Re: [PHP] How do YOU set default function/method params?

why bother, i use available good library

Ok, bad example. I already use SwiftMailer.  My "problem" though has nothing to do with sending an 
email.  I should have known someone would take it too literally.


Think a little more general.  This is not a specific thing to simply sending an 
email.

Could be database method calls from a class object, HTML CGI function, etc...

As for a different example.  Say you had a function that you had to pass (multiple) arguments to. 
But, with those arguments, you had defaults that you would like to inside the function even if they 
were not sent when you called your function.  But you do not want to be forced into entering ALL the 
arguments of a function call in a certain order.


Try this

function createHTMLBox($title, $content, $params=array() ) {

$defaults = array(
'id' = uniq(),
'class'  = 'box',
'encode' = TRUE,
);

$params += $defaults;

if ( $params['encode'] ) {
$title   = htmlspecialchars($title);
$content = htmlspecialchars($content);
}

# Obviously, I will be using the DomDocument class for this in the real 
world
# But for simplicities sake, I used the following.
$box = <<
  {$title}
  {$content}


BOX;

return $box;

}


Then, I call it like this:

echo createHTMLBox('This is my TITLE',
   'Item 1Item 2',
   array('encode' => FALSE));

echo createHTMLBox('This is my TITLE',
   'Item 1Item 2');

Both of the above will have different output to the screen.

Hope this clears things up.

Spry is Adobe's AJAX framework similar to jQuery.  Are you having problems 
doing remote ajax call for xml data via Spry?

[PHP] Time Problem: always ten past xx

2009-10-06 Thread Matthias Laug


Hey everybody,

I've got a strange problem. Using PHP5.3 on my MacBook.

There is a script, which handles input from user, in this case a date  
and time.


So I get for example "10:30" and "06.10.2009". Standard german time  
format. Now I try to get the correct timestamp:


$time = strtotime("06.10.2009 10:30");
var_dump($time);
var_dump(strftime("%d.%m.%Y %H:%m",$time));

But the result is as

int 1254817800
string '06.10.2009 10:10' (length=16)

The minutes are always "10", no matter what time I get.

Anyone a clue?

Thanks, Mattes

P.S.: default timezone is set to

date_default_timezone_set('Europe/Berlin');

there are filters used for validation as well in php, maybe those filters,

Hi Mert,

But we're not talking about date() here, we're talking strftime().

According to the manual %i doesn't do anything in strftime(). Closest match
is %I which is 12-hour format for hours.

[PHP] Spry, XML, PHP and XSLT Hell

2009-10-06 Thread Matthew Croud



Okey Doke,

I'll try and be brief,
Well, my client agreed to a small online store that would hold the  
same stock items where only the quantities would differ, we agreed  
that, due to infrequent changes, I would make pages for any new items,  
and she would control stock etc using an e-shopping package I bought.


The site also has a page of Returned items, this takes the form of a  
Spry list, which uses an XML  list of clothing and their properties.

 It all worked great.

Yesterday my client said she wanted the ability to add, remove, edit  
new products by herself,  eek!
I thought about implementing another list similar to the returned  
items page, but I learned that XML will turn HTML elements like < and  
> into < and >


Then someone on this wonderful mailing list mentioned that HTML can be  
stored in XML using XSLT.


I suppose my question is, to what extend can XSLT decorate and display  
an XML file, can I add style sheets and rollovers, can I control the  
cacheing so that users wont need to empty their cache to see changed  
results ? Does it all work fine with PHP when I "include" it in a file ?


Sorry if this is a bit weird, but I'm bricking myself with this one,  
and I would just like to hear some voices from people who have been  
there and bought the t shirt,


Cheers folks!

Matt.

To me the key word in your question is "default". Here is a send mail example of 
how I do it. You'll see that I assign default stuff in the function. The all 
caps are constants set in my config file. For extremely high volume 
applications, one could memory cache the defaults.


I also use arrays assigned in my config file and then assign the array in the 
function using "global". When I do this, I immediately reassign the array so the 
function can't change the the assignments made in the config. e.g.,


function foo()
global booArray();

boo2Array= booArray(); Only use boo2Array() in the function.

function pearEmailSend($recipient, $emailSubj, $emailText, $applicEmailAddr)
{
$emailTo = $recipient;
$headers['From'] = $applicEmailAddr;
$headers['To'] = $emailTo;
if(!empty($emailCC)) $headers['Cc'] = $emailCC;
$headers['Return-Path'] = $applicEmailAddr; //or can use SMTP_USER; bounces 
are sent to applic address

$headers['Reply-To'] = $applicEmailAddr;
$headers['X-miniReg'] = APPLIC_NAME;
$headers['Date'] = date('r');
$headers['Subject'] = $emailSubj;
$params['debug'] = EMAIL_DEBUG; //Careful, do not leave on, creates a nasty 
message for admins

$params['host'] = $_SERVER['SERVER_NAME'];
$params['auth'] = true; //binary, set in config; some servers require auth
$params["username"] = $applicEmailAddr; //was SMTP_USER; //If auth true,

[PHP] Active Directory LDAP Help

2009-10-06 Thread Devendra Jadhav

Hi All,

I am new to LDAP.
I want to create user on AD(Active Directory)
I have written script to do same, but I am getting "Operations error"
even I am successfully connected to AD and bounded with correct username,
password.
Also where will I get all attributes with its meanign... which attributes
are compulsory... different types of objects like users, groups,
organizational units and their attributes ...
where will i get all this information?

Help appreciated.

Why don't you use linux solutions like RedHat Directory Server or 
Mandriva Directory Server instead? (LDAP based too)
These solutions are scalable, free & fully documented on the web, not 
like this shitty MS AD (but is there a non-shitty MS product :p)


This is also much more easier to debugg... (linux...)

I just think this is an ambiguous line of code that wasn't thought
through. The presence of the postfix operator makes the result
undefined, no matter what language you are using. It will be an accident
if you get the results you are expecting.

I agree that the operation is illogical, I must disagree about accidents.

In PHP that operation will mean assign to the new $a variable the value 
returned from the other $a variable before the increment.

There is no mystery here, imho.

The behavior of the ++ operator is the invention of Kernighan and Ritchie.
I don't imagine they ever foresaw anyone doing something as silly as

a = a++;

except under the rarest of circumstances.

No matter how silly it can looks like (a = a++) it is still completely valid
code and it SHOULD run without problems.
If we analyse any portion of code (like a simple assigment) out of context
it'll always looks like this, just silly (in this case it's really really
silly).

One point here, that nobody mention, is the side effect.
++$i has a totaly different side effect than $i++

Sometimes you don't need the side effect but in other situations it really
matter.
Does these behaves exactly?
for($i=0; $i<10; ++$i)
for($i=0; $i<10; $i++)

There is no side effect on the incremental section because the result is not
evaluated.

and what about these?
$array[ $index++ ] = $elem;
$array[ ++$index ] = $elem;

You can read more about the side effect at

different benchmarks showed ++$i is usually faster than $i++
In that loop case, yes, what's happen internally is exactly the same, $i will 
be from 0 to 9, in the other case obviously is not the same.

but pre increment and post increment are truly basic stuff ... I don-t see all 
this need to study the case, it's pretty simple, as is that operation, in PHP.

