Re: [PHP] Reseting the auto-increment number in a MySQL database.
holes in sequence of auto increment happen using transaction for insert new record but you don't commit transaction itself it seems that the autoincrement is incremented anyway at least this is my case. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Performance Problem
Hi all, I've been chasing what I think is the same performance issue for about a year and it's driving me batty. First off, the server is a dual core 2.8 P4 with 2G RAM running RHEL5 hosted at The Planet and is under very light load. This problem started last year while the server was RHEL4 and I completely rebuilt it with RHEL5. The PHP-based sites hosted on the server have shown intermittent performance issues when loading. A page might load fine 2 or 3 times, then take 5-10 seconds to complete the next page load. I've gone through everything top-to-bottom to try to eliminate possibilities: First thought was MySQL, so I took that out of the equation and tested pages that didn't use the database and that had no effect. Second though was httpd, so I compared straight HTML with PHP, and found the problem only occurred with the PHP pages. Straight html had no issues, so it's definitely a PHP problem. I've been compiling my own PHP with MySQL binary releases, so to make sure I wasn't causing the problem, I rolled back to RHEL5 httpd, php, and mysql. I even used the RPM's php.ini to try to rule everything out. To try and quantify the issue, I made a PHP page that just had a one-line echo and compared it with a regular html page and ran httperf tests with the following values (run from the server to take network issues out of the equation): httperf --hog --num-conn 100 --ra 10 --timeout 5 The html page always ran with no errors: Connection time [ms]: min 0.2 avg 0.4 max 13.7 median 0.5 stddev 1.4 Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0 On the other hand, the PHP on successive attempts: Connection rate: 6.9 conn/s (145.0 ms/conn, =31 concurrent connections) Connection time [ms]: min 83.3 avg 585.4 max 2215.0 median 406.5 stddev 510.6 Reply status: 1xx=0 2xx=70 3xx=0 4xx=0 5xx=0 Errors: total 30 client-timo 30 socket-timo 0 connrefused 0 connreset 0 Connection rate: 10.0 conn/s (99.7 ms/conn, =6 concurrent connections) Connection time [ms]: min 25.7 avg 232.1 max 1443.4 median 141.5 stddev 244.0 Reply status: 1xx=0 2xx=100 3xx=0 4xx=0 5xx=0 Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0 Connection rate: 6.8 conn/s (148.0 ms/conn, =47 concurrent connections) Connection time [ms]: min 107.4 avg 1066.1 max 1989.7 median 1201.5 stddev 519.5 Reply status: 1xx=0 2xx=22 3xx=0 4xx=0 5xx=0 Errors: total 78 client-timo 78 socket-timo 0 connrefused 0 connreset 0 As you can see, it's all over the place and it shouldn't really be taxing it enough to cause problems on that server. At this point, I don't know what else to do. If anyone can shed any light on this, I'd be forever grateful. I'll try anything and do whatever I can on my end to fix this.

Re: [PHP] Performance Problem
I know my original post was long-winded, but I did mention that my php
tests were run on a single-line PHP script that simply echoed hi so
it couldn't get much simpler than that. But for thoroughness' sake,
I've run the tests against a test file with a php extension with no
PHP code at all, and it suffers the same performance problems/ The
only modules loaded for the tests were gd, mysql, pdo.
For what it's worth, I help manage several RHEL servers at my day job
that run similar hardware and far more bloated PHP builds that have no
performance issues whatsoever. And also, for what it's worth, none of
the other services on the server have problems.

[snip all of the good stuff --- thanks for a well-written question!]
Adriano,
It really depends on what PHP is expected to do prior to serving
the content. Some things to consider:
Are you loading a bunch of modules in your php.ini?
What is the script doing? Is it reading/writing files?
Including files? If so, are they local or remote?
What happens if you take a static HTML page and rename it with
a .php extension and compare load times?
The last of the questions will be of the most help in determining
which of the first two would be more applicable, because when you
rename the extension, PHP will be loaded by Apache. This means:
a.) If the performance is degraded by comparison, it's a
slow-loading PHP engine.
b.) If the benchmarks are comparable, then it's likely
something in your PHP script(s).

Re: [PHP] Performance Problem
OK. I just went through about 10 minutes' worth of cachegrinds, including several httperf tests on that empty php file (which had the usual poor results). According to the cachegrind files, nothing (including the other active web pages) took more than 15ms and the empty php file never exceeded 1ms. Clearly it's not having problems once it gets to processing the files. The issue seems to lie elsewhere with PHP.

