How are you proposing to connect? e.g. * FTP down the files, edit them, FTP them up again * mount the remote server via NFS * mount the remote server locally via SFTP * run the editor remotely: ssh -Y [EMAIL PROTECTED] etc. A conventional way would be to have a development environment locally, into which you transfer the files from the Linux server, edit them, TEST! them, and transfer back the changes (e.g. via FTP). -- Ross McKay, Toronto, NSW Australia "Let the laddie play wi the knife - he'll learn" - The Wee Book of Calvin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

SELECT User.UID, FirstName, Surname, Tel, Cell, Email, SUM(Points) AS TotalPoints FROM User INNER JOIN Tracker ON User.UID = Tracker.UID LEFT OUTER JOIN Winners ON User.UID = Winners.UID WHERE`Datetime` < DATE_SUB(CURRENT_TIMESTAMP(), INTERVAL -14 DAY) OR`Datetime` IS NULL GROUP BY User.UID, FirstName, Surname, Tel, Cell, Email The OUTER JOIN and the last line (OR `Datetime` IS NULL) is there so that your query will include results for users who have never won. I don't think it this is optimized (or how you could do so if needed) since the IS NULL condition will probably make the query use a table scan rather than an index.

An editor would be what you would use once you're already connected to the server (or once you've synchronized files with your local machine). I'm a command-line junkie, and a full-time Linux user (with the exception of my PDA and half of my laptop). So I SSH into the remote server and use 'vi' to edit the files. From the command line on an SSH connection, some of the editors you'll have available to you in almost all cases are vi/vim, pico/nano, and ed, among others. -- Forensic Services, Senior Unix Engineer 1+ (570-) 362-0283 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Cookie Trouble: getting the information back out...
Hi all,
I suspect I already know part of the answer to this, but I'm not sure
which way to go with it. I've got a project I'm working on and one of
the things it's got to do is set cookies and then read them later. When
the app was first written I was doing everything in PERL and cookies are
fairly straight-forward, however I'm finding cookies in PHP somewhat
problematic.
Setting the cookie is a snap, however getting the info back out is,
well... problematic.
this is basically what I'm doing, what I'm seeing in the cookie, and
what I'm getting back out.
Setting the cookie
==
$values = "blah|blah|blah";
setcookie("cookiename", $values, time()+$timevalue);
Inside the Cookie
==
Content: blah%7Cblah%7Cblah
Getting info Out Of Cookie
==
list($first,$second,$third) = explode("|", $values);
Cookie Test Page
==
if (isset($_COOKIE["cookiename"])){
list($first,$second,$third) = explode('|',$_COOKIE["cookiename"]);
echo "I found your cookie\n";
echo "The following Values were Contained in the cookie:
Username: $first
Password: $second
Type: $third\n";
}
else{
echo "I wasn't able to find your cookie.\n";
}
Now, I've constructed a cookie_test.php page to check things out and the
strange behavior I'm seeing is, upon first execution I get the "else"
block, but if I hit the browser's reload button I get the "if" block. At
first I thought the cookie wasn't being read at all because of weird
characters, but then upon reloading the page and seeing the "if" block
being displayed I'm thoroughly confused. It's gotta something simple I'm
missing.
and I swear if someone tells me to RTFM I'm gonna shit and go blind
cause I haven't got a clue as to "which" part of the FM to read
concerning this. :)
thanks,

[PHP] session var not changed if file not found error
This has baffled me all day on my FC6 php-5.1.6 based server. On a normal working page, I set a session variable at the top and another session variable in the middle of the page/script. This page has no errors nor missing links. So everything works great. Now, if I cause at least 1 image in the page to become missing on the server (ie, by deleting a .jpg file), then Apache logs the error as usual, ie: "File does not exist". But in addition, my two session variables seem to get deleted. If I put the picture(s) back, then no apache errors, and my session vars are set fine. I've even enabled detailed php error reporting and I get no errors. Is this normal session behavior? Please say no. Any ideas? I can't understand why missing links would cause a session variable's annihilation. -eric wood -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's by no means normal behavior, but that doesn't mean that what's happening for you isn't expected. Are you clicking a link to the image and getting the 404 error? If that's the case, it could be that your session is dying or expiring when you leave the sanctity of the page. Also, check and see what is included in the 404 response. Is it a custom page? Right-click the missing image and click "view image" to view the configured 404 response.

