hi there, this is typical app for db repliction mechanism. it depnds of the size off your project. have a look here: http://dev.mysql.com/doc/refman/5.1/en/replication-howto.html if this is oversized for u do a dump of each table without the auto_increment fields. if u read in these tables the main database then does use its own record id. to identifie these records use a subsidairy finegerprint field. another way would be not to use a ai field for identifying the record, use a timestamp field to have an unique index on the tables. it is very unlikeley that two records are written at the same time in the various subsidaries. a timestamp field is a breakdown to the milisecond. however there is still a chance of 1 to some billion, that two records have the same key. just some possibilities cheers ralph ralph_def...@yahoo.de Leidago !Noabeb leid...@googlemail.com wrote in message news:5bcf496e0908110004w94d29c2j4b01806822ca0...@mail.gmail.com...

Re: [PHP] APC optimization in CLI
Daevid Vincent wrote: From: Robert Cummings [mailto:rob...@interjinn.com] However, accelerators don't make scripts faster per se. They merely cut out the script reading and parsing time. Which is a HUGE portion of time since PHP is a two-pass step. One that reads and compiles to opcodes (with syntax checking) and another which actually executes it. No, it's a small portion for most CLI scripts. So, while you may experience 10% gain within the first second of your script running, the use of an accelerator should have no bearing down the road except for the initial dynamic load of other scripts at runtime. This is sort of misleading. No. It is not. You will experience faster page loads if it's a web php file, and if APC does allow you to run cached scripts via CLI, then these scripts will start execution immediately too. I've already mentioned it's efficacy in a web environment. I am explaining the cases where you won't get much value... namely CLI scripts. Long running scripts will see almost no benefit from an accelerator. PHP scripts are (like it or not) NOT designed to be daemons and run for long Maybe you mean PHP was not meant to be used for daemons because I SURE AS HELL designed some of my scripts to be daemons and run for a long time... some run for months uninterrupted (usually need to reboot for OS updates once in a while). As for the former comment... that's a matter of opinion. periods of time. The GC is no optimized for such things. It's quite inneficient from what I've read. The whole purpose of a PHP _page_ is to get in and get out. Hit it and quit it. Therefore memory efficiency is not as important as speed and ease of use. The GC works fine if you avoid circular references. This is the general reason why CLI acceleration isn't very useful. That said though, one could certainly glean an advantage if they had a cron job or other daemon that was loading a script often. As is probably often the case, moreso than a long running script. I would argue otherwise when the CLI is being used. I think a code optimizer is what would be desired if you're trying to make a faster script. However in this day and age, I suspect that the 2nd phase of the compiler already does all the optimizing it can before creating the byte code. You would be wrong... very few accelerators have bundled optimizers. Some may do a small amount of optimization, but not a lot.

However, my solution (after reading others) is for an alternating row
color (a boolean operation).
The problem was NOT making every third row a different color or
making every row a different color. Those problems would require
different solutions.
There is nothing wrong with embedding php within html, which is
really a misnomer because it's the php interpreter that's sending the
resultant html to the browser. It is not sending php snip-its for the
browser to handle. So, embedding code such as:
tr class=row?php echo($i++ 1);?
Is a valid statement that works. It would be nice if you initialize
the $i value, but it will work either way.
My solution, provided via the above link, is a valid solution.

?
TIA! -G
If I was going to do that then I would use jQuery:
script type=text/javascript
$(document).ready(function(){
$(table tr:even).addClass(even);;
$(table tr:odd).addClass(odd);;
});
/script
And yes I know that this is a PHP mailing list lol