In other languages, could have been the same, rarely in scripting languages 
though, at least those with still primitive scalar values (int, float, string, 
bool)

it's traditional to do so. it reminds me of the bit about subtly
incompatible shells in unix from "Real Programmers Don't Use Pascal":

"Even Unix might not be as bad on Real Programmers as it once was. The
latest release of Unix has the potential of an operating system worthy of
any Real Programmer-- two different and subtly incompatible user interfaces,
an arcane and complicated teletype driver, virtual memory. If you ignore the
fact that it's "structured", even 'C' programming can be appreciated by the
Real Programmer: after all, there's no type checking, variable names are
seven (ten? eight?) characters long, and the added bonus of the Pointer data
type is thrown in-- like having the best parts of Fortran and assembly
language in one place. (Not to mention some of the more creative uses for
#define.)"

we could collect a list:

gnu make vs bsd make
how many subtly different versions of grep are there?

but i'm, sure it's been done already and i guess it's off topic.

XHTML is just XML, so yes you can. I think the XSLT you're looking for
would be something like  which should just mirror
what XML you have in your source document. So if the XML it is matching
and outputting is the HTML, it will show as HTML.

  As XHTML ypu can integrate it in an XML, by the use of XMLNS. But it

  In the XML, you declare two XMLNS. In the XSLT, you declare three XMLNS.

2009-10-06 Thread Andrea Giammarchi

er ... tedd, whatever, usually ++i is faster in almost every language, and even 
C developers could use these kind of micro optimizations.

Speed, even in this SuperCPU era, is still relevant, we would not need 
benchmark to compare programming languages for each purpose.

Of course in a crappy application, the usage of ++i rather than i++ won't make 
any difference, but specially for that kind of for loop where there is 
absolutely no harm or side-effect using ++i rather than i++ ... if ++i could be 
0.0001% nobody have a valid reason to avoid it.

Put in this way: I need to do the same thing, one could be better ... why on 
earth should I use the other way?

I just develop applications, where I can micro-optimize, I do it ... I have 
never had speed problems, but maybe I am just lucky.

Re: [Fwd: [PHP] Sessions in databases]

2009-10-06 Thread Sam Stelfox

If you are distributing your application over multiple servers, using a 
database for session tracking allows a user to continue there session 
regardless of which server their request bounces too. It prevents the 
need for 'sticky' network connections which time out anyways. Databases 
can make scaling applications to enterprise size considerably easier. 
There are other file based solutions that are dirty and require you to 
play with file locking and all that nastyness.


You also don't need access to the php.ini file to implement session in a 
database, check out http://php.net/session_set_save_handler

As far as keeping track of what level you're on, there are several

Devendra,

Are you trying to create a web UI to manage AD accounts?  If so, I hope you 
know that you're reinventing the wheel.  Have a look at phpldapadmin at

The problem with PHP micro-optimizations like that or ' vs. " is that
PHP rarely bottlenecks a PHP/MySQL application (actually if you run a
dedicated box, see how often your CPU hits 100%, it won't be very
often for the vast majority of PHP/MySQL sites which are more likely
to be disk i/o bound than cpu bound).  The time spent in PHP (by PHP,
not by the database) for page generation is completely negligible and
invisible behind the overhead of network protocols for the vast
majority of sites or drowned in the performance killing of SQL.  I
would probably go so far as to say it doesn't matter how quickly your
PHP runs; you'd save as much time tuning one slow query as you would
micro-optimizing every line of your codebase.  Furthermore, the amount
of time micro-optimization takes up (going through old code, I mean)
could be better spent doing something that actually does increase your
performance, like implementing a search engine or memcached.  Going
forward, if you're aware that ++i and i++ are the same for your
application and ++i is a single php opcode faster (which I don't know
if it's even measurable, that difference), sure go ahead and use ++i
but it's certainly not worth serious thought or developer time.

If my memory serves, you're using PHP to generate the XML for Spry list using 
data from DB backend?  Or is your data in XML file(s) and not DB?

You could add a unique URL (based on product ID) of each product ID to row in 
the list.  The link would point to another page where your client can 
add/update the data.  Or if you really want to do AJAX way, clicking the link 
would show a hidden  for add/update depending on what link is clicked.  
Doing via AJAX means you'll have to add some javascript code of your own to 
tell Spry to refresh the data for the list and refresh the display results.

