If lack of cron is the only thing holding you back, there's probably ways around that. You can make your PHP script available via the web, and then set up a home machine to request it every hour (assuming an 'always on' connection to the net). If you have a dialup, script your machine to dialup and request the page whenever you need to. Windows has the Task Scheduler, Mac (non-osx) has applescript (I think), and OSX and Linux have, well, everything. Otherwise, you could try an online cron service. Like: http://www.cronservice.com/ I have no idea how reliable they are, etc..., but it's likely cheaper than hosting with a new place.

A trick I picked up from someone on this list: Alabama Alaska Arizona END; ?> That's it! If $state is set to 'AZ', then the $$state line creates a variable called $AZ, and sets its value to ' selected="true"'. Running the code produces this HTML: Alabama Alaska Arizona This solution might be considered ugly for several reasons: * all sorts of warnings are thrown, one for each unset state variable * it's entirely un-obvious to the casual code-reviewer what's going on.

But he also mentioned a round-robin proxy messing things up. I've had personal experience with IP addresses from AOL clients changing with each new connection. If your AOL users click through your site a few times, it's possible that their IP address will change between those clicks, thus making even a temporary id based on the IP address unreliable, and perhaps frustrating if your site keeps 'forgetting' things about the user.

I don't think there's a way that you could force your server to push a new page onto an end-user's browser. However, you could replicate the behavior in a potentially annoying way: * serve up a page that has a meta-refresh of like, 5 or 10 seconds * that page includes an image, like "foo.jpg" * in your admin area, when you click "next", it does something to 'foo.jpg' (symlinks it to a new file, replaces the file, makes foo.jpg pull different stuff from a database, whatever) * next time the browser reloads due to the meta refresh, they see the new picture. It's not perfect, and there may be some cache issues that come into play. So you could tie your admin area to session ids, and have the reloading page have a dynamically determined image name. This might sidestep caching issues. Of course, there won't be immediate feedback to the user. They will have to wait a maximum of 5 seconds (or whatever) before they see your new image. The point is that you can't talk directly to the browser. You have to talk to the server, and then have the client periodically poll the server to see what new data it should get. I think. -- [ joel boonstra | [EMAIL PROTECTED] ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I would recommend using your .htaccess file, or ini_set, or something
else to set your include_path variable to contain
'/usr/home/sites/www.walkereffects.com/' or something like that. Your
include() call can then just look like:
and it'll work from anywhere, regardless of where the file that's doing
the including is located [1].
As a bonus, if you ever change hosts, or your host re-organizes its
directory structure, and all of your includes rely on the include_path,
simply re-set include_path, and your site works again.

[1] Of course, the order of directories in your include_path matters,
too. If it contains '.:/usr/home/sites/www.walkereffects.com/', then a
file matching in the current working directory will take precedence over
the one in your site root. So keep that in mind...

One solution (this may have already been mentioned on this thread; I haven't read it all) would be to let users upload a .zip (or .tar.gz) file over HTTP, and have your server uncompress it and (optionally) create a directory structure matching the contents of that .zip.

Where might these warnings be? I just perused this URL:

especially where it talks about the {} syntax, but I see no such
warnings of future deprecation. I also followed a provided link here:

but that also doesn't mention this warning. Is this in fact syntax that
will no longer work in some future version? If so, I'll start using {}

like this:
"This is a $variable embedded in a string"
might no longer work. If you have URLs, I'd love to read up on this.

[ straying even more off-topic... ] > It's doing this as a favor to you. If it displayed the "From" you'd know > less about the message than you know this way. I replied to Michael off-list, but since this popped up again... Pine uses a value called 'index-format' (configurable in the main config screen) to determine how and what to display for your email. Each piece of information (date, subject, author, etc...) that shows up in your index is represented by a 'token'. Pine has a stock set of tokens that it uses, but you can change the format to appear however you want. The default token is 'FROMORTO', which displays the 'from' address, unless 'From' is one of your own addresses (defined in pine's "alt-addresses" list); then it displays the 'To' value. To change this, simply define your own index-format, and use the 'FROM' token instead of 'FROMORTO'. More info is available by going to Pine's config screen (m, s, c), searching for 'index-format' (w index-format ), and hitting CTRL-G to bring up the help.

