(sounds like a teacher, huh?) While I don't have any references to back it up - my guess would be that Java may be seen as more versatile in general programming terms. A staggering number of enterprise level web applications are built with Java, add to that the possibility of writing Android apps with the same knowledge. Of course, there are many ways to make Android apps without Java - I've written a few myself with simple HTML and Flash Builder. I would say that, in general, the other teacher is incorrect speaking strictly in terms of web development. PHP has already won that crown many times over. That said, when I was in University, it was difficult to find a programming class that taught anything but Java - and that was 10yrs ago now. I chalked it up to the education bubble not being able to see what the rest of the world is actually doing. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] MySQL over TCP results on CLOSE_WAIT state in PHP 5.3.8
Hi, I have a MySQL server A, a server B with PHP 5.3.8 and a server C with PHP 5.3.3. I'm connecting to the MySQL server on A via TCP from B and C using an internal network. Server B and C use the same PHP application. There are also same PHP scripts that get data from the database and then calculate up to 30 minutes. I close all database connection before doing the calculation to save connections (and ports) using: $thread_id = mysqli_thread_id( $this->handle ); mysqli_kill( $this->handle, $thread_id ); mysqli_close( $this->handle ); During a review on our servers I discovered that server B has a lot of network connection in the state "CLOSE_WAIT". Server C running the same PHP application has not.

Re: [PHP] AJAX coding and Sesisons
I have done this quite a few times lately, you shouldn't worry. Just have your session_start() and login security on the pages that you access with javascript aswell, they will have the same security as any other page. The sessionID is used for all requests to the server from the webbrowser, also from within a page from javascript. Which again means that you can use your validation scheeme on theese files aswell. As a side note, if your on a page the user spends much time on, having some Ajax functionality accually works like a little heartbeat / pulse, resetting the session time so that the user infact can spend more time on the same webpage without having to do some movement, :D regards, Kim Steinhaug - - - - - - - www.steinhaug.com - Original Message - From: "Bret Walker" <[EMAIL PROTECTED]> To: "PHP-Users" Cc: "Ivan Meyers" <[EMAIL PROTECTED]> Sent: Monday, August 22, 2005 9:57 PM Subject: [PHP] AJAX coding and Sesisons > I'm authoring a web app, and I want to use some AJAX functionality. > > The users log in via PHP, and they are verified page to page by a > session variable (which stores their username). > > I want to write some PHP that alters a database, but I want to be sure > that only authorized users can access the page, and that they can only > delete items associated with their username (in the table). > > I want to have javascript asynchronously call the php page, but I don't > know how to protect this page.

Re: [PHP] session_start(), Pragma and Cache-control headers
I solved the problem after a while, seems it had been
reacently debated in the bug pages within php, to remove
headers which are added by the session_start(); you can
add the following :
ini_set('session.use_cookies', false);
session_cache_limiter('');

[PHP] session_start(), Pragma and Cache-control headers
Hello,
I'm working on a downbload script which serves M3U
files (Winamp playlist files) through a PHP file
like this :
somepath/download.m3u.php?id=2
Then in the PHP script I generate the M3U file, and
serve up the headers I want. Swell so far, but a
little problem appears.
The downloads are for members only, and therefor I
need to check if the user is logged in, I do this by
sessions and therefore I add a session_start() at the
start of my file. When I do this some headers are
added to the file, namely :
Set-Cookie: PHPSESSID=xxx; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0
Pragma: no-cache
Theese headers are not needed, and I dont want them
either, exept I cant seem to get rid of them since I
need the session_start() in the beginning of the file.
Sure, I could wish for a function unset_potensial_header(pragma);
I guess there are no way to remove theese unwanted headers?
Yesterday I had to give up another problem, but luckily I
found the answer here : http://bugs.php.net/bug.php?id=33057
So to sum it up :
How can I remove the Cache-Control and Pragma headers?
And Im not looking for this answer :
header('Pragma: ');
header('Cache-control: ');
The headers are still sendt, exept they are empty, doesnt look
like a nice sollution for a production environment.
Kind regards,
Kim Steinhaug

Thanks for responding. I found out what the problem was. There was an

for your help, I really appreciate it. :)

It's telling you that $data['0'], which is used twice in your query, is not
a valid index (ie. it doesn't exist) for the $data array.
Why don't you dump the $data array after it is set to see where the problem
is:
$data = $this->get_cat_coord($child);
print_r($data);
die();
Take a look at what comprises the $data array and you should find your
problem.

