No, it means that when you want to throw a meaningful exception, you
need to type in a message. I mentioned custom exceptions, because that
is what I do, as I multilingualise my messages and do other things with
the exception, like display an XHTML page to the users.

If you mean "Do I have to write custom exception classes?", the no. You
could just use the PHP Exception class.
Eg.
class DBException extends Exception {}
try {
$connection = mysql_connect(...);
if (!$connection) {
throw new DBException('Failed to connect to database');
}
// Database exception handling code
} catch (DBException $e) {
// ...
// Generic Exception handling code (The Exception c
} catch Exception $e {
// ...
}
That's from memory, so there may be a few errors.

Seems there was. Try this:
class DBException extends Exception {}
try {
$connection = mysql_connect(...);
if (!$connection) {
throw new DBException('Failed to connect to database');
}
// Database exception handling code
} catch (DBException $e) {
// ...
// Generic Exception handling code (The Exception class is

} catch (Exception $e) {

}

let's assume php5. all objects are reference like, they behave from a user POV
as objects would in php4 if you passed them by reference explicitly.
that said they're not really references - there is a Sara Golemon article which

php is 'share nothing' architecture ... everything disappears at the end of a
request - nothing remains in memory.
an object stored in $_SESSION will be automatically serialized and saved where ever
the session data is saved (usually to disk).
the only thing to remember is that you must have the class of the object stored in
$_SESSION loaded *before* you restart the session otherwise php will generate an
object of class stdClass.

that's exactly the same method all the ORMs we mentioned earlier
(Doctrine, Propel, Qcodo) work. all these generate classes. ;P
aside from that, metastorage might be as good as any of the others of
course

I don't know about Doctrine and QCodo, but once I looked at Propel and
the way it works was not exactly better than Metastorage generated
classes from my point of view.
What happens is that Propel relies on fat base classes that the
generated persistent object classes need to inherit to do the actual
Object-relational mapping.
Metastorage generates self-contained code. This means the generated
classes are root classes that do only what you need. The generated code
does the necessary database calls directly to store and retrieve objects.
It does not call base classes like Propel generated classes that waste
time composing SQL queries at run-time. Metastorage generated classes
already have the necessary SQL built-in to execute the queries without
further analysis at run-time.
Another aspect is that Metastorage features what is called report
classes. These are classes that perform queries that you define and
generates SQL and PHP at compile time to retrieve data from the
persistent objects for read-only purposes.
For instance, if you want to send a newsletter to a million subscribers
and you just need the e-mail address and names of the subscribers, you
can tell Metastorage to generate a report class that queries the users
objects and retrives just the name and e-mail address. The report
classes return arrays just like plain SELECT queries.
If you use the Propel approach you would need to retrieve 1 million
objects of the users class just to pick the name and e-mail address,
which is totally inefficient in terms of memory and very slow.
There are more differences between Metastorage and Propel (and probably
others approach). I just wanted to make the point that the fact that
approaches use generated code, it does not mean that all provide the
same efficiency.
If you are interested about more differences in the approaches, you may
check the Metastorage documentaion:

this is so that there is a customizable layer that will not be impacted by
subsequent regeneration. qcodo has the same concept and i suspect
doctrine does as well.

Then they must themselves be 'fat'; using inheritance to encapsulate common
functionality is obviously a sound technique.

So does propel.

It has *all* the necessay sql embedded in it? i find this hard to believe.
say
for example i run a query without a limit clause; then i want to run the
same
query with a limit clause; it is simply impractical to pre-write 2 queries,
one
with a limit clause and one without it into the code at compile time.
moreover
i sincerely doubt this is the approach theyve taken because if you just sit
and
think about it for a second, with even a small number of tables the
permutations
on the set of all possible queries would be staggering. such classes that
would
encapsulate said number of permutations would be way beyond 'fat',
i would imagine. so im guessing metastorage does some sort of query
composition at runtime.

so you save some time building queries at runtime for special cases;
thats kind of nice; but i dont think it takes much time to actually build
a query anyway.

thats great, arrays are a little more lean than objects; but obviously they
are not wrapped with any additional functionality; such as the ability to
fetch
the value of a record in a related table or alter the current value.

well lets just remember that even though arrays are just data and therefore
less expensive in terms of memory and quicker to iterate; there would still
be 1 million arrays of data.

i would like to see some benchmarks of propel vs. metastorage. i would do
them myself except that i simply dont have time to do a proper experiment in
the near future. i will certainly consider an analysis of metastorage for a
rainy
day though.