You should be able to use the fifth parameter ("additional parameters")
that was added in PHP 4.0.5 to properly set the envelope-sender, which
will cause the 'Return-Path' header to be set properly. Quick example:
';
$from = '[EMAIL PROTECTED]';
$subject = 'hey!';
$message = 'This is the message.';
mail($to, $subject, $message, "From: $from", "-f$from");
?>
Note that this doesn't do error checking on the status of the mail()
command -- it's just a quick example. There also may be sendmail config
things that prevent you from setting the Return-Path in this manner;
that's out of my area of expertise, so if the above doesn't work, I'm
not much more help...

Oh my, don't do that! If you only want to get the number of rows in a
table, don't bog down the MySQL server by doing a 'SELECT *' on it.
This could be a *ton* of data...
Why not use MySQL's built-in counting functionality:
$result = mysql_query('SELECT count(*) AS count FROM table');
$count_arr = mysql_fetch_assoc($result);
$count = $count_arr['count'];
MySQL will be able to simply count rows a lot faster than actually
SELECTing all of the data.
Of course, if you're counting rows just to find out what the next value
for an ID is, then, as you already said, you're doing the wrong thing.

What reason would you have for removing the quotes? There must be a better workaround than removing them. Regarding your question, it really depends on how you can operate on your HTML. Where is your HTML? Is it in a database, string, etc? Is it all in one chunk? That is, do you have stuff like this: This link has "quotes" that can't just have all quotes removed entirely from it? If you really need to remove quotes from attributes (and I don't think you do), and all of your HTML is in one big string, you're looking at a regular expression. Read up on them here: http://www.php.net/manual/en/pcre.pattern.syntax.php Yep, that's a lot of reading. But you should learn about regular expressions; they'll be useful all over the place. If you happen to be on a Linux/Unix/BSD/whatever machine that has man pages and perl installed, check out `man perlre`. Or read on-line here: http://www.perldoc.com/perl5.6.1/pod/perlre.html Some things to watch out for -- even if you do want to remove quotes from your attributes, I'm 100% sure you don't want to remove from *all* of them. Like this: Removing the quotes from the title attribute will likely break at least some browsers, if not all. So your regular expression needs to be able to handle that gracefully.

!= doesn't understand the glob (*) character, so the easiest way to make
your example work is to use a regular expression match. Something like:
if ($files != "." && $files != ".." && !preg_match("/\.config$/", $files)) {
should do the trick. However, if you anticipate adding any more filters
on the listing (.cfg, .txt, .conf, etc...) you might want to come up
with a more general way to add filters besides simply tacking on stuff
with &&. One thought might be to keep an array of patterns, and do a
match on the whole array. When a new file needs to be filtered, simply
add an entry to the array, keeping your code more-or-less clean.
It's up to you, though.

Do you know if your hosting company has a multi-webserver setup? If so, do they have a shared /tmp directory (where PHP stores session information), or is it unique to each server? If your hosting company has many different webservers, each reload might hit a different one, and each may or may not have your session information in its /tmp directory.

[PHP] RE: Why $ on variable names?
> That's the way the language designers did it, and there's LOTS of > PRODUCTION code out > there that uses it. > > See also the precedence of PERL. Well, perl and PHP use the $ for slightly different reasons, it seems. In perl, the *thing* in front of a variable name ($, @, %) indicates what context the variable is being used in (scalar, list, hash). Depending on what you want your variable to do, using a different character makes all the difference. The leading character is not a part of the variable name. PHP seems to use the $ more for readability, and possibly for making the language easier to parse (and, of course, the aforementioned string-embedding). Since all variable types (scalars, arrays, objects) seem to use the $, it seems more for syntactic uses and less as something that changes how the object behaves. However, I like having it there. It (as someone else mentioned) helps me quickly see where variables are used, both in and out of strings. It also probably helps syntax-highlighting text editors read the code more quickly, although it may be just as easy without. All I know is when I think back to programming C++, I can't imagine how I could deal with variables that didn't have something in front of them to separate them from barewords.