Thanks to all of you for your explanation of my method. Minuk, thanks for
the detailed explanation, it really helps me understand what I'm doing
wrong.
Now I have one more problem. When the $children array is empty, it returns a
10 instead of a 0. Why is that? Here's the method again with the recommended
improvements you guys provided:
function get_children($parent) {
// FORMULA: rgt value of first child + 1 = left value of second
child
// check rgt value of parent against each child (rgt + 1).
// If rgt valueof child plus 1 equals rgt value of parent
then
// that child is the last child of the parent.
$parent_coord = tree::get_item_coord($parent);
$descendants = $this->get_descendants($parent);
$children = array();
for ($i = 0; $i < count($descendants); $i++) {
if ((empty($children)) && (($parent_coord['0']['lft'] + 1) ==
$descendants[$i]['lft'])) {
$children[] = $descendants[$i]; // found first child
}
elseif (($children[count($children)-1]['rgt'] + 1 ==
$descendants[$i]['lft']) && $children[count($children)-1]['rgt'] + 1 !=

I can tell you from a quick glance that you have the following case
function X()

Have you tried giving $children an initial value, such as

{
$children = array();
if ()
{
$children[]=...
}
elseif ()
{
$children[]=...
}
if (count($children)>0)
return $children;
return 0;
}
I may be getting a head of myself, but the
$children[]=...
line adds the $descendants into the ARRAY variable, $children. Unless I'm
wrong, you MUST declare $children as an ARRAY FIRST(see first line of the
function, "$children=array();")
Secondly, if you want the function to return 0 if no $descendant entries are
added to $children, you must check to see if the $children ARRAY is EMPTY.
if (count($children)>0)
return $children;
that line basically says if ARRAY variable $children has more than 0
elements, return that ARRAY.
Finally,
return 0;
if the ARRAY variable $children has 0 elements(count($children) returns the
number of elements in ARRAY variable, $children), "return $children" is NOT
executed. The next line is "return 0".
This is a lazy way of writing the following :
if (count($children)>0)
return $children;
else
return 0;
If it seems like I'm explaining too much, it's because from the code

[PHP] Host for Mod PHP5
Hello everyone, I know this is going to be tough but I need a hosting company that supports PHP5, has unlimited disk space and a good amount of bandwidth with a decently fast connection for a decent price. I realize that this might be rare, but is anyone offering such a package like this anywhere? My client doesn't want a dedicated server because it costs too much for him at the moment. He wants to build a music website where people can download free music from. The music is recorded by him and he has artists that are eager to get their music out there into the public. Any suggestions on a temporary shared hosting company for him? Any help would be appreciated. Nilaab
RE: [PHP] Help With PEAR::DB Connection
Jim,
Thank you. Problem solved thanks to you. The moment you said that PEAR::DB
is not finding the MySQL extention I realized that the extension in php.ini
hasn't been commented out and the extension folder had not been recognized
by PHP. I forgot we had to do that in PHP5. Everything is working like a
charm now. I really appreciate your time and concern.
Nilaab
P.S. -- And sorry, I'm using Windows XP as the development environment and
Linux as the server. The Windows OS is where I was having the problem.
Thanks again...

The message 'extension not found' means that PEAR couldn't find the mysql db
extension. Hmm. In cases like this, create a phpinfo.php file as documented
on
this list and see what shows up. Or, you can type at the command prompt: php
-i, then look for the MySQL extension in the output.
Also, you neglected to tell us what OS you are running, etc.

