i just read, that objects in php 5 automatically returned as
reference? in my code it doesn't seems like that!!
ps: variable m_objData contains a lot of data from a mysql db
thanks for answers.
As you can read in some of the posts here, it only SEEMS like the
objects are passed by reference (it's a conspiracy!). I'm not sure if
it'll help you, but try using the ampersand (&) symbol to force
passing-by-reference.
Cheers,
Daniel
if i put de ampersand ( & ) everywhere, where it should pass as
reference, the script runs as longer as without ampersand.. its really
confusing !!!
...
"In PHP 5, the infrastructure of the object model was rewritten to work
with object handles. Unless you explicitly clone an object by using the
clone keyword you will never create behind the scene duplicates of your
objects. In PHP 5, there is neither a need to pass objects by reference
nor assigning them by reference.
Note: Passing by reference and assigning by reference is still
supported, in case you want to actually change a variable’s content
(whether object or other type)."
-> source: http://www.zend.com/php5/andi-book-excerpt.php
"Be warned, though—normal variables (i.e. those which aren’t objects)
are still copied (from my experiments with the beta), so if you need to
pass one by reference you still need to use the & reference operator."
-> source: http://www.sitepoint.com/print/1192
do u have a url to a document where this attitude/behavior is explained
for real, in detail?!

Raffael,
object in PHP5 _are_ passed by reference. internally, objects are
handles unique to a request, so all youre doing is passing a handle around.
note, however, that simple variable access will _always_ be faster than
method calls. this is true in C as well as PHP, except in PHP the effects
are more noticeable since it is interpreted rather than compiled.

Just to get things straight:
<?php
class Foo
{
public $foo = "bar";
}
$obj1 = new Foo;
$obj2 = $obj1;
$obj3 = $obj2;
$obj2 = NULL;
echo $obj1->foo;
?>
outputs
bar
while
<?php
class Foo
{
public $foo = "bar";
}
$obj1 = new Foo;
$obj2 =& $obj1;
$obj3 =& $obj2;
$obj2 = NULL;
echo $obj1->foo;
?>
outputs
Notice: Trying to get property of non-object in
/free1go/a/o/www.aoide.1go.dk/lab/bar.php5 on line 16
Hence, there is a difference between references and object handles. When
you pass by reference,for instance $foo =& $bar, where $bar is an
object, $foo will point to whatever $bar is pointing to. When you write
$foo = $bar, $foo will point to the same object as $bar, but $foo is not
forever bound to $bar, as in the first example. It simply has the same
object handle. Therefore, when you delete $bar ($bar = NULL), $foo will
be intact when using =, but will be set to NULL as well when using =&.

Daniel

This would be expected since each time through the loop, because
the first one has to call a method returning an object of which its
method is called returning another object of another method is then
called upon each time the loop iteration occurs, vs. the latter
where one method is called.

The code execution time, in your case, has nothing to do with how
the objects are being returned. You are calling several method()
calls to access one object within a loop, you're second way of
accessing the object is the more sensible way to approach this.

I wonder if anyone have come across a script/system that already has
this feature, else I would need to do it all over again. The scenario is
this :
I want people to select the movies they have seen and rate them 1/10.
Movies not available in the "polling" system they can add, and rate them.
This way the database is constantly growing, and ratings are constantly
added.
You can rate as many films you want, or noen if you like.
Then, after you have rated you can "match" your ratings to find other
people that match your selections. More like matching a profile really.
There would be some sort of system inside here which could build a form
of profile based on your ratings, and then compare theese profiles. I
havnt really started planning how this would work, or should work, but
first mainly if anyone has seen such a system around.
Looking for existing wheels... :D

This is usually due to header and library mismatch from my

did you try it with:
configure --with-gd
or
configure --with-gd=/usr/...
You can leave in the --with-jpeg-dir directives, it simply sounds
like you have mulitple versions (gd1 and gd2) on your system and
things are getting confused when it gets compiled.