I would recommend not simply doing a select *, but rather specifying
which columns you want. That way, if your database schema changes
(e.g., you add two more columns), your code won't break.

And, responding to myself, specifying your columns is also good practice because MySQL makes no guarantees about the order that columns are returned when you say "SELECT *". Today, it may well be the order that you specified when you created your table. With the next upgrade, it may be alphabetical order, or by column type, or some other order that the software chooses. If you specify column names in your SELECT statement, you don't need to worry about it.

No need to explicitly state "true" and "false". Just negate the result

Is there any way you can save state? That is, can you keep track of who got the last one, and use that to determine who should get the next one? Otherwise, why not just rand() between 1 and 2? rand(1,2) will, on average, give you as many 1s as 2s (like flipping a coin). There will likely be runs of 1 or 2, but over time, doing rand() with two possible values versus rand() with 501 values will not be significantly different. In fact, since there is one more odd than even between 1 and 501 (inclusive), you will be getting slightly more odds than evens with that range than you will with a range of 1 and 2. Also, which PHP version are you using? If before 4.2.0, you should seed the random number generator with srand().

preg_replace expects the first argument to be a pattern, which should be
enclosed in forward slashes ("//"). So your $url variable should be
surrounded with slashes. You have single quotes in your $url variable,
but I don't think that PHP behaves like perl in letting you use
whichever delimiter you choose. Try replacing the single quotes with
forward slashes.
Additionally, if you're only doing a simple string substitution, you
should use str_replace instead:
http://php.net/str_replace
You won't need the "/" delimiters, and it will be faster than using
preg_replace.

I'm guessing that the .css file will be used in the traditional way:

Now, it's the browser that's fetching the .css file, so the header()
call isn't a problem at all. The browser simply performs a separate
request for that file, so its header() information is sent in response
to that request.

Often arrays have things added or removed as you're coding -- not having to worry about removing a trailing comma for an element that is now the last one, or adding one to previous elements when adding items to the list is a small but useful timesaver.

[PHP] function scope question
Hello,
I wrote a PHP class to display an HTML calendar, and then wrote a subclass
of it for a specific project I'm working on. Here is the entirety of the
subclass:
// create our new sub-class of the calendar
class rantCal extends calendar {
function get_link($day) {
$link = "";
if (valid_date($this->my_year, $this->my_month, $day)) {
if (rant_exists($this->my_year, $this->my_month, $day)) {
$link = "index.php?date=$this->my_year-$this->my_month-$day";
}
}
return $link;
}
}
Basically, it's used to determine if a given date should be linked or not.
When I wrote it, I didn't expect it to work, since these two function:
valid_date()
rant_exists()
are defined completely outside of the class. In fact, they're defined in
a functions file that I include (with include()) above where I define my
rantCal class. Shouldn't their names not be recognized within this class?
I was assuming that a class was entirely self-contained, so it can't know
about functions defined outside its scope. However, it works just fine
(that is, the functions get called), which is helpful, but it doesn't seem
like the way things should work.
Am I completely wrong? I seem to recall that this sort of thing should
work in a more strict OO language, like C++.
I'm using PHP 4.0.6, if that's important.

That's not what the original question was, though. David (I think, unless

with an object of ClassB:

The answer to this question, unless my OOP theory is gone, is that you
can't, unless ClassB is an extension of classA.
So if you have:
class ClassA {
// some vars
function get_contents() {
// some stuff
return $something;
}
}
and then:
class ClassB extends ClassA {
// some vars
function display_contents() {
print $this->get_contents();
}
}
Then you're good. Otherwise, I don't think it's possible...

HTML treats bunches of whitespace as one space. Look at the source of the page; you'll see that it's doing what it should.

