[PHP-DEV] php-dev summaries (Re: [PHP-DEV] suggestions for ze2)
Actually, I think it's a good idea to make a summary of all those discussions What about an always available discussion documentation on php.net ?

Re: [PHP-DEV] when PHP code causes crash due to bad input, is it a bug?
Thanks for sticking with the issue, Greg. If I may make an objective observation... Random users constantly submit issues to the bug database that are clearly not problems with PHP, issues that are better addressed in the mailing lists. I imagine it must be frustrating to the QA team to have people constantly blaming PHP for bugs in their scripts. Sometimes issues are mistakenly changed to bogus when they shouldn't be. And as a bug submitter it's easy to think bogus really means you're a liar or an idiot. It doesn't. It just seems to be a space we've reached where resolution of bug reports isn't perfect. The best idea I have is to remain polite and persistent. Hey, at least no one used a swear word. Since you have lots of experience doing QA, you probably already understand this and maybe you have some ideas for how the process can improve.

[PHP-DEV] Is exif_tagname() useful?
The undocumented function exif_tagname() does lookups on the table tag_table_IFD which matches IDF0 tags to human-readable names. Considering exif_read_data() already uses this table, is there a reason to have this function around?

Re: [PHP-DEV] Designing for PHP4 with PHP5 in mind...
Any good links you could throw my way describing proposed changes?
There are archives of the Zend Engine 2 list at zend.com:
http://www.zend.com/lists.php
There is one big change with objects that will break BC. Objects pass by
reference instead of value, both for function calls and assignments. For
example:
?
class a {}
function c($c)
{
$c-name = 'C';
}
$a = new a;
$b = $a;
$a-name = A;
print($a-name);
$b-name = B;
print($a-name);
c($a);
print($a-name);
?
In ZE1 you get AAA. In ZE2 you get ABC.

When he asked, what gives? his uncle told him, if you're not fighting, you're not dancing. (It may help to imagine this said with a yiddish accent).

If you really need this behavior, do something like
assert('func_num_args() == 1');
That should generate the warning you describe if assertions are turned on.

Re: [PHP-DEV] RC4: ground rules
Possible values are: - php_auth_exposure=user Only PHP_AUTH_USER is exposed. - php_auth_exposure=pw Only PHP_AUTH_PW is exposed - php_auth_exposure=user,pw Both PHP_AUTH_USER and PHP_AUTH_PW are exposeed Moriyoshi, have you considered using constants here instead of strings? For example: - php_auth_exposure=AUTH_EXPOSE_USER Only PHP_AUTH_USER is exposed. - php_auth_exposure=AUTH_EXPOSE_PW Only PHP_AUTH_PW is exposed - php_auth_exposure=AUTH_EXPOSE_USER | AUTH_EXPOSE_PW Both PHP_AUTH_USER and PHP_AUTH_PW are exposeed It resembles the style used by error reporting, which will be less confusing for novices.

Re: [PHP-DEV] RC4: ground rules
There is no difference here, both are strings anyway. And the latest option AUTH_EXPOSE_USER | AUTH_EXPOSE_PW wont work in an httpd.conf file. Also, this is NOT the style we have in php.ini. I don't see any valid point to use this thing. Derick, you may have a point about it not being as friendly to httpd.conf, but if you look at php.ini-dist, you'll see: ; If you use constants in your value, and these constants belong to a ; dynamically loaded extension (either a PHP extension or a Zend extension), ; you may only use these constants *after* the line that loads the extension. Which implies constants ARE available inside php.ini. (Yes, I know they aren't in httpd.conf or .htaccess). You'll also see this: ; error_reporting is a bit-field. Or each number up to get desired error ; reporting level [snip] ; Examples: ; ; - Show all errors, except for notices ; ;error_reporting = E_ALL ~E_NOTICE Which is the style I was talking about. The patch in question is using two flags, which suggests the a bitfield. It's true there's at least one ini setting that uses a string of comma-separated values (mbstring's encoding settings), but are there other examples of setting a couple of on/off values in a string like this? I guess variables_order is kind of like this. Maybe it would be better to have two flag directives instead of one value directive. Anyway, it probably doesn't matter.