[PHP] For Loop Problems
Hello Everyone,
I'm building a hotel management system and I can't seem to figure out why my
for() loop doesn't work the way it should. I'm using patTemplate to create
the HTML Template (I like using it and I don't want to start a pro/con
template war). Here is the script:
for ($j = 0; $j < 32; $j++) {
for ($i = 0; $i < count($num_days); $i++) {
$template->addVar("room_num", "ROOM_NUM", '101');
$template->addVar("room_type", "ROOM_TYPE", 'NQQ');
$template->addVar("guest_NameRate", "GUEST_NAME", 'NAVID YAR');
$template->addVar("guest_NameRate", "GUEST_ID", 'fname');
$template->addVar("guest_NameRate", "CLASS_GUEST", 'fname');
$template->addVar("guest_NameRate", "ROOM_RATE", '49.95');
$template->parseTemplate("guest_NameRate", "a");
}
$template->parseTemplate("guest_row", "a");
}
This inner for() loop works great. It creates a SINGLE row with 7 columns of
data (one column for each day of the week). However, the outer for() loop
does not work like it should. I want it to display 32 rows of 7 columns per
row. But what happens is that on every row after the first row it appends 7
more columns at the end of each row. So row 2 will have 14 columns, row 3
will have 21 columns, row 4 will have 28 columns, and so on. I can't figure
out why this is. Either it's something new in PHP5 or I'm doing something
really stupid. I am sending a PDF attachment of a snapshot showing a hint,
made purely with HTML, of what I am trying to achieve. If anyone can help me
it would be greatly appreciated. Thanks guys.

RE: [PHP] what is difference between php and perl
PHP is more of a "binding" language that takes advantage of many different coding practices and puts them together. PHP is not jealous and does not separate or shun itself from other languages and borrows many of the ideas, schemes, similar libraries, etc. from these other languages. And yet, it is completely unique in its own way. Its easy-to-learn, low-cost and cross-platform identity has made it very popular in recent years. Perl is a great but is more of a mature language that has been around for the longest time and it doesn't have the same flexibility as PHP does on the web. You will find that PHP will far out-pace Perl coding, saving you both time and money. PHP works concurrently with free solution components such as Linux OS, Apache Web Server, MySQL Database and others (LAMP - Linux-Apache-MySQL-PHP). These components all work together beautifully, yielding fast and stable applications. Invest some time into it and see what we mean. -Original Message- From: Syed Ghouse [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 21, 2004 2:06 AM To: php mailinglists Subject: [PHP] what is difference between php and perl Hi all will anybody tell me the difference between perl and php Regards Syed -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi
I know this not what you asked and please feel free to tell me to mind
my own business, but a more useful design for your DB would be something
like this:
Table : rooms
Fields: room_number (PK), room_type
Table: Customers
Fields: customer_id (PK, autoincrement), first_name, last_name, etc, etc
Table: bookings
Fields: room_number, booking_date, customer_id - PK(room_number, date)
In the short term, changing your db will be a bit of a pain cos of the
code rework, but the db design will be more scalable and more useful in
the long run. To get the display that you required you can do something
like this - assuming that you want a seven day span starting from today
(for example) - showing only the first two days
$query = SELECT a.room_number, a.room_type, IFNULL(CONCAT_WS(" ",
b.first_name, b.last_name), "Empty Room"), d.room_number, d.room_type,
IFNULL(CONCAT_WS(" ", e.first_name, e.last_name), "Empty Room")
FROM rooms a LEFT JOIN bookings c ON a.room_number = c.room_number AND
c.booking_date = "2004-07-09", customers b, rooms d LEFT JOIN bookings f
ON d.room_number = f.room_number AND f.booking_date = "2004-07-10",
customers e
WHERE b.customer_id = c.customer_id AND e.customer_id = f.customer_id
You will still have to add more code for the other five days, but if you
want to be really clever and save wear and tear on your keyboard you can
build the query dynamically using a loop...
You don't have to use a query this complicated, but if you do, you shift
the bulk of the data processing and arranging to the DB (which does it a
lot more efficiently than PHP). Then you just have to use PHP to create
the table, the relevant headings and to populate the cells.
Ok, I am finished sticking my oar in...

