Either the ANSI standard changed, or Rasmus needs to update his Bio...

http://lerdorf.com/bio.php

"...he can be blamed for the ANSI92 SQL-defying LIMIT clause in mSQL 1.x
which has now, at least conceptually, crept into both MySQL and
PostgreSQL."

But, hey, I'm not gonna actually READ the ANSI standard to find out -- I'd
rather worry about what actually *WORKS* than what the SQL standard is,
which, sadly, is seldom easily reconciled with Real-Life (tm).

[PHP] SSL use

[ruel.cima]

 hi,

 im handling some important information that needs to be stored in my
 postgresql database via a php script. i´ve been reading the mails sent on
 this mailing list on SSL use. my postgresql server allows SSL connections
 but im not sure how to make use of this.id like to know more about ssl and
 how to take advantage of its security features. any references?

  from my php script, do i need to make a special connection to the database
 or is the same e.g pg_connect(host= localhost dbname=test user=p
 password=p)?

 is my information automatically transfered in an encrypted fashion?

Look at array_pop and array_push and count and array_slice and

[PHP] PHP cron sendmail

[Richard Lynch]

Somewhat OT...

Okay, maybe a lot OT...

I have these cron jobs on a computer, and I want the email output from them.

But I don't want sendmail running 24/7, and when it does run, I'd just as
soon it *ONLY* processed email and sent it out, without even opening up
port 25 and listening.

I guess the port 25 stuff is not too terribly important, behind 2
firewalls and all, but...

Anyway, I definitely want it to run and process however much it can, but
to STOP at a pre-determined time.

This is for the computer in my sound booth, and I only want it running
when we are not trying to record live music or burn CDs.

I've Google and read a fair amount of stuff, most of which is giving me a
headache rather than suggesting a solution...

Is there some command line flags I can use to make sendmail run and send
out just *ONE* message from the /var/mail/mqueue or whatever, and then
QUIT and do nothing else?

I can take care of shaping the behaviour from that point using cron and
PHP to run sendmail when I want...

THANKS and please reply off-list as I'm sure most folks don't want to read

Because you have two different versions of PHP installed. In
otherwords, the CGI version and most likely the module
version.

Now to answer your question, here's a quote from the 
PHP Manual:

 Note: Prior to PHP 4.3.0, $_FILES information was 
   also included in $_REQUEST.

So, $_FILES is no longer part of $_REQUEST.

I took it at the "2005 PHP Quebec Conference" (it was part of the fee).

You'll likely have better luck, as I normally don't do well with exams 
in general.

As an aside, I think the exam needs to mature a bit more. I was confused 
a few times, and found a few questions that involved cases I had 
certainly experienced in five plus years of PHP development. I'm sure 
that'll happen in due time as the certification is only a couple years old.

That was the first thing I tried, and it doesn't seem to work (it always

you can do with fwrite. Did you actually test that before you replied, and 
found that it would? If so, how? The Byte Order Mark is a part of the binary 
file that is written, how would one go about stripping it out??

BTW, note to PHP developers: If "fwrite" had a "encoding" parameter, e.g. 
"UTF-8", that would be REALLY handy. 
Strings in PHP are binary-safe and character-encoding neutral.  fwrite 
doesn't have a clue what it is writing, it just writes what is in memory.

I'd question why you would want to strip the BOM.  Any modern system 
deals with the byte-order-mark correctly.  But you can simply strip it 
manually if it is present in the first 2 bytes before your fwrite if you 
really need to get rid of it.

It's a "constant initializer" - which is both an accurate and

be constant through-out your entire class (meaning any method can
access it) but unlike true PHP constants (those created with define)
the value of the variable can be manipulated from just about anywhere.

indeed in php you can do the following instead:

error_reporting( E_ALL & E_STRICT );
class Test
{
// this first var (commented out) should (I thought) act as if defined
// 'public' - it doesn't given a parse error with php -l, but does when run.