FYI, caching is messy when you may have concurrent users adding/updating the

I think you missed my point.

First, you do whatever you want -- do you whatever makes you feel 
comfortable. I'm not trying to change your ways at all.


Second, to the contrary -- all I am saying is if you have a 
preference in using ++$i or $i++, then use it. But to say the reason 
why you use it is because of speed is becoming less of an issue than 
it was. So much so, that for people to argue either side is rather 
pointless. There is no significant difference.


Sure we will continue to benchmark the speed of different languages 
for comparisons, we have a long history/habit of doing that. But that 
too is becoming less important than it was for what was significant 
yesterday is not significant today and will be even less so tomorrow.


For example, the Human Gnome Project was first thought to be a 
project that would take at least 15 years, but it was finished in 5. 
Why? Because the original projections were based upon the computing 
power of the day and didn't take into account advances in speed and 
memory.


So while we can debate computing considerations of today, tomorrow 
those will be less important. That was the point I was making. Why 
not focus on things that make significant difference and let the 
insignificant fade into history.


Look on the bright side, you can tell your grand children "I remember 
when ++i was faster than i++" and they'll wonder if Mom and Dad were 
right when they talked about putting you in a rest home.

I forgot to mention that in addition to the javascript code, you still have to 
validate and sanitize user input in PHP.  So might as well just have the link 
point to another page and do it there.  Upon successful update, you can 
redirect back the Spry list page.

Yeah, it's a valid as:

and does the same thing, which is nothing.

If you want a statement that does something, then use:

  $a = ++$a;

or simply:

  $a++;

or

  ++$a;

Any of those will increment $a, whereas ($a = $a++;) does nothing.

i think you can modify the PHP session handler without touching php.ini:
http://www.php.net/manual/en/function.session-set-save-handler.php

i've read a lot on the web about this in recent weeks. different people
offer their own justifications for the various approaches to session
handling: PHP's file handler, user DB methods for the PHP session handler,
PHP's memcache handler, zend session clustering, or do it yourself and don't
use PHP sessions at all.

there's a lot of controversy on the topic because different people have
different requirements and preferences. so your question WHY? is quite
complex.

my motivation for considering user DB back-end to the PHP session handler
was that it would replicate the session data over the DB cluster. retaining
the PHP session front-end means less code rework and you keep its session
locking. but it adds DB load, and the DB is often an app's bottleneck.
whether or not that's ok depends on app specifics.

i looked at memcache but i have two problems with it. one is that it is a
cache system so it's not designed to be reliable: if it runs out of memory,
restarts or crashes, the sessions are gone. the other is that the PHP
session implementation is barely documented. i couldn't figure out how it
implements the clustering (does it?) so i couldn't see how i would implement
failover, recovery and maintenance procedures.
http://phpslacker.com/2009/03/02/php-session-clustering-with-memcache/

one class i saw used memcached combined with DB in case of cache miss. it
speeds up the reads but every write goes to both cache and DB.

one thing that obviously helps is don't write the session to the DB if it
hasn't changed. i'm not sure how best to do that yet. and you can optimize
the writing of the session timestamp to the DB too.

then there's the question of whether or not to use one DB connection for
both session handling and the main app or use two connections. the latter is
easier to code.

row locking in the session table would be preferable to table locking.

maybe we should work together on the code for all this?

there's a webinar on zend platform session clustering that discusses various
issues, bearing in mind it's a technical sales pitch. i don't think it's
entirely fair to the DB methods.

Hello,

not...


I use name="submit" for the submit button instead, that will pass  
the

value of the submit button to the action script.

above all i use a template engine, smarty to take care of the
presentation for me(like deciding whether to show the form and/or a
success/failure message)


That only works if the user clicks on that submit button. If the  
user
hits the enter key in a text input, the form is submitted but the  
submit

input variable is not set. That is why an hidden input is a safer
solution.


