Re: [PHP-DB] Why use MySQL with PHP
Oh PHP itself isn't to blame at all, and I never intended to infer that. If you point the W3C validator at www.foxjet.com you will get a clean rating and that page is generated via PHP. Someone mentioned that they got errors in Netscape and I was just pointing out that for some reason the people who built www.php.net didn't make the page W3C compliant.

It's the person's html/php coding ability to avoid coding mistakes. Basically, PHP gives functionality. A part of that functionality is for the php programmer to make correct HTML as output so the browser will render a page as output correctly. If the php programmer is a real bonehead and he/she can't instruct php to return good HTML that doesn't make a HTML validator from coughing up errors, it's not PHP's fault, it's the coders. I've been programming PHP for quite a while now and I can't think of a single regular thing in PHP that'd cause any browser (Netscape or IE) to hang. Any time that I've had problems, it's because I didn't know the limits of what I was coding to try and do something that is outside the possibilities. Whether it's storing information in a database, retrieving information from a database, sending PHP headers to redirect to another page or sending PHP headers to set a cookie, etc. You have to know when you can do things in PHP and when you can't. If web pages hang in a browser, it's the buggy PHP code that is interpreted that's causing the problems. Not PHP itself. It's like putting gasoline w/ water in a gas tank. It's not the engine's fault it's spitting and sputtering. It's the fuel supply.

Re: [PHP-DB] Why use MySQL with PHP
I use PHP/MySQL for a few reasons.
1) Ease of Use - I am a Computer Science student and a Web Programmer. As
such have been exposed to a wide variety of programming languages and
environments. PHP/MySQL is one of the easiest to work with and learn, and
is THE easiest to do Web related things with (and yes, I have used and am
including ASP in that statement).
2) Availability - By this I mean not only that both PHP and MySQL are free
(which is a big factor for us starving student types), but that they setup
very easily on a variety of platforms. This means I can test scripts on a
copy of the MySQL DB from my Linux Server on my windows box before uploading
them.
3) Support - Both PHP and MySQL have very good Manuals which are very easily
accessable (both online and downloadable). In addition, I have received
extremely valuable help from the PHP mailling lists on both PHP and MySQL
questions. In most cases I have gotten faster and better responses than I
get from professors at school (who I am asking things concerning their
class...not PHP =P ) who I am paying to teach me. That alone is quite a
strong arguement.
4) Good Balance between Flexibility and Readability - In PERL they have a
saying There's More Than One Way To Do It. I think this is a good
philosophy, but PERL takes this to more of an extreme than I like (this is
not to say that this extreme is not right for some people). When I read
through a 50 line program in a language that I am fairly skilled at I
shouldn't have to refer to the manual more than say a dozen times...right?
In Perl I often find myself having to refer to manuals a dozen times for two
or three lines! For example:
perl -we '$_ = q ?4a75737420616e6f74686572205065726c204861636b65720as?;??;
for (??;(??)x??;??)
{??;s;(..)s?;qq ?print chr 0x$1 and \161 ss?;excess;??}'
Any idea what that one does? Without running it? Paste it into a
terminal... it should run as is (does on my Linux box with PERL 5 anyway).
On the other hand, having to write in languages where you have strict types
(You want to treat a variable as an int and then as a string?!?!?!?) and
very structured design is just as distasteful to me. PHP strikes a very
good balance between the two even when working with MySQL (I won't paste any
of the kludge needed to interface with CGI and DB in other languages... but
if you have some free time look some of these programs up).

Hi everybody
I'm writing a synopsis about PHP and mySQL.
I'm hoping someone can help me, and tell me why
the combination og PHP and MySQL is so common.
What makes MySQL such a good choice when using PHP?
What seperates MySQL from others dbms?

Re: [PHP-DB] UPDATE table1 FROM table2
This is actually one of the more common MySQL problems which doesn't have an easy answer. The best I can offer is a bit of a kludge... but it does work. The trick is to use the Replace...Select command. The problem with this is that you can not select from the table you are replacing. But if you make a temporary copy of the tabe you are updating, then what you are wanting to do can be done with $query = create temporary table temp select * from table1; replace table1 select temp.id,table2.value2,temp.colname from table2 left join temp using(id); You just have to make sure all of the columns in table1 you don't want changed appear as temp.colname. The temp table will only exist as long as the thread does, since it was created with the temporary keyword.