Solved. The first transaction should be a PREAUTH, and the second
transaction should be a POSTAUTH. Linkpoint's documentation is
incorrect where it lists the possible transaction types. POSTAUTH shows
up as TICKET in the transaction report, but it doesn't work if you try
to send it as TICKET.
Nicely done, Linkpoint. Thanks to all for the help. :)

Solved. As suggested, the tech guy at EFS was on paint. The first
transaction should be an AUTH, and the second transaction should be
PRIOR_AUTH_CAPTURE, not just CAPTURE.
Thanks everyone for confirming there was no way what the guy said could
be true... :)

No, this is not a bug. This means that if you define a new constructor
/ destructor, the parent class's won't be called unless you put it in
the new ones.

Although not a bug, it is a little misleading, i've corrected it to
explain when the constructor isn't called.

I have ran into an interesting query performance problem that occurs
with both 4.3.7 and 5.0.1 against a MySQL 4.1 database. The test
program (attached below) works, but performance is extremely sloooow, a
perl version of the test program completes in less than 5 seconds with
80k records in table 1 and 138k records in table 2. The PHP program is
taking something like 1 to 2 seconds per record. This only seems to
occur when you have a query nested inside of another. My test program
attached uses mysqli, but mysql functions yield the same result. Any
ideas would be appreciated.
<?
$link = mysqli_connect("localhost","test","test","db");
$qry = "select a,b from table1";
$result = mysqli_query($link,$qry);
if (!$result) { echo mysql_error() . "\n"; }
while ($data = mysqli_fetch_array($result, MYSQLI_BOTH)) {
$sql = "select * from table2 where common=".$data[0];
$result2 = mysqli_query($link,$sql);
if (!$result2) { echo mysql_error() . "\n"; }

Is there some fundamental reason you're using nested queries instead of
a JOIN? PHP is generally slower in loops compared to Perl from the
comparisons I've seen, but the real issue is why are you using nested
queries to begin with...

My "real" application has inserts and does other various forms of
processing in the loops which cannot be done from pure sql via join,
etc. The test program I attached was just the minimum required to see
the performance issue. I agree that PHP is probably a little slower
that perl in loops, but not 5 seconds vs. several hours.

Say I have a form like ->
<form action="./foo.php?id=20" method="get">
...
<input type="submit"... />
</form>
If this form is submitted, the $_GET['id'] variable *is not* available.
If the method is changed to "post", the $_GET['id'] variable *is* available.
Is this how forms are supposed to work???
Thanks

Yes, when you use the GET method, the query string of the URL that your
browser requests contains the form data. I think you want to have
something like this in your form:
<input type="hidden" name="id" value="20" />
Hope that helps.

I have the following classes being inherited:
User extends School
I have two classes:
Profile extends User
and
Buddies extends User
being used in the same .php file. I get a "Fatal error: Cannot
redeclare class school in ..."
I can see why this is happening but three questions,
1. Does php5 allow for multiple extends? e.g. Profile extends User
extends School
2. Programmatically, how can I resolve this sort of issue besides not
using this class and making a new class with a different name?
3. Is there a way to uninclude a included file?
Thanks in advance.

I just got caught up on my mailing lists so sorry
about the late reply, but you could always start
charging cards when the order is ready to be shipped
instead of when the card is submitted to you.

Hi,
We recently upgraded PHP on our web server to version 4.3.8. After
upgrading sessions are not working properly. Please help to configure the
latest version.
There is a log-in module on our web site. After successfully entering the
log-in information, a session variable is created to track the user. But
this value is not carried while loading other pages. So it returns to
log-in module again. On the server , the session file is created (/tmp -
path for session files) and the values are also saved in the file. The
values are not retrieved properly by the following pages after log-in.
The same log-in module was working perfectly with the older version 4.3.2.
This is the LoadModule entry in the httpd.conf file for Apache.
LoadModule php4_module modules/mod_php4-4.3.8.so
Server Version
