Re: [PHP-DEV] Can we call Apache 2 API function from a PHP 5 extension module?
yep nevermind I don't you post this question on php-internal and don't
understand this ugly suggestion, Brian when I read your cv it seems to
be something serious ... when I see the line with your type recasting
I am not sure you understood something during these 15 years.

Try this instead:

Apache 2.x server_context is not a request_rec, it is a struct with a request
rec in it.

Re: [PHP-DEV] __toString(), __toArray()
I am not forcing anything, it's already there, that's definitely a
more useful magic, if people would add a new one, __cast is not
critical, catchable objects are __catch even if exists, so my point I
'd rather see useful requests than a unseful one e.g __cast
from my perspective __toString and __toArray , __callStatic should be
removed __callStatic is definitly a mistake.

I agree, moving all magic to a single function doesn't help the situation at
all, it simply complicates it.
All this talk of too many magic functions is a little comical, its all
trying to overcome operator overloading type functionality in other
languages.
__get()/__set() would be equivalent to getters/setters supported by the c#
language
__toString(), __toArray() would be equivalent to operator String() in c++ (
if I remember correctly )
I would definitely love to be able to, at the very least, cast an object to
an array but I figured a more general purpose __cast() would be most
beneficial to all.
I think the ambiguity question for some functions accepting mixed as a
parameter type could be solved in aforementioned ways.

I know there's been requests to add a __toArray() and most of the
arguments
against it is that there are too many magic functions already. I just
thought I'd propose an alternative that would satisfy all of them.
Why not a __cast($Type) magic function?
I'd advance two reasons against this idea:
1) It's more self-explanatory to explicitly call the appropriate
converting method, enough with implicit madness!
2) For some operations, you'd have to know the types in advance before
knowing what operations needs to be performed:
$obj1 + 2;
Now what __cast should be called? Int? Float?
Wouldn't it make sense to be an integer since its being added to an integer?
Also, what about $obj1 + $obj2: Int? Float? Array?
This is where operator over-loading would be useful however perhaps only
explicit casts would make sense here.
Another example: str_replace($obj1, bar, foo); what to call?
__toString or __toArray? str_replace accepts both.
This is an interesting situation, could be resolved by attempting a
__cast('array') followed by a __cast('string') if the first call was
rejected (false, exception or something).
IMHO it would only make sense to invoke methods on explicit casts
only, otherwise it will just be a mess with PHP's current type
juggling. But, as we seen with __toString, limiting the field of
application was annoying (and it was later extended to nearly all
string usages).
I would agree with this as well, only called during explicit casts.
So, what will it be? Inconsistent and Confusing or Limited and Annoying?
One other alternative, probably not as easy would be to pass multiple types
to cast, much the way the Accepts: HTTP header does, providing a list of
possible cast types, in the preferred order.
One could even implement an interface such as:
interface Castable {
function GetCastableTypes();
}
or some such.

I found [PHP-DEV] RFC array functions from 2006, but nothing really

The need to use next, prev in combination is ridiculous compared to a clean
array_hasmore or array_pos_islast, as the internals already know this.
To get an array_valid_position or array_pos_isvalid wouldn't be bad either.
So would it possible to introduce:
array_pos_isfirst( $array)
array_pos_islast( $array)
array_pos_isvalid( $array)

Christian, the best way to enter in the zend engine, it's to create a zend extension project, then go thru all the step of the code to manipulate the hashtable, learn where object are living in the tree, then when you know how to play with the public interface, that's really easy to go deeper, the zend bytecode engine is so far less complex that what you could find in any JVM (I know a couple of things in area) even python bytecode and how the interpreter is able to handle various version, in two weeks you should have done your tour by using the zend interface and reading the code, php zend core is tiny in term of code, the only things that could appear weird and clumsy is the semantic code used, this is the only thing that could appear like a mind barrier.

Hi Christian, The PHP architecture is a little different from the JVM in that it does not explicitly document/specify the interface between the compiler and the bytecode/opcode interpreter the way that Java does. It still exists though. I suggest you look at the links under here: http://www.php.net/manual/en/internals2.php In particular: http://www.php.net/manual/en/internals2.opcodes.php Another good reference is Sara Goleman's book Extending and Embedding PHP Andy Wharmby produced a set of charts which you can find on Zoe's Blog here : http://zoomsplatter.blogspot.com/2008/08/php-opcodes.html . These may help you to make a fast start understanding the overall design.

Well there's one quite complete document about it available - the source code ;-) PHP isn't developed following standards but simply by implementing and extending it.

Do you want to learn how to use it better or academic reasons or something else? - Depending on all that the focus of the learning might be quite different. As a starting point for this I recently created a small toy project: A minimal basic inspired language on top of the ZendVM, just 200 lines of C code which might give a few pointers to do further research. It's quite hackish ugly code but enough to compile and execute a script like this: 10 GOTO 40 20 PRINT B 30 END 40 PRINT A 50 GOTO 20 This all will be compiled to Zend Opcodes which can be executed, cached with APC, dumped by vld, ...

made and the reason why.
I also read why it have been refused here :

In combination with the new input_filter extension
you then reach the original goal of setting a default
value to a non-set input variable with:
$blahblah = input_filter_get(GET, 'foo', FL_INT) ?: 42;

I don't see how do that with the actual filter extension. Even if it is
possible, this is not a pretty short and easier solution than :
$var = (isset($var)) ? $var : 'default';
The ternary isn't meant to solve the isset thing you are talking about.
It is simply a shortcut to normal ternary operations. The most common
case where you don't know if a variable is set is on the initial input
via $_GET or $_POST and we definitely don't want people doing:
$var = $_GET['foo'] ?: 42;
It would be an XSS disaster. Hence the suggestion to use input_filter
there, or a similar user-supplied filtering function in which case the
ternary, as it is currently implemented, is perfectly suitable.

Re: [PHP-DEV] Intervals representation with brackets
Hello, Even if you are introducing a new syntax, your approach is wrong to get intersection and interval, I was not talkative but the samples I gave you expose several cases // This isn't bad, but it's not really what i want, and... what I wrote! ;-) so I guess you don't even understand what your are doing ? playing with range, you may read the documentation about those objects into the Apple Foundation those are following the same model, dealing with list of ranges. anyway what you exposed was really unclear, try to be more didactic, we don't have crystal balls, and somehow Ijust trolled you like you did, so please we are people we need a context.

GLOBALS_ID_BASE 30 when the largest reserved value is 18? Maybe I'm missing something. I reserved IDs for the subsystems I thought were core. I was sure there'd be others that I'd missed and so I left space for more. Would there be significant memory space or locality issues if one ID per extension in the PHP source bundle was reserved upfront, even if those extensions were never enabled?

Hi Jill,

$item is now a reference to the last element of $items.

foreach ($items as $item) { }
And here, the foreach loop writes to $item for each element: thus
assiging that value to the last element of $items.
The last element of $items is 'carrot'. Why does it print apple, banana,
banana?
It sounds like you're saying that $item should be left with the value
'carrot', which makes sense, but why would the original array be modified?
(These are empty foreach loops.)
print_r($items);
?
// Output:
Array
(
[0] = apple
[1] = banana

Array
(
[0] = apple
[1] = banana

Two bananas in the last set?! Not what I expected.
You can fix your bug by using 'unset($item);' after the second
foreach-loop.
