[PHP] ecommerce related question
Firstly, not really a php question, but generic web stuff, but I feel it's still better answered here. Recently a friend came to me asking to create an ecommerce website. In the past my php work has been primarily a hobby, and as such haven't really taken much interest or effort into security aspects of it. Given the nature of the project, I realise security is a must. My question is: what recommended reading for security or ecommerce can any of you suggest? -- Thanks, Travis Moore tra...@live.com OR trabus2...@gmail.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] GD - JPEG to PNG with transparency and color
Following files:
bg.png - Clear Transparent Image
14416fed5d4f78.jpg - Normal Jpeg Image
The Code:
header('content-type: image/png');
$watermark = imagecreatefromjpeg('14416fed5d4f78.jpg');
$watermark_width = imagesx($watermark);
$watermark_height = imagesy($watermark);
$image = imagecreatetruecolor($watermark_width, $watermark_height);
$image = imagecreatefrompng('bg.png');
$size = getimagesize('bg.png');
$dest_x = $size[0] - $watermark_width - 5;
$dest_y = $size[1] - $watermark_height - 5;
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0,
$watermark_width, $watermark_height, 100);
imagepng($image);
imagedestroy($image);
imagedestroy($watermark);
The Problem:
The code above works fine in sense of syntax! bg.png acts as a
transparent border for 14416fed5d4f78.jpg to keep the size of bg.png and
not the size of 14416fed5d4f78.jpg so it doesn't blow up
14416fed5d4f78.jpg. However, the image comes out black/white and has
lost its color!
I looked all over Google and I've found nothing so far that's functional
to give the new created png file the correct colors as the original
14416fed5d4f78.jpg. I figure that I'm missing some small elements to the
process of creating the png...
Anyone have any ideas, pointers, advice, or correct solution to make
this possible?

Is that the way to do it?
Hmm.. Maybe I sent you in the wrong direction - I can't find any docs on
using setAttribute to set the fetch mode. Anyway, setAttribute always works
like this:
setAttribute(attribute_to_set,value_to_set_to);
I was expecting something like:
setAttribute(PDO::FETCH_MODE, PDO::FETCH_ASSOC);
I don't think that works though, can't find anything in docs relating to
attribute called FETCH_MODE. Anyway I dug in some code and this is what you
can do:
foreach ($pdo->query($query, PDO::FETCH_ASSOC)) {}
Query can take a second parameter.
Another option:
PDOStatement->setFetchMode(PDO::FETCH_ASSOC).. so your original code goes
from:
foreach ($pdo->query($query) as $row) {}
To:
$statement = $pdo->query($query);
$statement->setFetchMode(PDO::FETCH_ASSOC);
foreach( $statement as $row) {}
There must be a way to set it with setAttribute for the connection though,
instead of just on a per-statement basis...

Not sure if you can get your logic in up the stream though before it gets to you. If you can you never have to deal with bounce messages and the entire queuing process that goes along with it, mail server maintenance, etc.. Bounce to the enveloper sender, not the "From" header. I also believe bounces are supposed to have an envelope sender of "<>" to avoid bounce loops... not sure on that though.

[PHP] preg_replace and regular expressions.
Okay, so what I have is a BB code type of thing for a CMS, which I for
obvious reasons can't allow HTML.
Here's the snippet of my function:
function bbCode($str)
{
$db = new _Mysql;
$strOld = $str;
$strNew = $str;
$getRegexs = $db->query("SELECT `regex`,`replace`,`search` FROM
`_bb_codes`");
while ($getRegex = mysql_fetch_assoc($getRegexs))
{
$search = base64_decode($getRegex['search']);
$regex = base64_decode($getRegex['regex']);
$replace = base64_decode($getRegex['replace']);
if (preg_match($search,$strNew) == 1)
{
for ($i = 1; $i < 20; $i++)
{
$strNew = $strOld;
$strNew = preg_replace($regex,$replace,$strNew);
if ($strNew == $strOld)
{
break;
}
else
{
$strOld = $strNew;
}
}
}
}
$return = $strNew;
return $return;
}
**
But, for something like this:
[quote][quote]Quote #2[/quote]Quote #1[/quote]No quote.
I'll get:
[quote]Quote #2[/quote]Quote #1
No quote.
Despite being in the loop.
Regex is: /\[quote\]((.*|\n)*)\[\/quote\]/
Replace is: $1
Both are stored base64 encoded in a database.
Any help / suggestions much appreciated.

Basically you cram whatever info you want into the 'unused' or 'less used' bytes of the image. With this in mind I imagine even if you did have an image repository of only 8 images you could add some random bytes to the right spots in the image without distorting it beyond recognition/corrupting it, and therefore get a hybrid of static/on-the-fly images, that hashing couldn't break so simply. 2 cents...

Never touch credit card numbers. You can't just take credit card numbers and manually process them in 'card not present' transactions (or MOTO in more archaic terms.) You need a merchant account that allows for this -- usually at a higher discount rate. Check the merchant agreement. Your client should get an account like this, or better yet, provide you with the instructions on how to integrate his site with the payment providers so that you never have to worry about credit cards. As an additional note... Maybe your SSL cert secures the numbers from the client to the server, and just maybe your PHP scripts have no security flaws in them, but you must remember the server itself and everything else outside of PHP. What if someone found a flaw in the FTP server for example, or the mail server even, and used that to get the CC info. I would hate to be explaining to a list of 1000 clients that I was responsible for their card numbers being stolen.

Use date("Y-m-d",$epochtime); to get a standard date string out of it.

I still wouldn't go around telling people to re-write all of their code to use for loops instead of while loops (or whatever was faster for whatever architecture.) Keep in mind that .000xx seconds in performance improvement certainly does make a difference on a site that is accessed millions of times a day, however, one bug caused by writing code that reads poorly instead of writing clean code can cost a *lot* more in the end. - Use what reads easier when deciding if a for/while loop is best. - Profile your code and find the right places to optimize. Optimizing code that takes .0001 seconds to run down to .1 seconds is great, 10x improvement! Who cares. Find the chunk that takes 0.5 seconds to run and optimize that to 0.05 seconds. 10x improvement still, except that this time it actually makes a practical difference.

This has been asked many times, probably likewise for every language.
Search for the same question on the C programming language for a more in
depth discussion of this and to find out why one way is faster than the
other...
Major factor: Don't forget the difference between pre and post increment
operators. $i++ and ++$i.
For reference this is my PHP test script and results:
{{{
[EMAIL PROTECTED] tdoherty $ cat ./forwhile.php
[EMAIL PROTECTED] tdoherty $ php ./forwhile.php
For pre-increment (10): 0.035
For post-increment (10): 0.060
While pre-increment (10): 0.029
While post-increment (11): 0.056
}}}
After multiple runs I see that the for pre-increment loop is fastest.
Note that the while loop with a post-increment runs once more than with
a pre-increment.
Everytime I run, the results are *very* different, though still fall
within similar comparitive domains.

It's kind of weird to pass sessions through URLs though, I prefer clean, simple URLs such as www.example.com/resource/topic.html, instead of something like www.example.com/?x=resource&y=1113&this=44&PHPSESSID=123124124124124&bookmarkable=not_really Travis -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Just a note that while SSL may help to protect the session id from being packet sniffed you should still be concerned about storing sensitive data in _SESSION. Anyone local to the system can probably read plaintext session data from the session cache. HTTPS only protects communications between the client and the server at best, do be afraid!

By default the session cookie expires when the browser is closed. You can change this by changing ini setting session.cookie_lifetime to something other than default value of zero, in number of seconds. I don't believe using HTTPS changes any of this, I have more than one app that use HTTPS for session cookies and have no problems with it persisting after the browser is closed (well, some browsers can do weird things sometimes... you never really know.) If the browser refuses the cookie, sessions won't work anyway. The session key is sent to the browser as a cookie (unless its in the URL...) www.php.net/session/ Take a look at cookie_lifetime and you might like the cache_expire docs on the same page too.

Have you tried to just put the username and password in the URL? I'm
not sure if this works, its so simple its worth a try. Instead of using
(whatever function you use) like the first example try changing it like
the second:
x('http://example.com/protected/page.php');
x('http://username:[EMAIL PROTECTED]/protected/page.php');
Of course it depends on the 'x' you are using... I'm really not sure if
PHP's functions will take care of moving that username/password
information into the header of the HTTP request or just leave it there.