Re: [PHP] why doesnt this work???
Hello,
I read a ton of replies to this already, and there was a lot of good
advice.
However, it should be worth noting (and I don't think anyone did already)
that you have a misspelling in this code:
> $password = "";
> // . . .
> $query = "select * from medlemmer where bruker = '$bruker' and passord =
> '$passord'";
> // . . .
> if( $line[1]='$bruker' and $line[2]='$passord') echo "hei $bruker.";
You initialize the variable as $password, but refer to it as $passord (no
'w'). Maybe that was just a typo in the email, but that will definitely
be a problem in the code, too.
Of course, all the other advice ('==' instead of '=', '&&' instead of
'and', etc...) should be heeded as well...

You're properly printing out the Content-type header, but not the actual
image data. You need to get the get the binary data (probably using a
binary-safe read) from the image file you want to display (in $url), and
then print that data out after the content-type header.
Right now, a browser would get sent a content-type header for a gif, and
then the following string:
http://www.mysite.com/myimage.gif
and that's not valid contents for a .gif file.

This may be possible with Apache 2.0 and greater, once it's in stable release (perhaps it is already). It would allow the server to perform multiple passes on documents, thus allowing your PHP script to execute and output SSI, which would then get parsed by the server and be executed, again. Why you would need this, I don't know. As people already mentioned, SSI's very limited capabilities should all be available in PHP.

Why not use php's include_path setting? No need to define constants, no
need to worry about the location of your script relative to the document
root, and it works with more functions than just include() and
require().
I have found it to be the cleanest, most reliable, and most portable way
to deal with file paths.

Sorry, I should have been more specific.
I was implying that you would set the include_path to include your
document_root for your whole site, using httpd.conf, .htaccess, or
ini_set() (.htaccess probably being the easiest).
# httpd.conf or .htaccess:
php_value include_path '/path/to/document/root:.'
# ini_set():
ini_set('include_path', "{$_SERVER['DOCUMENT_ROOT']}:.");
You could also modify the ini_set() method to append document_root to
your current include_path setting, using the PHP_INCLUDE_PATH constant.
I think.
But you're right, you can't rely on the default include_path setting to
contain anything useful. If you set it manually, though, it can contain
whatever you want.
Unless I'm misunderstanding what you're saying...

Replying to myself, it appears that PHP >= 4.3.0 has a family of
functions specifically for tweaking include_path:
http://www.php.net/manual/en/function.set-include-path.php
When using ini_set() or something similar to tweak the include_path, I
would recommend using it in conjunction with a file that is
auto-prepended to all of your .php scripts (assuming you want all of
your scripts to use the same include_path):
# in .htaccess
php_value auto_prepend_file "path/to/init.php"
# init.php
set_include_path('/new/include/path');
You can of course put other stuff that needs to apply to all .php files
in init.php, too.

This is accurate (the explanation from webdesign-l). Try it yourself:
===
$> telnet www.yourserver.com 80
Trying 123.456.789.000...
Connected to www.yourserver.com.
Escape character is '^]'.

Server: GoGoGadgetWebserver/0.3
Location: http://www.example.com/
Connection: close
Content-Type: text/html
Connection closed by foreign host.
===
Assuming redir.php contains a header() call that sends "Location:", the
bot will see something like that. It's up to them to parse that,
determine the status code (302, in this case), and decide what to do
with it. Browsers just do this transparently.
> What say you, PHP list? Would it be better (in terms of search engine

Do neither. Create excellent content, structured well, and the search
engines will reward you for this. Try to trick them, and they will
likely figure it out and penalize you.
However, if you're asking whether or not Google can determine if you're
using include() to serve up different content based on the UserAgent or
perhaps the IP address, then no, bots can't figure that out. Unless
they switch useragents/IPs and compare the results that they get. Or
unless a human complains that the listing is innacurate. etc...

