[PHP] secure access
If I want to secure the access to the database by asking for passwd, what should I do ? I suppose I need a secure connection to transfer the username and passwd between HTML form and the script - how do I make that ? How do I secure the database file with passwords and user names so that it cannot be accessed by anyone, just by allowed users ? thank you roman -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This has been explained a few times. PHP does shallow copies, or
copy-on-write which means that the data is not actually copied until you
change it. That is:
$a = 1234567890;
$b = $a;
internally we do not copy the data from $a to $b until you change $b.
We you use references we have a bit more work to do as we need to decouple
this and indicate that copy-on-write should not be taking place.
Basically things are optimized for the most common case.

I have a couple thoughts...
1) In some other languages, passing an array by value only passes the
first
element value, not the whole array. This may be happening here, which
would
explay the fast execution times. I don't know this for sure, but it could
easily be tested by seeing what's in $a inside the function f().
2) Try returning the array by reference...
function f($a){return $a;}
for ($i=0; $i 100; $i++){$a = f($big);}

[PHP] Session and URL
I meet a probleme with the session.
My example considers 2 scripts :
- the first script (test_session_url.php) opens a session
(session.auto_start=1 in php.ini), defines a counter,
prints some information and an hypertext to execute the second script
which
has session id as parameter
?php
$_SESSION['count']= 1;
echo HTMLTITLESession and URL/TITLEBODY;
echo hello ! : it's .$_SESSION['count']. visit;
echo brbr Information :br;
echo ---name = .session_name().br;
echo ---id = .session_id().br;
echo A HREF=nextpage_session_url.php?;
echo session_name().=.session_id();
echo next page/A;
echo /BODY/HTML;
?
- the second script (nextpage_session_url.php) validates the parameter
(set, empty, value), add one to the counter and then check the value of
the counter. It makes the same thing
5 times by printing an hypertext with itself and after, it prints an new
hypertext to come back to the first script by beginning a NEW SESSION.
?php
if ( !isset($_GET[session_name()]) || empty($_GET[session_name()]) )
{
echo HTMLTITLESession and URL/TITLEBODY;
echo parameter error;
echo /BODY/HTML;
exit;
}
$id= $_GET[session_name()];
if ( $id != session_id() )
{
echo HTMLTITLESession and URL/TITLEBODY;
echo value of session id error : BR;
echo parameter : $id and current session_id :.session_id().--;
echo /BODY/HTML;
}
else
{
$_SESSION['count']++;
if ( $_SESSION['count'] 5 )
{
$_SESSION= array();
session_destroy();
session_start(); // problem is the same with or without this
instruction
include(test_session_url.php);
}
else
{
echo HTMLTITLESession and URL/TITLEBODY;
$cpt = $_SESSION['count'];
echo hello ! : it's .$_SESSION['count']. visit;
echo brbr Information :br;
echo ---name = .session_name().br;
echo ---id = .session_id().br;
echo A HREF=nextpage_session_url.php?;
echo session_name().=.session_id();
echo next page/A;
echo /BODY/HTML;
}
}
?
Now my problem : NEVER a new session (with a new ident) is created.
However I execute $_SESSION= array(); and session_destroy();
I use php 4.2.3 and apache 1.3.26
For testing, I configurate my browser to refuse the cookies (but the
problem
is the same when I accept the cookies).
Perhaps something to change in php.ini ?
In advance thanks.

to send the password too.

Subject: [PHP] Re: MySQL back up
Here is the code I tired to use:
?php
session_start();
You don't need to start a session...
require(./config.php);
$sqlserver = $server1;
$sqlusername = $username1;
$sqlpassword = $password1;
$sqldatabase = $database1;
$nam=date('D,d-m-Y');
@ $db = mysql_pconnect($sqlserver, $sqlusername, $sqlpassword);
You don't need to connect to the mysql server.
if (!$db)
{
echo Could not connect to MySQL;
exit;
}
$backup=@passthru(mysqldump --opt \$sqldatabase\
$backupdir/$nam.sql);
You need to send mysqldump the username and password. Syntax is
Mysqldump -uuser -ppassword databasename filename.sql
passthru(gzip $backupdir/$nam.sql);
Why are you using passthru? Neither of these commands should return any
output, so passthru isn't returning anything. You can use backticks or
exec() instead.

