[PHP] PHP and DOM XML
I have one question about operations that can be done with XML. What I need to do is build a web site which stores some data in XML files and retrieve that data.

[PHP] Session with or not cookies
Hello, I'm working with sessions. It's work fine with PHP 4.0.6 and when I update to 4.1.2.

This work fine But now, with no cookie enabled, the PHPSESSID was not add in the end of the URL. So I loose the session and the session variable. It is a change in this new version ?

Re: [PHP] strip spaces from inside string
the easiest way would be: ? // - // init var $str = ; $str = abc def ghi; $str = str_replace ( , , $str); echo $str.br; // // output: // abcdefghi // // // or a regex: $str = abc def ghi; $str = ereg_replace( , , $str); echo $str.br; //if you want to strip any whitespace character: $str = abc def ghi; $str = preg_replace(/\s/, , $str); echo $str.br; // - ? preg_replace is quite powerful, so if you only want to strip some spaces, you should prefer str_replace.

On the page you start the session,
${session_name()} isn't set. so if you need that on the first page too, you
should do the following
?php
session_start();
if (!isset(${session_name()})) {
${session_name()} = session_id();

On 4/4/02 5:19 PM this was written:
If you made your link like this: a href=filename.php??=sid? it

on the name plus the session id. If cookies are enabled you will only see
the session id passed through the url on the first page.. After that you
wont, thus the little script I wrote so the '?' doesn¹t show up. Now if
cookies arent enabled you will see the session name and id passed through
the url every single time. There is absolutely no reason to use those

You could lock the xml file while a user registers:
http://www.php.net/manual/en/function.flock.php
if ($fp = fopen($file, r)) {
if (flock ($fp, LOCK_EX + LOCK_NB )) {
// process registration here
flock ($fp,LOCK_UN);
fclose($fp);
}
}
however only one user will be able to register at a time.
It would be better to store this in a database because then you can have
multiple simultaneous registrations. Then when whatever application needs to
see the info as xml, have php generate the xml from the data in the
database.

Hi Sebastian! Lately I have noticed many scripts that all consist of one file even though they create the appearance of many pages. For example, you would open setup.php and a form would appear. Then after you complete the form a new page appears with the results of your form, however the URL is still setup.php. So basically you can make complicated forms span only one file instead of having separate file to gather, display and save the data, how is this done? You can handle the HTML-output from within any functions. What I am doing normally is the following. I got one page, let's say main.php When calling this page I pass it a variable that tells main.php which function to execute (printForm, submitForm, changeDB etc.) This is done by a simple switch-cascade. Now I'm organizing my functions properly in different include-files, let's say displayFuncs.php, dbFuncs.php etc.. And IMHO anything is much more clean and relaxed like this ;) On the other hand, if you connect to a db etc. you only have to write the code for the db_connect only one time (I include this, too).

Sounds like you might be trying to do things the hard way. Wouldn't it be easier to simply set the table widths as a percentage rather than an exact width in pixels?

[PHP] Cannot compile my extension as a shared .so library
Hi php-4.1.2 linux RH 7.2 I have created a small php extension. The extension works as expected when I compile it using $ ./configure --with-foo make # foo is the extension It gets compiled into the php binary. All is well, but I would like to compile my extension as a loadable modules (ie to use with the dl() function). Thus $ ./configure --with-foo=shared make The compilation completes with no errors. The php binary works (my foo ext is not included in the binary), but I end up with *no* 'foo.so' file. Instead I get this $ ls -l modules/ 51776 Apr 5 13:11 foo.a 647 Apr 5 13:11 foo.la I expected to see a 'foo.so' file. Obviously I cannot use dl() on these files.

RE: [PHP] mysql_fetch_array()
Jason,
This is for an events calendar, I want all the dates form the db but when I
am generating the individual days for the calendar I need to know whether
there is an event for that day, hence pulling out all the dates from the db.
As I am looping through all the days in a month to dynamically create the
calendar, I do not want to loop through the entire recordset to look for a
date for that day in each iteration. Does your method find any row in the
recordset with a given date?
I am at present exploring the possibility of creating individual arrays for
each row in the recordset using the date as the name of the array, then
testing to see if it exists. That way I can check for the existence of a
given date at any point in my code and reference the associated values
without looping through the recordset each time. My code is as follows...
while ($row = mysql_fetch_assoc($events)) {
$a = date_ . $row[event_date];
$$a = array($row[event_id], $row[event_title]);
}
if ($date_2002-04-15) { do_something(); }
Any comments will be greatfully received.

$events = mysql_fetch_array($recordset);
this drags in 3 columns from my table...
event_id, event_title, event_date
I want to search the recordset for a given date, if found I
want to be able
to reference event_id event_title from the row. I am using PHP 4.01.
Shouldn't you be doing your searching and selecting from within
your mysql
query?
But if you insist on doing it in PHP then:
if ($events['event_date'] == whatever) {
do_something();
}

[PHP] multiple php.ini files
hi, does anybody have some experience with running PHP with different permissions and modules. The only way that I imagine is to have 2 (or more) independent PHP installations with separate php.ini files. But this is stone age technique... I am sure that PHP has some kind of ini loading functionality (that I could not found in the documentation) Thank you very much for in advance for any creative suggestion.

RE: [PHP] Includes
Well, I think I should give a better explanation. I have been
seeing a lot
of scripts that appear to be on multiple pages. For example:
You open file.php, and you are greeted with a form asking
your name. You
give in your name and then submit the form. After you submit
the form you
would normally get a new page saying your name has been
stored or something
like that. This time, that also happens BUT you do not go to
a new separate
file. The URL in your browser is still on file.php, however
the form that
was there before is GONE and you see a totally new page. I am
asking how
something like this can be done. If it will help I can attach
a file that
does this.
Yes, and exactly this is what I told you ;)
I've got one page, let's say main.php.
This page is looking for a var, let's say called $curAction;
$curAction is not present the script knows that you're new to
this site and calls a function called displayWelcome (wherever
this function is defined ;)).
?php
$curAction = $HTTP_POST_VARS[curAction];
switch ($curAction)
{
case displayForm1:
{
displayForm1();
break;
}
case displayForm2:
{
displayForm2();
break;
}
case logoff:
{
displayGoodbye();
logout();
break;
}
// And so on...
}
function displayForm1()
{
?form!-- html goes here --/form?php
}
// ...and so forth
?
So this switch casecade handles what content is to be displayed,
which looks as if you where getting different pages...
Better now?
Cheers,
Kiko

Re: [PHP] Re: preventing back button usage?
i don't like javascript. It's pain in the ass to get this working on more than IE and Netscape. Btw, to get it working on IE and Netscape is annoying enough already imo.So what i would do is registering some sort of variable in the session, that shows you if the page has been submitted already. On the page that processes the form, you register this variable to the session, if it isn't registered already. if it is registered already, you simply ignore the request That's the easiest way, but as long as the session remains, the user wouldn't be able to submit this form again. So if you want the user to be able to submit this form again but preventing him from submitting the same data again, you have to do a little more than what i mentioned above.

[PHP] Session Freakiness. Losing Session.
Hi, I have an odd problem. I have intermittent loss of sessions happening, and I've spent lots of time trying to figure it out, but I am at a loss here. I found a post on phpbuilder that seem to be the same or a similar problem from 2001: http://www.phpbuilder.com/forum/archives/2/2001/3/1/125803 Unfortunately no conclusion seems to have been reached in the thread. Anyway, to my problem. I set a cookie with the sessionid on successful login. I also store the sessionid in a mysql database with a timestamp. I check the cookie with the db, and update on each reload. The script resides in one page, that is used repeatedly, and uses the same sessionhandling function for each request. I have the timeouts set to 1 hour (3600) for both the sessioncookie, and the session file on the server. Php version is 4.1.2, residing on Gentoo Linux, with a mysql db. I have observed the directory containing the sessionfiles, while a tester browsed the site, and watched the session disappear from the directory before timeout has elapsed. It is an intermittent problem, and seem to happen randomly... Any ideas what's going on here? Any hints would be greatly appreciated!

Miguel, Thanks for the reply. . MySQL has a command-line tool called 'mysqldump' which will output a text file containing all the table creates and inserts necessary to recreate the database. O.K. Now I have a .txt file of my sql statement. .. As others have suggested, you can use phpmyadmin to import this file, or you can just pipe it into the mysql command-line tool on the server once you've created your database. Look inside the file created by mysqldump and all will be much clearer. I take that to mean (the ISP's remote server where my website resides). Right? How can I get the compete mysql statement onto the ISP's server? Please advise. What I would like to know is: I would like to find out the steps one takes in going from the process of having the mysql data reside on my harddrive - localhost - in development - to my ISP's server when it goes live. The site resides on a remote server (the ISP's) when it is published (or goes live). Thank you. Tony Ritter

Jason,
This is for an events calendar, I want all the dates form the db but when I
am generating the individual days for the calendar I need to know whether
there is an event for that day, hence pulling out all the dates from the db.
As I am looping through all the days in a month to dynamically create the
calendar, I do not want to loop through the entire recordset to look for a
date for that day in each iteration. Does your method find any row in the
recordset with a given date?
As I understand your problem, I would suggest, that you just select the days
in the month, where there are events
f.e. select count(ref#) from DB where date 'inside your scope' and events
'are there events'
this gives you the number of lines.
If there are any, you could ask more detailed, using the informations stored.
If there are no events, make the calendar as normal.
Thats also a good explanation for the column ref# (autoincrement, unique)
Even you only have to deal with one select, and can order your result, so
that it makes
you no pain showing them
I am at present exploring the possibility of creating individual arrays for
each row in the recordset using the date as the name of the array, then
testing to see if it exists. That way I can check for the existence of a
given date at any point in my code and reference the associated values
without looping through the recordset each time. My code is as follows...
while ($row = mysql_fetch_assoc($events)) {
$a = date_ . $row[event_date];
$$a = array($row[event_id], $row[event_title]);
}
Here the select could be
Assuming you have the DB´s 'event_ref ' where 'event date' and 'event
reference number' put in
and 'event_content' where other useful informations are stored
selct a.event_title, from event_ref a, event_content b where b.ref = a.ref
and a.date='2002-04-15'
No dealing with arrays and var_vars, just straight sql.

Lately I have noticed many scripts that all consist of one file even though
they create the appearance of many pages. For example, you would open
setup.php and a form would appear. Then after you complete the form a new
page appears with the results of your form, however the URL is still
setup.php. So basically you can make complicated forms span only one file
instead of having separate file to gather, display and save the data, how is
this done?

Yep, that's what I did -- almost from the beginning I've been doing it this way. Just make sure that any time you refer to data that comes from one of the superglobals arrays, you use $_*['variablename'] instead of just $variablename. So if you have a cookie with a value of Fred and a name of first_name, do $_COOKIE['first_name'] when you want to use that variable -- its value is Fred. The only one that works a bit different is $_SESSION['variablename'] -- it is the easiest way to set session variables. Just do something like // user has submitted POST data, and you have // checked it for errors in your script $_SESSION['variablename'] = $_POST['variablename']; // put POST variable in a session How easy is that! Note that doing this assignment with any other superglobal doesn't work and in most cases wouldn't make sense anyway. For instance, you can't set cookies using $_COOKIE['name'] = $name Erik Erik Price Web Developer Temp Media Lab, H.H.

[PHP] Directory to array to select box...
Ok here is my problem, for one I am new to php and would like a new pair of

putting the contents of a directory into an array and then pulling the

someone could give me some more information on GetDirArray() or a different
way to accomplish this problem that would be great... this is where I am
thus far.
?php
$i=0; // counter
$files = array(); // array to store directory content
// open directory
$dir = opendir(/home/web/b/bignickel.net/htdocs/);
// loop through directory and put filenames into an array

how about that:

while (false !== ($file = readdir($dir)) {

?
/SELECT
INPUT TYPE=submit NAME=submit VALUE=select

/p
in your example there are two mistakes:
1. while ($file = readdir($dir)) is wrong and should be while (false !==
($file = readdir($dir)). (see php manual readdir)
2. $file_count .=OPTION VALUE=\$file\$file/OPTION; is not inside
the loop,
so you will only get the last $file and not all
(3. you probably do not need . and .. in your list, . is a reference
to the same directory and .. to the directory above the current one)

not.
The problem comes because the last element should be empty because all

[PHP] Re: Directory to array to select box...
Ok I tried a different way to do it and this is the resulting code... I
still need to be able to make some hidden fields so the contents of the item
selected may be passed to another script which will stick the path of the
file into a database table if anyone wants to give me a hand with that part.
Here is what I have and it is working as far as just reading the directory
and putting the contents into a select box...
?php
// varible to hold path to directory we wish to open
$dir_name = /path/to/directory/on/server/;
// opening directory
$dir = opendir($dir_name);
// varible to start form
$file_list .= pFORM METHOD=\post\ ACTION=\db.php3\
SELECT NAME=\files\$file_name;
// read the directory and place them into file names for further processing
while ($file_name = readdir($dir)) {
// exclude . and .. file names
if (($file_name != .) ($file_name !=..)) {
// variable to place results of directory into select box
$file_list .= OPTION VALUE=\$file_name\$file_name/OPTION;
}
}
// closing select and form and adding select button
$file_list .= /SELECTbrbrINPUT TYPE=\submit\ NAME=\submit\
VALUE=\select\/FORM/p;
// close the directory
closedir($dir);
?
If anyone knows how to do this in a better way please let me know, but this
works and all it needs is some hidden fields (i am assuming here) so that
the item that the user selects from the list can be further processed, like
sticking the file path (not the actual file) into a database table. (I need
help with that...) Enj0y!

[PHP] conditionaly including classes/functions
Is it okay practice to condtionally include php files that contain

result is a class or function inserted right in the middle of an if{}
block:
} elseif ($var=='a')
{
include('temp.php');
$obj = new foo;
echo $obj-hello();
}
The above code expanded looks like this (below). Works, but it seems
wierd to be able to have a class in the middle of an if{} code block.
} elseif ($var=='a')
class foo
{
function hello()
{
return Hello;

[PHP] Writing to Files
Hey All, I have recently been trying to create some logs for the install script I have been making (to make it easier for me to diagnose problems) but I am wondering how to create and write to text files. I know about the fopen() and fwrite() functions, which theoretically should enable me to do this however I am not exactly sure how I should go about this. Also, I realize that there is limited formatting I can have with text, however I would like to know if its possible to control the line spacing between the entries, and whether or not its possible to indent lines. Lastly, are text files a good idea for logs? Do any of you use anything else I should be aware of?

It is better to do so, since you don't waste the processor's time with
the function/class or include() process if you don't really need it.
However, it can be tricky making sure that these libraries are available
to your code, since there is now a condition determining whether or not
it will be processed.

[PHP] Re: Directory to array to select box...
ok, i'll try to help, but first use while (false !== ($file =
readdir($dir)). ;)
why do you need hidden fields on that page? to determine which file
the user has selected? hmmm...ok, let's see:
The user sees your form, selects the desired file and submits the form.
Now the page processing the request will know which one was selected.
in your case $files will contain the value of the selected option field
within
the select-box files. So why do you need additional input fields for that?
Please explain a bit more detailed what exactly is your problem.

Ok I tried a different way to do it and this is the resulting code... I
still need to be able to make some hidden fields so the contents of the
item
selected may be passed to another script which will stick the path of the
file into a database table if anyone wants to give me a hand with that
part.
Here is what I have and it is working as far as just reading the directory
and putting the contents into a select box...
?php
// varible to hold path to directory we wish to open
$dir_name = /path/to/directory/on/server/;
// opening directory
$dir = opendir($dir_name);
// varible to start form
$file_list .= pFORM METHOD=\post\ ACTION=\db.php3\
SELECT NAME=\files\$file_name;
// read the directory and place them into file names for further
processing
while ($file_name = readdir($dir)) {
// exclude . and .. file names
if (($file_name != .) ($file_name !=..)) {
// variable to place results of directory into select box
$file_list .= OPTION VALUE=\$file_name\$file_name/OPTION;
}
}
// closing select and form and adding select button
$file_list .= /SELECTbrbrINPUT TYPE=\submit\ NAME=\submit\
VALUE=\select\/FORM/p;
// close the directory
closedir($dir);
?
If anyone knows how to do this in a better way please let me know, but
this
works and all it needs is some hidden fields (i am assuming here) so that
the item that the user selects from the list can be further processed,
like
sticking the file path (not the actual file) into a database table. (I
need
help with that...) Enj0y!

RE: [PHP] Directory to array to select box...
When ad_done.php3 is called, it will receive a variable named $files.
Change:
SELECT NAME=\files\$file_name;
to:
SELECT NAME=\files\;
$files will contain the value of the file selected

