Because that wouldn't work :)
This variable may contain stuff like "nl,en-us;q=0.7,en;q=0.3". You'll
need to do something with this variable first to use
array_key_exists (or as you do, isset). That said, I agree that
strstr() might not be the best solution.
An other note, Dotan: shouldn't $_HTTP_ACCEPT_LANGUAGE actually be
$_SERVER['HTTP_ACCEPT_LANGUAGE']?

My suggestion is:
$date = date('Y-m-t', strtotime('+2 months'));
$date = date('F jS Y', strtotime($date));
Only two lines of code, only four function calls. As you know, there are
many ways to do a thing.

You're relying on register_globals being on.
That's not going to work in 99% of the cases, it's a security issue.
Instead everything goes into the $_POST array:
echo $_POST['wim'] . "";
If the form action was "get" instead of "post" it would go into the
$_GET array.
You should also read up on sanitizing user input and sql injection.
http://www.phpsec.org/ has quite a few good links on the subject(s).

[PHP] Problem with EXEC and PASSTHRU
I am writing a php website for users to edit a global whitelist for Spam
Assassin - all is going fairly well considering I hadn't ever used php until
a couple of days ago. My problem is I need to restart AMAVISD-NEW after the
user saves the changes. I've acheived this using SUDO and giving the
www-data users the rights to SUDO amavisd-new. My problem is simply a user
friendlyness issue - below is the code I'm running -
if(isset($_POST["SAVE"]))
{
file_put_contents("/etc/spamassassin/whitelist.cf", $_SESSION[whitelist]);
$_SESSION[count]=0;
echo "Restarting the service.";
exec('sudo /usr/sbin/amavisd-new reload');
echo "Service was restarted.. Returning to the main page.";
sleep(4)
echo '';
}
The problem is that the Restarting the Service dialogue doesn't get
displayed until AFTER the Service Restarts even though it appears before the
shell_exec command. I've tried exec and passthru and its always the same - I
want it to display the "Service was restarted" - wait for 4 seconds and then
redirect to the main page. Instead nothing happens on screen for the browser
user until the service has restarted at which point they are returned to
index.php - its as if the exec and the sleep and the refresh to index.php
are all kind of running concurently.
Can someone PLEASE tell me what I'm doing wrong - or shed light on how I
should do this.

You're forgetting that the server, the browser, and anything between
may cache the data into chunks of any size.
Even if the browser /did/ receive the data "in real time" your code
would be wrong: you're ignoring the basic structure of a HTML
document, and any browser worth that label should ignore the meta
tag.
Do this instead:
// ...
file_put_contents("/etc/spamassassin/whitelist.cf", $_SESSION[whitelist]);
$_SESSION[count]=0;
exec('sudo /usr/sbin/amavisd-new reload');
?>
Service was restarted.. Returning to the main page.

www.php.net/flush may help you out, but there are many reasons for
even that not to work... such as IE needing at least 256 (out the top of
my head) bytes before showing anything, IE needing all data in a
before showing it and commonly to make sure you send at least some
20 characters or so before being able to flush() again.

You have to keep in mind that you are dealing with the difference in
speed between something that is taking place on the sever and something
that is being transmitted over a network. You don't make it clear
whether this is an in-house site or whether it is used by people at a
distance. If the latter, what you describe is not surprising at all.
I've never had a reason to look into how PHP sequences events when it
pumps out a web page, but it's not unusual for scripts in Perl, for
instance, to show delays in browser output when doing something on the
server. One consideration would be how long amavisd-new takes to reload.
I'm not very well-informed about hacking and security, but it would seem
to me that you are taking a risk by giving users root privileges to
restart amavisd-new.