The reason it works after you put die() after calling your first
header() is because once you send the location header, you can't send
other stuff. Using die() causes script execution to end, which lets the
header work. So put something in there that causes script execution to
end (e.g., exit()).
The proper code (including the properly-formed URL mentioned by others)
is something like:
if($foo == 'something'){
header('Location: http://www.example.com/to_another_page.php') ;
exit();
}else
{
do another thing in here
}
header('Location: http://www.example.com/to_previous_page.php');
exit(); // for good measure

Hopefully you're aware that $HTTP_USER_AGENT is an unreliable variable,
in that it is sent by the client, and can contain virtually anything.
I saw a response letting you know how to do this, but I would recommend
not sending people to different pages based on which browser/OS they're
using.
The most I would use $HTTP_USER_AGENT for is if I'm presenting a list of
different OSes (say, for links to OS-specific downloads), and I want to
select an intelligent default.
It should be possible to use CSS/(X)HTML to present your content in a
way that is accessible to whichever browser accesses your site. IMHO,

Re: [PHP] Browser Detection another page
me big sites that have decided that a CSS design is viable: http://msn.espn.go.com/ http://news.com.com/ http://www.sprintpcs.com/ I'm not an expert (unfortunately) on the specifics of how to acheive this sort of a design. I'd recommend checking out Jeffrey Zeldman's book "Designing With Web Standards" as a great overview on how to get started on standards-based design. One very brief example of the sorts of thing you could to do allow browsers to use your site would be to use the @import CSS directive to include your stylesheet. Newer browsers can handle this; older ones can't. So when I go to http://csszengarden.com/ in Mozilla, I get a nice site, because it understands @import. When I go there in Netscape 4.78, I get the HTML (which is usable), but not the design. For discussion: http://css-discuss.incutio.com/?page=ImportHack (and I hear that's a great email list for specific CSS-related topics) The key difference in serving designs in this manner is that you are not coding for browsers or platforms; you are coding for capabilities and standards. It's pretty clear that browser rendering/standards support is only getting better, and that the number/variety of browsers is growing. > Could you throw in another 2 cents? :o) I guess that was more like 10 cents. Feel free to continue this off-list if you want to discuss more. This really doesn't have much to do with PHP anymore ;) joel -- [ joel boonstra | gospelcom.net ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Note that characters within square brackets don't need to have the | to
separate them; it's a character class, so it will match any character
within the brackets:
if (preg_match('//i', $dah, $matches)) {
Also, it's probably good to put a non-greedy modifier after the *s to
prevent .* from matching too much. Compare:
';
$doo[2] = "";
foreach ($doo as $dah) {
if (preg_match('//i', $dah, $matches)) {
print_r($matches);
}
# adding ? after the *
if (preg_match('//ig', $dah, $matches)) {
print_r($matches);
}
}
?>
'Course, it still doesn't match multiple images in one line.
preg_match_all() could probably help out there.

True, PDAs can't generally handle the same size/number of graphics that a desktop browser can. But what about the Treo? The Sidekick? The Zaurus? Do those get browser-detected as well? Or will they still get the same designed-for-desktop site that all non-WinCE devices get? As an alternative, use the same (X)HTML, and design an alternate stylesheet for handhelds, using the CSS media type options: http://www.w3.org/TR/REC-CSS2/media.html#media-types Now you can maintain the same content, and just have two different stylesheets. 'Course, this is the ideal; it's probably the case that not all handheld browsers recognize media="handheld" like they should. Perhaps the @import rule trick will work, as well. There is some discussion on alistapart: http://www.alistapart.com/articles/slashdot2/ about handheld emulators, and how XHTML/CSS-designed sites appear on them. However, this is way way OT now, and should probably be carried on offlist. Or, better yet, I bet css-discuss can provide tips for using CSS to support handheld browsers, without having to duplicate content or do browser sniffing. -- [ joel boonstra | gospelcom.net ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Version #2 involved an identical database structure, or multiple database fields, or some sort of redundant data storage that mirrors the HTML database structure. The bigger problem to me seemed to be the complexity introduced into the database, not the extra storage space required. This solves the script run problem (only runs once), and lets the database remain as originally planned. The point is that the XHTML version is only necessary for display on the finished webpage, and the simple HTML version is only necessary for editing in the administrative interface. Publishing static XHTML files eliminates the need to do database interactivity on each page request (after all, the content isn't going to change with each request, is it?) and keeping the HTML in the database lets the admin. interface be as interactive and dynamic as is necessary.