[PHP] Reversing the Colour.
Hi, I have a site whereby the user can select the colour of links for their individual sections. What I would like to do is to get the exact opposite colour of the one that they choose and use that in the 'hover over' option of the a tag. The value for the colour is stored in hex. To add to this, the user can also choose the background colour. I have made sure that they cannot have the same background colour as colour of the link, but obviously if the background colour is the exact opposite of the link colour, then when they hover over the link, it would 'disappear'. In this case I would like to choose HALFWAY between the two sets of colours. I know that this might not always produce the best colour combinations, but I'm trying to get it so that the links always 'stand out'. I cannot let them choose the colour of the 'Hover Over' option unfortunately. Any suggestions as to how to achieve this, especially the calculations, or for that matter improve upon it, would be most appreciated.

[PHP] Different Content-types
Hi everyone, I'm trying to write a PHP script that is meant to conjure up some string context and force the browser to download this context into a file. For this I have used the following header code: header(Cache-control: private); header(Content-Type: application/octet-stream); header(Content-Length: .strlen($file)); header(Content-Disposition: attachment; filename=$filename); where $file is the string to save as a file which value is fetched from $filename. This works like a charm. I get my downloaded file and I am happy. My problem is as follows. I use frames on my site and once I have managed to download the file I lock the browser until I refresh the frame from where I did the download. This is annoying. I have read the documentation on the header() function and I also checked the RFC for Content-Disposition and noticed you can add multipart content to a page but all my efforts go awry. The following is written by me and is my interpretation on how things should look. Instead of downloading the first content and then displaying the second, it downloads everything. Any ideas? header(Content-Type: multipart/mixed; boundary=outer); header(Cache-control: private); header(Content-Type: application/octet-stream); header(Content-Length: .strlen($file)); header(Content-Disposition: attachment; filename=$filename); $fp = fopen($filename, r); fpassthru($fp); header(Content-Type: text/html); header(Content-Disposition: inline); echo PTest/P; Thanks in advance, Archie --- Archibald Zimonyi [EMAIL PROTECTED] There is no logic like no logic -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Encrypting passwords in a flat file before import
Off the top of my head I would use:
$f = fopen(filename.csv,r);
$data = fread($f,filesize(filename.csv));
fclose($f);
$split = explode(\n,$data);
$counter = 0;
foreach($split AS $row)
{
$myarray = explode(,,$row);
$myarray[2] = md5($myarray[2]);
$split[$counter] = implode(,,$myarray);
$counter++;
}
$save = implode(\n,$split);
$f = fopen(outfile.csv,w);
fwrite($f,$save);
fclose($f);
Don't quote me on that though since thats just off
the top of my head.

Hi,
I struggled with the same issues a few months ago, and coded a function for
brightening or darkening a HEX color.
Maybe it can help you in your dilemma.
The code converts HEX to RGB, multiplies each color channel
and converts back to HEX. This way the hue stays correct. The function
could of course have been written in more concise manner, but as I'm
only learning PHP more deeply, I like to write code that even I can
understand :)
function hexcolorshifter($color,$amount)
{
$r = hexdec(substr($color, 0, 2));
$g = hexdec(substr($color, 2, 2));
$b = hexdec(substr($color, 4, 2));
$new_r = abs(intval($r*$amount)); if ($new_r255) $new_r=255;
$new_g = abs(intval($g*$amount)); if ($new_g255) $new_g=255;
$new_b = abs(intval($b*$amount)); if ($new_b255) $new_b=255;
$hex_r = sprintf(%02X,$new_r);
$hex_g = sprintf(%02X,$new_g);
$hex_b = sprintf(%02X,$new_b);
// print line is only for debugging:
// print R: . $new_r . , . $hex_r . G: .
$new_g . , . $hex_g . B: . $new_b . , . $hex_b . br;
$color = $hex_r .$hex_g .$hex_b;
return $color;
}
Use it like this:
$my_bg_color = hexcolorshifter($my_bg_color,.8);
If you brighten a color, each channel will clip at 255, so in
situations where you have light source color you will most likely have
hue shifts if channels don't clip 'equally'.

