Yes, I am doing the grid --basically 100 radio buttons, that is ten comments that must be ranked from 1 to 10. Ugh. If you absolutely can't use Javascript, here's an idea: Present this question by itself as two lists: on top an unordered list of options, on bottom an ordered list (initially empty). Each item will have a set of links (icons maybe) to place this item next (if in the top list) or move up/down or remove the item (if in the ordered list). The user would click the links to move around the choices until he/she is ready to submit that question: add items: _eggs_ , _milk_ 1 candy _remove_ 2 3 -- 1 candy _remove_ _down_ 2 eggs _remove_ _up_ _down_ 3 milk _remove_ _up_ The nice thing is, each page you generate would be a valid response so you, nor the user, has to worry about, eg. submitting two items in 3rd place. It would also be /much/ simpler for the user to rearrange items since he/she no longer has the burden of renumbering each choice. You could potentially add Javascript onto this setup so that the movement would be updated purely on the page or with only a minimal XMLHTTPRequest call. Another idea: just require Javascript and save yourself reinventing the wheel. http://www.phpsurveyor.org/index.php is a mature survey system with ranking question types and nice data export options.

Not really. Sending a Location: header says, this page is temporarily
moved and the browser has to send a 2nd request for the new location.
Whether redirecting via PHP (header), javascript or meta-refresh, these all
needlessly force the browser to ask for the page twice, and potentially
cause bookmarking/spidering issues when used for the home page. Amazon
does this and it's annoying; some browsers just will not remember the
plain old http://amazon.com/; that you typed in because only a redirect
lives there.
With a proper server config, the contents of start.php would be immediately
sent to the browser. This is good. But if you can't set this on the server,
this simple PHP script (index.php) does the same thing:
?php require 'start.php'; ?

[PHP] massive find/replace on MySQL db
Hello, I've inherited a MySQL db (4MB on disk) that's riddled with inconsistent storage of character entities from being pasted from Word. At very least I hope to convert all quotes #145; - #148; to HTML's #34; and #39;. I imagine I'll run a big query, save the id's needing edit in a file than have a script hit all those, pulling text/varchar fields, using strtr() to make changes and updating. I suppose I could have the script just do the 1st 10 in the file, remove those from the file, then I'd recall the script. I imagine this might take 10/20 minutes. Am I missing some internal MySQL feature that would do this? Hmm, what about running strtr() on a mysqldump-ed file? Any advice/links appreciated. Please CC me. Thanks a lot!

Andre,
Sorry to chime in so late, but IMO, be more concerned with
saving output for the last step in execution, because once it's echoed
out, there's no turning back or sending headers or a redirect.. Have
functions return strings instead of echo them (and take advantage of
syntax for more readable string building), build up a document
into variables, send out at very end.
Some home-grown example code might be useful:
?php
//setup session, DB, some common functions
require_once(setup_session.php);
require_once(create_DB_object_instance.php);
require_once(html_building_functions.php);
// start building string array for later output
$Template[title] = query results;
// if DB problems, load content, output, quit.
if (!$dbi-connect()) {
$Template[main_content] =
join('',file(DB_down_message.html,1));
include(main_template.php);
exit(0);
}
// build result table HTML
$result_table = open_result_table();
$dbi-run_query(SELECT ..);
while ($row = $dbi-next_row_array()) {
$result_table .= EOD
tr
td{$row[guns]}/td
td{$row[butter]}/td
/tr
EOD;
}
$result_table .= /table\n;
// load results content
$results_copy = join('',file(about_results.html,1));
$Template[main_content] .= EOD
h1Query Results/h1
$result_table
h2About Results/h2
$results_copy
EOD;
if (//need to go elsewhere) {
header(Location: http://elsewhere;);
exit(0);
}
$_SESSION['last_accessed'] = $PHP_SELF;
setcookie(//something);
include(main_template.php);
?
Point is, at any point in execution cookies or headers can be sent or
content changed. You end up with most content in seperate files and
script logic/execution very easy to understand/debug. Stick a watch
echo anywhere in the code and it pops up at the top of the browser
window.
For the above code, main_template.php is a full HTML document (only
HTML editor needed) with PHP tags in just a few spots to echo elements
of the $Template array:
!DOCTYPE ...
html
head
title?php echo $Template['title'] ?/title
/head
body
?php echo $Template['main_content'] ?
/body
/html

There's an urban legend saying that switching php tags on and off would

Content outside PHP tags gets to skip the parser. From the manual:
..for outputting large blocks of text, dropping out of PHP parsing mode
is generally more efficient than sending all of the text through
echo() or print() or somesuch.

