glad my posts are useful ;)
anyway, you can register a channel on any server, so you dont have actually
to run one by yourself, there are zillions of networks out there that are
just waiting for you. you can also check pjirc, it is a jave applet for
online irc chat, its pretty integrate-able, you can change the background
and the whole look to feat your website, also the language, even Hebrew is
supported :D
HTH,

Are there any examples of creating a dll that can be placed in
the dll directory of php that can be accessed by php? My
language would be Delphi, however an example in C would suffice.
Many thanks...

Custom PHP extensions. I don't know of any Delphi-specific examples,
but this link might give you a starting point:

I have this line of code:
$q = "This is the string that will go into the query:
{${mysql_real_escape_string($_GET['searchstring'])}}";
What happens then is the user supplies 'foo' as the search string, and I get
a debug notice "Undefined variable: foo". Why is it treating the value as an
identifier and how do I make it do what I actually want it to do? This is on
PHP5, latest release.

Why exactly are you doing this? While variable-variables can be of use
at times, I don't think this is one of them. How do you use this newly
created variable.

Subject: [PHP] Complex escape string
I have this line of code:
$q = "This is the string that will go into the query:
{${mysql_real_escape_string($_GET['searchstring'])}}";
What happens then is the user supplies 'foo' as the search string, and I get
a debug notice "Undefined variable: foo". Why is it treating the value as an
identifier and how do I make it do what I actually want it to do? This is on
PHP5, latest release.
---------------
It looks to me like what is happening is this piece:
${mysql_real_escape_string($_GET['searchstring'])}
Gets collapsed to $foo when mysql_real_escape_string($_GET['searchstring'])
== 'foo'. ${'a'} will expand to $a. I think that your problem is that you
need to drop that '$' before the brace around the function call.

I have a quick question on what's coming in PHP 6.
I've incorporated use of the ability to call instance methods through
static calls, allowing for me to mimic multiple inheritance without
having to make edits to classes that are already working because of
the behavior of '$this' when instance methods are called statically.
As stated on in the basics section on classes and objects:
"$this is a reference to the calling object (usually the object to
which the method belongs, but can be another object, if the method is
called statically from the context of a secondary object)."
I've made great use of that functionality in my framework. However,
It sounds like this is going to cause a fatal error in PHP6. Is this
in fact true? And, if the behavior is going to change, can somebody
explain what the impetus for this change was?
Thank you very much for your time,
Adam

I am trying to load PHP objects stored in a database, where the class
name is stored in a column:
$object = new $resultSet->getString(1);
This fails for the same reason that the following fails:
<?php
class Foo
{
public function className()
{
return 'Foo';
}
}
$foo = new Foo;
$bar = new $foo->className();
Fatal error: Class name must be a valid object or a string in test.php
on line 12
I guess this error is due to the confusion of parsing "()" as the
argument list for the "className" function, or the "Foo" constructor...
I work around this error by using a temp variable:
$tmp = $foo->className(); $bar = new $tmp;
- however the above reads like hacky code : (
When calling dynamically named functions, I generally use
call_user_func() to avoid awkwardness with $object->$tmp($arg1, ...)
In other words, I prefer:
call_user_func(array($object, 'get'.$someName), $arg1, ...);
- to:
$tmp = 'get'.$someName; $object->$tmp($arg1, ...);
However there does not appear to be an analog of call_user_func() for
constructing new instances of dynamically named classes?
If I recall correctly, there was also a way to work around calling
dynamically named functions (e.g. $object->$tmp($arg1, ...);) using
curly braces:
$object->{'get'.$someName}($arg1, ...);
- however I cannot recall the exact syntax.
Can anyone confirm that there is a curly brace syntax for calling
dynamically named functions? Could it be applied to instantiating
dynamically named classes?
Can anyone recommend a cleaner alternative to:
$tmp = $foo->className(); $bar = new $tmp;
Thanks and best wishes, Jack