Hi!
I'm a little baffled on why the array is not working the way I expect
it
to. It showed there is something about the array I do not know about.
Well, it's never too late to learn something new. So, here's the code and
see if you can help me out.
-- clip --
$name = TU4R;
if ($sumItUp[$name] == ) {
$sumItUp[$name] = 0;
} else {
//debug
echo **;
$number = $sumItUp[$name];
$number++;
$sumItUp[$name] = $number;
}
echo $sumItUp[$name].br;
-- clip --
In this case, the if statement never went into else statement when
there's a number like 0, 1, 2, etc. So, what's the heck is happening
here?
When the array, sumItUp[] was empty then the number 0 was assigned and
it work like a charm. So, when this code is repeated again, the if
statement check the array, sumItUp[] and found a number, 0 and it is
not
equal to as shown in the if statement. So, therefore the else
statement
should be executed. But in this case, it never did. I tested it myself
to
make sure I wasn't missing something by putting in the php codes, echo
'**'; and the data, ** was never spitted out on the webpage. So, it
tell
me that the else statment was never executed. So, the problem had to do
with the data in the array itself. So, can anyone help me out? Thanks a
million!!

a transparent include-on-first-use; for a function this

This isn't an answer to your question, but I just wanted to warn you: If you place something like a path in a hidden field, or as part of a select option, you have no guarantee that a user won't change it before submitting the form. Most browsers won't let them, but there are plenty of other ways they can (for instance, debugging web proxies that allow editing of raw form submissions, and so on). So it's VERY IMPORTANT that you don't rely on this path without doing further checks to make sure it's really valid. Otherwise people could try to read or write any file on your system.

Is it okay practice to condtionally include php files that contain
only classes or functions (as opposed to just straight code)? The
result is a class or function inserted right in the middle of an if{}
block:
} elseif ($var=='a')
{
include('temp.php');
$obj = new foo;
echo $obj-hello();
}
It's fine, but since redeclaring functions is an error, better to use
include_once() or require_once().

Re: [PHP] Making sure a post request came from your site
On Friday, April 5, 2002, at 01:15 PM, Miguel Cruz wrote: For security, you can modify your code so that you check the $_POST elements instead of using the magic globals. That's all well and good. However, someone copy and save your HTML to their local machine, change some values, change the Action page of the form to be http://www.yoursite.com/form_page.php instead of form_page.php. You'll be checking the $_POST elements but you won't have any idea that they were changed and posted from the user's local machine. Is there any way to determine from where the post request came from w/o using http_referer? No, nor with it. Someone who wants to mess with you can supply any HTTP referer they want to (using something like 'curl -e' or just creating the request by hand in a text editor). You can never assume that submitted data is benign or untampered. Exactly. I was kind of blown away when I realized how it all works for the first time -- for a few weeks I was assuming that using listboxes or radio buttons was safer than using text inputs, since it limits what kind of data the user can send you. But this was completely false security on my part, because in reality, the user can send you whatever they want -- the browser is only one way to provide this ability to users. Anyone can use telnet to try to send you any POST data they wish, and even the stupidest of crackers can figure out how to send GET data in the browser's Address bar (as you point out in your original post) or modify the value in their cookies. How to make sure that input or other elements of your HTML pages are safe? Religious error checking. Write some decent error checking functions, and then run them on any user-input data you get before you allow that data to have any effect on your code. DevShed recently had an article on the subject of writing a class for form validation: http://www.devshed.com/Server_Side/PHP/FormValidatorClass/page1.html And remember, unless your server is unplugged in a locked room, it's never really safe from intrusion.

RE: [PHP] mysql_fetch_array()

This is for an events calendar, I want all the dates form the db but when I
am generating the individual days for the calendar I need to know whether
there is an event for that day, hence pulling out all the dates from the db.
As I am looping through all the days in a month to dynamically create the
calendar, I do not want to loop through the entire recordset to look for a
date for that day in each iteration.
That sounds like a lot of work (both for you and for the server). Assuming
you want to draw a monthly calendar where each day appears whether or not
it holds any events (it's even easier if you don't need that)...
Just make sure the database returns your results in date order.
SELECT eventtitle, eventdate FROM event WHERE eventdate='2002-03-01'
AND eventdate'2002-04-01' ORDER BY eventdate
Then loop through the days and draw any events that happen to occur on
each day as you get to it:
$row = mysql_fetch_assoc($sql);
for ($day = 1; $day = $num_days_in_month; $day++)
{
print h3$day/h3;
while ($row (date('j', strtotime($row['eventdate'])) == $day))
{
print p{$row['eventtitle']}/p;
$row = mysql_fetch_assoc($sql);
}
}

Re: [PHP] New Server, Bad Attitude
Thanks to Tyler Longren, Hiroshi Ayukawa, and Matt Schroebel for your help. I've made big changes; the encryption thing is still throwing me for a loop, but the other two are fixed up (mostly). __ Do You Yahoo!? Yahoo!