Chris,
It's a little difficult to do in ascii, but here's an attempt. This is a
simple hotel/motel log of who's staying in certain rooms. The 7 columns are
the 7 days in the week and guest names fall under whichever date they
checked in. So, let's see if I can give you a visual representation of this.
I will only include two columns and a few rows, for now. You may have to fix

it looks like you need to set up your loops the other way around.
right now your code is like this:
for (columns)
{
for (rows)
{
}
}
you want:
for (rows)
{
for (columns)
{
}
}
explained in english: you need to handle one row/person at a time and
not one column/date at a time.
on the other hand i'm not sure i totally understand your desired
output, so maybe a quick ascii table would help me/us?

[PHP] Creating Rows and Columns Using for() Loops
Hello Everyone,
I have an HTML table with 7 columns and 32 rows, not including table headers
and footers. I want to create a tabular data table that spans 7 columns and
32 rows. I get my info from MySQL and use for() loops to loop through two
types of arrays. An array containing the dates (the columns) and a table
containing first and last names. The names will go underneath whichever date
it is associated with, with a maximum of 32 names per column (hence the 32
rows). I am using patTemplate to create the table. Here is what I have so
far:
for ($i = 0; $i < count($num_days); $i++) {
$template->addVar("date_column", "DAY", $num_days[$i]['day_text']);
$template->addVar("date_column", "DATE", $num_days[$i]['month_text'].'
'.$num_days[$i]['date']);
$template->parseTemplate("date_column", "a");
$template->addVar("sort_row", "SORT_FNAME", 'fname');
$template->addVar("sort_row", "SORT_LNAME", 'lname');
$template->addVar("sort_row", "SORT_RATE", 'rate');
$template->parseTemplate("sort_row", "a");
for ($j = 0; $j < 32; $j++) {
$template->addVar("guest_NameRate", "GUEST_NAME", 'BOB RICHIE');
$template->addVar("guest_NameRate", "GUEST_ID", 'fname');
$template->addVar("guest_NameRate", "CLASS_GUEST", 'fname');
$template->addVar("guest_NameRate", "ROOM_RATE", '49.95');
}
$template->parseTemplate("guest_NameRate", "a");
$template->addVar("room_num", "ROOM_NUM", '101');
$template->addVar("room_type", "ROOM_TYPE", 'NQQ');
$template->parseTemplate("guest_row", "a");
}
I populated the guest's name statically so I can see how the loop works. The
looping is wrong and it only yields 7 rows. In the first row it has 1 column
of data, the second row has two columns of data, the third one has three
columns of data, and so on. How do I fix it to where each date column has
exactly 32 rows of guest names?
I hope this makes sense. Any help will be appreciated.

[PHP] Session Question
Hi All, I have a question about sessions. I need to pass session data from one domain to a secure domain. (www.mydomain.com to www.securedomain.com). I would like to preserve the session data in case the visitor goes back to www.mydomain.com. I thought about just passing the session ID to www.securedomain.com, but if I need to destroy the session while the visitor is in www.securedomain.com, I am hoping this will also include destroying data from www.mydomain.com. Basically, I am talking about a shopping cart system. If the user decides to stop half way through the checkout on the secure site and continue shopping in the store, I want the cart to remain. But if the user completes the checkout process on the secure domain, their cart should be empty when going back to the original domain. Thanks for any help.

Hi,
This is more of a Javascript question so please forgive.
I generate a dynamic form with php.
I need to be able to test in javascript if a certain field exists:
.
.
if (document.myform.mytextfield) {

.
This line will give me the javascript error "document.myform.mytextfield is undefined"
If it does exist, then it works fine.
So how do I test if a field exists without getting an error?
Thanks for any help.

Re: [PHP] How printing the name and value of a variable ?
Why?
echo "THE VARIABLE ".(please help me right here)." EQUALS ".$tigidizougou;
Obviously the variables name is tigidizougou, so just do this:
echo "THE VARIABLE tigidizougou EQUALS ".$tigidizougou;
Or am I missing something here?

Re: [PHP] Form Question
Thanks, but same problem.
alert() will give me the correct values, but it is still not unchecking the
boxes.
Strange, it obviously sees them as the statement
if (document.LevelListForm.elements['rgItems[]'][i].checked == true)
is correctly found for every checked box, but it just can't seem to find
them to uncheck them.
And I don't get any javascript errors.