[PHP] Object methods - memory usage?
Hello! Ok, this is probably a very stupid question for someone who knows how these things work internally - but I don't, therefore I ask. :) When I instantiate an object, do the methods get instantiated as well? The question is asked memory-wise, not functionality-wise. More to the point, if I instantiate many identical objects with no class variables of their own but with many methods, will I get memory used up for the methods? If I were to guess, I'd say no extra memory is used for the methods since I don't think you can dynamically redefine class methods, so there would be no reason for duplicating them instead of simply referencing the class definition - but then again, I don't know how PHP works internally...

Re: [PHP] Reversing the Colour.
Assumptions:
- background colour is stored in $bgcol (ie 4592FF)
- chosen link colour is stored in $lncol (ie *same as above*)
- Finds half-way colour between $bgcol and $lncol (returns a RRGGBB in hex
as above)
Notes:
This is actually fairly simple Alexis.. Simply convert your hex vals to
something you can work with (ie dec) using hexdec() and then do some basic
maths to find the half way between each of the R G B vals and then finally
spitting out a hex value for the midway mark..
Implementation:
?php
/** Func: getMidColour **/
// Returns the midway value in HEX between the two DEC values $dec1, $dec2
function getMidColour($dec1,$dec2) {
return
dechex(abs(hexdec($dec1)-hexdec($dec2))/2+(hexdec($dec1)hexdec($dec2)?hexde
c($dec2):hexdec($dec1)));
}
// Parses 6char hex colour (RRGGBB) into 3 part RGB string and feeds into an
array
$bgcol_arr=split(,,preg_replace(([\d]{2})([\d]{2})([\d]{2}),$1,$2,$3,$
bgcol));
$lncol_arr=split(,,preg_replace(([\d]{2})([\d]{2})([\d]{2}),$1,$2,$3,$
lncol));
// We now can access the hex RGB values through the [0],[1],[2] elements of
these arrays..
// Using our custom function we can throw into our final array the actual 3
hex values
// desired which is the midpoint between $bgcol and $lncol

;
$lncol_arr=split(,,preg_replace(/(.{2})(.{2})(.{2})/,$1,$2,$3,$lncol))

// We now can access the hex RGB values through the [0],[1],[2] elements of

// Formats the array into a string and Upper cases it..
$midcol=strtoupper(join(,$midcol_arr));

You then have the $midcol var which holds a uppercase HTML hex colour string
which represents the midway colour between $bgcol and $lncol..

Subject: [PHP] confirm box
Hi people,
Maybe a bit off-topic, but i thought lets ask anyway. I have a guestbook
admin page were i can delete multiple items from the database using
checkboxes. So when i click on the Submit button i would like a
javascript confirm box coming up. I have done that, but it deletes the
item(s) anyway, also if i click on cancel.
This is my javascript code in the head of the document:
script language=JavaScript type=text/javascript
!--
function ConfirmDelete()
{
input_box=confirm(Are you sure that you want to delete the
selected items?);
if (input_box!=true)
{
return false;
}
else
{
return true;
}
}
//--
/script
This is what i use in my PHP code:
?php
//Guestbook admin page
echo
form name=\admin\ onSubmit=\ConfirmDelete();\;
//The rest of my form
echo
input type=\submit\ name=\submit\ value=\delete\
/form;
?
?php
//Delete items from guestbook
if(isSet($submit))
{
//Delete items
}
?
Any help is appreciated, thanks for your time,

you want to delete??')
Hope that helps,

[PHP] site path
Hello guys I'm just looking for some advise: I've got a variable which I use to store my site's main path. Is it better to have it like this: $site_path = /my/web/path/ or like this: $site_path = http://my_url.com/; ? What about the trailing slash?, should I use it or not?