Re: [PHP] Declaring arrays? Good practice?
imho
I agree always declare all kinds of variables before using
in the specific situation you have to consider that you are using two
different variables
rthe $foo inside the function and the $foo outside the function I think
its' correct to declar both, imho you should use different names
if you want to check all variables are properly declared you can turn on
error reporting for all during development and wwitch it off again in
production
2005/12/14, Michael Hulse [EMAIL PROTECTED]:
Sorry if this question sounds noobish:
$foo = array(); // Declare first, good practice.
$foo = array('one', 'two', 'three');
Using above as example, is it good to always declare the array first?
I usually/always declare my arrays first, but sometimes I get a bit
confused... for example:
function give_foo() {
$the_foo = array(); // Declare first, good practice.
$the_foo = array('one', 'two', 'three');
// Do some stuff here...
return $the_foo;
}
$foo = give_foo(); // Declare $foo also?
So, should I declare $foo as array and then give it the value of the
function? Example:
$foo = array(); // Declare first, good practice.
$foo = give_foo();
That seems kinda redundant. Thoughts?
Sorry if this is a stupid question... I am self-taught, and I am trying
to shake all my bad coding habits.

Re: [PHP] question

When you say server, does it mean my CPU? By CPU I assume you mean your computer and not the Central Processing Unit. being a CPU is the small chip inside your computer attached into the motherboard which every instruction gets sent to for processing. And yes a server is a computer. Technically what makes a server a server is the fact that it serves something. Take any computer out there say a 133MHz install a web server on it (apache) and boom you now have a server that serves webpages. 2. Do i have to buy a seperate server besides my computer CPU? No but generally it's recommended if your wanting good server performance and a unshakable uptime. By using the computer for every day you work you expose the server/computer to performance hits and possible program crashes that may also affect the underlaying OS. 3. Can i use the software to multiple web-domain that i will create and launch online? I assume you mean you want to be able to host websites from multiple domains and the answer is yes. Apache has that functionality and is well documented all over the place. 4. How will i be able store those data coming from the threads? You store them using those threads however you feel like it? I guess I don't really understand this question. 5. Can you provide a remote server to serve as a database? Php has support to connect to remote database servers yes. you may also run the database server locally to the server. I personally recommend PostgreSQL. Others I'm sure will recommend MySQL.

Re: [PHP] BOOKING SYSTEM
well I did it in the past, at the end after a lot of tests and simulation i decided for warehouse table id_hotel, date, num_total_rooms, num_booked_rooms this is day by day handling it is really flexible you can satisfy each kind of request with very simple queries you also gain more flexibility in period definition you canalso easily handling dsingle day workout and so on 2005/9/20, php @ net mines [EMAIL PROTECTED]: Hi all I have a hotel booking system where for sppecific periods we have specific availability e.g. hotel_id, hotel_name, hotel_fromperiod, hotel_toperiod, hotel_availablesinglerooms 1, Hilton, 20/06/05, 20/08/05, 20 We have a second table for recording the bookings e.g.hotel1_id, hotel1_name, hotel1_fromperiod, hotel1_toperiod, hotel1_availablesinglerooms 1, Hilton, 01/07/05, 20/07/05, 1 2, Hilton, 20/06/05, 25/07/05, 1 3, Hilton, 25/06/05, 27/06/05, 19 4, Hilton, 05/07/05, 05/08/05, 2 Let's say that someone wants to book from the 25/06/05 - 29/06/05 what kind of function-SQL do I have to run to check whether there is availability? (in this example there should be availability between 27 and 29 but not between 25 and 27). Is this way of structuring the easiest and more efficient?

var f must be set
f=1 if0n=4
f=2 if 5n=7
f=3 if 8n=12
f=4 if n12
due to my fatigue I coded four if-if else statement,
in other languages it is possible use conditional epression in switch case
like
switch $n
case (0n=4):
but no in php
any suggestion for more professional coding then 4 if/else statement
For such a small set I'd say that's as good as it gets. However if there
were 100 intervals you could try the following:
function f( $n )
{
$map = array
(
// min, max,f
array( 0, 4,1 ),
array( 5, 7,2 ),
array( 8,12,3 ),
array( 17, null,4 ),
);
foreach( $map as $criteria )
{
if( $criteria[0] === null || $n $criteria[0]
$criteria[1] === null || $n = $criteria[1] )
{
return $criteria[2];
}
}
return null;
}
I think your code is flawed by the way, the lower endpoints are only
compared for greater than value and not equal to value meaning $n with
value 4 would not match any f value.
Cheers,
Rob.

Re: [PHP] Re: Can it be Done?
I understand and thank you Sascha.
Curiosity: why do you use the 'base64_encode' function to send querystring
arguments? I'd rather used urlencode...
Sascha Cunz [EMAIL PROTECTED] ha scritto nel messaggio
[EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
To produce such a JavaScript:
define('_DOMBASE', 'http://yourdomain.com');
echo 'SCRIPT language=JavaScript type=text/javascript'.\n
.'if (document.location == top.location)'.\n
.' top.location='._DOMBASE.'/index.php?goto='
.base64_encode($_SERVER[REQUEST_URI]).';'.\n
.'/SCRIPT';
where the index.php works like:
? if (!isset($_GET['goto']))
$goto = home.php; else
$goto = base64_decode($_GET['goto']);
?
FRAMESET
someframes
FRAME src=http://yourdomain.com/? echo $goto; ?
/FRAMESET
As Stephen reported me recently, this also works with iframes.