[PHP] Filtering _REQUEST.. Why is this bad?
Hello.
Came across some code that startled me. Mostly because it goes against
the generally accepted idea of detecting and rejecting bad input instead
of trying to escape it, secondly because "it just feels wrong."
The only technical case I have so far is for inserting a double/single
quote into the database. It will get inserted as its htmlentities equiv
of '"' for example. In the future if they wanted to display the
data in the database in a format other than html it will be messy.
So... the question is: What else is wrong with this? or.. Why is this so
bad?
$val)
{
if (is_array($val))
{
$return[$key]= recursiveFilter($val);
} else {
$return[$key] = htmlentities($val,ENT_QUOTES);
}
}
return $return;
}
$_REQUEST= recursiveFilter($_REQUEST);
// queries directly inserting from $_REQUEST
// echo'ing of data directly from $_REQUEST
?>

As long as we're clear that it can't touch the filesystem of the user of the application :D If you just wanted to make a list of folders and let them select one you could build the list using an HTML SELECT box. Once they have selected an item and click on submit, you would use similar code that you used to populate your directory list to show a list of all files in that directory. The code at Example 2 on the php.net readdir documentation is probably one good place to start: http://www.php.net/readdir A hint from another thread today to save yourself trouble: Always use full paths when working with files.

In any database that you store timestamps and need to know exactly what that timestamp means you should use UTC, then use application logic to translate to the users time zone. Another option would be to store epoch time (seconds since the OS's epoch) and work the same result from that, I prefer storing human-readable timestamps even if you have to do the datemath in your head to read them in your own timezone. Epoch does not count leap-seconds like UTC so it can be off by a tiny bit at any given time. Epoch time also differs on different operating systems - Unix is 1970-01-01 at 00:00:00 UTC, Windows seems to use 1601-01-01 at 00:00:00 UTC... I don't know if that would ever matter though - I imagine the database server would mask this and the application would port to windows without problems (no idea.) UTC has no DST from: http://en.wikipedia.org/wiki/Time_zone >> Due to daylight saving time, UTC is local time at the Royal Observatory, Greenwich <http://en.wikipedia.org/wiki/Royal_Observatory%2C_Greenwich> only between 01:00 UTC on the last Sunday in October and 01:00 UTC on the last Sunday in March.

Yeah... I ran into the same stuff a few weeks ago with the DST change.
The quickest solution that is *almost* OK is using
putenv("tz=america/montreal") or putenv("tz=america/san_diego") etc..
(should really be the date_default_timezone_get/set functions)
Datetime fields do not have timezone stored (mysql too.) The only real
solution to this problem is to always store datetimes in GMT/UTC. That
is the correct thing to do, and until that is done our workaround still
has one problem (that isn't big enough to warrant reworking the
ticketing code that inserts to the db...)
The remaining problem is that until we store in UTC we will never know
which 01:30:00 a timestamp refers to, EDT or EST (Eastern Daylight, or
Eastern Standard.) In UTC this doesn't happen. Of course there is no
problem for spring, only in the fall time change.
This can be a big problem to some apps, and others might be fine with
the workaround like we've done where you loose a tiny bit of data (It's
08:00 on the day after the timechange, is this ticket from 01:30:00 6.5
or 7.5 hours old? who cares.. just reply.)

I think it would be easier to ask the user to enter his reminder in the
standard date format of -mm-dd and use a JavaScript date picker box
to prompt for it. Anyway, you could do something like this:
$reminderStamp = strtotime("+{$addMonths} months",time());
$reminderStamp = strtoTime("+{$addDays} days",$reminderStamp);
$date = date("Y-m-d",$reminderStamp);
$date should have a string like -mm-dd that is $addMonths and
$addDays into the future. I didn't test this.

Yup, as you mentioned the AWL (auto-white-list) is a comparison to previous messages. If that is the only rule that gets hit it looks like you are doing pretty good. You did include the body of the message in the test right? Not just the headers? I expected you would have hit more rules than that. Of course, that is an 'out-of-the-box' install of SA, most people have special rules in there, bayes training done, etc... I believe there is also a website that you can copy paste the message into to perform the same test (see message on this list, "Peter Lauri - PHP Mailer and SMTP = SPAM?") That site might have other rules configured (SARE... etc) that you might be hitting. Worth a shot.