// thats only available from within _all_ methods of this object.
static protected $myVar7 = "7";
// a variable with class scope (all instances see the same value),
// thats only available from methods defined in _this_ class
static private $myVar8 = "8";
public function get4() { return $this->myVar4; }
public function get8() { return self::$myVar8; }
}
// basic usage examples:
var_dump( ($t = new Test), $t->myVar2, $t->get4(), Test::$myVar6, $t->get8() );
?>
I can thoroughly recommend php5's much improved object model,
try other variations of calls to the defined 'myVar's, also try doing
with sublcasses, see what does/doesn't work, have fun :-)
It is of course PHP4 only and is depreciated in PHP5.

Probably not; I was simply discussing the mechanism in general.  If
the only users who could sniff the connection are privileged users
who already have access to the filesystem and memory, then encrypting
a connection to localhost wouldn't do much except slow down the
connection.  It would, however, mean you wouldn't have to remember
to change that later if the web server and database were split onto
separate machines.

> Is it possible to make an SSL connection between

I don't think libpq will attempt SSL over a Unix-domain socket.  I
see a comment in fe-connect.c that says "Don't bother requesting
SSL over a Unix socket", although I haven't examined the code to
see if that's the only place such a decision would be made.

BTW, connecting with "host=localhost" makes a TCP connection;
omitting that and making a Unix-domain connection would probably
make the connection more efficient (assuming the system supports
Unix-domain sockets, that is).

Re: [PHP] modify array data

[Brent Baisley]

Well, it's just a matter of coming up with the formula for converting 
your data. I briefly tried to come up with one, but gave up after I 
realized there would not be a "center" data piece if you have a 4x4 
array or any even number array for that matter.
I would right down the array positions for before and after and try to 
find the pattern you are looking for. It should be some combination or 
rows, columns and array size (addition, subtraction, multiplicaiton, 
division, absolute values, etc.). If you can't find the pattern, you 
can't write a generic conversion function and neither can PHP or 
anybody.

Your first row maps like this (row,col):
0,0 -> 2,0
0,1 -> 1,1
0,2 -> 0,2
This formula would map the first row appropriately:
row = ColCount - ColNum
col = ColNum
It obviously fails for your second row, but it's just an example.
There is obviously a pattern which the mind can interpret fairly 
quickly. But trying to describe it in exact terms can be difficult.

The rest of the error message should be telling you what PHP is using for
include_path.

Does that match what you expect?

If not, then you don't have php.ini the way it should be.  Check the
location of php.ini in 

If it *does* match, then maybe your Pager.php file is messed up and the
class is missing a closing bracket, so your script thinks you're still in
the middle of your class definition.

check that using phpinfo() function, it is showing as PHP 4.2.2. Why
the difference? I am working in that view to find the solution.

MD5 is hashing which is not the same as encryption.  Hashing is 
normally defined as a one-way conversion of a plaintext message into a 
fixed-length digest or "hash".  Encryption is normally defined as 
conversion of a plaintext message into ciphertext which cannot be read 
until it is decrypted -- i.e. encryption normally implies the 
possibility of decryption.

In that framework there is no such thing as "decrypting" an MD5 digest, 
because an MD5 digest is not an encrypted version of the message to 
start with.  No amount of CPU power will change this basic fact -- 
though CPU power can be used to do a brute force search for strings 
which will generate a given MD5 value.  However, as stated before, at 
current levels of computing power this is not feasible for messages 
beyond I think 7 or 8 characters long (don't quote me on that).

The recently discovered "hole" is unrelated to the above.  It is that 
under certain conditions it is possible to find two different plaintext 
messages which will generate the same MD5 digest.  This could 
theoretically allow one to spoof a message and have it appear 
legitimate if MD5 is used for the legitimacy check, but it does not 
allow "reversal" of MD5, nor do the authors of articles on this problem 
seem to claim that it could.

As the User Contributed notes indicate, *SOME* PHP errors simply cannot be

This may, or may not, be one of those cases.