Re: [PHP-DEV] CGI and CLI (compromise proposal)
After having consulted with Andrei, Derick and others on irc here is a proposal for a compromise: On Unix: 1. Both cgi and cli are built as 'php' in their respective sapi directories (pretty much as it is today except that cgi gets renamed back from php-cgi to just php). 2. Make install will *not* install cli if cgi build was selected (only cgi gets installed). 3. A new install target 'install-cli' is introduced so that make install-cli will overwrite whatever is in $(PREFIX)/bin/php. On Windows: 1. php.exe in the root of distribution is php cgi sapi. 2. New cli directory is included with php.exe (cli) in it. If this is an acceptable compromise I volunteer to do the changes required. This goes to show that good ideas usually win out and our system works. I proposed cli/php.exe on Windows back on December 9th, but there was a fear it would be a support nightmare. I take it those fears have subsided. I'm also glad that limb I went out on didn't break afterall. I'd say that I fully support this proposal but I'm not sure my opinion matters. ;) Leon -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DEV] php.exe - php-cgi.exe
out on a limb Would it be a tragedy to name both the CLI and CGI versions php on UNIX and php.exe on Windows? On UNIX, it doesn't seem like there'd be much confusion because make install would put sapi/cli/php in /usr/local/bin and sapi/cgi/php in /usr/local/apache/cgi-bin. For the Windows distro, php.exe in the root of the archive could be the CGI (as usual) and sapi/php.exe could be the CLI version. It might be better to have sapi/cli/php.exe (along with parallel changes for the DLLs in that directory). /out on a limb Leon -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DEV] php.exe - php-cgi.exe
As Leon has suggested, why not just compile the variants into different directories? Say add a cli/ (since the CLI is newer). Only one directory would go into the PATH (presumably). That would also affect the ini setting for extension_dir. The default value is ./ indicating the same directory as the executable. I would prefer everthing to be in the same directory. This way I dont have to mess with php.ini when I have multiple installations on the same system. Yes, that's true. On the other hand, there's something strange about php.ini's extension_dir and the extensions directory. I found it a lot easier and cleaner to wipe out that line from php.ini than move all the extension up a directory. (If you don't set extension_dir, it uses c:\php4\extensions.) Wow, I guess I may have really stepped in it because I was just about to suggest the php.ini default setting change. ;) Leon -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] Making NULL a scalar
It seems like the NULL type is a scalar type, ie it has a discrete set of
values. I suppose from an SQL perspective, one could argue NULL is a
special value that destroys any attempts at evaluation. However, PHP has a
precedent that relates to this issue: the ctype functions. For example,
is_alpha('') is TRUE...of course, because the null set is always a part of
every set (in textbook mathematics, anyway).
Anyway, the is_scalar() function is currently returning FALSE when passed a
NULL value. May I suggest adding the IS_NULL constant to the top part of
this function's case statement? I'm not sure if this has negative BC
issues.
I don't feel particularly passionate about this issue, it just occurred to
me as I was reviewing the function.
Comments?
Thanks,
Leon

[PHP-DEV] is_callable Bug 20216
Can someone shed some light on is_callable? I think I understand it's meant
for testing whether a function or method is callable, but it would be nice
to get some confirmation from someone who knows for sure. Philip and I are
trying to add this function to the manual.
Here are some rough notes I have on my understanding of the function (from
http://bugs.php.net/bug.php?id=20216):
This function wraps zend_is_callable. The first argument is the name
of a function or method. Class and object methods are specified by
passing an array with two elements: class or object and method name.
The second argument seems to be for checking syntax only, but I can't
figure out how to make is_callable return FALSE when the second
argument is TRUE.
The third argument receives the callable name. In the example below
it's a::b. Note, however, that despite the implication that a::b()
is a callable static method, this is not the case.
?
class a
{
var $c;
function b()
{
return($this-c);
}
}
$d = new a;
if(is_callable(array($d, 'b'), FALSE, $name))
{
print($name);
}
?
Thanks!

Re: [PHP-DEV] is_callable Bug 20216
The second argument seems to be for checking syntax only, but I can't
figure out how to make is_callable return FALSE when the second
argument is TRUE.
Try this:
var_dump(is_callable(array(1,2), true));
Hmm...OK. Yes, that does make is_callable return false. Can you explain
the logic behind this? I tried lots of other values and got TRUE. For
example:
var_dump(is_callable(array('$$$','%^'), true));
var_dump(is_callable('%^', true));
These aren't valid identifiers, but the function is (apparently) reporting
that syntax is OK.
Well, $name is just supposed to indicate which class/method you were
checking. It doesn't tell you whether the method is static or not,
because in PHP 4 it doesn't make sense.
Ah, yeah, I guess there isn't a way to tell if a method is callable
statically or not unless you check that it contains no references to
instance properties.
So, would it be fair to say this function is intended for debugging the
core? And, if you have the time, could you describe the situation where
this function is useful?
Thanks Much!

Re: [PHP-DEV] PHP and Threading
I was wondering, is PHP in future going to support threading? This would be a very nice feature. I'am currently working on this project of mine, a FTP Server build in PHP which serve MySQL database records. It actually does work very nice, also multiple clients at the same time. It supports passive and active FTP. But my problem here is that the FTP server only can handle one file transfer at a time. Threading would be the solution. Are there any plans implementing it? Take a look at the process control functions. (I only recently noticed them myself). http://www.php.net/manual/en/ref.pcntl.php It sounds like you need to fork on an accepted connection.

$this-salutation = 'Hello';

//use the abstract class correctly

//use it incorrectly, get an exception

Hi,
does PHP4 with the ZE2 supports abstract function like Delphi or C++?
That would be very useful for class development, cause we can avoid
testing if a class is abstract if an abstract class couldn't be
instantiated?
Syntax could be like in C++
class X
{
X(){}
int y() = 0;
}
or little bit more like pascal
class X
{
X(){} // PHP
function x(); abstract;
}
or
class X
{
X(){} // PHP
abstract function x();
}
Greetings,
Jens