I too believe in Open Source, but there are times when the only way to

Interesting option. Does require more effort, but if you rewrite the
whole thing in C, you might gain some performance too. Of course, once
you've done that, you might even leave PHP out of it, and just run it
as a binary.

Simplest way would be to define your data in an array instead:
e.g. $data = array(1 => array('id' => x, 'entry' => y, 'name' => z), ...).
Then you can do:
mysql_query ("INSERT INTO testimonials (id,quote,name) VALUES
('".$data[$i]['id']."','".$data[$i]['entry']."','".$data[$i]['name']."');");
(normal rules about escaping data should apply to the above - e.g. pass
unsafe values through mysql_real_escape_string rather than put the
quotes in yourself)
Of course if you are inserting a lot of data with mysql, it's *much*
faster to use the extended instert syntax:
INSERT INTO table (col1, col2) VALUES (val1a, val1b),(val2a, val2b),(...);

You are looking for variable variables
http://us3.php.net/manual/en/language.variables.variable.php
example of what is going on.
<?php
# Variable Variables Test
$id_0 = 'zero';
$id_1 = 'one';
$id_2 = 'two';
$id_3 = 'three';
for ( $i=0; $i<4; $i++ ) {
echo ${'id_'.$i};
}
?>
So, for what you are wanting to do. I would do something like this.
<?php
#
# Your other code here
#
for ( $i=1; $i<=16; $i++ ) {
$SQL = "INSERT INTO testimonials (id,quote,name)
VALUES (
'".${'id_'.$i}."',
'".${'entry_'.$i}."',
'".${'name_'.$i}."'
)
";
echo $SQL;
# mysql_query ( $SQL );
}
?>

the output of phpinfo() also tells you where pp is loading in php.ini from (or
trying to load it in).
my guess is the php.ini your editing is not located where php is looking for it.

To solve this problem, I will advice you to probably remove all the former installation. Because PHP do have problem relating to IIS several times.
so it better you install complete pack of PHP Application.
You can use a PHP Application call WAMP SERVER. It's good PHP Application for deploying.
WAMP means WINDOWS(os) - APACHE(webserver) - MYSQL(db) - PHP(platform).
With this, I think you should be okie because there won't be any need to start a new configuration in PHP.INI file.
You can get WAMP Server from: http://www.wampserver.com/en/download.php

From your explanation of the steps you took, it sounds to me like
you forgot to restart your HTTP server (in this case, IIS). Restart
that and all should work as planned.
Changes to configuration files (such as php.ini) are "read in" to
the servers (daemons) when they are executed, and can't be changed
dynamically. The same goes for MySQL, Apache, SSH, et cetera.

Hi
Thank you for reading my post
I am trying to run a php based application using php5 and apache.
but I receive an error like:
*Fatal error*: Call to undefined function imagefontwidth() in */var/www/v603/includes/functions.php* on line *28*
when line 28 and its surrounding lines are:
## create an image not a text for the pin
$font = 6;
$width = imagefontwidth($font) * strlen($generated_pin);
$height = ImageFontHeight($font);
$im = imagecreate ($width,$height);
$background_color = imagecolorallocate ($im, 219, 239, 249); //cell background
$text_color = imagecolorallocate ($im, 0, 0,0);//text color
imagestring ($im, $font, 0, 0, $generated_pin, $text_color);
touch($image_url . 'uplimg/site_pin_' . $full_pin . '.jpg');
imagejpeg($im, $image_url . 'uplimg/site_pin_' . $full_pin . '.jpg');
$image_output = '<img src="' . $image_url . 'uplimg/site_pin_' . $full_pin . '.jpg">';
imagedestroy($im);
return $image_output;
Can you tell me what is wrong with this code and how I can resolve the
problem.
Thanks

that would tend to indicate that it's unavailable yes.
you don't have the [php] GD extension loaded (and probably not even installed)
php.net/gd
mostly likely you'll have to ask your sys admin to install/activate this
extension ... and if you have cheaphosting then likely the answer will be
"no we don't do that" - in which case find other hosting?

