHERE MATCH
(YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,KW,AUS,GEO,AN,RB,CO) AGAINST ('English
Canada' IN BOOLEAN MODE) ORDER BY relevancy DESC;
Now I can't honestly say that MySQL determines English Canada is more
relevant than the two words found by themselves, but this will show you
whether it does or not.

Re: [PHP] PHP Includes and Echoes in Head Sections and Search Engines
From: Freedomware [EMAIL PROTECTED] I discovered that includes will apparently work just about anywhere, but echo functions apparently don't work with the title tag and meta tags; at least, I can't see the word Alaska in those locations when I click View Source in my browser. Look back over your code and you'll realize you set $statename _AFTER_ you include your file. So when the include file is run, $statename doesn't have a value. :) Also, do you know if text derived from includes causes any problems with search engines? My guess is no, because I can see the included words just fine when I click View Source. No, they won't. Search engines, just like browsers, only see the RESULT of your PHP code.

Re: [PHP] Defining own globals
From: Ville Mattila [EMAIL PROTECTED] Would it be possible to make all hard-coded variables beginning with $_ automatically global? I've found useful to set some variables per page to $_PAGE variable (for example $_PAGE['title'] etc) that would be nice to get available to all functions without extra procedures (like global command). The best way could be that $_ variables can't be defined by any user-input (forms, cookies etc)... Well, that's a explanation. I hope that someone would give any hint concerning this subject. :) You already have $GLOBALS as a global (scope wise) variable, just add to that if you want. $GLOBALS['page_title'] = 'etc'; Or you can add directly to $_GET, $_POST, etc, so long as it doesn't interfere with your forms. Maybe you need to use $_SESSION.

Re: [PHP] MySQL query
From: Ashley M. Kirchner [EMAIL PROTECTED] I need to query for record within a certain date stamp. The datetime field contains the createdon information that i need and is in the following format: 2004-01-11 21:40:50 What I'd like to do is search for records that are between 2004-01-09 and 2004-01-04. The time is to be ignored, just the date is what I need to search by. Is there a way to do this within an sql query, or do I have to do some PHP processing of the datetime field to get what I need? You'll want to do it in the query, although PHP could help a little. Even though you want the time to be ignored, the easiest way to do this is to actually search from 2004-01-09 00:00:00 through 2004-01-04 23:59:59. Since the 00:00:00 and 23:59:59 are constants you can just have PHP add them to the date string or hard code them into your query. Given that format, the query would be as simple as: SELECT * FROM table WHERE datetimefield BETWEEN $start AND $end Where $start is 2004-01-09 00:00:00 and $end is 2004-01-04 23:59:59 If you don't want to do that processing, then you'll need to use another method. SELECT * FROM table WHERE TO_DAYS(datetimefield) BETWEEN TO_DAYS($start) AND TO_DAYS($end) Where $start is 2004-01-09 and $end is 2004-01-04. There are other methods, too, but the end results is you need to take your datetimefield and get it into the same format as $start and $end. If you're using MySQL 4.1, there is a DATE() function (I think) that'll allow you to do this: SELECT * FROM table WHERE DATE(datetimefield) BETWEEN $start AND $end Where $start is 2004-01-09 and $end is 2004-01-04.

me. It has the following format:
[EMAIL PROTECTED]
Shouldn't this email pass? I've allowed for hyphens after the @
mark. Is it that there are two many periods?
You're only allowing hyphens in the first part of the address after the @
symbol, though, before the first period. Maybe your regex should be:
@([a-zA-Z0-9-]+\.)+[a-zA-Z.]
Just noticed that your period is not escaped, either, so you're actually
matching any character with the one that's outside of the [ and ] character
classes.

Re: [PHP] mysql_affected_rows() function
From: Tyler Longren [EMAIL PROTECTED] I don't think mysql_affected_rows() is working like it should for me. In the manual for mysql_affected_rows() it has this (Example 1): /* this should return the correct numbers of deleted records */ mysql_query(DELETE FROM mytable WHERE id 10); printf(Records deleted: %d\n, mysql_affected_rows()); However, when I do this: $delete_assignment = mysql_query(DELETE FROM consultingprojectassign WHERE workerid='$assigned[$i]'); printf(Records deleted: %d\n, mysql_affected_rows()); It always says Records deleted: 0. Even though the record was, indeed, deleted. I have an if statement also that says if mysql_affected_rows() 1, then print an error message. Well, since it always returns 0, no matter what, the error is always shown, even when the record is deleted. I can't see a reason why that wouldn't work.

