Try changing those subscripts to keys:

It sounds like you need to normalize your data more. I can't imagine

usually better to break things into multiple tables where possible. If
you can, see if you can't restructure the database considerably - you'll
save yourself a great deal of work later.
Assuming you can't avoid setting that many variables at once, you can
use a PHP script like this to generate some statements programatically:

if (empty($_REQUEST['Table'])) {
die(Please provide a URL parameter Table);

$Table = mysql_escape_string($_REQUEST['Table']);

Since not all of the sites with PHP installed may use it (think hosting companies with default installs) and since IIS is often used to run other scripting tools (e.g. JSP, Cold Fusion, even PHP), I'm not going to try to adjust those numbers - it'll probably balance out.

Have you tried with the other HTTP headers for expiration? This is floating
around various places - the PHP manual, etc.
header(Expires: Mon, 26 Jul 1997 05:00:00 GMT); // Date in the past
header(Last-Modified: . gmdate(D, d M Y H:i:s) . GMT); //always modified
header(Cache-Control: no-cache, must-revalidate); // HTTP/1.1
header(Pragma: no-cache); // HTTP/1.0
If that doesn't work (IE/NS can be really buggy with caching - I once had a
problem where a page started returning a 500 error code and IE5 continued to
display the old version of that page, even though I had set the cache to check
every time), some alternatives come to mind:
- Embed some random variable in the URL. I think this is the cleanest way of
dealing with browsers which ignore the HTTP headers - simply start encoding
the session ID in your links or even something like DontCacheThisPage= .
time(). If the URLs are different, the browser won't cache them, which should
sidestep the issue.
If for some reason you can't do that and don't mind kludgy looking code:
- Use POST. It's ugly and nasty but the browsers are better about always
reloading pages which are the response to a POST request.
- Equally ugly, use JavaScript. When you change a document's location,
there's a parameter which if true will cause the browser to reload the page
even if it's cached. The least ugly way of doing this would be to write a
function and put it in a handler ('OnClick=return forceLoad('myurl');') so
that poeople w/o JS will still be able to use your pages.

Very strong agreement here. I think a lot of it depends on your environment.
Some have syntax highlighting and, better yet, syntax highlighting which will
prominently mark unbalanced braces, brackets, etc. Also very nice are things
like a brace-matching hotkey or options to highlight the matching open
character when you close it. If you have all of these tools to help show
syntax, I don't think you need as help from the source formatting. (The only
times I've liked having them on separate lines is when I've been working with
an editor which lacks this)
It also helps to properly indent things. I think code like this makes it pretty
easy to see which code is in which block:
if () {
...
if () {
if () {
// Do something
} else {
// Do something else
}
}
} else {

}
This is one thing I've always liked about Python. Forcing people to indent
consistently is a little harsh but it does have the advantage of making strange
code easier to decipher.

At a guess strtotime() is choking on the format MySQL used to return the date,
which would lead date() to fail as well.
The best way of handling this is to eliminate the need for your program to
worry about the day formats. Modify your mysql query so that instead of "SELECT
date" you have something like "SELECT UNIX_TIMESTAMP(date) AS date". Then you
can simply use date($row["date"]) directly. Alternately, you could use MySQL's
date formatting function to return the desired format directly. In either case,
you'll save a great deal of trouble by avoiding the need for PHP and MySQL to
be parsing each other's human-readable date formats.

put ob_start() at the top of your page and ob_end_flush() at the bottom. PHP
will store all of the output instead of sending it to the browser. If you put a
header("Location: foo"); exit; somewhere, that output will never be set.
(Take a look at the ob_* functions in the manual when you have a spare moment -
there's some pretty cool things you can do with them, particularly if you use

Try _level0 - that's what you'd need to replace the current movie.

Re: [PHP] SVG Scripting
In php.general, you wrote: I know (at least the claim) that PHP can do marvelous thing to Flash files (with libswf), presumably including "streaming" realtime feedback of a script's action. It can't. PHP can generate Flash files directly (and using Ming - it beats libswf handily - http://www.opaque.net/ming/) but cannot edit existing movies. Since Flash allows you to load other Flash movies on the fly, you can mix static and dynamically generated Flash movies into the same presentation. As an example, you might have a master interface which is carefully hand-tuned in Flash/LiveMotion and has specific areas where generated movies are loaded. Flash does offer the ability to load content from URLs, but not in a live fashion - you need Director / multi-user server for that. Since Director allows Flash objects, you could theoretically have your Flash interact with the server by sending communications through Director / MUS, but I haven't personally done this. Since Flash / Director performance will already be pathetic, introducing any sort of network overhead would probably reduce it to comical levels. Is there an existing library for SVG manipulation? Are there enthusiasts for this option? SVG files are XML, which means you can use either of PHP's native XML parsers to do low-level manipulation (the entire SVG + scripting option should be very similar to conventional HTML + CSS + JavaScript work). If you're doing much at all, I'd strongly recommend you develop the appropriate function libraries / objects using the underlying primitives. I'm doing this with some extensive Flash generation and it greatly civilizes things - you cannot plan ahead too much with this. If SWF is indicated, is there any known difference so far as libswf is concerned between Flash and LiveMotion generated SWF? libswf / ming can't edit existing files; if you're using LoadMovie, either one should be identical. On thing which may be an issue is Action Script - if LiveMotion doesn't support it or causes problems "navigating" the action script variable hierarchy, getting multiple movies to cooperate would be difficult and kludgy. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

