Re: [PHP] call to a member function select() on a non object.
you already had the answer to this problem. do try to read the error message
properly.
a 'non object' is quite clear - if in doubt about what something is or something
should be use var_dump() or print_r() to output the variable in question (e.g.
$DB, which
you would have seen was NULL).
now for some tips ...

don't store these in the class - it makes the class usable

be reusable.
instead pass in these connection parameters to the constructor

mysql_select_db($this-db_name,$this-link) or die(ERROR:

the 'or die(bla bla);' type of error handling is rubbish, you can
use it for simple/throw-away scripts but when your writing a class
you should make the error handling much more flexible and leave it
up to the code that uses the class to decide how to handle the
error. with the die() statement the consumer of the class has no choice
about what to do if a connection error occurs.

IIUC the yet to be released garbage collection improvements will potentially find/destroy unused zvals sooner (as well as being better in sorting out defunct circular references etc) but that the garbage collection itself uses a certain ammount of cpu cycles and in short running scripts (e.g. most of what we write for the web) it's likely to be better to let php just destroy memory at the end of the request. that said your more cautious approach cannot hurt :-) PS - my apologies if the memory related terminology I've used is somewhat bogus - please put it down to my lack of proper understanding :-/ -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Christoph,
if you dont want to write a function in the global namespace, as suggested
in the article, Eric posted, just add a simple factory method in your class,
eg.
?php
class Test {
public static function getInstance() {
return new Test();
}
public function doSomething() {
echo __METHOD__ . PHP_EOL;
}
}
Test::getInstance()-doSomething();

Re: [PHP] potentially __sleep() bug
Nathan Nobbe wrote:
all,
i was playing around w/ some object serialization tonight during
further exploration of spl and i stumbled on what appears to be a
bug in the behavior of the __sleep() magic method.
here is the pertinent documentation on the method
..is supposed to return an array with the names of all variables
of that object that should be serialized.
so, the idea is, *only* the instance variables identified in the array
returned are marked for serialization.
however, it appears all instance variables are being serialized no matter what.
see the reproducible code below. ive run this on 2 separate php5
boxes, one w/ 5.2.5, another w/ a 5.2.something..
?php
class A {
public $a1 = 'a1';
public $a2 = 'a2';
public $a3 = 'a3';
public function __sleep() {
echo __FUNCTION__ . PHP_EOL;
return array('a1', 'a2');
}
}
var_dump(unserialize(serialize(new A(;

this is what i get despite having marked only member variables 'a',
and 'b' for serialization.
__sleep
object(A)#1 (3) {
[a1]=
string(2) a1
[a2]=
string(2) a2
[a3]=
string(2) a3
}
consensus ?
To check if __sleep is proper, you should be doing
var_dump(serialize(new A()));
unserialize'ing effectively also does a __wakeup()
This should give a clearer picture
?php
class A {
public $a1 = 'a1';
public $a2 = 'a2';
public $a3 = null;
public function __construct(){
$this-a3 = 'a3';
}
public function __sleep() {
echo __FUNCTION__ . PHP_EOL;
return array('a1', 'a2');
}
}
var_dump(unserialize(serialize(new A(;
?
__sleep
object(A)#1 (3) {
[a1]=
string(2) a1
[a2]=
string(2) a2
[a3]=
NULL
}
= and ==
?php
class A {

not exactly - 'new' asks php to initialize an object of the given class,
the 'binding' to a variable occurs because of the assignment operator. the
__construct()
method is called automatically by php after the object structure has been
initialized, so primarily
nothing is returned because the call to __construct() doesn't happen directly
in userland code.
at least that's how I understand it.
So, constructors return nothing.

well you are still creating an instance of the object. the only difference
is
you are forcing it the ref count to 0 by assigning the instance to a local
local variable.
It's fairly likely that I'd actually just use a static method here,
both your and my code use static methods. it sounds to me like you are
using the term 'static method' to mean a static method that has a variable
with a reference to an instance of the class that it is a member of. which
is obviously a particular use of a static method, and therefore a bad
practice
imho. not the technique, mind you, the label of 'static method' for the