If you need the button to be *clicked*...



Or something along those lines.


That does not make much sense and is pointless. First that syntax you
mentioned probably requires JQuery or some other large Javascript
library. something like this['submitButton'].click() would emulate the
click event. Second, by the time that onsubmit is called, the event  
that

triggered it was already dispatched. Emulating the click on a button
would probably fire the form submission and onsubmit code would be run
again, leading to an infinite loop sucking machine CPU.


It makes perfect sense and is not pointless. Yes, it is library- 
specific javascript. However, it was used to show an example and make  
a point. I assume that most the subscribers here are able to decipher  
the code and determine what the intent was. And no, this will not  
cause an infinite loop. The onsubmit is called first and will process  
whatever action you specify, and then move on. *If* the submit button  
wasn't *clicked* and you needed it to be, then this would emulate that  
functionality. I'm not saying this is the best solution on how to deal  
with the previous question but it is *a* solution.


Here's some code that you can see there's no infinite loop and shows  
which events are called first.

loop? i don't think so

Hello all,

I'm trying to display a div, only when some php value is set.
Since this will be near html, I'd like to keep it on one line. So, I'd love
to use shortcuts and a ternary operator for the effect.

I'm having something like this right now, but the div still appears even if

Sorry all,
It's ok. The sintax:

Anyway, I've learn something new: having a var with '' is not the same thing

Another one to consider...

strlen ($item) > 0 ? 'not empty' : 'empty';

Because "empty()" will return true if 0 is the value, sometimes you  
have to check for the length of the item.

I do micro optimization with every language I use, when I know, and where I 
can. I am the one that usually solves slow query problems, and I use best 
practices on database as well.

Guys, I don't get your point ... if you know that "$var" is a non-sense, feel 
free to use it ... what I know, is that every double quoted string require 
parsing, due to variable or char evaluations (\x00) evaluation, if I don't need 
this waste of time, why should I write a totally meaningless, useless, "$var" 
where $var is sufficient or more over 'whatever'.$var will be faster?

The fact is that this is my approach for every layer of an application, I am 
not like that only with PHP. There is something to optimize? Make it your code 
style and you won't spend a sinlge second more than any other, but at least 
you'll do your best to reach best performances.

As I have said, I have never had performances problem, and I am a full web 
stack developer, but you can obviously do whatever you want, is still a matter 
of points of view.

No; it's worse, because it can be interpreted in two different ways, which is 
demonstrated
by the fact that it gives different results in different languages.

According to Schlossnagel "Advanced PHP programming" it is better to use ++$a, 
because
this simply increments the variable, whereas $a++ makes a copy, and then 
increments the
variable, so it involves additional time and memory usage. I cannot see that it 
would ever
make a difference in the real world, but this is one of the tricks Schlossnagel 
advises
you should use when you want the fastest possible code.

Yeah, it's a valid as:

$a = $a;

and does the same thing, which is nothing.


No; it's worse, because it can be interpreted in two different ways,

That's true for different languages, but I was talking about php. In 
some languages even the variable $a wouldn't be legal.


However, you are correct that the confusion such assignments would 
raise would create problems as well.

Except that:

$a = 123;
$b = $a++;
echo $b;  //gives 123, not 124

as you logically expect it to and common sense would dictate, regardless of
what K&R or anyone else says.

that went into the final decision to include GOTO. It happened 2 or 3 
years ago and I was certainly on the side arguing in its favour. The 
GOTO used in languages such as C and now PHP, is not the bastard GOTO of 
BASIC yesteryear. There are certainly use cases where the use of GOTO 
makes far more sense than other constructs. Finite state machines (often 
used in parsing) are one such place. In fact if you grep for goto on any 
major open source project's C code, you will probably find multiple 
occurrences. PHP, MySQL, and Apache all use goto.


Cheers,
Rob.