Um... Cookie data ISN'T available to the same script that sets it. If
you use setcookie(), all it does is send a header to the browser
immediately ahead of the output of your script telling the browser to
store those values in either memory or on disk. The value will not
appear in the $_COOKIE array until the browser requests the next page
and includes the Cookie: header as part of the request.
The part of the manual that applies is this line:
"Once the cookies have been set, they can be accessed on the next page
load with the $_COOKIE or $HTTP_COOKIE_VARS arrays."
$_SESSION variables are available immediately as soon as you set them.
The session cookie still isn't set on the client until the browser
processes the response headers at the end of the transaction, but the
values are already in the array and, if the session cookie works they
will be accessible on successive requests.

Hi all,
I suspect I already know part of the answer to this, but I'm not
sure which way to go with it. I've got a project I'm working on and
one of the things it's got to do is set cookies and then read them
later. When the app was first written I was doing everything in PERL
and cookies are fairly straight-forward, however I'm finding cookies
in PHP somewhat problematic.
Setting the cookie is a snap, however getting the info back out is,
well... problematic.
this is basically what I'm doing, what I'm seeing in the cookie, and
what I'm getting back out.
Setting the cookie
==
$values = "blah|blah|blah";
setcookie("cookiename", $values, time()+$timevalue);
Inside the Cookie
==
Content: blah%7Cblah%7Cblah
Getting info Out Of Cookie
==
list($first,$second,$third) = explode("|", $values);
Cookie Test Page
==
if (isset($_COOKIE["cookiename"])){
list($first,$second,$third) = explode('|',$_COOKIE["cookiename"]);
echo "I found your cookie\n";
echo "The following Values were Contained in the cookie:
Username: $first
Password: $second
Type: $third\n";
}
else{
echo "I wasn't able to find your cookie.\n";
}
Now, I've constructed a cookie_test.php page to check things out and
the strange behavior I'm seeing is, upon first execution I get the
"else" block, but if I hit the browser's reload button I get the
"if" block. At first I thought the cookie wasn't being read at all
because of weird characters, but then upon reloading the page and
seeing the "if" block being displayed I'm thoroughly confused. It's
gotta something simple I'm missing.
and I swear if someone tells me to RTFM I'm gonna shit and go blind
cause I haven't got a clue as to "which" part of the FM to read
concerning this. :)
thanks,

I have a custom 404 error page which starts the same session which is already in progress to show the current page. Now these 404 instances also do session updates in the header (because I'm using a template layout, you know). Therefor, the session file is obviously getting trampled on with these custom 404s.Wow, I would not have figured that out anytime soon. I just need to get less fancy with my 404 page, huh?

Is this block of code executed immediately after the cookie is
set? Sometimes PHP works too fast for its own good and the client
doesn't even realize it has a cookie yet. Try setting it with one
page and either sleep()'ing for a bit or forcing a link-click or page
refresh before checking for the cookie.
Conversely, $_SESSION data is much quicker, since the PHPSESSID
cookie is sent as soon as you initialize the session
(session_start()), and you can then immediately access the variables.

The "problem" that you are encountering is because the $_COOKIE array is "populated" when the script is executed. More then likely the other languages that you used, would allow you to set a cookie and then they would enter them into the "global" array for you, and not make you wait until the next page load. You could accomplish this yourself by making a wrapper function for the setcookie() function and have your function set the data using setcookie() and having it enter the data directly into the $_COOKIE array.