Re: [PHP] PHP 5 Hosting
Hi, I wanted to give some feedback on PHP 5 hosting in case it helps someone. I signed up with DreamHost last Thursday. I also signed up with OCS Solutions to compare the two services. I also maintain a server with CalPop. When I signed up with Dreamhost, I discovered that you have to fill out a form and fax it to them, along with a rubbing of your credit card. Personally, I found that part rather annoying. They say it's for added security, but I've never had to do that with any other online transactions that I've done. OCS Solutions had me pay for a year up front, which always makes me nervous when checking out a new provider, but they do offer a money back guarantee. Actually, both providers offered a money back guarantee. DreamHost's is 97 days. That's pretty good. Cost-wise, both companies were fairly inexpensive. I ran a Google search for "DreamHost Coupon" and found a coupon that eliminated a majority of the up front cost. Actually, I was pretty surprised. They give you a free domain registration that includes private whois for free. After the coupon, I paid $9.90 and covered the start-up fee (normally $45), the first month of service, and the domain registration. It feels like I paid for a domain registration and got free hosting for a month. My account with DreamHost was created on Monday. Technically, it took 5 days to get my account set up. That's the longest set up delay I've ever experienced with any host provider. OCS Solutions called me an hour after signing up and had my account setup shortly thereafter. I also registered a domain when signing up with OCS Solutions. The whois was wrong. Somehow it ended up showing as registered to one of their employees, but I called and they quickly fixed it. The account was set up under the wrong username, but they fixed that quickly, along with problems with cpanel when it doesn't handle the name change correctly. Mistakes were made, but I was really pleased with how easy it was to get help and I was really happy with how much people obviously cared about helping out. After signing up with DreamHost, the domain that I'd registered with them wasn't working. I was exploring their control panel to figure out the problem when I came upon a DNS management page. The page automatically identified and fixed the problem. That was impressive. Also, I started exploring the DreamHost forums after signing up, something I almost wish I'd done beforehand. I found a lot of posts from very disgruntled customers. It sounds as if they've been running into problems lately on their servers. People complain A LOT about the lack of phone support from DreamHost... you have to submit a trouble ticket for everything. If your account subscription is high enough, they offer a limited number of call backs. The worst part was reading debates between the really happy and the really unhappy DreamHost clients. A lot of the discussions boiled down to verbal attacks between customers. I'm honestly surprised DreamHost didn't intervene. One last thing with OCS, the plan I started on turned out to be insufficient for my needs. I talked with them and they came up with a new plan that does everything I want and just charged me a little more to cover the difference. End result so far... CalPop: I've always had problems with the initial set up of servers at CalPop. Talking with their tech support on the phone is a nightmare; there's something wrong with their phone lines (seems like a really bad voice over IP solution). It usually takes way too many emails to resolve problems. I've also experienced a lot of hardware failures, which makes me wonder about the quality of parts they purchase. Once the server works though, everything seems to settle down until the next problem shows up. DreamHost: Best prices, low service. It seems like DreamHost is run by and tailored toward experienced techies. That's fine, I can work with that. I'm willing to try working with limited phone support. I'm really only concerned with delays I might experience when a problem shows up in something that's mission critical. Beyond that, there are a lot of features available here that aren't elsewhere. I'm getting great value for my money. OCS Solutions: Good prices, but you have to pay up front. Best customer service I've experienced from an ISP so far. I feel a lot more comfortable using them for anything mission critical. On Oct 11, 2006, at 10:12 PM, Kyle wrote: Hello, I would suggest dreamhost at www.dreamhost.com.