Re: [PHP] mysql_affected_rows() function
From: Tyler Longren [EMAIL PROTECTED]
That's not the exact code. The exact code is below. Multiple workers
are being selected from a MULTIPLE select form field. I just use a
while loop do go through the selected ones to delete them individually.
PHP Version: 4.3.4
MySQL Version: 4.0.17
$i=0;
Don't put quotes around numbers. $i = 0; is all you need.
while ($i = $selected) {
You also don't need quotes around just a variable. ($i = $selected) is all
you need.
$delete_assignment = mysql_query(DELETE FROM webprojectassign WHERE
workerid='$assigned[$i]');
$i++;
}
if (mysql_affected_rows($delete_assignment) 1) {
$tpl-newBlock('message');
$tpl-assign(message,bERROR:/b There was an error deleting those
workers from the project.);
}
else {
$tpl-newBlock('message');
$tpl-assign(message,The workers have been deleted from the
project.);
}
The problem you're having is that your IF check of mysql_affected_rows() is
outside of your WHILE loop. So, you're executing a series of DELETE queries,
yet only checking mysql_affected_rows() for the very last one (which
evidently does not actually delete anything).
You could probably benifit from a DELETE FROM webprojectassign WHERE
worderid IN (1,2,3,45) syntax, too, so you only need to do a single query.
Since it's coming from a MULTIPLE select, a simple
$list = implode(',',$_POST['select_name']);
will create the list. Although you'd be better off looping through each one
making sure it's a number, though, to prevent any SQL injection attacks.
Ask if you need anymore info. :)

With most, being in the folder of my website, it's fine, i can just add $_SERVER['DOCUMENT_ROOT'], but there's a script I use to display the network statistics of an IRC network, which is located on a different server, so i can't use the $_SERVER['DOCUMENT_ROOT'], I'm wondering if anyone has an answer to this. I'm almost to the stage of just asking the script owner if I can have it located locally, so i can use the $_SERVER['DOCUMENT_ROOT'] variable. Ummm... if the page you're linking to isn't on your server, then you need to hard code the link to that page. If your script automatically uses $_SERVER['DOCUMENT_ROOT'] for every URL that's created, then you need to rewrite that script. That's the solution. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Headers Problem

All update-corrections-write.php does is write info to a database and includes update-corrections-input.php on the last line. So I'm still not understanding where the output from update-corrections-write.php is coming from. Sounds like you have a blank line as the first line in update-corrections-write.php.

Re: [PHP] Simple fwrite question
From: Hartley, Matt [EMAIL PROTECTED]
I am trying to have a counter in a file. With what I have below I get in
the $counterfile
0 + 01 = 01
01 + 01 = 012
012 + 01 = 01213
[snip]
/* Add 1 to the counter */
$counter = ($counter + '01');
You're adding a string. That doesn't make much sense. Just use $counter++;
or $counter = $counter + 1;
/* Verify counter file is writable */
if (is_writable($counterfile)); /* { */
if (!$handle = fopen($counterfile, 'a')) {
print Cannot open file ($counterfile);
exit;
}
/* Write to our counter file. */
if (!fwrite($handle, $counter)) {
print Cannot write to file ($counterfile);
exit;
}
fclose($handle);
[/snip]
How do I overwrite the existing value with my new value instead of it
adding
on after the past values?
Open the file in w (write) mode instead of a (append) mode. This will
clear the file and you can write your new value to it.
Note that if two peope hit your site at the same time, you'll have issues
here because they'll both try to open and read the file. You could end up
missing hits.
Why not approach it this way, which I've seen mentioned on here. Instead of
keeping an actual number in the file, just write a character to the file.
You can then use filesize() to determine how many hits are in the file.
?php
$fp = fopen('counter.txt','a');
fwrite($fp,'1');
fclose($fp);
echo 'This page viewed ' . filesize('counter.txt') . ' times.';
?
this counter decides what line to display in a sequence from a separate
file
what command can I use to tell it when $counter is @ the last line in my
tips file to reset to zero
I don't understand what you're asking here.

I think you should use the reverse solution : have a list of authorized

That's exactly it. You need to change your way of thinking. When ever you
are dealing with user input, you want to define what is GOOD and only allow
that. If you try to define what is BAD, you'll leave something out.
As for an answer:
$safe_foldername = preg_replace('/[^a-zA-Z0-9]/','',$unsafe_foldername);
That'll remove anything that's not a letter or number. Adapt to your needs.

