Hello, I was wondering how to write a DLL that I can use from
php_w32api.dll? I want to get the memory usage using this code:
###########################################################
dl("php_w32api.dll");
$api = new win32;
$api->definetype("MEMORYSTATUS {
long dwLength;
long dwMemoryLoad;
long dwTotalPhys;
long dwAvailPhys;
long dwTotalPageFile;
long dwAvailPageFile;
long dwTotalVirtual;
long dwAvailVirtual;
}");
$api->registerfunction("long GlobalMemoryStatus (MEMORYSTATUS &a) From
kernel32.dll");
$a=$api->InitType("MEMORYSTATUS");
$api->GlobalMemoryStatus($a);
print_r( $a); // Prints like [0] => Resource id #6
class MEMORYSTATUS
{
var $dwLength =0;
var $dwMemoryLoad=0;
var $dwTotalPhys=0;
var $dwAvailPhys=0;
var $dwTotalPageFile=0;
var $dwAvailPageFile=0;
var $dwTotalVirtual=0;
var $dwAvailVirtual=0;
}
$b=new MEMORYSTATUS;
$api->GlobalMemoryStatus($b);
print_r( $b);// Prints all of the names, but all values are 0

###########################################################

So I need another function to which I can pass $a and then get an int back
or something that PHP can hande... I got visual studio 6... I got cygwin as
well... I use Windows ME... Any help is appreciated...

Thanks in advance // DvDmanDT

attached mail follows:

Ok, I solved the problem by calling GlobalMemoryStatus() inside the DLL and
then using references to the PHP variables... Some things I noticed during
this playing:
- It seems like this code doesn't set the values of $a:
$a=$api->InitType("MEMORYSTATUS");
$api->GlobalMemoryStatus($a);
or php doesn't pass the object on next time, 'cause inside the DLL all
values of it was 0 when I passed it as arg... Could also possibly be the
fact that I didn't have any free memory, but that seems little wierd as I
tried more than one time...
- It crashed as soon as I passed 4 arguments or more... Could be my bad
coding though... But the same code worked with only two arguments... The
four arguments were "long &a1,long &a2,long &a3,long &a4" and inside the
function they were assigned values from my MEMORYSTATUS variable... Testing
two at a time worked like I said...

I was wondering, who is the coder(s) of this extension? Does anybody know?

I don't know how to get it to work, but doing

$t = preg_replace_callback( '#[('.$atag.')(=(.*))?](.*)[/1]#isU', 'nc', $s);

should at least get rid of the warning.

The best PHP editor I know is Zend Studio. This is a real good editor with
debugging, highlighting and very good code complete.

Please don't start this again. If you want arguments about editors just
read the old ones in the archives. It's highly unlikely that any useful
new arguments will be made if we start a new flamewar over it. :) Just
suggesting one or two editors you like is more useful.

I have tested quite a few editors since i came to php as notepad started to
p1ss me off after some time...
I have never really touched vi so cant say much about that but I think Zend
is pretty good (ill even dare say better) compared to the others(homesite,
phpedit,editplus etc)
you DO get only a 21 day trial...but you can make it a free version if you
want ;-p
Its a very good product and if you can afford it i think you should buy it
as a lot of work has gone into it and the developers deserve the $$.

Please note: I have NOTHING at all to do with ZEND (the company,site and its
software) dont bug me with arguements, this is just my opinion...my 2 cents.

HTH

Cheers,
-Ryan

Living on the edge is one thing. Biting the hand that feeds you is another.

As for the topic on hand, for Windows, I like UltraEdit, and for Linux I
use Quanta.

attached mail follows:

If you read what i originally wrote you will see that I recomend buying
zend, I didnt give directions/info to crack anything (as i dont know how to
crack in the first place), if you can afford it compared to all the editors
i have tried zend is the best.
Besides,did I say something that we all dont already know?

Back to the topic, I have not worked on Linux (locally) as yet so have not
tired any linux programs but for windows I still go with Zend instead of
UI....just a personal preference and i am sure there are some who will share
my preference and some who wont.

One thing that works well for me (editor aside) is creating a staging server
(staging.domain.com) and doing all edits there. Then when everything is just
the way you want it, I have a script that copies everything from the staging
site to the live site.

It prevents having to work on your live production site (which can sometimes
cause problems if your changes are right the first time) and it also lets
you work on larger projects over a few days and push everything live at once
without having to copy the files in question one-by-one.

Hi all,

So I was under the impression that an HTML form "SELECT MULTIPLE" item would
return an array with all of the selected items. This array can then be used
with any of the standard PHP array functions, yes?

I have 1 HTML page that seems to work fine... However, another page that is
nearly identical is failing - giving me the following error: "Wrong
datatype for second argument in call to in_array". When I look at the
variable, it seems to ONLY contain a string - the first item the user
selected.

The only difference I can see is that the working SELECT MULTIPLE has
numerical values, and the dysfunctional one uses string values - but the
values ARE enclosed in quotation-marks... so I don't know why they're not
POSTing properly as an array. Is this a known bug or issue? Any thoughts
or solutions?

Thanks a bunch, take care,

Its the littlest things that kill ya.... Thanks a ton!

As a side note, I definitely do NOT have the brackets on the working page -
so its an undefined "feature" (or bug) that numerical-value SELECT MULTIPLE
variables post as an array to PHP.