Is an undefined function one of the examples?  If not, try one of those.

Also, did you remember to call http://php.net/set_error_handler as well as

Here is something I have done in the past to speed up php/mysql pages
(should work with other databases though).  Basically, I noticed that
the majority of our database calls were read calls, rather than write
calls.  So, in all of the locations globally, I set up "read-only"
database servers, and also replicated the php code to all of the
sites, then still did all of the writes to the "master" server but,
all of the reads from each local "read-only" server.

Not sure if this is necessairily the "best" way to do things, but it
worked well for me, and sped things up quite a bit.  This does mean
you have 2 database connections always, 1 for reading, and 1 for
writing.

For mysql, look more at their website for how to set up replication
machines.  As far as the code goes, I just have a process that
straight copy's it from my "master" server.

As always Firefox to the rescue.  I find more good tips on web browsing

No.

I got NO IDEA how you would do this in XML.

That was the first thing I tried, and it doesn't seem to work (it always 
saves in windows default encoding). Unless I missing something about what 
you can do with fwrite. Did you actually test that before you replied, and 
found that it would? If so, how? The Byte Order Mark is a part of the binary 
file that is written, how would one go about stripping it out??

BTW, note to PHP developers: If "fwrite" had a "encoding" parameter, e.g. 
"UTF-8", that would be REALLY handy.

In that case, I'd be looking for some kind of conditional around the
require 'Pager.php' that is making it not actually get included at all...

Put print statements right before and after the require line and be sure.

The documentation index has a few entries for "SSL".  Here are some
useful links for 8.0:

http://www.postgresql.org/docs/8.0/interactive/ssl-tcp.html
http://www.postgresql.org/docs/8.0/interactive/libpq.html#LIBPQ-CONNECT

You could add "sslmode=require" to attempt only an SSL connection.

If the connection should always be encrypted, then you could edit
the server's pg_hba.conf and allow only "hostssl" connections.  In
that case you shouldn't need to specify "sslmode=require" when you
connect, although doing so serves as a safety measure against
pg_hba.conf misconfiguration, and as a reminder that the connection
should be encrypted.

> is my information automatically transfered in an encrypted fashion?

Yes, assuming you've successfully negotiated an SSL connection.  To
be sure, you could use a sniffer like tcpdump or ethereal to look
at the traffic.

I have to second Richard on this -- check your php.ini file, and make
sure that the directory where PEAR and/or the PEAR::Pager class are
located are in your include_path. Then, once you are sure of that, make
sure that Pager.php is at the top of one of the paths in your
include_path.

I'm guessing this is probably *not* the case... it's a PEAR package, and
if it's considered stable, this is *highly* unlikely. (Plus, if it's the
stable version, then I'm running it on my production servers, and I
*know* it's working fine!)

But what you could do is create an anonymous account somewhere, let's
say @hotmail.com, and THEN post the name of the company. ;)

Make sure you do this on a computer that allows anonymous access, like,
a friend's house! :)

is there an easy way to do this?
the data and arraysize will vary so I was looking for a way that I could

I believe, then, that you would best be served by focussing your search on
"mirroring" such as that done by, say, http://php.net

Seems to work well for them :-)

I was writing an on-line mapping tool that used PHP and let you outline
the regions for a given image.

Sort of "Indian Jones"-like (the mapping of the plane as he flew)

You'll probably find a nice one, but if not, you may want to consider
writing your own in PHP if the existing ones aren't that good.  It wasn't
that tricky.

Re: [PHP] Php defense

[Joe Harman]

 My 2 Cents > ASP is a Platform that supports a number of different
microsoft languages which includes ASP Javascript, ASP VBScript,
ASP.Net C# & ASP.Net VB ... ASP has a couple of good points to it...
most notably is that it is backed by the largest computer company out
there.. Microsoft... also, from my experience as a college level
instructor, they teach microsoft programming languages at the
colleges... there is nothing spectacular about the programming
languages that ASP supports that cannot be done with PHP... and I
should say that that is my opinion...