Re: [PHP] PHP - Internal linking in a page
Your get statement is wrong: http://maloyportalen.no/~critical/maloy/index.php?page=main2.php?id=7 use http://maloyportalen.no/~critical/maloy/index.php?page=main2.php&id=7 You only get 1 question mark, any after will be treated as part of the variable page.

[PHP] Form Question
Hi,
I am hopeing someone can help me with this.
This is more of a javascript problem I suppose.
I have a bunch of check boxes on a from that I have given a name of rgItems[] so I can
access them as an array in php.
But I can't find a way to clear all the checkboxes on the form at once. a reset button
only resets the form to the original values, but I need to be able to clear all the
check boxes.
<!--
function ClearLevelListForm()
{
for (var i=0;i<document.LevelListForm.elements.length;i++)
{
if (document.LevelListForm.elements[i].checked == true)
{
alert(document.LevelListForm.elements[i].value);
document.LevelListForm.elements[i].checked = false;
}
}
}
//-->
I do get the correct alerts from the above script corresponding to the number of
checked boxes, however, the second line does not seem to be unchecking the boxes. I am
not sure if this has something to do with the fact that all the boxes have the same
name rgItems[] and the browser doesn't know which one to uncheck.
Has anybody else come accross this?
Thanks,

may have had the same problem when name mutliple form elements using the array style:

[PHP] Re: Dazed and Confused
I think the fog is starting to clear, thanks for the help.
I do have one more question:
If I want to use array_walk in a class, how do I refer to a function in that
class?
Class MyClass
{
.
.
.
function DoArrayStuff(&$item1, $key, $nMode)
{
echo $item1;
}
function SomeOtherFunction
{
.
.
$myarray already filled with, say, 5 items;
array_walk($myarray,'DoArrayStuff',1); <--- PHP error:
DoArrayStuff() - function does not exist in . . .
I have tried 'MyClass::DoArrayStuff', 'this->DoArrayStuff',
'$this->DoArrayStuff' but none work.
The only way I can seem to use DoArraySuff is to define the funcion
seperate(outside) from the class, which seems kind of odd since the only
time the function is needed is internally by this class.

Re: [PHP] Dazed and Confused
So are you saying there really is no array pointer?
Lets say I have an array with several different values like:
$myarray["a"] = "s";
$myarray[3] = "d";
$myarray["sdf"] = "y";
There is no way of saying give me the value in the array at position 2?
Since the size of the array is returned as 3, should there not be a way of
doing this?
Like I said, I seem to be blanking on arrays.

[PHP] Dazed and Confused
For some reason my brain is not operating within normal parameters this week.
$myarray["test"] = "sd";
echo $myarray[0];
Why will nothing echo? Do I somehow have to initialize indexing on the array $myarray?
php says that $myarray is an array, but I can't access it with numeric indexes.
I know if I do this:
$myarray = array("test"=>"sd");
that I can now echo $myarray[0] and get the value of sd returned.
Re: [PHP] Array Question
No, array_keys does not do what I want, in order to user array_keys, it assumes I know the value of the key, but I don't, I want to get the value of the key but all I know is the index. > Perhaps you want to look at array_keys(). > > On Monday, October 28, 2002, at 05:48 PM, PHP List wrote: > > > How can I get the name of the index? > -- > Brent Baisley > Systems Architect > Landover Associates, Inc. > Search & Advisory Services for Advanced Technology Environments > p: 212.759.6400/800.759.0577 > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Array Question
This doesn't seem to work for anything past the first key:

None of these give me anything:

[PHP] To store or not to store . . .
Hi, I was wondering about the following: Should I store a picture directly in a MySQL table? Or just store the link to a file on the system somewhere? I would think that leaving the picture as an actual file and just storing the link would be quicker. But what are the dis/advantages of storing right in the table? I like the idea of not cluttering up my file system. Pictures would only be about in the 20K range.

If you don't know how it's setup, I'm guessing it's not a loadable module and you will need to recompile apache.