[PHP] Image problem
I upload an image. Once I upload this image using the is_uploaded_file function, then writing this image file using the copy function. Everything seems to work fine. When i try to update (that is uploading a new file and saving it with the same name as the first file created) it shows the first image instead of the second image. So what I did was closed my browser, then reopened it, then everything was ok. So I figure that I have a cache problem. I then tried using the clearstatcache() function right after I update this image file. But it did not seem to work. So am I going to have to close and reopen my browser to see these changes take place or is there something else I can do? Ben __ Do you Yahoo!?

[PHP] Re: secure access
I belive you can have the file atleast one directory below your root web folder (so web surfers have no access, just your script). Also since the HTML-PHP is unsecure over HTTP, look into HTTPS , I believe this is related to SSL (Secure Socket Layer). Without SSL, you will be POSTing your user/pass enter from the HTML form in plain text, which is always a target for packet sniffers. Hopefully that will shed some light, BUT I myself am not familiar with SSL so please check with a more experienced/knowledged person.

Re: [PHP] Re: secure access
If you use a .htaccess file in the directory (assuming Apache), a popup box asks for username/password. The password is MD5 encrypted. I think the downside is php getting access to these, or maybe I'm wrong in this.

Re: [PHP] Re: secure access
1. SSL will encrypt the data sent between the browser and the server, 2. Depending on the database, it should have it's own authentication mechanism which the PHP script needs to pass before the database will allow access. 3. Depending on what you need to do, you can limit the use of system username/passwords even more by setting up your own username/password list just for the specific database, which is not part of the database engine itself... I might be goin too far ahead of myself, but those are some options..

[PHP] Spiders, Sessions, trans SID, and mod_rewrite
Hello I'm preparing to start an ecommerce project that will require the use of sessions throughout the entire site for referrer and affiliate tracking purposes. I also plan to use mod_rewrite to make links to dynamic content search spider friendly. example: instead of /somescript.php?var1=value1var2=value2 I'll have /somescript/var1/value1/var2/value2 The obstacle I'm facing is the automatic appending of the session id to every link upon first entering the site and to every link on every page of the site if session cookies are disabled. This will make search spiders either not index the linked pages, or worse index them with an old session id! I am hoping to find two solutions to dealing with this inherent problem with sessions, spiders, trans sid, and url rewriting. 1) I am thinking of obtaining and using a list of known spiders to determine if the visitor is a spider. If they are a spider I simply won't call session_start() thus eliminating the auto appending of the session id to every link. URL rewriting will take care of the ugly query strings and I'm in business to get spidered. How ever, this could mean a lot of overhead if the site gets busy and a lot of work keeping an updated spider list. Does anyone have a solution for this? I want some real world experience here please. 2) If I rewrite query strings how will I deal with trans sid? For instance, I have a rewritten url that looks like this: /somescript/var1/value1/var2/value2 and the session id is going to get appended leaving me with this: /somescript/var1/value1/var2/value2PHPSESSID=some_session_id. Is there a way to make php add the session id in the slash delimited format? I am aware of arg_separator.output directive but that does not fix the = in the query string. I appreciate any help, tips, and/or pointers. The problem is clear - it's the solution that's a little fuzzy! Thanks for reading, Jim
RE: [PHP] Spiders, Sessions, trans SID, and mod_rewrite
I would suggest that you look at php as the total solution not mod_rewrite that way you have access to include the PHPSESS information into the URL directly eg: http://www.yourhost.com/application/first_name/john/sess_id/99f9f99f9f9f 9ijfjf9f/cart_full/yes You can achieve this by reading the following artcile... we use it for websites that will be searchable by bots with great success. http://www.phpbuilder.com/columns/tim19990117.php3 Oh and on the bot side of things... simply have an expiry (epoch stamp) in the url that you read and if that has expired simply reload the page with a new session... oh and you will experience the same problem with bookmarking visitors as well as bots with the expired sessions.. or you could just simply say if it doesn't exist recreate... it depends if you are going to use built in session handlers or user (eg database) or even custom self written (my suggestion for your situation - write your own env).

