A little knowledge is a dangerous thing.
Give up now, while you're still sane.
Think about what you're trying to do. You're trying to do something
different on the client every time, but without letting that client know
something is different.
It really really really can't be done. Something needs to be visually
different, therefore something in what the client gets needs to be
different. Do you see why it's not possible now?

ah, but it is possible, if he could change the color of the background and arrow on each page
refresh, then it would be pretty damn hard to cache all the possible combinations of that, plus toss
in a few random degrees of difference with say 3 arrows that point to the right, but one is at 90
deg's while another is at 88 and another yet at 92.
This would make things almost impossible for a computer to see, but the chances of a human screwing
it up would be almost impossible.

hmm, why don't you md5 more then once..
for example, use a condition that will change with every visitor. like
the third num in $_SERVER['REMOTE_ADDR']; or something of the sort.
then make a loop..
say the third num in my ip address is 5
the person that visits after me would get my value, and say you were
right before me and yours was a 7
the md5 check for me would look like
md5(md5(md5(md5(md5(md5(md5($value)))))));
and for the person right after me
md5(md5(md5(md5(md5($value)))));
this way for each visitor, a piece of the puzzle is changed. just an
idea, and have no idea if it would even work for what your doing...

Although I rarely post here (mostly lurking)...
I would think that the mere fact that support for PHP4 ends in 8 months
should be in and of itself a strong argument for the server admins.
In my current position, I code and am responsible for a few different
servers.
It's certainly a strong argument in my eyes.
I'm also kind of surprised that with the amount of time that PHP5 has now
been out that this is still a question for some people. (not directed at you
but maybe the server admins)
Once again, pretty strong argument is, if support for PHP4 is being
dropped..... that must mean that there is much confidence that PHP5 is
mature enough... to be the only supported version in being rolled out in
production environments.
That's my 2 cents worth.

I'm sure Mambo is ready for php5.
The thing is that I have to give pretty good arguments (like some page at
zend or php.net or whatever) to the guys that install the server. I also
know that debian wait until the last moment to put new versions.

The above line does not follow from any kind of logical reasoning. A in
no way implies B as you have ascertained from thin air.

Or... there's some strong arming happening to force the move. PHP4
userbase greatly outnumbers the PHP5 userbase. I think the userbase
speaks louder than the support timeframe.

Rob.

DokuWiki should run just fine under PHP5. It may throw some E_STRICT
errors warning of things that will be deprecated in a later major PHP
release. I doubt DokuWiki needs register_globals, and magic_quotes
shouldn't be a question. Use the strict level warnings as hints to help
you find what needs to be modified in your own code.

Damien Seguy's latest stats showing the adoption rates of PHP5 show what
Rob said.
http://www.nexen.net/chiffres_cles/phpversion/16814-php_stats_evolution_for_march_2007.php
I'm sure many of the polled domains are shared hosts, who have users,
which exponentially complicates the task of migration.

anyone here using the ribs php rsync script?
i keep getting:
rsync: link_stat "/home/site" failed: No such file or directory (2)
does the directory structure need to match on both local/remote servers?
example, i'm trying to back up /home/site to /home/backup
not sure if the remote backup server has to be /home/site as well.. or
if the problem is in the php script as i'm running php5.

You will have to do it using the socket api something like this but
with error checking:
<?php
$sourceip = '192.168.1.1'; // ip you want to bind to
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($sock, $sourceip);
socket_connect($sock, 'example.com', 2043);
// Write
$request = 'GET / HTTP/1.1'."\r\n".'Host: example.com'."\r\n\r\n";
socket_write($sock, $request);
//Read reply
// Close
socket_close($sock);
?>

Another option using streams (php5):
<?php
$opts = array(
'socket'=>array(
'bindto'=>'192.168.1.1:0' //any port will do
)
);
$context = stream_context_create($opts);
$html = file_get_contents('http://example.com:2043', false, $context);

The solution I presented is to access, and act upon, a database as if they
were PHP arrays, meaning that a table is presented as an array of records.
This implies to me that you'll read a series of tables into arrays,
modify the arrays, then update or recreate the database tables from
the arrays. I can't really see how this can work for multiple users
because as soon as a second user reads and starts modifying the data
there will be obvious discontinuities between the two data snapshots,
and updating the tables from one user will erradicate changes made by
others. Is this a single-user application you're working on?
I could index by the order as they are presented by the DB:
$DB['users'][0] is the first user from the query "SELECT * FROM users"
$DB['users'][1] is the second user from the query "SELECT * FROM users"
etc..
But this have many cons. First, without a deterministic order, the array can
change its logic order on the whim of the DB, nobody assures that the order
will be kept after a modification is made to the data, and this can be
confusing and error prone:
$name1 = $DB['users'][3]['name'];
$name2 = $DB['users'][5]['name'];
$DB['users'][3]['name'] = $name2;
$DB['users'][5]['name'] = $name1;
The last sentence may not be writing to the adequate record.
Hmm. I don't see why this wouldn't work -- you're not changing the
keys (3 & 5) required to point to those unique records. I can see a
problem if $name1 and $name2 were themselves the keys, but you're not
doing that in this example.
If that were the problem, though, you could simply mandate a rule
that you can never change the key of an array element that represents
a data record, so that the record sequence remains what it was
originally. However, making your program logic depend on the record
sequence as it was read from the database seems quite iffy anyway
[especially in a multi-user system]; I'd just use the data table's
primary key as the array key and leave it at that. Random access rocks!
From what you write, it almost seems as though you're assuming that
these statements:
$DB['users'][3]['name'] = $name2;
$DB['users'][5]['name'] = $name1;
actually modify the database records they represent. If so, what
system are you using? I just don't see this happening using simple
PHP and MySQL. When you read a data record into a PHP array [with,
for example, mysql_fetch_array()] that array is just a static copy of
the data and doesn't possess any dynamic updating power over the
database. Or are you using an I/O class that you're not showing in
your example code that executes a modifying query each time an "array
element" is changed?
Another possible indexation could be by the value of the PK, but this also
have some problems. First, it can be confusing if the PK is an autonumeric
int, as this might be seen as a numeric indexation.
You can prefix an autonumber field with alphabetic characters to
force it away from numeric indexing:
$sKey = str_pad($aDataRecord['recno'], $iPadLength,
'pk_00000000000000', STR_PAD_LEFT);
$aArray[$sKey] = $aDataRecord;
e.g., recno 12345 becomes array key 'pk_00000000012345'
Using str_pad(...LEFT) ensures that the array keys will be in the
same sequence as the data records even though the autonumber values
will be composed of differing numbers of digits. You just have to
choose a pad length that equals the longest series of digits your
database will generate for an autonumber field.
Second, not all tables
have only one field as PK (I can ask that all tables have at least a PK, but
I can't ask that the PK is made of only one field).
You can construct a single array key from multiple database fields:
$aArray['pk_' . $aDataRecord['fieldA'] . '_' .
$aDataRecord['fieldB']] = $aDataRecord;
unset($DB['users'][$userid]); // delete
Unsetting the array element, rather than retaining it with a deletion
marker, implies that you're intending to recreate the database tables
rather than update them atomically. Is this correct?

Paul

Anyone else has some thoughts on this?
I agree with you, this function seems not working correctly. From what
i see of my testing is that this makes an array, with some iterators
inside it. But all these iterators are the same iterator i started
with. Meaning i get an array of all duplicate iterators. This is not
what it should do i think, but there's no documentation on the
fuction, so i can't compare with the "expected output".