How does the behind the scenes work by PHP exactly go? Does the PHP thread

1 Apache receives the request and determines that it's a PHP script.
2 PHP parses your code
3 PHP executes your code
4 PHP passes output back to Apache
5 Apache sends output to the browser (optionally through things like SSL)
6 Apache finishes request (e.g. logs it, closes a non-persistent connection)
The catch is that steps 4/5 may repeat - this depends on your output buffering
setup. PHP can wait and send everything when the script finishes, send output
in blocks or send every output from each echo/print immediately. (PHP can also
do things like compress that output on the fly, but that's a separate
conversation)
The reason that I'm asking this is I'm writing a statistics add-on for one of
my sites and was wondering whether the code below would give the time in
which PHP parses the code or in which the data gets streamed to the user.
You'd get the time needed to read the file and either send it or add it to the
output buffer (depending on your output buffer config as mentioned above). By
the time your code is executed, PHP will have already parsed your script (with
the exception of things like conditional / variable include()s and require()s),
so you'd only get the time required to execute the code, not parse it.
If you want to get round-trip times including transmission to the user, you'd
need to have some way of getting the user's browser to record a second request,
which introduces a lot of potential variables.
It might be interesting to see how something relying entirely on client-side
calculation like the code below would compare with other approaches (e.g.
Header("Location: measure.php?start=" . time()) where measure.php just does
$elapsed = time() - $start). It should remove almost all of the server-side
latency and, in theory, would give some reasonable indication of how long it
takes to transfer a file over the intermediate network connection, which would
give you a reasonable idea of available bandwidth.

seen by anything other than vi. Caveat programmer.)

Set a cookie on your site (perhaps the homepage?) and use code like this:

}
The idea is to set your code to assume that cookie support is disabled unless
it finds a cookie saying otherwise. That way it'll fail safely if someone
either doesn't have a cookie or their browser discards the cookie halfway
through. This may seem silly, but some people get *really* paranoid about
cookies. Combined with the increasingly good cookie management in modern
browsers and just about anything is possible - this is in fact the major
shortcoming to code like the above - it's possible for someone to accept one
cookie and deny another, so just being able to set a cookie once does not mean
that you will be able to set another.

The Regular Expression part of the online PHP manual has a lot of information
(http://www.php.net/manual/en/ref.pcre.php) but it does tend to assume you
already know what you need to do.
Basically, the regular expression in there matches any "a" where the character
before isn't an "a" (?!a) and the character after isn't an a (?!a). Any
matched characters are replaced with hyphens.
For your needs, '/(?!\n)\n(?!\n)/m' should work (the /m turns on multi-line
support, which is necessary since we're working with line breaking characters).
Note that you'll need to escape those backslashes in PHP if you use
doublequotes.

Re: [PHP] Parse WML to PHP?

How is it possible to parse a WML strin variable with a value="SO480", and

I get a error messages in M3gate WAP emulator, an UP SDK emulator telling me
this"unsupported content-type: text/html"
Yes. In fact, WML requests will behave just like normal HTML form requests. The
error you are receiving probably means that you need to set the mime-type for
the page you are returning:
header("Content-Type: text/vnd.wap.wml");
As a side note, consider testing your pages in Opera. Opera supports WML
reasonably well and has the side-benefit of being much easier to work with. If
you get an error, not all of the WAP emulators will show you the actual error
message. Many of them also have an annoying habit of caching pages even if you
ask them to clear the cache, which makes development rather more tedious than
it needs to be.

This approach can work and, properly done, work fairly well. However, a more elegant approach might be using mod_rewrite on Apache. You could write a regex that would convert addresses of the form /~username into /users/homepage.php?User=username internally. This would also have the advantage of leaving your existing 404 handling unchanged.

We are building a system to log user paths, and are thinking of harvesting PHP session objects to accomplish this. Has someone done the same? First, you probably want to have your code log to a database instead. The session files won't have the context information you want. Alternately, just turn on mod_usertrack in your Apache config and any decent log analysis program will be able to do that for you. However, if you do want to decipher those files, note the similarity between the contents of one and the output of serialize($HTTP_SESSION_VARS). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Has anyone ever had this problem before? PHP doesn't care about the bytes being sent, so there shouldn't be any special problems related to CSS. Have you verified whether or not any of what you expect is showing up in the generated HTML? At a guess, there's something slightly wrong in the generated code which is causing a display failure. If you're saving it through IE, some of the save options will have IE save it's internal parsed version (it's the same cause as the difference between View Source's code and View Partial Source's output), which could explain why that works. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] WML/WAP and PHP
On 16 Jan 2001 05:05:18 -0800, Rick Hodger [EMAIL PROTECTED] wrote:
Here's a fun little thing I discovered, possibly a bug in PHP itself?
To output a WAP page you must output a content-type header else the phone's
browser won't recognise the page. Dead simple. Use:
header("Content-type: text/vnd.wap.wml");
And all is well and good as long as you use echo/printf etc to output your
page. The second you deviate out of PHP and back to HTML the content-type
gets overwritten with a text/html, and so the page doesn't work. ASP used
to be able to cope with this, is it a bug or something I'm doing wrong?
Hmmm - you might need to start checking details of your configuration. I've had
no problems doing a lot of WML work in PHP and it's always correctly returned
the content-type I've set using header on 4.0.3pl1 (OpenBSD) and 4.0.3 / 4.0.4
(Win32).
Do you have anything like output buffering turned on? I doubt that's causing
the problem as I use output buffering semi-frequently[0] but it can't hurt to
check.
[0] neat hack - use ob_content_length() to tell when you've output almost as
much data as the phone can handle (find this by doing a browser detect) so you
can stop looping over a recordset and emit the Next/Prev page headers instead).

The easiest way of doing this would be to include a timestamp row in your database table; the edit form would be generated with the current value of that field. When they submit the form, your code can check to see if the time stamp that was current when the form was created is still valid and either process the request or give the user some sort of "Overwrite newer data (y/n)" prompt. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