I can attest to what Daniel is saying about PilotPig. I've had a site
hosted there for about 5 months now and have been really happy with
everything: costs are reasonable, lots of modules available, respectful and
timely reponses to questions and/or concerns. Just a great overall
experience.

there is a good reason for this being internal - and if you search the
internals mailing list archive you'll find plenty of discussion about it.
whether it's bad depends on whether you look at it from a phper's POV or a
sysadmin/package maintainers POV - there is no way to make everyone happy in this
situation AFAICT.

All other points being valid, Jochem, I disagree with this. I've
never forced a setting on any of my PHP installations, and so far
(knock on wood) I've never had a problem. I think PHP does a fine job
of reading the server time and zone.

But I think Martin said, and my experience has taught me, that PHP 5 uses an
internal database of timezone info and does not reference OS time (I'm
assuming that's what you meant, Daniel, by "I think PHP does a fine job of
reading the server time and zone."). On one of the Linux web servers that I
maintain, I had the need to turn off daylight savings time, which was a
interesting task in itself. But I could never get PHP5 to honor the OS time
as it always changed when in DST. So I had add code to applications that ran
from that web server to test for DST and account for it in certain
displays. This was very different behavior form PHP4 where the same
applications ran just fine.

I might have put my foot in my mouth, but probably not. I've used it
a few years ago and it was just a horrible mess of code. All the
end-user interfaces were pretty nasty too. At the end of the day
though it is your choice what software you use, but from my experience
it is a poor quality piece of software.

I haven't looked at the code of it yet... Just downloaded it,
installed it, and started playing from an end user stand point :)
figure if I can't tell the user how to use it, it doesn't matter what
kind of a rats nest the code is :)

While I agree that if the end user doesn't get it, then you don't get
paid... but quality matters if you have to extend/maintain/secure it.
Well, I guess not. Look at how wildly popular MySpace is.

im guessing most people who use oscommerce or zencart dont ever
look at the code, let alone extend it. a couple years back i setup a
zencart install for someone and i remember looking on the forums at
that time.. someone was trying to mod it a little and one of the core
devs said something like 'what are you doing, mucking around in the
code..'; i was somewhat shocked at that.
did you see the thread that started last night about a zencart module
and php arrays?? if thats indicative of the typical user (which i suspect
it is) i think these guys are safe to assume not many people are going
to extend their code. but thats no excuse for poor code (here i assume
the code is bad, but from a cursory glance it looks like zencart has
improved since i last used it [though ive not looked at the code much]).
if i were going to use it id almost certainly end up maintaining some sort
of forked version or perhaps just grabbing some functionality from it, like
maybe integration w/ a payment gateway or something. hopefully that
cant be too bad, and small enough to easily tweak in the event it needed
a face-lift.

I agree. I think the problem was too many people throwing in
code, and not enough control and checking. In my opinion, osCommerce
can be equated to a cheetah: very nice, fast, and sleek when you see
it running, but tear it open and the guts are nasty.

If you look at plugin architectures of projects such as drupal,
phorum, or serendipity you can see there are better ways of doing
things rather than messing up the source code. I recently found
Magento, and the code looked really promising, but it is just too
slow. Having to diff your project and upgrade changes is a horrible
thing each time a security patch comes out.
A big part of what I do is work on e-commerce solutitons for local
stores and such. Each one has wildly different needs that just cannot
be packaged up easily. So in the end I've implemented my own solution
because I felt that to be able to address clients needs properly I
needed a system where swapping out the hard parts were easier. Now
when somebody comes to us with their fancy new payment gateway I can
read the docs and integrate it fairly easy without breaking anything
because I know how the other parts work and can implement accordingly.

Does DISTINCT really compare all columns? I would think it would only
compare the columns explicitly included in the SELECT clause.

I have seen discussions where in GROUP BY can be faster than DISTINCT
depending on whether the query uses things like correlated subqueries,
but this is not applicable in the current case. At any rate, I don't
want to stray the conversation any further away than I already have.

attached mail follows:
You are correct, but that is what I meant by all columns (all those in the
query, and therefore subject to the distinct).
At this point different database engines work differently, without an order
by, some will use the primary sequence, some will scan table space (in other
words, without an order by [or group by], some engines will give you a
performance hit). It's always good practice to write your queries to help
your DB engine find an index.