Re: [PHP-DB] Embedding Perl
You have to put the actual command in the exec or backticks as you would
type it in your shell, not just the filename. So instead of
$out = `convert-pdf.pl Blank.gif`;
Try
$out = `perl convert-pdf.pl Blank.gif`;

Ok, I found snippets that talk about using either exec() or backticks.
The problem is that it still doesn't call the perl script. Or at least
doesn't seem to.
exec(convert-pdf.pl Blank.gif,$out);
echo(implode(\n,$out));
$out = `convert-pdf.pl Blank.gif`;
echo($out);
If I run
perl convert-pdf.pl Blank.gif
from the shell, it responds with 135x105 and creates a secondary file.
This is what the script is meant to do. Calling it in either of the
example above, results in either an Array or nothing being displayed. No
secondary file gets created.

Alternatively, is there a module that can take a pdf file and make a

But now i want to understand it too. bit_count(bit_or(1table1.sid)) ?? okay... 1table1.sid is leftshift the number 1 table1.sid times. Your result will be a binary number... which will be the number 1 followed by table1.sid 0's. Once you have this you do a bitwise or of all the numbers you have shifted. This means any two rows where sid was the same will be combined, as there is no difference between (1 or 1) and (1 or 0). The last step, then, is to count the 1 bits and see how many different sid's there were. Make Sense? The problem before was that there was no way to differentiate one row from another, and thus no way to combine identical rows =P What does bit mean? I thougt 1table1.sid was something like a backward bit(e)swich stepsize 1?? I creat my sid by: srand((double)microtime()*100); $sid = md5(uniqid(rand())); a the sid-field as varchar(32) (i realise now, maybe better use char(32)) (Maybe you will ask why i don't use a auto_increment sid (int(9) or something like that). Cause I don't want the table will be full ever (sid999.999.999)) ACK! Don't do this. You do know that an unsigned int (using a signed int in an auto_increment field is pointless anyway) has a max value of 4294967295, right? To put this into perspective... if you had one million customers, they would have more than 4294 transactions EACH before sid filled up. If you are still worried about running out of numbers in your sid field make it an unsigned bigint. The max value for an unsigned bigint is 18446744073709551615... so that should give you lots of space to play in, and sid will only be 8 bytes per row... not 33 (Also incidentally, if you do want to save an md5 value to a row in the future... use char not varchar as you know it will be 32 bytes and are adding a wasted 33rd byte). (If you need more than 18 Quintillion transactions, which comes out to around 3 billion transactions for EVERY PERSON ON EARTH, please let me know what kind of business you are in... as I am obviously in the wrong one =P ) Now i thougth bit_count(bit_or(32table1.sid)) should do the trick, but it doesn't? See my explanation above. All you are trying to do is shift a 1 digit to a different place for each unique value of sid. The above definately won't work if sid is an md5 value as md5 includes a-z characters.

If you had a Billion hits a day, you would not run out of possible sid's for approximately 50.5 million years.

The above Select would return 35 rows, because the join (,) tells it to return a set with every combination of fielda and fieldb (1,1 2,1 3,1 4,1 5,1 1,2 etc) So SELECT SUM(fielda.table1),SUM(fieldb.table2) FROM table1, table2. Will calculate every possible combination of fielda and fieldb and then give you the sums of each column in that set (105 and 140 in my example). Does that make sense?

I'm not sure how to get the order of the pics in the first place or what do with the picnumber column. If someone deletes a pic wouldn't the picnumbers higher than it also need to be changed? I'm understanding everything else, even the password stuff but this I'm just clueless. Jeff Oien I would add the field picnumber int or something to your DB. This is where the pic falls in the order of pics in the album. The the previous and next should be as simple as doing select picnumber,piclocation from album where user=$user and (picnumber=$number-1 or picnumber=$number+1); Then just check numrows. If two make both prev and next links, if one make prev link if $return[0] $number else make next link. If none, no links. This way, if the person wants to change the order of their pictures it is quite easy to write a function that allows them to swap the place of two pics. Make sense?