If it is sendmail it would be the -f parameter to set the Envelope-From
address. ie... php.ini would have 'sendmail_path = /pathto/sendmail -f
[EMAIL PROTECTED]'. Since PHP 4.0.5 you can also set the
additional_parameter like php.net/manual/function.mail.php (the example
there is specifically for this use.)
What you actually should be doing: install SpamAssasin on your
workstation and run the message through it in test mode... Figure out
what rules get hit and work to resolve those. Run it like `spamassassin
-t < message_with_headers`
So, you'd copy your complete message (as you have above) into
message_with_headers and run it through SA. Maybe SA is giving you
points for things like too many exclamations, certain ratio of HTML...
I doubt that having a return-path of 'nobody' is the lowest-hanging
fruit you can pick up here to make yourself look less spammy.
Also make sure the sending mail server isn't listed in any blacklists
(yahoo for RBL lookup tool to check.)

If the error is 'Undefined function mysql_connect' then you do need to get MySQL support compiled in... If it is available on the apache module it should be available to the CLI as well.

Try to get the error message from the DB Connection when it stops.
If MySQL something like this (from the PHP Manual for mysql_connect)
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}

Richard is correct on that. The fifth argument isn't only for the

They should *always* be sending to the envelope from address (SMTP `MAIL

avoid loops.

Is it a UNIX box? Sendmail takes the -f parameter in your php.ini to configure
its envelope from address... Does not extract it from message headers. The
fifth argument to mail() also supports doing this if you need to change it on a
per-mail basis. I would just set it in php.ini. (like: sendmail_path =
'/usr/bin/sendmail -f [EMAIL PROTECTED]')
If its a Win box there is a sendmail_from config param in php.ini.
php.net/manual/function.mail.php read for 'Additional Params' the fifth
argument, it specifically deals with this case.

Most Linux boxen have `|/usr/share/zoneinfo/zone.tab`, or grab it from
the database tables in a mysql server (assuming it is setup with
timezones imported) which would be the mysql.timezone* tables.
|http://www.php.net/putenv
The comments have quite a bit on timezones and PHP. The command you
will use to change the timezone of the running script is:
putenv("TZ=$zone");
The equiv to set a MySQL connection to a certain timezone would be:
SET time_zone = '$zone';
http://dev.mysql.com/doc/refman/5.1/en/time-zone-support.html
That URL has the MySQL side of setting timezones.

I use the DATETIME fieldtypes in MySQL, same idea... 100% agreed that
keeping that timestamp for later use is a good idea.
For Kevin's original question.. Here is the MySQL function to get that
short weekday name off of a DATETIME column:
Table with datetime column:
mysql> SELECT id,effectivetime
-> FROM event
-> WHERE employee_id ='1001';
+-+-+
| id | effectivetime |
+-+-+
| 184 | 2006-09-18 18:50:25 |
| 182 | 2006-09-17 23:12:17 |
| 178 | 2006-09-12 21:59:44 |
+-+-+
3 rows in set (0.00 sec)
Query to get 'weekday':
mysql> SELECT id,effectivetime,DATE_FORMAT(effectivetime,"%a") AS weekday
-> FROM event
-> WHERE employee_id = '1001';
+-+-+-+
| id | effectivetime | weekday |
+-+-+-+
| 184 | 2006-09-18 18:50:25 | Mon |
| 182 | 2006-09-17 23:12:17 | Sun |
| 178 | 2006-09-12 21:59:44 | Tue |
+-+-+-+
3 rows in set (0.00 sec)
Those DATETIME columns can do some other neat things too:
SELECT * FROM events WHERE starttime BETWEEN '2006-09-18' AND '2006-09-28'
Gives me a list of events happening in a certain period...
SELECT * FROM events WHERE DATE_SUB(CURDATE(), INTERVAL 30 DAY) < starttime
Gets you the last 30 days without needing to make those '2006-09-18'
style strings in PHP code.
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html
They should all work on DATETIME type columns, storing seconds since
epoch doesn't quite give you that (you could work it in pretty easily
I'm sure, why not use the native column type!)

