Re: [PHP-DEV] While-else
It can save you one if-statement, where the condition would be identical to
the where condition.
Example:
if ($i = 10)
{
while ($i = 10)
{
$i++;
}
}
else
{
echo $i is more than 10\n;
}
I personally hate overspecifications, and this is one situation where that's
the case. So actually, I would like while-else support. Just my humble 2
futile cents of course.

Ron

So it executes after the last iteration?
No.
It must only execute if there were no iterations?...

I have wanted to use this kind of syntax a couple of times, for example:
?php
while ($line = mysql_fetch_array(...)) {
echo $line;
} else {
echo 'Sorry no records';
}
?
Otherwise I would write the above code as a while + a if.
However I'm unsure if this syntax should be put into PHP, but I thought I'll
just post a example of when I would use it.

Re: [PHP-DEV] Trying to understand PHP6's unicode support
php6 always handles all internal work in utf-8
But, from what I remember, there should be a way to specify encoding
in which you expect data to arrive (in this example from mysql_*)
I think, that someone who knows more will give you more details

I use a mysql database, with iso-8859-1 (Portuguese - latin 1) text, with

What I was trying to understand was, because unicode.runtime_encoding =
iso-8859-1, I tought that all internal operations were done in this
encoding, and only when outputting (unicode.output_encoding = utf-8) data
would be converted to utf-8. So to me, I did a mysql query with latin1, data
comes to my variables as iso-8859-1, I use them, and only when I echo'ed
them, they would become utf-8, from a iso-8859-1-to-utf-8-like function.
But when I do query in any record that have accented characters I get this
warning (using mysql_fetch_assoc):
--
Could not convert binary string to Unicode string (converter UTF-8 failed on
bytes (0xE7) at offset 9)
--
for all accented characters in all fields.
The strange thing to me, is the mysql_fetch_assoc function give this error
even before I accessed the field values, as I understanded from the above
explanation.
If I changed the set names query to:
mysql_query('set names utf8', $this-mysql_link);
then it works, but I would like to understand how this works, to make my
program the right way from the start.
Did I misundertood something?

I've recently start using the daily snapshots op PHP, but I also tried it on
version 5.2.1, which shows the same result. It used to work just fine, so
I'm sure this isn't the expected result. I've recently upgraded from Ubuntu
Edgy (6.10) to Feisty (7.04), with kernel and apache update, so I believe
that the problem is related to that.
I've straced the process (see attachment), but I can't pinpoint the problem.
This is a big issue for me, can anyone point me in the right direction to
find the source of this problem.
Thanks,
Arnold
snip
Well, I've also tested this code, and it does work fine. BUT if
/tmp/pear doesn't exists, what i had at first, then file_exists
returns false, because file_exists follows symlinks, and the symlink
pointed to nothing. So if you're sure that $symlink is a link, then it
might be better to check it with is_link.
Also, the is_link function is cached, so you might want to add one or
more clearstatcache() in your script.
I checked your strace also, but it doesn't look like there's a bug.
But I've never studied on the PHP core so
Well, if above doesn't help you, then one of the real experts needs
to look at it :)

I think you are confusing PHP features with MySQL features. By running
'SET NAMES' query you set client, connection and result character sets in
MySQL (see http://dev.mysql.com/doc/refman/4.1/en/charset.html). It is not
related to PHP. MySQL has internal character set support since 4.1
version.

Re: [PHP-DEV] [patch] Dynamic access of static members/methods, and constants
Hi,
In this way, classes can be considered as polymorphism, just like objects.
So is it OK to allow abstract static function in abstract class to support
this feature directory? Currently it is forbidden in HEAD, only interfaces
can have static function.
Thanks
2007/4/27, Etienne Kneuss [EMAIL PROTECTED]:
Hi,
I've already proposed that 1-2 months ago, but now seems to be a good
time to discuss new things, so let's try again:
I believe it would be nice to be able to dynamically reference static
members, constants, and methods.
Currently, there is no way to do that and the only way would be to
create a static method and use call_user_func(array($classname,
'getThat'));
In other words:
class A {
public static $foo = 'value1';
const gee = 'value2';
public static function bar() { return 'value3'; }
// old way:
public static function getFoo() { return self::$foo; }
public static function getGee() { return self::gee; }
}
$classname = 'A';
echo $classname::$foo; // value1
echo $classname::gee; // value2
echo $classname::bar(); // value3
// --- instead of: ---
$classname = 'A';
echo call_user_func(array($classname, 'getFoo')); // value1
echo call_user_func(array($classname, 'getGee')); // value2
echo call_user_func(array($classname, 'bar'));// value3
which is quite slow.
Please take a look at the patch[1] I made for it. Comments would be
appreciated!