[PHP] php spanish character problem
hello everyone,
This is important,I am trying to post some spanish characters from a form on
a page and i am comparing those spanish characters to the same letters on
the same page but on strcmp the return is not zero.I don't know what is
wrong some problem with the post method i guess or strcmp i don't
knowPlease helphere is the code...
htmlbody?php
echo(strcmp('í',$_POST['check']));
?
form action=./index.php method=post
input type=text name=check
input type=submit name=go
/form
/body/html
the name of the file is index.php and i am typing í in the text box before
pressing submit.the result is not coming as zero but -1.The result is not
coming for any of spanish or special characters like ¿,ñ,ü how to solve it
that echo answer is zero.
I have searched a lot on net and finally i am coming here to get some help.

i dont think Registry::getInstance() is really that much overhead;
In my initial tests I found that static methods accessing $GLOBALS
directly was much faster than using an instance and working on it
tucked away in a static variable. The getInstance() to pull and check
against the existence of the instance and creating it really added a
lot of extra code execution.
I use the intercept filter pattern on my code execution so that I can
set up different filters for authentication, authorization, gzip
output buffering, session management, etc based on my page needs. I
then wrap that around a front controller. So the registry has been
key in being able to push and pull data from many different scopes.
Then again sometimes I just use include files like the php patterns
site recommended[1].
Up until the start of this year my company was stuck in PHP4 since in
the real world clients don't want their sites to break because people
want the latest and greatest. :) A big reason I've had to dig around
is because I want to use the best ideas yet be able to run them on 4.
Now that we have 5 running everywhere it might be an option to
re-visit and use a fluent interface to do something like:
registry::getInstance()-get('foo');
I'd store the getInstance() instance in some sort of protected self::
accessed property and return if it exists or not. Maybe when I get
some free time I'll do a benchmark to see how nasty that is versus
just using static methods.
PDT hasn't ever crashed on me, but now that I've typed that... ;D

Now this is clear.
But to point out in the code I quoted, you said that you were going to only use
the static method, but you were calling the static method that created an
instance of the Test class and then calling the non-static method from the
instance of the Test class.
Your previous example was not showing us what you were saying. To me it looked
like you were confused about how you were calling/creating things.

here is a mod of the code you posted w/ a var_dump() of the

?php

clearly in the act of *just* using a static method, you *just*
created an instance of class Test ;)
Ok, I'm going to have to assume you really are as stupid as you seem.
If I need to provide an example to demonstrate what I meant I will,
but I feel I made it quite clear that my comment regarding what *I*
would do did not in any way relate to the code example I had provided
above. The example I provided was fulfilling the OP's requirements.
This is what *I* would do...
?php
class Test {
public static function doSomething() {
// I'm assuming this method is fairly complex, and involves
// more than just this method, otherwise there is no point
// in creating an instance of the class, just use a static
// method.
// See this comment here, this was taken from the

// I meant when I say just use a static method.
}
}
Test::doSomething();
?
Look ma, no instance.
Now this is clear.
Glad to hear it.
But to point out in the code I quoted, you said that you were going to
only use the static method, but you were calling the static method that
created an instance of the Test class and then calling the non-static
method from the instance of the Test class.
I thought the comment in that static method explained that I didn't see
the point in creating the instance. I thought it was pretty clear, but
clearly not.
Your previous example was not showing us what you were saying. To me it
looked like you were confused about how you were calling/creating things.
I was never confused! ;)

ok it's not for everyone, certainly not for me. but what is it from your
point of view that makes it a 'more interesting advance'?
1) Test driven development is built-in, and not just unit tests, but
functional tests and integration tests too. In addition there's
several plugins that extend your tests into realms you may not have
thought of. There's Rcov which will tell you what code you haven't
written test for. I know, you don't write tests. It's perfectly
natural to not write tests when your framework doesn't support them
out of the box.
2) Prototype and script.aculo.us are built-in. Not just included in
the download but fully integrated into the models.
Symphony tried to pull off the same thing with it's framework but it's
fairly messy in my opinion.
update_element_function('foo', array(
'content' = New HTML,
));
Compared to the Rails equivalent:
page.replace_html 'foo', :html = 'New HTML'
The other Javascript helpers like observers for example are similarly
very small.
3) Database migrations that allow for versioned SQL. I can roll out
new sql or roll back my broken sql with a single command.
rake db:migrate VERISON=42
I can rebuild my entire database from scratch:
rake db:migrate VERISON=0; rake db:migrate
The migrations are Ruby code that are very tight in syntax:
class CreateSessions ActiveRecord::Migration
def self.up
create_table :sessions do |t|
t.string :session_id, :null = false
t.datetime :updated_at, :null = false
t.text :data
end
add_index :sessions, :session_id
add_index :sessions, :updated_at
end
def self.down
drop_table :sessions
end
end
4) Capistrano which is fully integrated with Subversion (and soon Git
I heard) allows me to roll out a versioned copy of my application with
a single command:
cap deploy
And then I can also rollback just as easily in case of an error:
cap rollback
5) Ruby on Rails has a built-in plugin architecture for adding vendor
code. I can add new functionality to my app as easy as
gem install acts_as_taggable
or
gem install pagination
It's a bit like Perl's CPAN if you're familiar.
There are also plugins, engines, and components depending on the level
of integration you want the vendor code to have.
6) Model validations extend into the view. No re-mapping of variables
like with Smarty or some others I've tried.
7) The REST architecture is built-in to Rails. No more SOAP, unless
you want it of course. No one's using it but it's there.