I know Yahoo & Google use PHP in some of their applications... also
Lufthansa (Airline) uses PHP... Vonage... Broadvoice.. the list goes

That's exactly my point.

It's similar to how a local root exploit sometimes evolves into a
remote root exploit once publicized and people begin working on it.

Disclaimer: There are only about 5 or 6 people in the entire world who
know anything about encryption.. and sadly I am not one of them.

Re: [PHP] Php defense

As i recall Yahoo uses PHP. Quick Google turned up:
http://public.yahoo.com/~radwin/talks/yahoo-phpcon2002.htm

Also i remember it was a pretty big deal when
Friendster switched to PHP. And the resulting
improvement in performance was pretty dramatic.
O'Reilly has a good article.
http://www.oreillynet.com/pub/wlg/5155

Google around some, especially on the Friendster
switch, which as I recall caused quite a stir, for
more information.

[PHP] Php defense

[Pablo D Marotta]

Hi there..
I`m defending the language, but people here want to migrate to asp..
They just keep on saying "php is not used for huge corporation solutions, there
asp goes better".

I know it isn´t correct, but I don´t know much about "well-known" websites
using php technology. (I just don´t navigate enough time to know it)
I think that could help a lot, since this people is highly influenced by that
kind of facts.. (I mean, knowing that other companies trust this language to
manage critical information).

Does anybody know/have any web-sites listing using php? If you only know a few
of those, it could help me too.

Thanks in advance!!
Pablo

I just googled and came up with a bunch of results:

I haven't had to make any image maps in quite a few years, so I can't

interface will be supported by many of the free utils you'll find on that
first results page.

Nope, if the stream will open and put data into $xml then you're fine.
It's not a requirement that the XML file is on the disk, just that it's
available to memory.

Poly will define any shape you need for the states in an image map.
You'll most likely want to use an image map program to generate it
though so you don't have to map all those coordinates out manually.

This isn't about redundancy, it's about enhancing the experience for
customers physically located thousands of miles away from the server
they are trying to access. So, bring the content closer to them and
drop their wait times massively. It's easy for those of us sat on the

"the Internet is fast enough now that you don't need to do this"), but
in reality that's not really yet the case.

[PHP] Easy question about XML parsing

[Brian Dunning]

I've been going through a number of easy XML parsing examples on the 
web, and they all have one thing in common: the XML is in a file, which 
they read in 4K chunks and parse.

My application will be retrieving the XML from a web service, 
presumably like $xml = file_get_contents($url). I was assuming that I 
could parse the XML in memory using that $xml variable, but since NONE 
of the examples I've seen do this, I was wondering if it's a 
requirement that the XML be in a local file, and needing to do the 4K 
chunk thing.

Re: [PHP] Re: reverse MD5 ???

[Dan Rossi]

I don't think that's right.  Collisions allow certain kinds of
cryptographic attacks against things like MD5-based signatures but that
is not at all the same as being able to simply determine the original
message content from the digest.  Rather, they allow you to substitute
the original message with a different one which generates the same MD5
hash.  This may or may not be useful as an attack, depending on how MD5
is being used.

Anyone ever tried using ENCODE and DECODE functions in mysql ?

Hello Drewcore / Jochem,

Friday, April 22, 2005, 4:45:37 AM, you wrote:

D> are you talking about having one server in south america that acts
D> as your database server, one server in asia that's your web server,
D> and then another server in north america that servers some other
D> task?

Not really - the scenario is more like this:

There is a primary set of servers in the US (one web, one DB, one file
server) - this handles all the "master" content (in English) as well
as the user logins, shop, etc. Content is translated to several
languages which the user can pick from, the site handles this just
fine. This all exists now.

But a vast majority of our customers live in Europe, and smaller but
no less significant sets in Russia and Japan, so duplicating this
content across a set of servers physically located there would be
extremely beneficial for them (speed-wise) where they don't all live
on the end of ADSL/cable connections.