Travis

If you don't set a subject line, SpamAssassin hits you hard, make sure you have a real To:, From:, and Subject: header. The date header also needs to be set - with the correct time. Spam scores come from many different sources of information - two major sources are the message itself and the server sending the message. If you can send mail from this server using a normal mail client and it does not get blocked as spam then it is probably your message. If sending using a normal client still gets blocked as spam in you gmail account chances are it is the server and not your code.

You could go the script route as you have mentioned and also add a check on HTTP_REFERER to ensure they came from your site. You might even set a cookie and ensure that exists as well. Randomize the image numbers so they are not sequential, add some alpha characters to make it real fun. Give a 404 Not Found instead of an error if the referer or cookie wasn't set to add some obscurity to the mix. This will deter most people from grabbing all of the images, but if they are available to the public for download it will always be possible for someone to figure out your counter measures.

There is still an error in that code (missing comma) and the error
message also has an unmatched quote.
The actual error message seems clear "No such file or directory" - does
"home/path/temp" exist, did you mean "/home/path/temp".

Re: [PHP] GMT
Here has always been a problem I run into with GMT translation. You have to make sure that the system you are working with is set to the correct time zone so that any application trying to automatically figure out the time have the starting point. This is easy enough in Windows, but can mean making sure your /etc/localtime (See http://www.linuxforum.com/linux_tutorials/68/1.php) is correct in linux. Of course there are GUI tools to help with this also for those non-console people. Unfortunately some people rely on shared servers where you do not have root access to change /etc/localtime. Therefore you must have an overloadable function to return the time in GMT. Where it can accept an offset or rely on the systems timezone. To me, it seems best to just use a variable. Print out the time, then do a correct offset for it.

I was working with the mail function today to experiment with sending
a few messages, and threw in the apropriate checks so when mail()
can't send the message the apropriate errors were raised, however, I
discovered I couldn't actually get mail() to return 0. Take the
following call:
mail("dude", "Daily Feed Update", "body");
I assume "dude" is a local user you are mailing to? Make sure you also give
a FROM address. Try this:
mail("[EMAIL PROTECTED]", "Daily Feed Update", "body", "From:
[EMAIL PROTECTED]")
-Trav
When I run that exact call (well, I prepend echo, but you get the

would accept an email with a destination of 'dude'.

I think you're looking for "argv": http://www.php.net/manual/en/reserved.variables.php#reserved.variables.server PS Btw, it's "php-geNeral" and not "php-geMeral" ;) It is much easier to just ask you guys though.

How do you reference command line arguments in php? i.e., chkmd5.php file.md5 I am wanting to reference file.md5.

Subject: [PHP] For Loop
I have a question about the following code:
**
$months_arr = array("JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL",
"AUG",
"SEP", "OCT", "NOV", "DEC");
$months_arr_length = count($months_arr);
for($i = 0; $i = $months_arr_length; $i++){
echo $months_arr[1]." ";
}
***
When I run the code above it continues and never stops. According to the
PHP
documentation the second condition works as follows:
"In the beginning of each iteration, expr2 is evaluated. If it evaluates
to
TRUE, the loop continues and the nested statement(s) are executed. If it
evaluates to FALSE, the execution of the loop ends."
In the first iteration of the loop $i would equal 0 and the array length
is
12. 12 is consistent. To it seems that the loop should STOP when the
counter
reaches 12, equal to the length of the array. Why is it continuing in a
neverending loop? What am I missing?
Changing the condition of the for loop to $i <= $months_arr_length; fixes
everything and it works properly.
Can someone please explain where my confusion is?
Thanks,
~R. Van Tassel

Re: [PHP] mysql error
Try: SELECT * FROM listing WHERE listing.state = 'WA' AND listing.type = 'RES' AND listing.county = 'clark' AND (listing.price > 15 OR listing.price <=20) Try to not use the word "type". Do not know what it is but I have some problems using it. In the event you have weird problems, try putting the table name before the field like I did (i.e., listing.type). You probably also need the price in params since you want to OR just on those two items. I also assume that you have the price field as a int, bigint, or similar field type which does not require a tick around the value. I also dont think that the back tick works.