To remove the underlying problem, changes in Apache would have to be made. The problem is that mod_php (not necessarily PHP as CGI) runs as the same user that Apache runs as. There is nothing PHP developers can do about that. This means (assuming mod_php) that when your hosted website runs a PHP script, and another website hosted by the same company runs a PHP script, both scripts are running as the same username. This opens any number of potential for malicious or accidental access to others files. Additionally, all system calls will be called as the same user, so the server's built-in mechanisms for determining user permissions are useless. One solution is to run PHP as CGI and use suexec to cause PHP scripts to be run as specific usernames. However, there are speed and integration advantages to running as mod_php, so using CGI isn't necessarily the best solution. The other is to use safe mode, which does what it can to help solve security concerns by relying on file permissions to determine what can accessed, and by restricting things like system calls that are too potentially harmful. It's not the right way to solve the problem (as they mention on the safe mode page), but solving at the Apache level[1] may or may not be viable. Safe mode is not necessarily appropriate for all situations; on personal servers, or single-user websites, it can be too restrictive. However, for hosting companies, as others have said, not using it has the potential to make your customers very unhappy when someone else's poorly-coded script starts wreaking havoc. [1] Apache 2's "perchild" MPM looks interesting: http://httpd.apache.org/docs-2.0/mod/perchild.html When it's functional, I'm not sure if it will eliminate the need for safe mode or not. It still appears that for large hosts, managing the UIDs might be difficult. I'm by no means an apache admin, but if my hosting company has 300 vhosts, it seems like you'd have to start at least that many servers, and that only one instance will be tied to a vhost (so if one vhost is getting lots of traffic, and one is getting only a little, there won't be spare servers around to balance things out). I'm basing that all on what I read at Apache's site, so I may well be wrong. joel -- [ joel boonstra | gospelcom.net ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

ORDER BY will definitely help, but GROUP BY will not be useful here.
The original query results looked like:
TOPIC QUESTIONANSWER
1 A B
1 C D
1 E F
2 G H
1 I J
2 K L
3 M N
By adding "ORDER BY topic" or something similar[1] to the query, you can
get your results to look like this:
TOPIC QUESTIONANSWER
1 A B
1 C D
1 E F
1 I J
2 G H
2 K L
3 M N
I'd also recommend adding a secondary ORDER BY to make sure that
QUESTION is ordered properly. The example results wouldn't change, but
presumably those aren't ordered yet.
However, GROUP BY will do unexpected things to the results, since the
point of this query isn't to perform aggregate operations[2] on rows
(SUM, AVG, etc...), it's simply to display all the data for all
questions. If you do a GROUP BY, MySQL won't quite know what to do.
To get this to display properly, you'll want to keep track of what topic
you previously displayed in your loop, and only display a new one if the
previous one is different. Something like:
';
while ($row = mysql_fetch_assoc($results)) {
# for convenient variable names
extract($row);
# only show the header if the topic has changed
if ($topic != $last_topic) {
print ''.$topic.'';
}
print " $question$answer";
# store the topic for next time around
$last_topic = $topic;
}
print '';
?>

Hrm... why the switch() statement? I can see the need for validating
user-submitted data, but to make it a little more flexible, maybe
something like this:
To add more valid actions, you can just extend the array of valid
actions, rather than adding clauses to the switch statement.

As mentioned in another post, the Return-Path header can and usually is
overwritten by sendmail when it does the actual sending.
In addition to a previous suggestion, one way to reliably set that
header is to use phpmailer (http://phpmailer.sourceforge.net/) which has
the option of using an smtp server rather than sendmail directly.

The new hosting company's web servers don't appear to have their servers
setup to parse *.cgi files through CGI. They will need to fix that, or
he will need to move ganttChart.cgi into a directory that is setup to
handle CGI files -- sometimes you'll have a cgi-bin directory for this

In addition to the other suggestions, you might use extract() on $_POST:
http://www.php.net/extract
To be sure you know where you're getting your variables, you could add a
prefix to the variable names ('p', for example), so your vars would look
like:
$p_username
$p_password
$p_password2
etc...
I personally would prefer this over register_globals because it gives me
more convenient access to my variables, but I don't have the danger of
$_POST variables overwriting my existing ones (assuming I don't name
other variables with the p_ prefix, use the proper extract() flags, etc.).
