Dear all,
I am trying to pass variables from one php-file to another but that
doesn't seem to work. Anyone an idea what I am doing wrong?
The first file shows a dropdown with all the databases on the server
(only 1 for me). You have to select a database and put an SQL query in
the textarea.
Pushing "Execute query!" then calls the second file test2.php which
should put all the variables on the screen (first there was another
routine but that did not work, so I created this simple output to test
the veriables).
<html>
<head>
<title> PHP SQL Code Tester </title>
</head>
<body>
<!--query.php-->
<?php
$host="localhost";
$user="some_user";
$password="some password";
?>
<form action="test2.php" method=post>
Please select the database for the query:<br><br>
<select name=database size=1>
<?php
$wim = 5; /* this is added to test the passing of the variables -
doesn't work either */
$link = mysql_connect($host, $user, $password)
or die(" Cannot connect : " . mysql_error());
$db_table = mysql_list_dbs();
for ($i = 0; $i < mysql_num_rows($db_table); $i++) {
echo("<option>" . mysql_tablename($db_table, $i));
}
?>
</select>
Please input the SQL query to be executed:<br><br>
<textarea name=query cols=50 rows=10></textarea>
<br><br>
<input type=submit value="Execute query!">
</form>
</body>
</html>
This routine which is called with the routine above should print all
variables but it doesn't. Well, the routine itself works but the
variables are empty.

<head>
<title>PHP SQL code tester</title>
</head>

<?php

echo "$wim"; /* this is NOT printed to the screen */
echo "$host<br>"; /* only the <BR> is printed */
echo "$database<br>"; /* only the <BR> is printed */
echo "query: $query<br>"; /* only the <BR> is printed */
echo "Dit is test 2"; /* this is printed to the screen */

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'] . "<br/>";
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).

In the second script, the value of this will be in $_POST["database"].

$wim isn't part of your form - it will /not/ get saved into the next PHP
script. You can handle it through input type hidden elements in the
form, or through sessions, for example, depending on what you want to do
with it.

phpmyadmin has all the functionality you are trying to build - and it
implements it securely - even if you are writing the code/tool mentioned below
as a learning exercise (as opposed to writing it because you need to
be able to execute arbitrary queries easily) then the source of the
phpmyadmin project is a good resource.

... which will contain absolutely nothing, since you haven't provided any
value: <option>blabla</option> does not contain a value that can be sent
to the next page.
And, don't build the link to the database (and possibly spawn an error)
when you're right into your HTML and just printed <select> to the screen.
If the connection fails, the error will most likely not show up, you'll
have an empty select box, we'll get a new question from you etc.

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.........</A></P>";
exec('sudo /usr/sbin/amavisd-new reload');
echo "Service was restarted...... Returning to the main page.";
sleep(4)
echo '<meta http-equiv="refresh" content="0;URL=index.php">';
}
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.
Thanks,
Matt

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');
?>
<html>
<head>
<meta http-equiv="refresh" content="4;URL=index.php">
</head>
<body>
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
<TABLE> 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.

Thanks to all the suggestions I received on this issue.
I have tried running PHP as an Apache module. As Jochem mentioned, this
restricts the startup delay to just when Apache starts, not with each
request - which is a great improvement.
I have also set the various configuration options in the VirtualHost
directives so my requirement for separate php.ini files has been removed.
There is one remaining issue though - how to get my PHP scripts to run under
different usernames for each virtual host. I need my PHP scripts to run as
specfic users as they need to interact with the filesystem. I am using
suExec and have set the SuexecUserGroup directive for each virtual host, but
this isn't used as PHP is not called by CGI.
Any suggestions?
Thanks,
Edward

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

strstr() might not be the best solution.

I am using $HTTP_ACCEPT_LANGUAGE. I copied-pested

Ah, in that case using $HTTP_ACCEPT_LANGUAGE relies on the
register_globals setting, which is a security risk (and turned off by
default). Please read up on this, so you know what you're up against...

Yep, that's pretty much exactly what I do. I suspect there is a much
shorter, and more opaque but elegantly clever way of doing it, but
that basic methodology has been with me since the mid 80's :)

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.

Hello,
I would suggest dreamhost at www.dreamhost.com.
Their prices look a bit hefty at first but there are referral codes
all
over the internet and you can end up saving $97. Their plans have
tons
of bandwidth and space and I haven't had any trouble with it. But I
would suggest them highly, their service is quite impressive. And if
you don't like the PHP features they let you compile you own!
Good Luck with it!

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
