I cannot help you with code,also it wouldn´t really help you understanding
the problem
but give you more problems understanding my code.
I use to have a table with the following structure
TABLE MENU
rn // that´s an autoincrement number for indexing
page // on which page the component will appear foobar.php3
pt // path to the pic (depending of quantity of path) ../pix/
nop // the name of the pic foo.jpg
altval // the word which will be shown in the alt tag of the pics
reference This is the foopic
link// where will the link go newfoo.php
orm // a number to order the
sf // showflag, to switch off unwanted/uncompleted pages
For pathinformations, I use an includefile which is included on every page.
This holds the informations about tablewidth, pathes(oops that´s correct?),
sitenames
and everything the Site needs on every page.
Now you just make a select like
select * from menu where page=$PHP_SELF where sf=1 order by orm
And make your menu. If you put the menu in an extra page (or an object)
you just have to include it on every content page and the work is done.
echo 'table border=0 width='.$tbwidth.' cellpadding=0
cellspacing=0 summary=Menutable'
while($res=answer from db)
{
echo 'trtd'
echo 'a href='.$res[5].'?somevar=something'
echo 'img src=$res[2] border=0 width=XX height=YY
alt=$res[4]
echo '/a/td/tr'
}
echo '/table'
As you said you want to make a menu, width height of the pics are known.
Otherwise you shoul check them using fuctions from the graphic library.
The Browsers are faster if they know exactly what the do.
Maybe this gives you some understanding how to do it.

[PHP] Tool to remove comments??
Hi Folks, does anybody know a tool for removing comments out of PHP scripts? I mean // this is a comment and /* this is also a comment */ it should also handle something like echo'http://somewher.somecom/somepage'; // this goes to somewhere and multiline comment like /* ..blah */ maybe anybody has an awk script, that he/she will share with me.

Hii,
Actually i want to sort the files form mysql database using php
sorting.I can get the correct result using php sorting if the data's are
stored in the array like this format.
$temp=array(apple,Orange,Gova)
please tell me how i will store the field details in a array fetched from
mysql database
even if you could sort the data with the correct select
f.e. select * from your_db where something='tru' order by
the_field_you_wnt_to_sort,
the method you requested is something like
while($res=result_from_db_select)
(sorry for result_from_db_select but as I´m using objects for
databaseactions, I
don´t know the exact commands maybe mysql_fetch_row)
{
for($i=0; $i count($res); $i++) // counts all fields that come back
{
$temp[$i] = $res[$i];
}
}
if you have a named array, you could also use an array for the names
f.e. $arraynames=array(first_col,second_col,third_col)
the your code would like
while($res=result_from_db_select)
{
for($i=0; $i count($res); $i++) // counts all fields that come back
{
$temp[$arraynames[$i]] = $res[$i];
}

Re: [PHP] PHP session ID not unique or session_register problems
At 18.03.2002 14:54, you wrote:
Even if I did´nt look closely at your code, I would suggest, that
you decrease the amount of data, diferent tables to one table.
You set an cookie, therfor you have the same effect as if you use sesssion
vars.
So it´s easy to set and find the data, via cookie.
f.e.
table:
cookie // here the initial cookie, you sent is stored
varname // what kind of information should be stored
varval // the value of the varname.
timestamp // if you like
now you can save all desired informations according to cookie, have them all
in one place, and can select them to different conditions.
But, what if the user doesn´t allow cookies ??
Hi!
I am a kind of newbie in PHP programming, but I have found an interesting
problem and some php guys I know were unable to help me to solve it. So I am
coming here with my question...
I have written a little more advanced counter, which should be included in
other PHP scripts in website.
It uses cookies, which expire in one year. That helps me to determine which
users are coming back to the website. It also uses sessions (session
cookies) to detect how one user is moving in the website in one session.
Program uses three MySQL tables - table of cookies (cookie ID, number of
visits), table of sessions (session ID, cookie ID, IP, browser,...) and
table of visited subpages in the website (session ID, visited location).
The program flow is simple:
1. Check the cookies. If user do not have a cookie, send it to him. Else
find cookie ID in the database (first table) and increase the counter.
2. Check session ID. If session is not registered, register it and set
'number of session visits counter' to 1, AND save session ID (+ cookie ID,
IP,...) to the second MySQL table.
If session is already registered, just increase the session visits counter.
3. Save session ID and visited location (I use the $REQUEST_URI variable) to
the third MySQL table.
It seems OK, but see what happened.
I explicitely said that if ($sess_visits == 1), variable $sessid is saved to
the second table. That means that $sessid must be unique - it should appear
in a table just once.
But when I exported data from table, I found that some $sessid appeared
twice or three times!
What could be the problem???
See a little bit of my code:
ini_set(session.cookie_lifetime, 0);
// Initialize session
session_start();
// Register session and set number of session visits variable to 1
if (!session_is_registered('sess_visits')) {
session_register('sess_visits');
$sess_visits = 1;
}
else {
$sess_visits++;
}
if ($sess_visits == 1) {
...
// Save session, IP, etc. into database
$sql = INSERT INTO wc_sessionident SET sessid = '$sessid', ...;
...
}
bye, Matej

Even if I don´t understand what your code does, shouldn´t you
give any variable a place to be stored so it schould look like
class foo
{
var $a;
var $b;
function fooplus()
{
$this - a = foofoo;
and so on ??

Does any body know where I can find information about the steps of setting up a server(LINUX) so that people can find a certain URL address? I want to sent up a small server for myself from home with my machine but I don't know how to make it so that the web pages that I put in my server accessable by other people around the world. do I have to connect my modem into my phone line (online) all the time or...??? It sounds, as you are a newbe. Setting up a linuxbox is one thing, getting it in the internet is another. Better way is to look for a provider (maybe free, or free php) to put the pages there. That´s cheaper then having the linuxbox be connected to the internet via a phone-line. (mh.. what about an IP ?) If you want to do PHP, set up a linux server as described in the link (see th other reply) test your stuff locally and when you´re ready put them on the provider´s machine. You´ll save a lot of money and time. look in the archive for free php spaces. HTH Oliver -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