Depends on what you wish to do with php. PHP 5 has far better support for xml and soap than php 4. It has a stricter object model and supports native exceptions for error handling. Iterators, reflection, and __call()/__get()/__set() provide incredibly flexibility. It is new, and so not nearly as stable as PHP 4. Any solutions would need to be custom-written for PHP 5 at this point, although options are beginning to appear. PHP 4 has a big history and is very stable. There are shortcomings that are addressed in PHP 5, but there is a huge codebase. So, the question is, do you rely on other people's code, or your own?

[PHP] Mass MySQL INSERT
I am fairly new to the concept of working wity mysql and php. I am looping
thru a text file full of county names and attempting to add these to a database.
Now the table exists and if I enter the SQL statement manually against the
database it works. The user also has read and write permissions to the table
and the columns in the table.
Here is my php code:
$lines = file("/tmp/new1.txt");
foreach ($lines as $line_num => $line) {
echo($line . '... ');
$link = mysql_connect('naabe', 'naabe', 'x')
or die('could not connect: ' . mysql_error());
// I use substr to remove the space at the end of every line.
$sql = "INSERT INTO countries (country) VALUES ('" .
substr($line,0,strlen($line)-1) . "')";
echo ($sql . ' ...');
mysql_query($sql);
mysql_close();
flush();
}
This is how I configured php4.3.9
./configure --enable-so --with-mysql=/usr/local/mysql --enable-filepro
--with-apx2=/usr/local/apache2/bin/apxs --with-jpg --with-png --with-xml
It will print to the screen the line and the SQL statement correctly. The
password is correct. The database name is naabe, the user is naabe.
Anyone know what I could be doing wrong?

I have designed and successfully prototyped a native Windows binding for PHP. This binding is already capable of doing dialogs, controls, and a lot more with very few lines of code.

After STFW, I've not found any good documentation on it, just the short
samples on http://www.cpanel.net/remoteaccess-php.html
I haven't found anything more detailed on their site. I just ended up looking
at the scripts themselves. They are just wrappers around the scripts that are
part of the cpanel installation. If you find more documentation, I'd love to
know about it.
At this moment, I have access to some servers with the accounting libs
installed, but I have no access to the fonts (Which could help to make
it work).
I didn't have to do anything with the fonts. What problems are you having?
If anyone can post a link where to find good docs about this cpanel lib,
and, if possible the source code for it, it will help me so much.
Here's a snippet:
# cpanel idiotically outputs html rather than
# programmatically-useful error codes. Thus, we have to manipluate
# the output before and after calling cpanel function.
flush();
ob_start();
# You can get the $cpkey from the WHM. The rest are yours to fill in.
createacct( "localhost", "root", $cpkey, 0, $domain, $acctuser, $acctpass,
"packagename" );
ob_end_clean();
# Now we check after the fact to see if account was created.
# This is a VERY WEAK test, needs improvement.
$accounts = listaccts( "localhost", "root", $cpkey , 0);
$keys = array_keys( $accounts );
$account_found = NULL;
for( $i = 0; $i < count( $keys ); $i++ )
{
if( in_array( $domain, $accounts[$keys[$i]] ) )
{
$account_found = TRUE;
break;
}
}
There are a few gotchas with this API. For one thing, createacct() always
returns the string "Account Creation Complete" no matter if the account was
created or not. You have to verify the creation some other way.
For another thing, the createacct() function writes directly to the output
stream. So all of the stuff you see when you create an account the normal way
(using the Cpanel web interface) will be displayed unless you stop it. That's
what the flush() and the ob_* stuff does.
If you find more information, that would be great. We can trade notes.

[PHP] Re: SuExec and PHP
I sent this a couple days ago and haven't heard a peep. Can anyone help me? Or, is there a better place I could be asking these questions? cheers, Travis Travis Low wrote: Greetings.

Re: [PHP] md5() with rand() || Strange results, need help....
Besides checking the browser cookie settings, have one of the affected users turn off the auto-fill form feature, then tell the browser to forget all saved form information. Let us know what happens. cheers, Travis CF High wrote: Re: the browser track, it looks like all adversely affected users; i.e. those who can no longer log in, have a browser of I.E. 6.0.