[PHP] Sessions and Classes
What is the proper way to transfer class properties through-out my pages...
let's say i have a ShoppingCart Class and i have methods like
addToCart(id, qty) and deleteFromCart(id)
also i have properties like CartItems("id" => array(), "qty"=> array())
this is what i do...
//when the user enters my site, i do some...
-
if (!session_is_registered("myCart")){
$myCart = new ShoppingCart();
(some other stuffs...)
session_register("myCart");
}
else {
$myCart = new ShoppingCart();
}
--
if the object in the session is not present
i would create an instance and then register
it to the session.
else if it is present, i would just reconstruct it...
because if i don't, even though it is in the
sessions, the properties and methods are
not constructed (no handler, i don't know how
to call it).
my code works, but is there any other way
to do this, because i think it's kinda slow
another question, is it ok to have a database-driven
shopping cart? i make use of the database to as the
actual cart holder?
i need your opinions on these

Re: [PHP] printing html
You could just change the code for the generated page to re-generate the
page without the headers, etc. Then just link to the same page with a print
command:
echo "Click here for a printable version of
this page.";
if ($print <> "yes")
include("header.inc");
Something like that anyways.

Re: [PHP] Images
Thanks, but my html is valid, and what you are doing is not what I want to
do.
I want to display a random image included in the page, just like a banner
program would work.
I do not allow php execution on the page so the only way to get the image is
to call the script with the img src tag, just like a banner program would.

Re: [PHP] Engine Question
Thanks, The manual doesn't really make it clear though, all it says is: This sets the value of the specified variable. php_flag name on|off And then it later it says: engine boolean This directive is really only useful in the Apache module version of PHP. It is used by sites that would like to turn PHP parsing on and off on a per-directory or per-virtual server basis. By putting engine off in the appropriate places in the httpd.conf file, PHP can be enabled or disabled.

Re: SV: [PHP] Sending alots of mail
Thats interesting.
I tried to do the same thing with 5000 emails using sendmail, and I found
that only about 1/2 were actually sent, it seems like the multiple calls to
mail caused some of them to be ignored. I had to sleep for a couple of
seconds before each call to mail() in order to get them all out.
No one else had this problem?

Re: [PHP] Need open source community help!
IMO I would have to say it depends on the Timeline of your Boss. Releasing the app to the open source community would be great, the more there is, the more reason for people to stop using MS, but you can't demand a schedule of when new features will be added. You may have to go with the MS for now, and wait for your app to be developed with the new features, then convince your boss on moving to your software. You should be able to move all the data from one to the other without to much trouble.

[PHP] Engine help
Hi, I am trying to upgrade from php3 to php4, I recompiled apache_1.3.20 and php4.0.6 as per instructions(http://www.php.net/manual/en/install.apache.php). Everything seemed ok, but LoadModule in the httpd.conf was no longer recognized so I # all the LoadModule and AddModule lines. httpd -l shows mod_php4.c in the list. However, I was using this before: php3_engine on What do I use now? I tried just engine on, but httpd complains: Invalid command 'engine', perhaps mis-spelled or defined by a module not included in the server configuration Thanks for any help.
Re: [PHP] Loop error?
Oops, well, that is just mental.
Must be getting tired or something, yes, that's it :)
Thanks.

[PHP] Loop error?
Hi,
Can anyone tell me why this is a never ending loop?
$i=0;
$count = 1;
while ($count > $i);
{
echo "$i ";
$i++;
}

[PHP] mysql table dump problem
Hi list, I have scoured the archives with no good game plans. Here is what I am trying to accomplish: dump a table to a file on my server: $sql = "SELECT * INTO OUTFILE '/tmp/test.txt' FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n' FROM table_name"; take the file and email it to someone: using a mime-mail class from http://phpclasses.upperdesign.com The above works perfectly. I am able to create the file and email it to a designated address. Problem is that once I have created the dump file, it will not allow me to overwrite it and it gives me an error. Error = rm: cannot unlink `test.txt': Operation not permitted. It is owned by mysql:mysql. So it looks like it must be deleted by root or I need to change the ownership of the file so it can be deleted. So... What is the best way to remove the file before re-dumping it to the /tmp directory? I'm not sure if it is possible to switch to root...but I know that is probably a very bad idea. How can I change the ownership of the file so it can be deleted from PHP code? TIA, Scott P.S.