$1$arjq575D$rnHVFfcQE7.h2EgSU7yzQ1
Why results are different?
Unix Shadow passwords are actually computed using an alogrithm, md5 is part
of that algorithm but not the entire thing. You can immediately tell that
$1$arjq575D$rnHVFfcQE7.h2EgSU7yzQ1
is not an md5 hash because all md5 hashes are 32 characters and this is 35.
Shadow passwords computed with this algorithm are start $1 and then have a 8
character salt surrounded by $'s. The last part of the hash is 22
characters which
are computed by the algorithm. So in the above string $1$ indicates that it
is a shadow
password, and arjq575D is the salt followed by $. I looked around on google
for a bit, but
could not find the specifc algoritm Debian uses to compute the last 22
characters. I'll let
you know if I find it. You might also want to try this script:
http://limonez.net/~jure/php/md5crypt.phps
I noticed it in the user notes for md5. It says it makes FreeBSD style
shadow passwords
though, and I am not sure if FreeBSD uses the same algorithm as Debian or
not.
(I also have not actually verified that the above script does ANYTHING =P )
Good luck. I'll let you know if I find anything specific on Debian.

Assuming you've opened a MySQL connection and stored connection in

print TABLE;

print /TABLE;
mysql_free_result($result);
The above will create a table and output one table row per row in

Change field1, fiedl2, field3 to the names of fields in the database.

Re: [PHP-DB] Photo Album Schema
I suggested a naming scheme, but as I think about it that may be overcomplicating things. You may want to, instead, create a directory for each user with their name. This has several benefits. The first is that it is an easy way to avoid conflicts. If Rick and I both upload an image 'beach.jpg' one won't be overwritten. The second is that if you also create an index.php page (as simple as copying a template) when you create the directory the user will be able to see their album by simply visiting www.youralbum.com/username Finally, this opens up a variety of possibilities for the future. Things like FTP access, and having random pictures on the user's initial album page wouldn't be too dificult with this setup.

Re: [PHP-DB] Photo Album Schema
That is a good point. I see two obvious answers. Instead of id . filename he could use id . + . filename (or any non alphanumeric character instead of +) first running the filename through an ereg to strip any non-alphanumeric characters. The other is to require that the first character in the filename be alpha... which is also easily enforcable with a simple ereg.

The biggest bottleneck in a server-side script is usually the DB calls. With this in mind, you want to limit these calls as much as possible. I would suggest setting up a naming and/or directory scheme to store the pictures on the website, and then store the URL of the picture in the DB, rather than the image itself.

You may want to, instead, create a directory for each user with their name. This has several benefits. The first is that it is an easy way to avoid conflicts. If Rick and I both upload an image 'beach.jpg' one won't be overwritten. I would prefer to store the picture's original name in the database and on your site use unique generated names... this would allow a single user to have a number of pictures all named 'beach' (for instance). The name that is shown with the picture when the Album is viewed should be determined by the photo_title field in his DB, and not by filename. The actual filename should only be visible to the person who owns the album. It would be inappropriate to present him with half a dozen filenames which are all beach when he is trying to delete a specific picture from the album =P I would not use per-user directories; rather, I would split them by upload time and/or sessionID. This should give a more even distribution, and be directly useful for load balancing etc. I just suggested per-user directories for ease of access for the user. Any number of other possibilities do, of course, exist. Finally, this opens up a variety of possibilities for the future. Things like FTP access, and having random pictures on the user's initial album page wouldn't be too dificult with this setup. Here's a question - how hard is it to set up a virtual ftp dir, linked to arbitrary specified files? I would imagine it would be more difficult than setting up a virtual ftp to a specific directory... but I will admit that I may be wrong as this is not my area of expertise.

Re: [PHP-DB] Member authentication with PHP and MySQL
I would use either cookies or sessions for this.
First Check for the cookie, and verify its contents.
If there isn't a cookie then do the login prompt like you
are doing now.
Here's some pseudocode to give you a quick idea of what I mean
if (isset($cookie)
{
if (CheckCookie())
{
SiteContent();
} else {
Kill Cookie
GiveLoginPrompt();
}
} elseif (isset($login) {
if (CheckLogin())
SetCookie();
} else {
GiveLoginPrompt
}
On all the other pages on the site you just have a header check the
cookie and redirect to the login page if it doesn't check out
ie:
if (!isset($cookie))
{
header(Location: http://www.yourdomain.com/login.php;);
exit;
}
if (!CheckCookie())
{
header(Location: http://www.yourdomain.com/login.php;);
exit;
}
If you want to use sessions just replace cookie with session =P
Here is an example script I wrote a while back if you want to
see more than metacode
http://www.zend.com/codex.php?id=393single=1
And here is the header for other files on the site using the above script
http://www.zend.com/codex.php?id=397single=1
Let me know if this helps

