Re: [PHP-DEV] Moving extensions to PECL
If I may, I'd like to suggest that if you want to emphasize PEAR in PHP5,
that someone should look at bug 20933, to either verify that it is a bug,
or make it clear that this new behavior is intended. (The bug is about
isset() on a string subset like $a{1} always returning false.)
Only because at the moment, pear/Console/Getopt.php depends on the old
behavior, and so the 'pear' package manager script is broken. There's some
reluctance to accept a workaround patch to acommodate ZE2 when the problem
might just go away eventually.

Re: [PHP-DEV] $scalar{index} syntax
yes, whoosp, just found that page. the problem turns out to be
that isset($string{n}) is always false with ZE2, and empty($string{n}) is
always true. same for $string[n]. it works with ZE1, so i'll
just log the bug.
(though it does kick out an 'Uninitialized...' notice, which the same
test on an array key or object property does not. i sympathize with the
bugs that have been logged about that, which have generally been marked
Bogus. but that can be suppressed with @, at least, so not a big thing.)

You mean $string{2} ? That's the more correct way to do $string[2] to
make it clear that it is a character offset. This has been supported for
years and will not go away.

[PHP-DEV] overridden php.ini directives in CLI version
shouldn't 'output_buffering' be overridden to 0 (off) in the CLI SAPI? doesn't help to override 'implicit_flush' but not that one. especially since there's no way to turn off the ini-level output buffering from a script. you can't end it with ob_end_*() and you can't set it with ini_set(). whereas anyone who wants output buffering in a script can always turn it on themselves. i know it defaults to off in php.ini-dist, but don't underestimate the appeal of the word 'recommended'... -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] cvsclean removes pear/PEAR on OS X 10.2
I think this is the darned case-insensitivity causing a problem again. the pear/.cvsignore file lists 'pear' - meaning the installer, presumably - but when cvsclean does a remove of it, it ends up removing the PEAR directory. (this came up because the 10.2 upgrade installed a too-new version of autoconf, so buildconf is running cvsclean) i honestly can't see what to do about it except to build the 'pear' file inside a directory, so that it's not parallel to the PEAR directory... -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] ZEND_PUTC question
I was looking at compile warnings for 4.3, and came across this in Zend/zend.h /* output support */ #define ZEND_WRITE(str, str_len)zend_write((str), (str_len)) #define ZEND_PUTS(str) zend_write((str), strlen((str))) #define ZEND_PUTC(c)zend_write((c), 1), (c) is there a reason why that last line isn't just #define ZEND_PUTC(c)zend_write((c), 1) ?? -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DEV] on the subject of overloading: __call()

BB related topic: in the current state of ze2, there are several ways to

Since __call is the method of the class, calling self::method can be
achieved, I think. As for the second point - could you please explain
furher what you mean, maybe with an example?
right, because static method calls don't get caught by __call, so you
always have $this.
the basic problem is that as it is now, if i do any of these
self::a_method($arg1,$arg2);
parent::a_method($arg1,$arg2);
some_other_class::a_method($arg1,$arg2);
inside of a class's method, $this is visible inside those called methods,
and points to the calling object.
but there is no way to make equivalent calls using call_user_func()
or call_user_func_array(). you can't use parent::a_method,
array($this,'parent::a_method'), array(parent,a_method),
or array('parent',a_method). if you use the literal class name,
call_user_func_array(array(get_parent_class($this),'a_method'), $args);
it doesn't fail, but it's as if you were making a static method call
from outside of an object context - $this is not defined.
it's the last two cases - parent:: and some_other_class:: - that relate
to __call(), as you point out. and what truly matters is call_user_func_array(),
because not having it means you can't hand off the arguments from __call()'s
parameters to a method in the parent class or in some other class. not without
writing some pretty hacky eval() code, that is.
(btw, there should probably be a warning in the docs that methods that
are expecting to force their parameters to be references will not work
as expected when called by call_user_func_array().)
i'm attaching kind of long test case code resulting output that
show what i mean.

was there discussion about the interaction of __call() and methods which declaring their arguments as references? there's no way at present to make this work, as far as i can tell. seems like it could just be a documented limitation, but i thought i'd check. related topic: in the current state of ze2, there are several ways to call methods directly that can't be emulated by call_user_func() - calling self::method() for instance, or the visibility of $this if you call class::method(). is that likely to stay true? -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

It works when you turn on always_populate_raw_post_data, right?
kind of. it doesn't quite follow the doc blurb - even if always_populate
is turned on, if the content type IS recognized, and it's not the default
- which right now means only multipart/form-data far as i can tell -
then HTTP_RAW_POST_DATA is not set. something should be changed to
take that into account, either making it work with multipart/form-data
or changing the documentation.
also, there was a small change i had to make in php_content_types.c to
make it pick up XML data without getting an error about the string

[PHP-DEV] overload() crashes in ZE2
trying to build CVS version with ZendEngine2 and use the overload extension.
PHP crashes with a bus error on the call to overload(). it's a hash table
problem, over my head for sure. i can't get this to work at all and wonder
if it's a Darwin(OS X) issue. has anyone else run into this?
this is the compile process:
cvs checkout php4
cd php4
cvs checkout ZendEngine2
then i have to edit ZendEngine2/Zend.m4 to change this line:
fprintf(fp, %d %d\n, ZEND_MM_ALIGNMENT, zeros);
to add that '\n' char, or else configure fails and ZEND_MM_ALIGNMENT
and ZEND_MM_ALIGNMENT_LOG2 don't get defined correctly - you can see
why i'm thinking this is a platform and/or config problem...
then continuing:
./buildconf --ZendEngine2
mv Zend Zend1.2
mv ZendEngine2 Zend
./configure