Re: [PHP] Synchronizing autonumber fields
At 9:04 AM +0200 8/11/09, Leidago !Noabeb wrote: Hi I have the following tables setup in MYSQL: Region 1 Region 2 HQ Tbl1 with autonumbered (PK) Tbl1 with autonumbered (PK) Tbl1 autonumbered-PK To explain the above. Basically there are two regions that collect information and then at the end of each month they have to send the information to HQ. This is fine, but the problem comes when the information (the data in the tables) is submitted to HQ. All three tables have the same names and the same structure. We want to synchronize the information sent by the regions into one table at HQ. How can we do this without having the duplicate number problem? Leidago : Basically you have data from Region 1 and Region 2 and you want to send that information to HQ. There are several ways to do this, but why not simply have a field in your table that defines which region. Clearly, HQ doesn't want to lose track of where the data came from, right? As such, I don't see any problem with HQ receiving data from either region regardless of the possibility of the data having the same number problem, whatever that may be. The number problem is reminiscent of one of those We have to consider the index of the records for some purpose when that's usually for the internal workings of the database. If you want to access this data like a relational database, then you can use the index. But remember that the indexes do not have to be sequential without gaps. In the real world records are both created and deleted. In any event, Region 1 data might have: Index - Name - Address 1. Sam 123 Main 2. Joe 456 Elm 3. Ed 789 Oak So Region 2 data might have: Index - Name - Address 1. Harry 456 Oak 2. Sally 789 Pine 3. Wally 123 Maple Thus, HQ data would be: Index - Region - Region Index - Name - Address 1. 1 1 Sam 123 Main 2. 1 2 Joe 456 Elm 3. 1 3 Ed 789 Oak 4 2 1 Harry 456 Oak 5. 2 2 Sally 789 Pine 6. 2 3 Wally 123 Maple Just add the data sent from Regions 1 and 2 to the HQ database. Also, note that the indexes do not have to match, or be sequential without gaps -- they could have been: Region 1: Index - Name - Address 456. Sam 123 Main 458. Joe 456 Elm 560. Ed 789 Oak Region 2: Index - Name - Address 1010. Harry 456 Oak 1014. Sally 789 Pine 1021. Wally 123 Maple Thus, HQ could be: Index - Region - Region Index - Name - Address 4567. 1 456 Sam 123 Main 4568. 1 458 Joe 456 Elm 4569. 1 560 Ed 789 Oak 4570 2 1010 Harry 456 Oak 4571. 2 1014 Sally 789 Pine 4572. 2 1021 Wally 123 Maple This is the way I would solve this problem. In fact, depending upon what you want to do with the data, I might dispense with recording the Name, Address, and other such data in HQ and just record the indexes from Region 1 and 2. After all, that's redundant data unless you're going to drop the data collected in Region 1 and 2 after the exchange. If so, then there's no need to record their indexes.

[PHP] Class Problems
Hey all,
Is there any reason why this shouldn't work correctly on a server
running PHP 4.4.7:
?php
class testClass
{
private $foo = 'bar';
}
print 'wtf';
?
I would at the very least expect to see the 'wtf' printed out. I've got
a whole class I've written that works fine in PHP 5, but on PHP 4
server, it does nothing with even this simple example.
Any ideas?

The private keyword was added in PHP 5. PHP 4 doesn't have visibility
identifiers. In PHP 4 you have to use var, which is then always public.
Or you could just use PHP 5 instead of a dead language. :-)

[PHP] Re: Upgrading to PHP5.2.x
'Twas brillig, and Alberto García Gómez at 11/08/09 16:05 did gyre and gimble: Dear Fellows: I want ot upgrade my PHP from 5.1.x to 5.2.x. I want to do using rpm, but any time that I going to upgrade the rpm request me more dependencies. How can I configure my rpm (or other command) to automaticly satisfy my dependencies. This sounds very much like you are mixing and matching different sources of RPMs. Linux distributions are not like Windows machines where you can just install any given application, they are an integrated set of interdependant packages. It is not at all recommended (read: a very bad idea) to install e.g. RPMs build for one OS version (e.g. RHEL 5.x) on an older version (e.g. RHEL 4.x). Doing so can cause numerous problems due to compiler changes/optimisations and small ABI breakages that are incompatible with the dynamic libraries used etc. Even if you do pull in all the dependancies when installing a RHEL5 version of PHP on RHEL4 (just an example), it will not necessarily work for the above reasons. Similarly, if you do run into problems you will not get any support (paid or otherwise) for such a setup. So please don't undertake this upgrade without fully appreciating what is going on. If you really want to install the RHEL5 version on RHEL4 (again just a random example of a distro), you should download the source rpms and rebuild them on RHEL4. You may have to rebuild quite a few dependant packages to get a fully working system.

PHP4 does not support classes that much.
Especially private/public keywords.