SPL's main drawback for me personally is carpal tunnel syndrome, I don't have it and I don't care to acquire it. i sortof enjoy having php on the backend and javascript on the client side. it lets be bounce around between paradigms. as per the ruby / prototype integration, i will say, that is one nice component, that i actually use all the time now. infact, im on the rails-spinoffs mailing list where we discuss prototype. i read a book, 'prototype and scriptaculous in action'; learned a ton of course. nowadays, my webapps have the web 2.0 buzz. but as far as the generation of javascript on the server side, i still have mixed feelings. the case made by rhino is, your favorite java editor, your current java debugger and you dont have to learn another language. well, i suppose the case is somewhat similar for the rails / prototype integration. javascript is actually quite a complex language and its funny because people will always say things like, its such a nice 'little' language. if youre not familiar w/ functional languages w/ closures and so forth, anonymous objects and functions, etc.. javascript can be really confusing! i would extend this as a good reason to understand the language. but what a hippocrate i am, since im using propel to get away from sql :) to each his own, indeed. what id like to know, since you seem to know so much about the ruby on rails framework, is, what sort of debugging support is there? this is a weak spot in php to be sure. ive tried multiple clients w/ xdebug w/ marginal success at this point. -nathan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Contrary to what you may think, `emerge -uND` is not an upgrade path, at least not for a serious server deployment.

I've tried getting the sum() from the MySQL table, but Multiplier is
either at
1 or 2 or 2.5 and the only way I can get an accurate total consumption
is
getting the sum from the results.
You should be able to use:
sum( (Reading + KwHrAdjustment - Reading1 + KwHrAdjustment1) /
$noofdays * Multiplier) from MySQL in another query...
But if you are already iterating through the results anyway, it's
probably just as easy to do:
$sum = 0;
while ($row6 = mysql_fetch_assoc(...)){
$consumption = $row6['Reading'] + ...;
$sum += $consumption;
}
echo Total: $sumhr /\n;
Is there a way I can place this code on an array? I've tried using
$indcons = array( sprintf(%1.2f, $row6['Reading'] + $row6
['KwHrAdjustment']) - ($row6['Reading1'] + $row6['KwHrAdjustment1']))
/
$noofdays) * $row6['Multiplier']))) but I've obviously failed.

Your script is reading the whole file, 64 measly bytes at a time, into

If you want a timeout on the opening, the setting is in php.ini, or you can just use ini_set() right before the fsockopen. In (1), how is the timeout applied - is it: a) timeout includes the entire curl_exec() call - the combined socket write() ( to send the request ) and the read() ( read the response ) calls. or b) timeout is independently applied to write() and read() end respectively. Some of our tests seem to indicate it is (a). You'd probably have to ask the cURL folks... In (2), I am assuming the stream timeout is applied at each i/o call independently for fwrite() and fread() - I am pretty much certain on this as this is how it would map to underlying C calls. Almost for sure, it applies to any given fwrite/fread. Actually, probably at an even lower level, to any given packet sent/received within an fwrite/fread It will be good to get a confirmation on our doubts. -- Some people have a gift link here.

Re: [PHP] php embeded in html after first submit html disappear
Hi Jochem,
Thanks for the prompt response. No I do not want people to fill in both
forms at once.
I actually have a three step process. I simplified it to two because if I
can get two steps to work, I should be good to go. Each step depends on the
preceding step having completed successfully. Users therefore need a
success message after each step is successfully completed. We cannot
require that users do all steps in one sitting. It must be possible to do
step one, leave, come back the next day and do 2,etc.
Because there is not enough to each step to justify a full web page devoted
to it alone, I have decided to keep all steps on one page.
Is there any way to use the hidden attribute of HTML variables to prevent
the output message from overwriting the page?