Subject: [PHP-DB] Member authentication with PHP and MySQL
Hi!
I'm trying to authenticate members by using php and MySQL.
This is what I've come to so far:
?php
$auth = false; // Assume user is not authenticated
if (isset( $email ) isset($password)) {
// Connect to MySQL
mysql_connect( 'localhost', 'Xephiroth', 'lordoftherings' )
or die ( 'Unable to connect to server.' );
// Select database on MySQL server
mysql_select_db( 'members' )
or die ( 'Unable to select database.' );
// Formulate the query
$sql = SELECT * FROM memberinfo WHERE
email = '$email' AND
password = '$password';
// Execute the query and put results in $result
$result = mysql_query( $sql )
or die ( 'Unable to execute query.' );
// Get number of rows in $result.
$num = mysql_numrows( $result );
if ( $num != 0 ) {
// A matching row was found - the user is authenticated.
$auth = true;
}
}
if ( ! $auth ) {
header( 'WWW-Authenticate: Basic realm=Members only' );
header( 'HTTP/1.0 401 Unauthorized' );
echo 'Authorization Required to enter the member area';
exit;
} else {
echo '
-SITE CONTENT-
'; } ?
How do I make the authentication to go to site:
members.php?charnick=$charnick
Where $charnick is brung from the DB line who was authenticated?
So that Peter won't end up at John 's membersite?
Thanks for your time and expertese!
Best regards Cato

Re: [PHP-DB] Member authentication with PHP and MySQL
If you note the part of the script where the cookie is set //make unique session id and store it in Database $timer = md5(time()); $sid = $UserID . + . $timer; SetCookie(Cookiename,$sid,time()+2592000); file://Set Cookie for 30 days $query = update members set sid=\$timer\ where UserID=\$UserID\; I set the cookie with the user id and a Session ID I create... then when it checks the cookie it just does $sidarray = explode(+, $Cookiename); $query = select * from members where UserID = \$sidarray[0]\ and sid = \$sidarray[1]\; So using this script you could put whatever else you wanted in the cookie. You would just change $sid = $UserID . + . $timer; to $sid = $UserID . + . $timer . + . $email; for example. Then when you do $sidarray = explode(+, $Cookiename); You would have $sidarray[0] = $UserID $sidarray[1] = $timer $sidarray[2] = $email You could continue adding additional variables (or plain strings for that matter) in this manner. The only thing to keep in mind is that cookies have a 4K file size limitation and anything beyond 4K will be lost. Check under additional notes on this page for details on cookie limitations http://www.netscape.com/newsref/std/cookie_spec.html I hope all that is clear.

This was accually what I was looking for, but gave up since the other tutorials and script examples where too complicated for me to grasp. One question to the code on the site: Is it possible to insert info to be grabbed on other sites? Like email password name So you can grab like name, instead of having to querity the DB all the time you need the name of the person and so on? And if yes, how do you get it from the cookie and insert it into the page like $name ?

Re: [PHP-DB] Member authentication with PHP and MySQL
My Script uses a Session ID Variable when verifying the user
You don't have a field setup for this. So either change the code
in this section
$timer = md5(time());
$sid = $email . + . $timer;
SetCookie(ElectrocutedClanRemains,$sid,time()+2592000);
$query = update members set sid=\$timer\ where email=\$email\;
or Add to your DB
sid char(32)
(md5 always returns a 32 character long string)

Re: [PHP-DB] Attachment
I have actually done several projects with different kinds or e-mailing features. In a nutshell, you need the appropriate MIME headers for the type of mail, and sections of body divided by MIME Boundaries. (You also need to encode any files you are sending as attachments. Check the base64_encode function at php.net for this) RFC1341 and the revised version: RFC1521 give you all the specifics you need to do this in almost any situation. I would suggest skimming through 1521, paying special attention to the section on Multipart/Mixed (as that is what you would usually use for an e-mail with attachments) I would also suggest sending yourself a couple of e-mails with attachments, and then telneting to your mail server and viewing them there. Doing this has probably helped more more than anything when working on a complex mail program. Don't reinvent the wheel, see how the other guys made theirs =P If you have any specific questions let me know.