Re: [PHP] PHP5 - instanceof
An instance only exists after it has been instantiated. So you can't know anything about an instance (== an object) beforehand. It's like knowing a person before they are born. Maybe you mean you want to determine if class B is a subclass of class A. That's the same problem again. Even if PHP5 had a Class object (a la Java), you'd have to instantiate *it* in order to find the relationship between class A and class B. Prior to that point, you only have text strings to work with. I suppose you could search the text of the file for "extends FooBar" or something. cheers, Travis Martin Towell wrote: I have been playing with PHP5 and am liking it more and more. But I have one question about "instanceof" If you have something like this: This would echo "BA". That's good, I understand that. Now the question: Is it possible to determine if B is an instance of A without instantiating it?

There is _no way_ to really hide/protect html page on client side.. If someone (some knowing) would like to show your source and it's important for him, then he spend some time to break this ugly protection. Just to strengthen/clarify this statement, look at it this way. The user has downloaded the data to his machine. You don't have any control over the data after that point. Heck, the user can just print the screen they are looking at. How you gonna stop that? If you're just looking to discourage casual copying, then carry on. :-) If it's really important, you might be able to generate non-printable PDF files, or generate images containing the desired text, or stuff like that. Just to make copying/printing harder. cheers, Travis -- Travis Low <mailto:[EMAIL PROTECTED]> <http://www.dawnstar.com> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Profiling (Was: Re: [PHP] PHP Website Architecture)
Hi Richard, Just curious...how do you do your profiling? cheers, Travis Richard Davey wrote: Hello Ryan, Friday, May 7, 2004, 4:51:45 PM, you wrote: RA> Nearly all programs can be written in *one* very large .php file but just RA> thinking of going back in to make changes 3 months down the road would be a RA> nightmare. I was just looking at this the other day - I had a local site running here and profiling the index page took around 800ms with 30 include files. Out of interest I dumped a load of those files into one and re-profiled it (11 includes rather than 300) and the load time dropped dramatically (300ms). I know there are other factors at play here (Windows vs. Unix, cached vs. needing to seek across the hard drive every time), but the difference still surprised me. Of course I could never cope with all of those files "as one", but I will definitely keep them split up locally and combine into one when published live. -- Travis Low <mailto:[EMAIL PROTECTED]> <http://www.dawnstar.com> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] A work around my HTTP_REFERER Prob...
How about something like this:
Write a script on server 1 to accept "username" and "password" parameters. If
successful, it echoes "1", if not, it echoes "0".
On server 2, you do something like this:
$s = file("http://server1?login.php?username=$username&password=$password";);
if ($s[0])
{
# User is logged in.
}
You can also write the script on server1 so that it only returns 1 if the
request came from server2.
Disclaimer: I know this scheme isn't airtight, but it beats relying on the referer.
cheers,
Travis

To recap...
We have two servers:
1. USA - holds most of our databases, and E-mail. but specifically, the
usernames and passwords, or all our users (Lotus Domino Server)
2. UK - Runs our website. (Unix Server)
We wanted to be able to allow people to login on on server 1, and getr
authenticated etc, and then get redirected to server 2.
Using http_referer we would confirm that they came from server 1
However, as I discovered, that is not possible.
So what we did was this:
On the login form on server 1, the referering URL to server 2, contains a
varibale called 'secure'
we asign that variable that value of '4654376534' and divide it by the day
(eg: if it's the 12th of may, we divide by 12.. 7th of June, we divide by
7)
I know that this is crackable, but it's just a stop gap measure...
My problem today is this:
It's not confirming the values?
See my code below
session_start();
$today_day = date("d");
$code1 = ($today_day+1) * $secure;
$code2 = $today_day * $secure;
$code3 = ($today_day-1) * $secure;
$master_code = 4654376534;
if (($code1 == $master_code) || ($code2 == $master_code) || ($code3 ==
$master_code)) {
$_SESSION[logged] = 'true';
$login_info = "You are now Logged in";
} else if ($_SESSION[logged] == 'true') {
$login_info = "You are still Logged in";
}
=
I start by getting the date $today_day
As we're in two time zones, I don't wanna get caught out by the time
difference, so I've created a +/- 1 each side ($code1-3)
and fianlly, asigned the master input variable (the decoder)
Now it all works great..! (all variables echo what they should) however,
I'm not getting logged in?
I'm really stumped...
any ideas?
Tris...