Python Perl already have this function. So why not PHP?
The 'but everyone else is doing it' argument is particularly weak when
it's not actually accurate.
$ man perlsyn
The following compound statements may be used to control flow:
[...]
LABEL while (EXPR) BLOCK
LABEL while (EXPR) BLOCK continue BLOCK
$ perl -le '$i = 99; while ($i 10) { $i++; } else { print Oh...; }'

I can't see any point in it myself. It doesn't read naturally and it
doesn't add anything that you don't get by preceding your
while with a simple if statement.

I have wanted to use this kind of syntax a couple of times, for
example:
?php
while ($line = mysql_fetch_array(...)) {
echo $line;
} else {
echo 'Sorry no records';
}
?
Otherwise I would write the above code as a while + a if.
However I'm unsure if this syntax should be put into PHP, but I
thought I'll
just post a example of when I would use it.
I can understand how it works now, and where you'd use it...
And I still don't care for it...
I mean, 'else' just doesn't go with 'while', to me...
And you rarely need something as convoluted as the other example.
while ($line = mysql_fetch_array(...)){
echo $line; //not really right, btw... :-)
}
if (!mysql_num_rows(...)){
echo no records;
}
So, really, it just makes confusing PHP code, that doesn't seem to
save much, in most real-world cases I can think of.

Re: [PHP-DEV] [patch] Dynamic access of static members/methods, and constants
Hi,
Stanislav Malyshev wrote:
Could you describe a couple of use cases where you would use such
things (i.e. in real world scripts/libraries)?
Sure, let's take an example:
You have a library that uses a factory pattern, but you'd like to cache
those already generated objects in a static variable in the class. Now,
this feature is required in many classes and you'd not like to duplicate
too much code, so a solution would be:
class MySuperClass {
private static $_objectsLoaded = array();
public static function factory($pkId, $classname = __CLASS__) {
if(isset($_objectsLoaded[$classname][$pkId])) {
return $_objectsLoaded[$classname][$pkId];
}
$o = new $classname();
//load stuff from the database
$table = $classname::$_table;
$pkField = $classname::$_pkField;
// build query using $table, and $pkField, load stuff into $o, etc..
if(!is_array(self::$_objectsLoaded[$classname])) {
self::$_objectsLoaded[$classname] = array();
}
self::$_objectsLoaded[$classname][$pkId] = $o;
return $o;
}
public static function create($classname = __CLASS__) {
$o = new $classname();
// ...
return $o;
}
}
class MyClass extends MySuperClass {
protected static $_pkField = 'id';
protected static $_table = 'theTable';
public static factory($pkId, $classname = __CLASS__) {
return parent::factory($pkId,$classname);
}
public static create($classname = __CLASS__) {
return parent::create($classname);
}
// ...
}
There may be some typos in the code above that makes its syntax
incorrect, but the idea is here.
Now, as you can see, because late static binding is not yet implemented
and probably never will be because of the overhead it might introduce,
you've to pass the classname as a parameter and use it to request things
from the child's class, at this point, being able to do that using that
$classname:: shortcut is quite elegant, instead of having to use
overkill call_user_func calls as all those _get*() methods would have to
be redefined in every the child classes.
I wouldn't mind having to use multiple call_user_func calls for that
purpose if I knew it was too hard to implement that $classname:: thing,
but it's so easy that I really believe it's a feature worth having. And
PHP is also about multiple ways of doing something, right ? :)

Your suggestion is promising, but it might be a bit too wide for people that have smaller screen resolutions. I think we need to make it look good at 1024x768. Yes, the page is too wide. The reason for this is that this is actually not a website but a rearranged screenshot. I noticed too late that the page has a bad width. There are some things you have missed. There are two different source bundles (gz and bz2). Next build depends on the system (source or bins) and the PHP version (we build some windows snapshots more often than others). Maybe I missed the things because I was led from the dream that the different build intervals could be simplified too. ;) But you are right these are things I didn't pay attention to. I could make a new suggestion tomorrow and try to integrate the missing things. Thanks for the heads up. This should be fixed now. This was a very fast fix and indeed I can now download the installer. Would you be willing to produce the HTML needed for the redesign? Unfortunately my knowledge about HTML and CSS is very limited, so I don't think the page would look very good in case I did it.
