[PHP] Object References Problem
Hi there,
I'm having trouble with passing objects as references. What I want to
do is something like this:
class object_1
{
var $my_chld;
var $my_array;
function object_1()
{
$this->my_array = array('id' => 0, 'name'=>'');
$this->my_child = new object_2($this);
}
}
class object_2
{
var $my_parent;
function object_2(&$parent_object)
{
$this->my_parent = $parent_object;
}
function set_parent()
{
$this->my_parent->my_array['id'] = 1;
$this-> my_parent->my_array['name'] = 'test';
}
}
$instance = new object_1();
$instance->my_child->set_parent();
echo "instance: ".$instance->my_array['name']."";
echo "parent: ".$instance->my_child->my_parent->my_array['name']."";
The above code give the output:
instance:
parent: test
where I want it to give:
instance: test
parent: test
but somewhere along the way, the reference to the parent object is
being broken.
I've looked all over the place, and I can't find the answer to this.
Can somebody please help me?
Cheers,
Gareth

Re: [PHP] Object References Problem
Boyan, Michael and Mike, Thanks for the help, I now understand what is going on, and you guys have saved me from pulling my hair out in frustration. I'm more used to doing OOP in Delphi and Perl, and the peculiarities of PHP are somewhat confusing. Once again, thanks for the help. On Friday, Oct 31, 2003, at 03:03 Europe/Amsterdam, Mike Migurski wrote: I don't pretend to fully understand PHP references, or the strange and mysterious ways that they work in regards to PHP objects, but I can tell you how to acheive the results you desire. Someone else will have to explain it. :) If someone sees that I'm leading Gareth astray here, feel free to jump in and correct me... Your explanation squares with my experience. My understanding from dealing with some fairly complex OOP interactions is that PHP operators generally favor passing-by-value to passing-by-reference, and the underlying language engine is optimized to perform well under those circumstances. Which is great, if you're new to programming, have never used Java or C, and are tossing arrays around and don't want to be bothered with premature optimization, but it's a royal pain when you need to maintain some degree of referential integrity. I frequently find myself using '&' all over the place to cut down on accidental returns-by-value. I have not yet had a chance to play with PHP5's beta versions, but its strong focus on OOP makes me wonder, what kind of language changes (if any) were required to help ease this situation? -mike. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] using existing mysql connection in a php extension
Hi there,
Try this:
mysql_pconnect($_host, $_user, $_password) or die("Could not connect:
" . mysql_error());;
This open a permanent mysql connection. The first time you run it, it
opens the connection, and the second time, etc, it just uses the one
already opened.

because if i have to connect to the mysql server again from my

Do you see any information in your browser before the error appears?
Perhaps you could also do a view source from the browser to see if
anything has been sent out.

Here is what I have:
1. An index.php that inculdes products.php if $file=products.php.
2. products.php includes db.php that contains databse connection and
the

3. When I click "add product" $file=cart.php and cart.php includes the
db.php file that should connect me to the db and check if there is a
session.
It works fine if I go passed the index.php file. Maybe it is because
the
index.php file has echoed information. Any idea

Re: [PHP] Moving to php
hi there, I suppose that technically PHP is built to run on Linux, but does work on many other platforms. I do all of my development on OS X and have never had any problems, I've also had it running on Linux and FreeBSD without any trouble. I think there is no problem with Win2000, but I don't use that, so I can't give you a definitive answer there. From what I've read about the move from 4 to 5 backwards compatibility will not be a problem. MySQL works fine with PHP, as does PostgreSQL, and loads of other databases. cheers, Gareth On 16 Nov 2003, at 14:21, Jim Van Heule wrote: I'm seriously considering moving to php from a competing 3rd party application. I have a few basic questions. 1. What is the predominate OS platform php runs on? Recommended? 2. I'm currently well versed in Win 2000 & OS X. Are both "Well" supported? 3. When php comes out with a new major version (i.e. php 4 -> 5), how backward compatible is it? Basically, will I need to do a lot of recoding each time there is a new version in order to upgrade?

Re: [PHP] How to optimize select of random record in DB ?

If the table is large, then the following might be better:
LOCK TABLES foo READ;

SELECT * FROM foo LIMIT $rand_row, 1;
UNLOCK TABLES;

This doesn't verify that the portion following 447 is also a number.

Hi All,
What are the rules of thumb for classes and included files?
Can I not include a file in a class function? If I put the include()
outside the class structure everything works fine, but when I put it
inside
the class it freaks.
Am I doing something wrong?
Class myclass{
Include('myfile'); -- doesn't work
Funciton myfunc($var1, $var2){
Include('myfile'); -- doesn't work
}
}
But,
include('myfile'); -- works
Class myclass{
Funciton myfunc($var1, $var2){

Why?

Re: [PHP] Paginate any query
Hi,
In your mysql query, use the LIMIT keyword at or near to the end of the
query.
LIMIT 1000 will limit to the first thousand records
LIMIT 2000,1000 will retrieve 1000 records, offset by 2000 records.

I'm guessing this is a bug, but I'm wondering if any one has a work

Re: [PHP] 2 OOP or Not 2 OOP

Re: [PHP] Confused with constructors

function base_object()

echo "I'm the base";
}
function base_test()
{
echo "I'm the base test";
}
}
class extended_object() extends base_object

function extended_object()

$this->base_object();

function extended_test()

Barring any syntax errors (I wrote this out of my head), this should
show you that the base object is being properly constructed.

Running this on 4.3.9 both as an apache module and

I am a regular function named B in class A.
I am not a constructor in A.
This is contrary to what the manual says:
"This is fixed in PHP 4 by modifying the rule to: 'A
constructor is a function of the same name as the
class it is being defined in.'. Thus in PHP 4, the
class B would have no constructor function of its own
and the constructor of the base class would have been
called, printing 'I am the constructor of A.'."
Is this an error in the manual?
Or a bug in php 4.3.9?
Or just me being stupid?

Re: [PHP] For Loop
What happens is (if I understand it correctly):
First, PHP sets $i to equal 0, and then immediately sets $i to
$months_arr_length.
Every time the loop executes, it resets $1 to $months_arr_length, so
you are stuck in an infinite loop.
The reason behind this is you are using assignment equals (=) instead
of comparison equals(==). It's a mistake I've made myself quite a few
times.
As an aside, a neater way of using a for loop on an array is the
following:
foreach ($months_arr as $key => $value)
{
echo $value."";
}
On 8 Dec 2004, at 22:41, R. Van Tassel wrote:
I have a question about the following code:

$months_arr_length = count($months_arr);
for($i = 0; $i = $months_arr_length; $i++){
echo $months_arr[1]." ";
}
***
When I run the code above it continues and never stops. According to
the PHP
documentation the second condition works as follows:
"In the beginning of each iteration, expr2 is evaluated. If it
evaluates to
TRUE, the loop continues and the nested statement(s) are executed. If
it
evaluates to FALSE, the execution of the loop ends."
In the first iteration of the loop $i would equal 0 and the array
length is
12. 12 is consistent. To it seems that the loop should STOP when the
counter
reaches 12, equal to the length of the array. Why is it continuing in a
neverending loop? What am I missing?
Changing the condition of the for loop to $i <= $months_arr_length;
fixes
everything and it works properly.
Can someone please explain where my confusion is?
