I used to work for a fairly major chat site that used software by iChat
to push slides -- and I'll be darned if I could figure out how they did
it. Some weird quirk of HTTP, I'd think.
Anyway -- getting a basic socket server up in running in the language of
your choice and using something like flash as a front-end is actually
not that hard. It seems to me that, in a lot of cases, PHP is the wrong
tool for the job when there are others out there that do it really well.

I am fascinated by the PHP Live! Support Solution
(http://www.phplivesupport.com). I would like to try to replicate this
functionality just to see how it works and maybe use it on my own
website. Does anyone know how they accomplished server push and real
time chat?
I am aware or some different techniques such as <meta> refreshing (which
is really more client pull). I highly doubt this is how they
accomplished this. There is also sockets, which opens a possible
security concern, so I doubt they use that either.
I was thinking of using web service based on nuSOAP that simply checks
the database for new "messages". That closes the port because it is a
web service. But can this be done? Is there anyone that is familiar with
what method was used for real time chat/server Push? ESPECIALLY in PHP
Live!? I would really like to here some different thoughts and
techniques.
I have looked at some open source versions, but the ones I looked at all
used <meta> refresh. (They where also very slow).
Thanks everyone!

You are right, but I need to implement a solution that avoids accessing
to disk.
The context under which I’m running now has not a huge database, but it
increments it’s size quite fast.
I must say that for that reason is that “many many updates” are made.
Also when one user gets a page much information should be shown.
The “good thing” is that this (shown) info does not need to be 100%
accurate (I can show information that is 15 minutes old without problem).
I would like to have this kind of intermediate PHP process in order to
serve these requests of information instead of accessing the database to
collect it (as far as I’m experiencing some disk bottlenecks).
Then the PHP process each "n" minutes or "m" requests refreshes the info
and present it on demand.
Here the reason for trying to implement this """layer""" (if it is
possible, +-easy and/or fast)
Thx again

Sounds like a pretty run-of-the-mill storage issue; or did you want to
save XML messages? In any case, storing the information in a session is
probably the easiest and most straightforward way to do this. Or store
the information in a database.
Jason
--- End Message ---
--- Begin Message ---
If you're trying to prevent hitting the database then just cache the
page result and store it as a temporary html file. Then serve the
temporary file whenever people visit (and update every 15 minutes).

If you only need to persist a handful of request-agnostic variables you may
be able to make use of an extension I wrote. Note that it doesn't work under
Windows and I haven't tested it under PHP 4.3.x.

If you use ISSET together with a hidden field when posting a form to itself
to enter a second-state, is there a way of using it again to get to a
third-state.
Basically, I'm trying to convert a 3 file script into a single file and
first I check to see if it's been submitted and then using ELSE I echo out
the second form. But how do I use isset again?
Do I need to unset the variable from the first stage of the form? If so, how
do I do this and prevent the form going back to the first form state?
I've had the script working with two states but can't get the third state
working!!!
Any help or alternative ideas much appreciated as this is causing me a
serious headache!!!

Hi,
I tried to use my own error handler to handle all non-fatal errors. But
to my surprise it seems to be impossible to handle E_STRICT level
notices. I don't know whether this is by design, not yet implemented or
a know bug that I overlooked - but it seems rather strange :).
To reproduce:
- create your own error handler
- set error_reporting to 0
- generate a E_STRICT notice, for example by using var $x as a class member.
Your error handler won't give a sound!
Anyone an idea?

Jason,
Please read my question a bit better :).
PHP indeed does report the E_STRICT notices fine, that's not my problem.
I know how error handling in PHP works :).
But I have my own error handler (see: set_error_handler()) and handle
all notices and warnings myself (and all other E_USER_* of course). And
I was wondering why errors of the level E_STRICT don't make it to my
custom error handler function, in contrast to for example E_NOTICE.
Didn't expect to have to explain this here :(.

var $x, E_STRICT error occures at compile time so it wont be able
to be caught.
On the otherhand, dl() throws a E_STRICT at runtime but the error
handler still doesn't get called.

How do I check for the presence of an optional $_GET param without

Tried all three of these, they all produce the Notice when the param is
not passed:
if ($_GET['id'])
if ($_GET['id'] != "")
if (isset $_GET['id'])
isset should *not* be throwing a notice, that's what it's for. Try using
parenthesis.
if(isset($_GET['id']))

So I'm trying to implement a simple wiki-like syntax for hyperlinking.
Basically I want to match stuff like [this], where the word 'this' gets
turned into a hyperlink. I have that working, but I want to be able to
escape the opening bracket, so that it's possible to do \[that] without
having it match as a link. Here's what I've got:
// Matches fine, but without escaping
$pattern = "
/
\[ # Open bracket
([^\]]+?) # Text, including whitespace
\] # Close bracket
/x
";
// Throws an unmatched bracket warning
$pattern = "
/
[^\\] # Don't match if a backslash precedes
\[ # Open bracket
([^\]]+?) # Text, including whitespace
\] # Close bracket
/x
";
// Ignores escaping: \[example] still matches
$pattern = "
/
[^\\\] # Don't match if a backslash precedes
\[ # Open bracket
([^\]]+?) # Text, including whitespace
\] # Close bracket
/x
";
Nothing seems to change if I keep adding backslashes to that first
matching thingy (i.e. the escaping still doesn't work). Any ideas?
Thanks much,
-Dan

Please don't spam the list, we saw the message the first time. Well in
order to run the application on a pocket PC you'd need a PHP binary for
your specific platform (I don't know if there are any already out there,
but I think you can build it from source yourself if need be). Also,
you'll need PHP-GTK (PHP-GTK2 is supposed to be for PHP5, not sure about

Since you're invoking this as a static method the only solution that
comes to mind is to use the PHP5 builtin class Reflection_Method and/or
Refelction_Class. Perhaps something like:
<?php
Class Test {
function Test() {
echo 'Test';
}
}
Class MyClass extends Test {
function Debug() {
print 'Hello MyClass';
}
}
$reflection = new Reflection_Method('MyClass', 'Test');
echo "The declaring class is: " . $reflection->getDeclaringClass()->name;
?>
For a good overview of what you can do with Reflection_Method, see:

http://php.net/require
http://php.net/include
require() and include() are identical in every way except how they
handle failure. include() produces a Warning while require()
results in a Fatal Error. In other words, don't hesitate to use
require() if you want a missing file to halt processing of the
page. include() does not behave this way, the script will continue
regardless. Be sure to have an appropriate include_path setting as
well.

with a 1 such as 1variable. Nusoap loads the variable descriptions from the

Since PHP5 is going to feature OOP (Object Oriented Programming), will that mean PHP6
will feature AOP (Aspect Oriented Programming)...so far it seems AOP is only being
used for Java at the moment; but hopefully general programming and scripting languages
will start using them as well?!

I don't know what do you think OOP is but PHP supports it since PHP 3.
AOP is not a feature of any language but rather an artifact to add or
remove code that implements certain aspects. This usually requires a
compiler or a code processing tool to enable the aspects you are
interested. There is nothing in Java that makes this possible that would
not be possible in PHP.
As a matter of fact there is an Aspect Oriented Programming tool named
Metastorage that generates DAO (Data Access Object) classes that lets
you control which aspects you want to build into your DAO classes. For
instance, if you do want a function in the generated classes to delete
objects, you have to explicitly request it. Otherwise the class will not
feature that aspect. This leads to much more optimized code that does
not feature aspects that are not needed.
This tool generates code that runs on PHP 4 or better. You may find more
about it here:
