Dear
I have problem with writing large data (large text) in the database or any file
.
If we try to do, the field in the DB or the file will be empty . (We lose the
data) .
I mean by large data more them 60 Kbyte .
But if we try to write small text (less then 60K) , the text will be added
normally in the DB or in the files .
Knowing that all settings are good :
max_allowed_packet=10M
; Maximum size of POST data that PHP will accept.
post_max_size = 8M
And the DB accept large text normally .
Do you have any Idea how we can solve this problem ?
Or is there any setting i must change it ?
What type of db is it (mysql, pgsql, firebird) ?
What type of field (text, varchar, char, blob) is the one you're trying
to write to?

Hi,
Too lazy to actually read the email (tsk), but there's rather a nice
paging library in PEAR that may help. Imaginitively called "Pager".

Works fine for me, probably because my copy of Notepad
is so old it has never heard of Unicode...
Here's another test:
echoUTF8.php:
-------------
<?php require 'echoUTF8sub.php';
echoUTF8sub.php:
----------------
<?php echo "\xef\xbb\xbf", "test\n"; // Manual BOM
When I run this from a browser, I get different output
depend on the server's and browser's default charset,
and PHP's "default_charset" setting.
I get consistent results when I add
header ('Content-Type: text/plain; charset=utf-8');
to echoUTF8.php.
(When the scripts are run from command-line, the output
would also depend on the shells ability to handle utf-8.)

I don't think that PHP is good language for teaching OOP as many folks above
said. I have never programmed in OOP style but i plan to learn it. I started
in PHP but i was little confused and i am used to program in procedural way
in PHP, so i've decided to learn some pure OOP language. I am reading a book
OOP Demystified, there are examples in both C++ and Java. And imo Java code
is much more readable and understandable. So i think that Java is the best
for learning OOP. I am also considering learning C#, if you dont mind that
it's closely related to windows, it might be also a good choice.

For teaching programming or OOP I would choose a language which
concentrates on the topic. The hard stuff, which you have to deal with
in C for example, can be learned later. I'm glad that I started
programming in Pascal, not in C. If today I had to learn programming as
such I would definitively opt for Python! My choice for learning OOP
would be Python or even better Java cause you don't have the choice to
do it in a procedural way.

Where I study, Intro to OOP is taught in C# using Visual Studio 2003 and
further OOP concepts are taught in Java, with the academic computer science
of OOP alongside.

Yes, it is, but the original question was about OOP and not
specifically about PHP. It seems fair enough to me for someone to ask
the question on this list since PHP was one of the languages being
considered, even if consensus among the list seems to be that PHP
would not be the best choice for teaching a course on OOP.

Hi,
I'm just getting into programming in an Object Oriented fashion, and am
looking for some guides, tutorials, hints, tips, etc...
I only just found out that you remove the $ from variables when calling
them from $this->
e.g :
<?php
class People
{
private $person = "not set";
function __construct()
{
*$person* = "A person"; //This doesn't work (well it creates a
variable $person that only has the scope of the current function from
what I can gather)..
$this->*person* = "A person"; //This works properly
}
function display_list()
{
echo $person; //This doesn't work
echo $this->person; //This works.
}
}
$person= new People;
$person->display_list();
?>
Instead of painstakingly working out most of the other mistakes I'm
likely to make, I'd love to read about other peoples issues they had
with learning OO so I can skip most of the hard stuff, and only make
small mistakes (hopefully).

Ok, because it's you I'm going to offer you this ebook at the very
very very low limited time price of $49 and I'll throw in a free
watermelon.
Ahh, hell, I can't be arsed. It's in the frickin' manual: http://php.net/oop

Alrighty, so I went a different route...
I created my own ActiveX DLL...one that I know I can register.
Starting out really simple:
//My VB code
Public Function hello() As String
hello = "Hello World!"
End Function
//My PHP code
<?php
function Hello() {
$new_com = new COM("DMStoTIFF.conv");
$output=$new_com->hello();
echo $output;}
Hello();
?>
So, after I register the DLL on the server my PHP page is correctly
displaying the "Hello World!" dialog.
What I'm having problems with now is trying to pass a variable to the DLL.
Shouldn't I be able to do this just like any other PHP class/function?