[PHP] How does the Zend engine behave?
Hi,
I'm using PHP 4.x and I'm trying to understand a bit about memory usage...
Firstly, when I say 'include files' below, I mean all forms, include,
require and the _once versions.
That said, when a script runs and it's made of several include files,
what happens?
Are the include files only compiled when execution hits them, or are all
include files compiled when the script is first compiled, which would
mean a cascade through all statically linked include files. By
statically linked files I mean ones like "include ('bob.php')" - i.e the
filename isn't in a variable.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded into
memory at the start of a request? (Of course those where the name is
variable can only be loaded once the name has been determined.) And when
are they loaded into memory? When the instruction pointer hits the
include? Or when the script is initially loaded?
Are included files ever unloaded? For instance if I had 3 include files
and no loops, once execution had passed from the first include file to
the second, the engine might be able to unload the first file. Or at
least the code, if not the data.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in
assuming that the uncompiled form is loaded? I.e the script is tokenized
for each request, and the compiled version is not loaded unless you have
engine level caching installed - e.g. MMCache or Zend Optimiser.
Fourthly, am I right in understanding that scripts do NOT share memory,
even for the portions that are simply instructions? That is, when the
second request arrives, the script is loaded again in full. (As opposed
to each request sharing the executed/compiled code, but holding data
separately.)
Fifthly, if a script takes 4MB, given point 4, does the webserver demand
8MB if it is simultaneously servicing 2 requests?
Lastly, are there differences in these behaviors for PHP4 and PHP5?
Many thanks,
Jeff

[PHP] Re: Problem with EXEC and PASSTHRU
Ok - This is a reply to ALL - Thanks for the great help - I now understand
why it wasn't displaying - it was all due to caching of data at the client
end before displaying in blocks. With some help in the comments of the php
manual for flush() I found a nice script that uses echo str_pad('',1024); to
help pad things out - also displays a little countdown to keep people amused
and convinced something is happening while the service restarts! I'm LOVING
php now - its a very simple language limited only by your imagination as to
how you use it! My knowledge seems to be lacking more in HTML and Browser
server relationships - I'm basing things on my background in Basic
programming as a kid - you do Print "Hello world" and it does that instantly
to the screen - little different with browsers!

Compiled when execution hits them. You can prove this by trying to
conditionally include a file with a syntax error: if (false)
include('script_with_syntax_error.php'); won't cause an error.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded

is variable can only be loaded once the name has been determined.) And

If your include file is actually included, it will use memory. If it is
not included because of some condition, then it won't use memory.
Are included files ever unloaded? For instance if I had 3 include
files and no loops, once execution had passed from the first include
file to the second, the engine might be able to unload the first file.
Or at least the code, if not the data.
If you define a global variable in an included file and don't unset it
anywhere, then it isn't automatically "unloaded", nor are function/class
definitions unloaded when execution is finished.
Once you include a file, it isn't unloaded later though - even included
files that have just executed statements (no definitions saved for
later) seem to eat a little memory once, but it's so minimal that you
wouldn't run into problems unless you were including many thousand
files. Including the same file again doesn't eat further memory. I
assume the eaten memory is for something to do with compilation or
caching in the ZE.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in
assuming that the uncompiled form is loaded? I.e the script is
tokenized for each request, and the compiled version is not loaded
unless you have engine level caching installed - e.g. MMCache or Zend
Optimiser.
I think that's correct. If you don't have an opcode cache, the script is
compiled again for every request, regardless of who requests it.
IMO, you're probably better off with PECL/APC or eAccelerator rather
than MMCache or Zend Optimizer. I use APC personally, and find it
exceptional -> rock solid + fast. (eAccelerator had a slight performance
edge for my app up until APC's most recent release, where APC now has a
significant edge.)
Fourthly, am I right in understanding that scripts do NOT share
memory, even for the portions that are simply instructions? That is,
when the second request arrives, the script is loaded again in full.
(As opposed to each request sharing the executed/compiled code, but

Yep, I think that's also correct.
Fifthly, if a script takes 4MB, given point 4, does the webserver
demand 8MB if it is simultaneously servicing 2 requests?
Yep. More usually with webserver/PHP overhead.
Lastly, are there differences in these behaviors for PHP4 and PHP5?
Significant differences between 4 and 5, but with regards to the above,
I think they're more or less the same.