Greetings,
Could someone please point me in the right direction? I am trying to have
PHP find out if a directory has files in it and then if it does, display and
include, if it does not, then not display the include.
I have looked at the Manual and did not really know where to look.
Thanks,

oooh, goodie! You get to play with my new favourite toys - SPL!
Try this:
public function lsDir($dir, $type='files')
{
$iterator = new RecursiveDirectoryIterator($dir);
foreach (new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file)
{
if ($file->isDir()) {
$dirs[] = $file->getPathname();
} else {
$files[] = $file->getPathname();
}
}
if($type = 'files')
{
return $files;
}
else {
return $dirs;
}
}
(untested - written from mind dump - so please test 1st)
Then, AFAIK SPL also has an __autoload that you can use.

Turn left at the next light...

Display what? The directory name, or the list of files?
> and include,
What do you mean by include? the include command from PHP?
if it does not, then not display the include.
Again, what do you mean exactly?
> I have looked at the Manual and did not really know where to look.
Which part of the manual did you look at?
Here are a few parts of the manual that I would start with.
This will get you a complete list of files, directories, etc... in a given directory
http://us2.php.net/manual/en/function.glob.php
This class allows you retrieve and iterate through a directory listing.
http://us2.php.net/manual/en/class.dir.php
Between the above two options, I recommend glob()
Now loop through the results with foreach or while .
http://us3.php.net/manual/en/control-structures.foreach.php
http://us3.php.net/manual/en/control-structures.while.php
run the following two commands on each value of the given array to determine
whether the given entry is a file, directory, or something else
This will allow you to determine if something is a file
http://us2.php.net/manual/en/function.is-file.php
This will allow you to determine if something is a directory
http://us2.php.net/manual/en/function.is-dir.php
if you found a directory, use this to change to that directory and start the
process all over again.
This will allow you to change your current working directory to a new directory
http://us2.php.net/manual/en/function.chdir.php
Hope these help

Twelfth Night, Act II, Scene V

attached mail follows:
Hi there,
Is it possible to make the declare(ticks=1) statement apply to *all*
functions executed in a php script, regardless of scope?
I wish to write a profiler script to basically dump all the function call
times through the execution of a script. So far, I can only get it to work
for functions called via global scope.
My code calls only one function from the global scope, and then a whole lot
of functions in classes are invoked. The tick function is only invoked once
from calling this one global function.
Here is my code:
<?php
declare(ticks = 1);
/**
* Profiler
*
* version SVN: $Id$
* author Scott McNaught
*/
class Profiler
{
protected $m_arrProfileData = array();
protected $m_strCurrentFunction = null;
protected $m_iLastTime = null;
/**
* Begins profiling
*/
public function start()
{
$this->m_iLastTime = time();
}
/**
* Finishes profiling and dumps the results
*/
public function end()
{
var_dump($this->m_arrProfileData);
$this->m_arrProfileData = array();
$this->m_strCurrentFunction = null;
}
public function tick()
{
$arrBacktrace = debug_backtrace();
if (!isset($arrBacktrace[1]))
{
return;
}
$strFunction = $arrBacktrace[1]['function'];
if (isset($arrBacktrace[1]['class']))
{
$strFunction = $arrBacktrace[1]['class'] . '::' .
$strFunction;
}
$iTime = microtime(true);
if (!isset($this->m_arrProfileData[$strFunction]))
{
$this->m_arrProfileData[$strFunction] = $iTime;
}
$this->m_arrProfileData[$strFunction] += $iTime -
$this->m_iLastTime;
$this->m_iLastTime = $iTime;
$this->m_strCurrentFunction = $strFunction;
}
}
$pProfiler = new Profiler();
register_tick_function($pProfiler, 'tick'), true);
?>
Then from index.php.
<?php
if(isset($_GET['profile']))
{
include('profiler.inc.php');
}
function execute()
{
$pClass = new SomeClass();
$pClass->someFunction();
}
execute(); // TICK IS CALLED FROM EXECUTING THIS
?>
So a tick is made from calling execute() from global scope, and that is it.
I want it to tick when someFunction() is called.
I would really appreciate any help that anyone can give me with this as I
have struggled with it for a while, and there is not much documentation
about this anywhere.
This could potentially benefit a lot of people if engineered right. I am
trying to make a profiler include file which will be able to be used with
one line of file.
This will allow people to:
. Get quick profiler results on demand by adding something to the
query string - eg - ?profile=1
. Get profile results for novices without having to mess around
installing php binaries such as APD / zend debugger etc
. Profile on demand on production servers without having to install
a resource intensive debugging module
Any help greatly appreciated.
Thanks,
Scott McNaught