The question originally was the best way to ensure these slaves
provide the exact same content as the master does.

For example one approach could be to sync the content on a file level,
perhaps another is that when the master CMS is updated these changes
are then propagated to the slaves in sequence (i.e. something done
from the PHP code itself rather than on a system level). It's really a
form of load balancing I guess, but application design for this kind
of environment is inherently different to the "all sits on one box"
that most people only have to deal with.

Further digging around has revealed this book on the subject:

"Multi-Tier Application Planning with Php: Practical Guide for Programmers"

(which I've ordered). I also found slides by Theo Schlossnagle from his
Scalable Internet Architecture talk at ApacheCon this year. Both these
things are addressing the design issues I'm now faced with, I'm just
extremely surprised no-one here has encountered them before.

Best regards,

Richard Davey

If this is the best answer your database software will let you come up

Fortunately, the databases that don't do "LIMIT" have this nifty thing
I was under the impression that LIMIT was mySQL specific (although its
quite likely that their use of the keyword and the ubiqitous nature of mySQL

anyway, many other DBs do implement an alternative in the form of FIRST, SKIP

FIRST/SKIP is part of the SQL std)
called "CURSOR" which lets you kind of do the same thing.
At least, all the databases I know of.
Maybe something really stupid and broken like MS Access or something that

Even there, I'll bet there's some better answer than pulling all the rows

I don't think that's right.  Collisions allow certain kinds of 
cryptographic attacks against things like MD5-based signatures but that 
is not at all the same as being able to simply determine the original 
message content from the digest.  Rather, they allow you to substitute 
the original message with a different one which generates the same MD5 
hash.  This may or may not be useful as an attack, depending on how MD5 
is being used.

Actually I think the discussion was about reversing the MD5 to get back 
the original message -- not about cookies or IDs.  What you are 
discussing is a different issue.

Re: [PHP] Sorting table columns dynamically on normalized MySQL tables

[Richard Lynch]

On Wed, April 20, 2005 5:53 am, Leif Gregory said:
> So joining on four tables isn't considered bad practice?

No, it's great practice.

The only thing to watch for is just how *BIG* will the number of tuples grow?

If you can multiply together the number of rows in all four tables and
come up with << 1,000,000 you're fine.

If not, you have to start thinking about how you can get just the ones you
want for each query, and do it in such a way the MySQL never has to cope
with 1,000,000 rows at once.

Actually MySQL is quite happy to do 1,000,000 rows -- It's your hardware
that won't like it. :-)

So it really depends on what's *IN* the data, rather than the actual
number of tables.

Be sure you always get your WHERE clauses right.

One rule of thumb:

Work your way through all tables being joined from left to right:

FROM table1, table2, table3, table4, ...

For each tableX, make sure that you are relating it back to a previous
table, with an INDEXED key field in your WHERE clause with AND between
them:

WHERE table1.indexA = table2.indexB
  AND table2.indexC = table3.indexD
  AND table3.indexE = table4.indexE

It doesn't matter on table3 if you have it tied to table2 (as above) or
table 1 -- So long as the fields are indexed, and you can trace back from
every tableX to table1 *somehow*

But you wouldn't want just *this*

WHERE table1.indexA = table2.indexB
  AND table3.indexC = table4.indexD

You've got nothing to tie table3 and table4 back to table1, so every
single row in the 3/4 combination is going to be listed with every single
row with the 1/2 combination, in every possible permutation...

Try it with some very small (number of rows) tables just to see what happens!

Your problem is that you are passing in all of $worklogt4 to the date
function, and that *BEGINS* with the first date/time, and that's what PHP
uses.

You need to FIRST break up your single line into separeate lines, based on
the 10-digit time-stamps.

Something like:
$lines = split('[0-9]{10,10}', $worklogt4);

But then I'm not sure you get to keep the date/time -- I never use split
much, myself...