Ah, I was looking up in the documentation, but seem to have missed that.
Just changed the code, and it's working again! The public/private thing
will only really be an issue if someone other than me is using this

You can use a single quote string (instead of escape the \n)
The result is the same, but is more legible.
$sql = preg_replace('|\n#[^\n]*\n|', '', $sql);
Personally I try to not use double quoted.
PHP parses single quoted very much faster.
# for this
echo Hi, $name, wellcome $home;
# I use
echo 'Hi, ', $name, ', wellcome ', $home;
# or
printf( 'Hi, %s, wellcome %s', $name, $home );
And of course, this is a matter of taste!

Also, for further clarification, the junk output I'm getting has the letters PNG in the first few characters, so I'm pretty sure this is a PNG image yes!

Re: [PHP] Image Headers break when image is out of bounds
@Adam The headers_sent() wasa test to ensure that no other data was creeping into the headers before I wanted it to. Keeping it in does no harm, as it is basically saying, if there are no headers that have been sent, send the correct ones for the image. But if there are headers that have been sent, it sounds like they would not have been the correct ones. Which I think would cause exactly the problem you're describing. Ben

It was a red herring that the image was displaying correctly when the drawing commands were all inside of the image area.

This sounds interesting. Could you expound on this a little
more and
perhaps list a couple of the templates you mention?
Thanks,
Frank
There are a number of options for templating in PHP such as smarty, Dwoo
and PHP itself, though the syntax can be rather messy. Personally I just
use a simple find and replace macro system to expand custom short-hand
code into the more verbose PHP, then run it through exec and capture the
result to a variable with output buffering, the class folows:
?php
class view
{
var $str;
/*++
* Load in template file and expand macros into PHP
++*/
function __CONSTRUCT($tplname)
{
$fh = fopen($tplname, 'r');
$this-str = fread($fh, filesize($tplname));
fclose($fh);
$this-expand_macros();
}
/*++
* Run the template and return a variable
++*/
public function parse_to_variable($array = array())
{
extract($array);
ob_start();
eval($this-str);
$result = ob_get_contents();
ob_end_clean();
return $result;
}
/*++
* Expand macros into PHP
++*/
private function expand_macros()
{
// Expand if macro
$this-str = str_replace(if, ?php if, $this-str);
$this-str = str_replace(eif~, ?php endif;?, $this-str);
// Expand loop macro
$this-str = str_replace(loop, ?php foreach, $this-str);
$this-str = str_replace(eloop~, ?php endforeach;?,
$this-str);
// Expand display macro
$this-str = str_replace(dsp, ?php echo, $this-str);
// Expand end tag macro
$this-str = str_replace(~, ?, $this-str);
// Add PHP close tag to exit PHP mode
$this-str = ? . $this-str;
}
}
This loads template files like the folowing:
form enctype=multipart/form-data action=dsp $upload_url ~
method=post
pinput type=hidden name=MAX_FILE_SIZE value=900 //p
pUpload new file, max size dsp $max ~:/p
p
input name=uploaded_file type=file /
input type=submit value=Send File /
/p
/form
table
tr
th width=180pxFilename/th
th width=60pxLink/th
th width=90pxSize (KB)/th
th width=50pxDelete/th
tr
loop ($files as $file): ~
tr
tddsp $file['Name'] ~/td
tda href=dsp $file['Path'] ~Link/a/td
tddsp $file['Size'] / 1000 ~/td
tda href=dsp $file['d_url'] ~X/a/td
tr
eloop~
/table
---
And it can be used like this
$dialogue = new view(template/file_display.tpl);
$dialogue = $dialogue - parse_to_variable(array(
'upload_url' = $upload_url,
'max' = $max_size,
'files' = $files));
the $dialogue var now contains the compiled template, ready for displaying
or integrating into another template.

This is probably flame-war tinder, so I'll try to tread more delicately in the future. Next you know we'll be on the ternary operator and which is better, Mac or Windows. ;-) Ben
Re: [PHP] how to say inverse your value (to a boolean)?
What a lot of good ideas spawned from the OP!
I am learning many things,.. while also actually working (paying
bills), so I regularly have to just go with what I know well.
Anyway, I already have the forearch { loop (for other reasons it is
necessary), and I only needed one color to alternate with the default
white.. so I used this:
forearch { ...
$tableRowBGcolorBoolCounter = !$tableRowBGcolorBoolCounter; //-boolean
on and off
(which then sticks in one CSS class or another for that tr.