[PHP] Found the problem with the libmcrypt.....
Found the problem with libmcrypt-2.5.3. When I configured PHP using the --with-mcrypt option and the PHP configuration found libmcrypt without a problem. After compiling and installing it. Once I fired up Apache. I checked the PHP Info using phpinfo() function. The mcrypt showed up but there is no support ciphers (algorithms modes). So, I had to use the php.ini as the PHP Manual stated on 'http://php.net/mcrypt'. So, I added the two lines as shown in the clipping where libmcrypt was installed in. --clip-- mcrypt.algorithms_dir = /usr/local/lib/libmcrypt mcrypt.modes_dir = /usr/local/lib/libmcrypt --clip-- That is when PHP Info showed the 'mcrypt.algorithms_dir' and 'mcrypt.modes_dir' with data in it. But the problem is I still get the error message when I tried any mcrypt function, the error message range from being unable to initalize the module to whatever the other error messages are. I assumed there's a bug and filed a bug report to PHP but was rejected because I was told that I had the php.ini incorrect. That doesn't make sense. It took me a long time to find some clues to the problem. What I found is that with any files in the /usr/local/lib/libmcrypt that end with *.a and *.la, they don't work. There is no *.c and *.h files in that directory. I discovered that when I set the php.ini to point to the untarred libmcrypt directory where *.c and *.h are found in both '/usr/local/src4/libmcrypt-2.5.3/modules/algorithms' and '/usr/local/src4/libmcrypt-2.5.3/modules/modes'. That's when the mcrypt function start working without a problem. The problem is PHP doesn't work with the *.la and *.a files. Again, I saw the OpenSSL directory where *.c and *.h files are found in both the algorithms and modes directory of the '/usr/local/ssl/include/openssl/' directory, it work just fine too. This had lead me to question of whether is there a bug in libmcrypt or php. You be the judge of it. It would be so nice if this problem can be resolved. I'm not sure if I'm allowed to use the open source code instead of the compiled codes. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Encrypting passwords in a flat file before import
I think that generally you do not want passwords to be decryptable. What I normally do is try to encrypt whatever the user enters as a password and compare the resulting encrypted string with what's in the database to make sure they correspond. If the encrypting function is univocal (and md5 is) then the correct password will always return the same encrypted string. On Wed, 2002-10-09 at 16:06, Scott Fletcher wrote: Can it be de-encrypt???

RE: [PHP] Encrypting passwords in a flat file before import
The potential problem with a firewall is your web server must be able to connect to the database, that means if someone gets sloppy in the PHP code or just doesn't realize something is a security issue OR there is an exploit found for apache or PHP the attacker can get access to your server without ever being blocked by the firewall. I see your point as well however if you are going to bother to encrypt the passwords why not use a more secure method? If passwords are already encrypted in the database it is trivial to write a tool to decrypt them, convert them to an md5 hash and update the passwords. Forcing the user to change passwords is a good idea, however I would still use a hash instead of reversible encryption because it is easy to implement and increases security transparently to the users and I can think of no good reason to need to know what the users passwords are (keeps system administrators as well as attackers honest). This is not hostile, I just come from system admin background and believe in making an application more secure if it doesn't affect the end user adversly :) Jason -Original Message- From: Scott Fletcher [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 09, 2002 2:48 PM To: 'SHEETS,JASON (HP-Boise,ex1)'; Scott Fletcher; [EMAIL PROTECTED] Subject: RE: [PHP] Encrypting passwords in a flat file before import Hi!

Re: [PHP] Encrypting passwords in a flat file before import
Or if you use md5() which encrypts the same way every time you could just get a CD-ROM with a trillion different character combinations that could be valid passwords and encrypt them, then compare the encrypted strings With the current hardware available that might take..oh a half a second ro so. So, it's more important to protect the actual SOURCE then the information stored in the source.