Take care, and thanks again!

Use mysql_escape_string().

$query = "insert into table (field) values ('$safe')";

How do you manually unserialize session data? Using unserialize() on
session data from a sessions table is not working for me.

I have modified the gc function of my MySQL session handler to save
data from expired session records to another table,
'sessions_saved'. I can get the session data out and into the
sessions_saved table okay, but i can't restore some of the saved
session variables i need for field values in the sessions_saved table.

In the code below, $sess_data['pid'] is always empty even though I
can see it and its value in the serialized session data. The $pid
value has already been set to a session value using:
session_start(); $_SESSION['pid'] = $pid

function mysql_sess_gc ($sess_maxlife)
{

(code here to query session table for expired sessions)

// loop thru expired sessions and save to 'sessions_saved' table:
while (list($sess_id,$data) = mysql_fetch_array($r))
{
$sess_data = unserialize($data);

$pid = $sess_data['pid'];
$sid = $sess_data['sid'];

//store sessions in saved_sessions table
$query = "INSERT INTO sessions_saved (id,pid,sid,data) VALUES
('$sess_id',$pid,$sid,$data)";

$result = mysql_query ($query, $mysql_sess_conn_id);
}

(...now delete expired sessions from sessions table)

I'm having a bit of a formatting issue, and I was wondering if someone
might have an idea on how to solve it. Basically what I have right now
is a script that opens and reads the content of an image directory, each
time the script is accessed it writes the contents out to a text file
for me. I then open that text file and read it's contents, I want to be
able to display thumbnail versions of the pictures, 3 per row and as
many rows as needed. Unfortunetly, all I can do right now is 1 per row,
this is where I need the help. Here's the code that displays images:

$dat="$_GET[gallery].dat";
$file=fopen($dat, 'r');
$contents = fread ($file, filesize ($dat));
fclose($file);
$img=explode("|",$contents);

print "<table width=50% cellpadding=0 cellspacing=3 border=0>";

foreach($img as $image) {
if($image) print "<tr><td><a href=$image><img src=\"$image\"
width=150 height=100></a></td></tr>";
}
print "</table>";

So how do I make this work so I can have three cells per table row and
it actaully show the proper picture?

TIA

Tom

Hi,

I'm setting up a simple tracking program for a website I'm working
on. Currently it records a visitors IP address, but I would like to be
able to do a DNS lookup of these IP addresses. Is this possible with PHP
and if so, how is it done? I've been looking through Google, and the very
few real results I've come across are large perl programs which make little
to no sense to me.

Any help would be greatly appreciated.

Thanks
-Tim

attached mail follows:

$_SERVER[REMOTE_HOST];

This will do a reverse lookup on their IP.

Hope it helps

Actually, this isn't true. $_SERVER['REMOTE_HOST'] will contain the
hostname of the client if and only if the web server has placed that
value there. Simply referring to the variable does not cause a lookup
to be done.

To do the lookup yourself, use gethostbyaddr():

http://www.php.net/gethostbyaddr

Hope this clarifies it a bit,

Having a bit of trouble with my forms returnin 1 in the form fields accept the data that was entered. I think its because of this line,

$output_fname = isset($HTTP_POST_VARS['fname']);

I have a command action handler also that works in the same script and it seems to work well, the only problem that Im having is passing back the error to the related filed that requires proper data. I started just passing back a generic message so that I could get the routine down, once I get that I will be able to do more.

Here is a snipit of my code.

Why is my script autopopulating a "1" in the field names and not the orginal
values ?
Is it something to do with this statement ?
$output_fname = isset($HTTP_POST_VARS['fname']);

Im declaring the var and using it in value field in my form. I know that I
missing something. Its returning true when value is entered or when its not
and placing a nice 1 in every field of my form.

Im thinking
$output_fname = isset($HTTP_POST_VARS['fname']) ? $HTTP_POST_VARS['fname']
is the answer and ive tried for several hours to fix it.

$output_fname = (isset($HTTP_POST_VARS['fname'])) ? $HTTP_POST_VARS['fname']
: '';

but the value WILL be set regardless... in this case i'd prefer:

if(isset($HTTP_POST_VARS['fname'])) { $output_fname =
$HTTP_POST_VARS['fname']; }

alternatively, I wrote a nice function to pluck out $_POST vars only if
they're set. you could easily modify it to do $HTTP_POST_VARS instead of
$_POST

Also I want to note. If sids are accessible via http_referer, there is
a way to execute php scripts on behalf of a user. For example, user
clicks a link to some php script which will grab sid from referer and
then outputs a html with redirect to another script (for example to
set a forwarding filter or etc). Since sid is right and also script
was called from user's PC, this is a quite bad thing, but
unfortunately this still exists on several web based e-mails. So, be
careful in using only session mechanisms provided by PHP. It's quite
insecure.

What you need is an encoder like Turck. It is an extension that stored
compiled PHP code in disk files that can be loaded later without the
need of the original sources.

Actually, to be more simple, for paypal paying customers, I would use

yes i know about that but then the whole basket/cart system is out of your

No, it's not working.

Does your Apache httpd.conf file load the PHP modules?

Try changing your tags from <? ... ?> to <?php ... ?>

Try a page that contains only this one line:

<?php phpinfo(); ?>

Good luck.