Re: [PHP] Embedding foreach loops
Allen, you off and running again? Sure am, thanks, on to the next set of issues. Seems like programming is always moving on from one error to the next :) Currently, I am having trouble with echo and php line-returns. It works on one part of the code, but not on another (instead, prints it to html). For example: [code] $show[show_01][price] * $show_01_qty = $Total_show_01; echo \ntr\n\t; echo tda.$show[show_01][price]./td/n/ttd*/td/n/ttdb. $show_01_qty./td/n/ttd=/td\n\ttdc.$Total_show_01./td; echo \n/tr; [/code] outputs this html [code] tr tda/td/n/ttd*/td/n/ttdb/td/n/ttd=/td tdc/td /tr [/code] Additionally, it won't display the variables, as you can see, even though they will echo out further above in the document. Odd... well you escape a newline char with this slash: \ and not this one: / notice you were not consistent with your use of them. as for the array not being parsed inside your echo statement - I don't see the issue by looking now. Are you saying the EXACT same code does output the expected value for those array elements higher up the script? Show us the code where it is working and again where it is not.. side by side (pasted just after each other in a new post to the list). I assume you are past this next point, but always remember var_dump($myArray); is your friend. Put it just before where you try to echo out some part of the array.. check to be sure the value is there is that element of the multi-dimensional array the way you think it is. -John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Are you sure you're not confused with short_open_tags ie. ? ? -- which I
am fully against (as am I against % % too), although sadly they are lumped
into the same directive, when IMHO they should be separate.

2. Not using echo or print.
?= ? is a fantastic shortcut to the antiquated ?php echo ; ? B.S.
The vast majority of your page is output in little fragments like this, so
why not keep it clean and easy to read. Why would you purposely choose to be
more verbose than you need to be for something as basic as print.
You actually recommend breaking in/out of php?
Hell yeah I do. THAT is one of the MAIN reasons to use PHP. Otherwise, why
not just render your whole page with a bunch of $html .= 'trtd...';
tags and print $html at the end. Welcome to the year 2000 my friend.
You're probably the same kind of person that does this crap:
if ($foo == true)
{
echo A;
}
else
{
echo B;
}
(complete with extra braces and checking for 'true' explicitly, but not
using === in such cases)
Rather than a much cleaner, easier to read/write and more concise:
?= ($foo) ? 'A' : 'B' ?
3. Using uninitialized variables (I run with the E_ALL crowd)
I'm so happy for you. Do you have a membership card and everything? That's
your own masochistic fault then. I run with the
save-myself-the-headache-and-write-clean-efficient-code crowd.
4. Using the tr class='' and not the td class=''... Hmmm
Maybe you're new to how HTML works, but if you want to highlight a ROW (as
the OP did), then you put the background color on the highest parent that it
applies to. Hey imagine that, there is a TR tag which stands for TABLE ROW
tag. Seems obvious to me. This reduces your page size in kilobytes, makes a
much cleaner HTML rendering to read in source, and is the PROPER way to do
it.
}
No need to initialize $dr as by default PHP will make it a
boolean false,
then each itteration, it will toggle true/false and
substitute the CSS class

?php
$arr = range(1, 10);
$i = 0;
foreach ( $arr AS $row ) {
$row_color = ( ( $i++ % 2 ) ? 'green' : 'red');
echo $row_color;
}
?
another (neat|strange)+ way I use the above is like so
style
.rowColor0 { background: #FF; }
.rowColor1,
.rowColor3 { background: #EE; }
.rowColor2 { background: #DD; }
/style
?php
$arr = range(1, 10);
$i = 0;
foreach ( $arr AS $row ) {
echo 'trtd class=rowColor'.( $i++ % 4
).'''.$row.'/td/tr';
}
?

[PHP] is there any way to get realpath cache hit ratio of php?
hi, Is there any way to get realpath cache hit ratio of php? realpath_cache_size integer Determines the size of the realpath cache to be used by PHP. This value should be increased on systems where PHP opens many files, to reflect the quantity of the file operations performed. realpath_cache_ttl integer Duration of time (in seconds) for which to cache realpath information for a given file or directory. For systems with rarely changing files, consider increasing the value. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