As far as I can see that leaves me with only Active Server Pages in
which to access this database or am I wrong?
You can use PHP, of course. ODBC or COM.
Here is an example some program automatically created that shows how to
connect to and query an Access database:
$conn = new COM(ADODB.Connection) or die(Cannot start ADO);
$conn-Open(Driver={Microsoft Access Driver (*.mdb)};Dbq=
.realpath(datab/test.mdb). ;Password=;);
$SQL=SELECT COUNT(*) AS Count FROM test;
$countx = 0;
$rs = $conn-Execute($SQL);
while (!$rs-EOF) {
$countx = $rs-Fields(Count);

[PHP] problem with SUM and Postgres
I can't figure out why the following code is not returning a column total: $sql1 = SELECT SUM(hostingcost) FROM $tablename WHERE webserver = '$webserver'; $hosting = pg_exec($connect, $sql1); echo $hosting; This returns: Resource ID #3 The only thing I can think of is that the hostingcost column's default value is set to MONEY which is a postgres specific constraint.

Re: [PHP] problem with SUM and Postgres
Because pg_exec only executes the query and returns the resource that's associated with the returns. If you want to read the results, you should use pg_fetch_result(): $sql1 = SELECT SUM(hostingcost) FROM $tablename WHERE webserver = '$webserver'; $hosting_rs = pg_exec($connect, $sql1); $hosting_data = pg_fetch_row ($hosting_rs, 0); $hosting = $hosting_data[0]; Marco On Wed, 2002-10-09 at 19:29, webmaster wrote: I can't figure out why the following code is not returning a column total: $sql1 = SELECT SUM(hostingcost) FROM $tablename WHERE webserver = '$webserver'; $hosting = pg_exec($connect, $sql1); echo $hosting; This returns: Resource ID #3 The only thing I can think of is that the hostingcost column's default value is set to MONEY which is a postgres specific constraint.

[PHP] CC Processing Merchants
Sorry for this slightly off topic question, but I beleive many of you will have delt with this kind of thing before. My client is asking for a Online Merchant that will allow him to validate and charge credit cards. He orginally suggested Pay Pals but after I read their docs I found that the Customers would have to sign up for a Pay Pals account, which my client dislikes. So can anyone recommend a good (maybe cheap) Merchant that can validate and charge credit cards online?

Re: [PHP] Found the problem with the libmcrypt.....
Hi, Thursday, October 10, 2002, 5:35:12 AM, you wrote: SF Found the problem with libmcrypt-2.5.3. When I configured PHP using SF the --with-mcrypt option and the PHP configuration found libmcrypt without a SF problem. After compiling and installing it. SF Once I fired up Apache. I checked the PHP Info using phpinfo() function. SF The mcrypt showed up but there is no support ciphers (algorithms modes). SF So, I had to use the php.ini as the PHP Manual stated on SF 'http://php.net/mcrypt'. So, I added the two lines as shown in the clipping SF where libmcrypt was installed in. SF --clip-- SF mcrypt.algorithms_dir = /usr/local/lib/libmcrypt SF mcrypt.modes_dir = /usr/local/lib/libmcrypt SF --clip-- SF That is when PHP Info showed the 'mcrypt.algorithms_dir' and SF 'mcrypt.modes_dir' with data in it. But the problem is I still get the SF error message when I tried any mcrypt function, the error message range from SF being unable to initalize the module to whatever the other error messages SF are. I assumed there's a bug and filed a bug report to PHP but was rejected SF because I was told that I had the php.ini incorrect. That doesn't make SF sense. It took me a long time to find some clues to the problem. What I SF found is that with any files in the /usr/local/lib/libmcrypt that end with SF *.a and *.la, they don't work. There is no *.c and *.h files in that SF directory. SF I discovered that when I set the php.ini to point to the untarred libmcrypt SF directory where *.c and *.h are found in both SF '/usr/local/src4/libmcrypt-2.5.3/modules/algorithms' and SF '/usr/local/src4/libmcrypt-2.5.3/modules/modes'. That's when the mcrypt SF function start working without a problem. The problem is PHP doesn't work SF with the *.la and *.a files. Again, I saw the OpenSSL directory where *.c SF and *.h files are found in both the algorithms and modes directory of the SF '/usr/local/ssl/include/openssl/' directory, it work just fine too. SF This had lead me to question of whether is there a bug in libmcrypt or php. SF You be the judge of it. It would be so nice if this problem can be SF resolved. I'm not sure if I'm allowed to use the open source code instead SF of the compiled codes. You dont normally need to specify anything in php.ini for it to work just make sure you have --with-mcrypt=/usr/src/mcrypt-2.6.x (thats where it was untarred) when you configure php.