This condition is true if there is no space, new line or tabulator in $val
Actually, the regular expression will match anything that is NOT a space,

So, if $val has anything that is NOT a space, newline, or tab in it, then
the ereg() function will return true.

Re: [PHP] Removing security-problematic chars from strings
From: Wouter van Vliet [EMAIL PROTECTED]
Let's make this personal: what would be your answer if I would advice the
friendly person to do this:
Heh.. I hope you're just kidding about making it personal... I was just
presenting security problems with various solutions.
?php
(..) $Content holds the string that you would want to be safe
# Create an array with allowed tags
$Allowed = Array('b', 'u', 'i', 'grin', 'foo');
# Compose var to send to strip_tags
$AllowedTags = '';
foreach($Allowed as $Tag) $AllowedTags .= ''.$Tag.'';
# Strip tags
$Content = strip_tags($Content, $AllowedTags);
# Make tags SAFE
$Content = preg_replace('/('.join($Allowed, '|').')([^]+)/', '$1',
$Content);
?
I didn't actually try that, but I'm sure it's fine. I seems to remove any
extra data in the tags you want to allow. It's good that you're still
stopping me from entering such devious and sinister code such as (.) (.)
and bar...
My point here is that I absolutely loath the strip_tags() function and think
it should be banished to the 12th circle of hell, meaning mainly ASP or JSP.
I can think of no valid reason where anyone would require that function.
In any program, if I enter the string foo, then I expect to either 1)
Receive an error or 2) See _exactly_ that string on any web page, email,
etc, showing my string. I do not want your program (speaking in general
terms here) to remove something from my string because it assumes it could
possibly be something bad.
I'm against letting users enter HTML in their data, also. I'd rather emply a
bbcode type solution, turning [b] into b, etc. This way, YOU set the rules
and say the user can do these _5_ things in this exact syntax. Otherwise
you're held at the mercy of the HTML and browser specs and hoping that even
just allowing b in the future won't have any security issues. When _you_
set the rules, you win.
So, my suggestions:
1. Just run everything through htmlentities(). If the users require advanced
formatting, provide a bbcode solution.
2. If you just _have to_ let users use HTML like b and i, then I'd use a
solution similar to what you have above, but drop the strip_tags.
$allowed_tags = array('b','i');
$safe_data = htmlentities($unsafe_data,ENT_QUOTES);
foreach($allowed_tags as $tag)
{ $formatted_data = preg_replace('/lt;' . $tag . 'gt;(.*)lt;\/' . $tag .
'gt;/Ui',$tag$1/$tag,$safe_data); }
Untested of course, but the only point that someone should take away is that
you should set the rules...

I'd rather emply a bbcode type solution, turning [b] into b, etc. I disagree with John here, but that's OK. :-) We seem to have different perspectives about this bbcode stuff. Personally, I see no need to define a new markup language that you intend to convert to HTML anyway. It is an unnecessary complication that yields no benefits from what I can see. If you run everything through htmlentities() but want some things interpreted, you can always use str_replace() to allow the very specific tags that you want. There's no need for regular expressions or risking the b onclick= type of stuff. Heh... my turn to disagree again. You can do a simple str_replace() to convert lt;bgt; back into b, but you're going to have to do it for each case. Also by doing that blindly, you can end up with orphaned tags affecting the rest of your page (making it all bold, for example). So, while I agree that adding another markup isn't always the best route, if you're not doing so, you need to include some regular expressions to account for all of the various implementations of the tags you want to allow.

I know you're working from a book, but for future reference, there's no
reason to serialize $products before storing it in the session. The whole
session array is going to be serialized at the end of the script, anyhow.
You can assign it directly to the session as an array and work with it as an
array on the following pages, too.
if (isset($_POST[form_products])) {
if (!empty($_SESSION[products])) {
$products = array_unique(
array_merge($_SESSION[products],

}
$_SESSION[products] = $products;
Then to recreate your $products array on other pages, you can either go the
easy route and just use the $_SESSION['products'] array... or use:
$products = $_SESSION['products'];
There's really no reason to have a $products variable to begin with,
actually. You can work directly with the $_SESSION['products'] variable,
adding and removing things from it and it'll always be available...

That'll just result in the number 1, though, since the conversion to float
will stop at the comma.
If you know that it's just going to be commas in there, a simple
str_replace(',','',$number) will get rid of the commas. Then PHP's type
juggling will take care of the rest for you and treat it like a FLOAT if it
needs to be. Or you can then use settype() to ensure it's a float.