POST variables come from the HTTP interaction.

HTTP is stateless -- Nothing from one POST will get carried over to the
next unless *YOU* do something to make that happen.

You can pass them as HIDDEN INPUT, you can put them in your SESSION, you
can hire/train a squirrel to read them and repeat them, but they ain't
gonna get carried over unles YOU do it.

Neither $co_id nor $Outlet is POSTed.  You assign them in your script, so
of course they have values.

These other variables would work *ONLY* if you manage to transmit $user_id
(used in the queries above) from page to page.

Here you are passing two variables you're going to ignore anyway ($Co_ID
and $Outlet) and *NOT* passing $user_id you need in your queris, and,
well, I don't really know what you are trying to do with the other four
variables, but you've given me a headache. :-)

Sit down with a pencil and figure out exactly what data you need to
transmit from page to page, and what you can just lookup again, and where
the data will come from.

I say again:  POST data will not propogate itself. You MUST
store/propogate it in $_SESSION or as more hidden INPUT or propogate at
least the $user_id so you can look up their info again.

Only problem is that you could have a slight "timing" issue where the
select above gets done, then somebody adds a new image, and then you
display your counts, and then you display the list, and that extra image
is in the list, but not counted.

You *COULD* solve this by wrapping a transaction around the whole mess if
it's really critical, but you probably don't need it.

No, there aren't.

And even the collisions found don't really mean much in the grand scheme
of things, from what I've read.

The worst-case scenario is that in a few years' time, more likely in MANY
years' time, somebody will figure out a way to use hardware not yet
available to crack MD5...  Even that is more likely to be "crack one out
of every 2 billion MD5 values" rather than crack any old MD5 they run
across.

I really wouldn't sweat this in terms of your day-to-day life/programming,
other than to keep your code modular enough to replace "md5" with
something else in the year 2020 or whatever.

>> MD5 collisions were found last year:

Maybe I'm mis-remembering the article and its implications, but I don't
think they can apply that to an arbitrary MD5 hash and reverse it to the
plain-text original...

It's more like a theoretical "hole" that may some day prove to be the
first step in a long long long process of understanding something that
might maybe some day yield a way to de-crypt MD5.

If this is the best answer your database software will let you come up
with, it's time to switch databases :-)

Fortunately, the databases that don't do "LIMIT" have this nifty thing
called "CURSOR" which lets you kind of do the same thing.

At least, all the databases I know of.

Maybe something really stupid and broken like MS Access or something that
doesn't even claim to do SQL like, e, FileMaker???

Even there, I'll bet there's some better answer than pulling all the rows
down just to display a tiny fraction of them.

When $_REQUEST doesn't seem to work with file uploads, it almost always,
in my experience, means I forgot the ENCTYPE="multipart/form-data" on the
FORM tag.

D'oh!

I did that several times, over the years, before it became a habit to type
it for file uploads.

YMMV

Be very careful with timezones. If you have dedicated servers with full

This is nothing to do with domain names, I was simply asking if anyone

I think he wants mirror, sort of...

I will do this if I were you:
Select the server wif the most bandwidth. Call this the master.
The other 2 are slaves.
To sync files:
==
Enable network file system server on the 2 slaves. Export the htdocs 
directories.

Setup the master to mount the exports.
Setup file monitoring tools (maybe fam?) on the master to copy new files to 
the mounted slave directories when alteration of files in htdocs is 
detected.

DO NOT instead mount exports of the master's htdocs on the slaves otherwise 
the slaves will be very slow in serving out files.

Of course, you have to enable security - things like IP 
restriction/encryption on the NFS.

To sync database:
=
Use database slaving tools?
If you are using MySQL, see 
http://mysql.hjc.edu.sg/doc/mysql/en/replication-intro.html. All updates 
from ANY server must be done at the master though.

Or you can just host the SQL server at the master. All queries goes to the 
master.


Hope this helps!