[PHP] PHP problem
Hi there, I need some help here: 1 - I have a table created on a DB where I insert the data that I want. 2 - I have a submit page to submit the info I want to the DB 3 - I have a page that displays the info from the DB (choosed by id) 4 - I have a page where I have a text box field and a button. When i want to submit some info to database, I give the pretended id (not auto_incremment), for example 11 and the rest of the info. The info is inserted and the id is 11. Now, I want to see the info with the id 11, so I use the page with the text box filed and insert the ID 11. When hit OK, i want to see the info of id 11 displayed on the (for example) info.php page, where ?id=11. If i insert the id 12 and if it exists, I want to see the info displayed on info.php page, where ?id=12. Any soul can give me a possible code to use on the search form, in order to see the info displayed on the info.php page?? Thx Miguel

[PHP] displaying a select number of rows from a sql query
Ok, here is the question:
I have a sql query, nothing special. It has 3 variables. I have created the
php code to display the variables in context with the html code. I need it
to loop a select number of times, most likely twice, and therefore display
the first two rows of the query.
In other words, querying the database for a set of rows, it needs to display
the first two of the rows on the page.
Here is the code I have tried so far, which has either looped continuosly or
displayed the top row twice (edited for security):
?php
$sql = SELECT * FROM [database] ORDER BY [collumn] LIMIT 2;
$result = mysql_query($sql) or die(problem with $sql);
// list($title) = mysql_fetch_array($result);
?
td width=48% align=left valign=top
h3What's New?/h3
?php
/* It tried this: */ while(list($link, $title, $content) =
mysql_fetch_array($result)){
/* And this: */ while($row = mysql_fetch_array($result) and (($count++)2)){
// The first kept looping infinitely, the second displayed the top row
twice. Grr... _
?
h4

mysql_result($result,0,title); ?/a
/h4

}

[PHP] Re: displaying a select number of rows from a sql query
With the line:
while (list($link, $title, $content) = mysql_fetch_array($result)) {
The php docs don't actually say what the list() function returns, but since
your getting an infinite loop i would say that it probably evaluates to
true no matter whats on the right hand side of the assignment. I would
suggest that you use:
while ($tmp = mysql_fetch_array($result)) {
list($link, $title, $content) = $tmp;

[PHP] Re: Extract HTML tags
If you can guarantee that your body tags are lowercase and have no args, then I would check out strtok() in the string functions. If your body tags are not that easy to match then I suggest you use either a regex or write a state machine to parse the string. A good html parsing state machine is in the php source for htmlstriptags. Note that Regex's are extremely expensive on large strings.

[PHP] Multi-Dimensional Arrays
I am trying to create an array to hold shopping cart information. The array I am using is called cartArray.

Then the next time a product is added it appends then new information as a second sub-array to cartArray and so forth. Following is some code I have been using to test with and so far PHP will let me use .= to append but when I try to call it back with print_r or echo array[][] only the first entry is returned. Any ideas what I am doing wrong? $brand=Brand1; $itemnumber=456789; $itemname=Some Item Name; $itemqty=3; $cartArray[] .= array(0=array($itemnumber=$brand, $itemqty, $itemname)); print_r($cartArray).BRBR; $brand=Brand2; $itemnumber=123456; $itemname=Another Item Name; $itemqty=9; array_push($cartArray, array($itemnumber=$brand, $itemqty, $itemname)); print_r($cartArray).BRBR; echo $cartArray[0][0].BRBR; Thank you, Jonathan Duncan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