Re: [PHP] File permissions on Windows, IIS
From: Chris Shiflett [EMAIL PROTECTED] --- Marius Røstad [EMAIL PROTECTED] wrote: I have a Windows XP pro [snip] How do I change file permissions to make it identical to the chmod 777 on Unix systems. With Windows, you probably right-click the file and go to properties, then you want to grant read, write, and execute privileges to user, group, and other. If you have anonymous browsing (default) enabled in IIS, then PHP (running within IIS) will run as the IUSR_* user (where * is generally the computer name). Do as Chris said and give the IUSR_* user permission to write to the directory where you're trying to use the file functions. If you're not using anonymous browsing and using integrated Windows Authentication, then you follow the same procedure except you need to give yourself permission to write to the folder in question. Basically, IIS almost runs as you and you must have permission to read the PHP file to begin with, then permission to write to the directory. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Random Function
You're code doesn't make sense. You're looking for 3 random numbers, between
1 and 3 inclusive. Umm.. 1,2,3.
Do you want them in a random order, or something?
Maybe the upper limit of rand() and how many numbers you're looking for

Subject: [PHP] Random Function
Hi, I have the following function that generates a random number, but the
key is it only generates the number once within the range you specify. So,
if you want a range of 5 numbers, it will give you 5 different numbers. My
problem is the function was set to start at 0, but I need it to start at 1,
so i made a change to the function (line 9) and now the script only works
every now and then. Can somebody look at it and see if they see why it would
be doing that? Thanks
?php
$s = array();
$n = 3;
function set_num() {
File random0.php saved.
$ cat random0.php
?php
$s = array();
$n = 3;
function set_num() {
global $s, $n;
$add = yes;
$ran = rand(1, $n);
if(count($s) 0) {
foreach($s as $sh) {
if($ran == $sh) {
$add = no;
}
}
}
if($add == yes) {
$s[] = $ran;
} else {
set_num();
}
}
while(count($s) = $n) {
set_num();

Re: [PHP] Having fits with input to array
From: Susan Ator [EMAIL PROTECTED]
For example, the command:
ps -C bash --no-headers -o
fname,state,vsz,start_time,flag,user,cputime,args
--cols 200
gives me the output of:
bash S 4396 Nov13 000 sator 00:00:00 -bash
bash S 4392 Nov13 000 sator 00:00:00 -bash
bash S 4396 Nov13 000 sator 00:00:00 -bash
The array I end up with using this code (where $pgm is bash):
$cmd = -C $pgm --no-headers -o
pid,fname,state,vsz,start_time,flag,user,cputime,args --cols 200;
$ps = `ps $cmd`;
$ps2 = ereg_replace(\n, ,, $ps);
eval(\$psArray = array(\$ps2););
print_r($psArray);
is:
Array ( [0] = bash sleeping 4396 Nov13 000 sator 00:00:00 -bash,bash
sleeping 4392 Nov13 000 sator 00:00:00 -bash,bash sleeping 4396 Nov13 000
sator 00:00:00 -bash )
where I need it to be:
Array (
[0] = bash S 4396 Nov13 000 sator 00:00:00 -bash
[1] = bash S 4392 Nov13 000 sator 00:00:00 -bash
[2] = bash S 4396 Nov13 000 sator 00:00:00 -bash
)
and the second array needs to be:
Array (
[0] = Array (
[0] = bash
[1] = S
[2] = 4396
[3] = Nov13
[4] = 000
[5] = sator
[6] = 00:00:00
[7] = -bash
)
etc...
)
THIS is what I am unable to do. Does anyone have any ideas?
$Array1 = array();
$Array2 = array();
$cmd = -C $pgm --no-headers -o
pid,fname,state,vsz,start_time,flag,user,cputime,args --cols 200;
$ps = `ps $cmd`;