Just as a note, recent builds of Mozilla have a cookie manager that is the best for seeing exactly what's going on with your cookies. You can list by name or host and see all the properties of each. Know when your session cookies are sent/deleted, know if PHP is allowing use of the same SESSID in a new session.. BTW the rest of the browser is tops as well.

[PHP] eating mySQL result rows 1 by 1.. a better way?
Hello,
On my site I paginate query results by limiting rows output to a
value, say LIMIT, and then the 2nd, 3rd pages run the same query with
$skip=LIMIT, $skip=(LIMIT*2) value posted back. I use the following
code to skip these result rows, which is just fetching the next row
to an unused array.
//if there are rows to skip
if ($result_rows $rows_to_skip) {
while ( $rows_to_skip ) {
// eat a row
mysql_fetch_array($result);
$rows_to_skip--;
$total_results_shown++;
}
}
Can I make this more efficient? Is there a way to eliminate this data
before it leaves the mySQL server (and would it be faster)?
If it makes any difference the average result row is probably around 40-50
bytes but some of these queries can return up to 850 rows..

[PHP] sessions not so secure..solution?
Hello, I'm building an e-commerce site which uses sessions to hold my $cart object. This works great but I've two worries: 1) When the user connects through our secure hostname, can I ensure the browser will send the server the cookie (w/ SESSID)? The user will shop through domain.com and checkout via https:secure.domain.com. (haven't got cert yet) 2) While the user shops the SESSID is thrown around insecurely (no big deal, just a cart). But when I move the user to a secure server to get sensitive info a resourceful hacker could also go to the checkout script using this SESSID and 'confirm' the real user's personal details (kept in another registered session object). If I can't keep the user's details in the old session, can I delete the old session and copy the cart to a new session? Should I do this anytime the user goes back to the insecure site and returns to finish checking out? As an alternative, would there be any problems with keeping the IP of the user in a session variable for further authentication? I assume I'd record the IP immediately upon checking in at the secure server then enforcing this per request. That way, worst case scenario the hackers gets a SESSID and heads to checkout first, server restricts real user from accessing (because of different IP). This is my first time coding for a secure server and my first post here as well..

AS Well, use GnuPG. Then you can use PGP. And what you stated above is
Just some advice if you go with GPG and you don't have root/chown

Since you'll create your keyring under your user, you'll likely have
to run PHP as a CGI so that it has access to your keyrings and can use
a temp file. You might get around this by making your keyrings
group-readable (for the PHP-user), but obviously w/ that *any* PHP
user on your server could potentially access your private key. Then
again, if you only need to /send/ encrypted messages and you don't
include the server's key in the recipient list, it's no big deal
because the worst they could do is send messages to people signed as
your server. They couldn't get the data.
In windows I found the easiest way to decode GPG-ed email from the server was
to install PGP6.5, the Bat! email client and generate a key w/o using
the IDEA algorithm. Import this pub key into GPG on the server. There
are GPG tools for windows but I found Win mail clients still don't
support GPG anywhere near as much as PGP. The Bat! can use GPG to
decrypt fine, but you have to enter your username and passphrase for
EVERY message. The Bat!s PGP plugin allows uid/passphrase cacheing for
a specified period of time, which was enough for me to switch.
A snippet of the code I'm using to encrypt:
//this already has the plaintext message
$plainfile = /home/me/.gnupg/temp/.$this-hash.'plain';
//this will be created having the encrypted version
$gpgedfile = /home/me/.gnupg/temp/.$this-hash.'gpg';
//shell command to call gpg
$command = gpg -e -q --no-secmem-warning ;
//encrypt for my array of recipients
foreach ($this-recipients as $recipient) {
$command .= -r '$recipient' ;
}
//target will be ascii-armored and stderr sent to stdout
$command .= -ao '$gpgedfile' '$plainfile' 21;
//environment variable for GPG
putenv(GNUPGHOME=/home/me/.gnupg);
//execute command
$this-error = exec($command);
//check error / read in $gpgedfile, unlink the files..