I don't know for sure but chances are that mysql outputs errors on
stderr not stdout, so you need to redirect stderr to stdout for exec to

Can't say why you're not getting an error message, but when I have a valid
user, password, host, and sql in a .txt file, I get the last record from the
select statement I run output in the browser. Maybe start with getting it to
work with everything used correctly, then work backwards.

What you want is something like this:

if ( strstr( $_HTTP_ACCEPT_LANGUAGE, $language) ) {
print"You are from ".$valueArray[2]."!";

}
Your example is setting the variable $language to the array for each

Thanks, I see what I was missing.
So the first iteration,
$language is set to array("Afrikaans", "Afrikaans", "South Africa")
and the second iteration,
$language is set to array("Albanian", "Shqipe", "Albania")
That much I knew. Thanks, Chris.

Unless you're using an opcode cache, as I believe some of the are smarter
about that. Which and how, I don't know. :-)

[PHP] Job Opening
Well since the consensus seemed to be to allow job postings, I'll make one. :-) My company is looking for a few good PHP programmers. We are a Chicago-area web consulting firm developing web sites and web applications for a variety of clients, including several large academic institutions. We are looking for skilled PHP developers to join our team. (Sorry, that means yes, you'd have to work with me.) It's a small but growing company of less than 10 people, all fairly young and geeky. :-) Experience with PHP (although not necessarily prior work experience) is a must. If interested, contact me OFF-LIST for more information. Note: I am NOT in a hiring position, so do NOT send me your resume. :-) I'm just going to pass you on to the person who is. -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Now this is obviously just opinion since everyone is entitled to their own style, and while I might find it objectionable, I hardly represent the masses and their idiosyncrasies :) Now, the thing that I dislike about heredoc for such small strings is the switching between heredoc mode and the switching back. It's ugly on the scale of switching in and out of PHP tags. it would be less ugly if the closing delimiter didn't have to be at the beginning of it's own line in which case code could still maintain indentation formatting. Understandably it is not like this since it's flexibility lies in being able to place very versatile content within while not accidentally breaking out of heredoc context. To lighten the mess of heredoc I personally use the following format: blah blah blah blah blah blah blah blah blah blah blah blah $foo blah blah blah blah blah blah blah blah blah blah blah blah blah $fee blah blah blah blah blah blah blah blah blah blah blah blah blah _; ?> However that's only useful if indenting the content is not an issue. > From my perspective it's a single integrated > expression, cleaner, easier to read and proofread, and easier to > maintain than a concatenation of expression fragments strung together > with syntactical punctuation and quotation marks.

Am I unwittingly committing a > stylistic or logical faux pas? > > Conversely, what applications of heredoc do you find valid and valuable? My example also illustrates the kind of content I would be willing to contain within a heredoc... namely a large chunk of content, most likely with a mix of double quotes and variables. That said, I'm still more likely not to use heredoc... I think the one exception where I'm quite likely to use heredoc is when I'm declaring a javascript function from within a PHP function. > I ask because I use heredoc all the time, sometimes for inline code > as above but most often for template assembly, maintaining HTML in > external files that can be edited independently of the PHP logic. I use a tag based template system, there's no PHP in my content so my content files for the most part just look like more HTML. The templates are compiled to PHP (or raw content such as when creating stylesheets) after which they are used over and over without recompiling. here's an example of an email template: Hello , You or somebody posing as you has requested that your password be reset. If you did not request this email then you may disregard it and no changes will be made to your account. To continue please click on the link below and complete the form that will be presented. If clicking on the link does not open your browser then please copy and paste the address into a web browser to continue. http:///reset.php?rid= Sincerely, Admin Here's the code that invokes the template: getServiceRef( 'mail' ); $mail->addTo( $to ); $mail->setSubject( 'BlahBlah.com - Reset Password Request' ); $mail->setTemplate( '//emails/passwordResetDetails.php', $data ); $mail->send(); ?> Cheers, Rob. -- .. | InterJinn Application Framework - http://www.interjinn.com | :: | An application and templating framework for PHP.