Re: [PHP] variables from perl cgi into a php
From: mailing [EMAIL PROTECTED] I have a multiuser web based image managment application (the Perl script) and I want to add some accounting scripts (to be written in php). The guy that wrote the perl script is unavailable to work it in the perl script due to time constraints - so I was wondering if I can pass the variables - such as invoice amounts, the username (from the cookie) the image numbers that the invoice numbers relate to from the cgi into the perl script then into a mysql database. Any more help.Will virtual() do this sort of thing? Sounds like you want your Perl application to call a bit of PHP and pass PHP some variables. I was thinking of the other way around, PHP calling Perl. This is possible, though, I just don't know the Perl syntax to call a PHP file or make an HTTP request. Basically, you just want your Perl script to call a URL such as: accounting.php?amount=xxnumber=xxfoo=bar Then the PHP script can grab the URL variables and save them in the database. The same cookies available to the Perl script will be available to the PHP script (providing they're both on the same domain). Your PHP script wouldn't need to output anything, just do it's saving and then exit. Once you figure out the Perl - PHP bit, this should be easy (although it's a bad hack, overall!) ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] msession - giving me a hard time
From: Guillaume Dupuis [EMAIL PROTECTED] I've tried your suggestion and yes, I am transferring the SID variable to the next page... but I don't know if I am doing the this right. This is the code I use: --- ?php session_start(); $SID = session_id(); echo $SID; ? a href=http://192.0.1.7/use.session.php?SID=?php echo $SID?LinuxBox2/a --- If you used session_start($_GET['SID']); on your pages, this would work. The session ID that PHP is looking for is named PHPSESSID by default. That's why you should use the SID _constant_ a href=http://192.0.1.7/use.session.php??php echo SID; ?LinuxBox2/a If PHP doesn't pick up a session id, you'll just end up with a new one created the next time you call session_start(). So to recap: 1- Do I need session_start() at the beginning of each php pages? Yes, you need it on any page you want to access the session in. 2- Do I need msession_connect/create? Dunno about that... 3- Am I right to use $SID as a good tracking assumption (if I get the same SID thru several pages, this means msession works well???)? If you get the same session id after calling session_start() on your pages, then yes, it should be working. Using the above method with SID should get you this. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] session timeout
From: pete M [EMAIL PROTECTED] How do I set the session timeout - eg someone leaves a broweser for say half an hour then have to log in again.. As I'm on an intranet I want to increase ro 3 hours Exact method: Save the current time on each request in the session. On each request, check that time and if it's over 3 hours, then end the session / force them to log in again. Approx. Method: Look at the session.gc_maxlifetime setting in php.ini. This setting controlls when session files are cleaned up. If the files have not been accessed in gc_maxlifetime seconds when the garbage collection is initiated, then the file is deleted. Upon the next request, the session will be empty and the user should be forced to log in again. I say this is approx. because garbage collection is triggered on a random process based upon your requests. So files can run over the gc_maxlifetime setting sometimes if the collection isn't triggered. I just rely on this, though... it's close enough for government work. :) ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] msession - giving me a hard time
From: Guillaume Dupuis [EMAIL PROTECTED] Now, I am testing the interaction of 2+ servers working together. From SERVERA I create and echo the my SID using echo session_start(); echo session_id();echo $SID;, and then I follow a link (within the same browser session) to SERVERB and then do the exact same 3 calls. They give me different $SID ??? When you go from SERVERA to SERVERB, you do not carry over the same session ID, though. SERVERB, not seeing a session id passed to it, starts it's own session. You need to pass SID in the URL when linking to the different servers. No way around this. The session id can be carried in the cookies once you're operating on the same server, but when going from one server to another, you must manually pass it. a href=http://SERVERB??=SID?SERVERB/a ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

PHP Gurus,
If you say so...
I'm trying to put the results of a query into an array.
My code looks like this:

$query = SELECT datecolumn FROM table WHERE MONTH(datecolumn) = .
$currentMonth;
$result = mysql_query($query);
$numRows = mysql_num_rows($result);
for($i = 0; $i$numRows; $i++)

$workshops[$i] = mysql_fetch_row($result);
echo $workshops[$i] . br /;
}
echo The results of the array are - . $workshops[0] . and .
$workshops[1];
?
When I run this, the output to the screen says:
---
Array
Array
The results of the array are - Array and Array
---
Exactly what it should be. mysql_fetch_row returns an array, which you're
assiging to $workshops[0] and $workshops[1].
Try:
echo The results of the array are - . $workshops[0][0] . and .
$workshops[1][0];
Or, even better...
$query = SELECT datecolumn FROM table WHERE MONTH(datecolumn) = .
$currentMonth;
$result = mysql_query($query);
while($r = mysql_fetch_row($result))
{ $workshop[] = $r[0]; }
echo The results of the array are - . $workshops[0] . and .

Since this is one way hashes it cannot be decoded. Almost any argument that applies for/against /etc/password would apply to mysql password() as well. True, true.
