Have you tried this:
function format_string($string) {
// format the string...
$result = string;
if (isset($this)) $this-elements[] = $result;
return $result;
}
In this form you can check the existance of $this. If you call the
method statically then $this is not present and the elements array is
not filled. If you call it non-statically then $this is present and
elements is filled. The same you can do with show_all().

[PHP] Overwriting offset methods of ArrayObject
Hello,
I just tried to overwrite a method of ArrayObject like this:
class MyArrayObject extends ArrayObject
{
public function offsetGet($key)
{
echo Here I am\n;
return parent::offsetGet($key);
}
}
$o = new MyArrayObject();
$o['test'] = 'test';
echo $o['test'];
I think this should output the text Here I am because I have
overwritten the offsetGet method of ArrayObject which is called if I
access an array element of this object. But it doesn't. My method is
simply ignored.
Then I've written a simple Object which implements the ArrayAccess
interface like the ArrayObject object does. And then I have done the
same as above but this time I don't extend ArrayObject but my own
object. This works. My overwrite method is called
I'm confused. Why can't I overwrite the method in ArrayObject? Is this a
bug? Or are the methods of ArrayObject marked as final? But even then
I must get an Cannot override final method error.
Some hints if I misunderstood something? If not I'm going to file a bug
report.

Yes, that's a possibility. You can even create more stuff in this
Projects class like createProject, removeProject and stuff like this. If
these tasks are pretty static and you don't need multiple instances of
the Projects class then you can implement it completely statically so
you don't need to instanciate the class:
class Projects
{
private static $projects = array();
public static function getAll()
{
return self::$projects;
}
public static function add(Project $project)
{
self::$projects[] = $project;
}
}
So now you can do this to get the projects:
$projects = Projects::getAll();
Adding objects to the list can be done by the constructor of the Project
class:
function __construct()
{
Projects::add($this);

[PHP] Shorthand functions (was: Code Snippets' you couldn't live without)
Murray @ PlanetThoughtful wrote: with exploring include files to find out what a function does or how a class operates. I doubt half-a-dozen shorthand functions in that include file would place a measurable strain on the readability or maintainability of a project. I disagree on that. The problem here is not that the functions are short. The problem is, that their names gives absolutely no clue about what they are doing. mfr() can be mysql_free_result() but it also can be mysql_fetch_row(). So it's not only unreadable, it's also error-prone. Sure, it's possible to look up what this function is doing. But is it necessary? Everybody (even coders not knowing the mysql functions) can understand what mysql_free_result() is doing, without decyphering it first. But I agree that many PHP functions are named too long. But this is because they are non-OO functions living without namespaces. So if you don't use OO (where you may write something short like $res-free() you have to live with that, I fear. Or write shorthand functions, nobody can keep you from doing so. I just said, that it is problematic for more professional projects where new programmers may begin to work on at any time). And I agree that there are even some very short function names in PHP like nl2br(). This looks like a bad naming, but it is not really. nl is a well known shorthand for newline. 2 makes clear that it converts something. And br is named after the HTML-Tag. So this function name GIVES some clues about what it is doing. But for newcomers it may not be clear at the beginning what this function is doing. But after a quick lookup the newcomer can remember the meaning very well. And I think this is different with functions like mfr() and asl() which gives no clue about their meaning. when first viewed by someone new to PHP. Also witness the deprecation of variables such as $HTTP_GET_VARS in favour of $_GET etc. $_GET and $_POST are well named. It's clear what they are doing. Thank god their were not named $_HGV and $_HPV. Or the .= concatenation assignment operator as a shorthand to $var = $var . ' added string.' $a .= $b is not a shorthand of $a = $a . $b. The result is the same but the internal processing is totally different. $a .= $b is a lot faster then $a = $a . $b because $b is directly appended to $a. The second form constructs a completely new string and overwrites the old value of $a. At least this is the case if no optimizer is used. Maybe optimizeres are transforming the second form into the first form, don't know. So you can't compare this to a shorthand function. It was not introduced because coders are to lazy to write the long form. It was introduced because it is absolutely intuitive to do so if the language already has something like +=. But I can't tell if these operators were introduced into the C programming language (or wherever it appeared first) because lazy coders. ;-) Back to the intent rather than the form of my original question: what are the code snippets you can't live without?

Very true. In Java (with Tomcat for example) you have a real session scope and application scope where you can put objects and directly access them. These objects are hold in memory and they are REAL objects between the requests. In PHP it's different. If a HTTP request is finished then the session (with all data including objects) is serialized and stored on the harddisk (or database or whatever the session backend is). On the next HTTP request the session is loaded from harddisk and unserialized. So new objects are created and filled with data from the harddisk at every request.

No. I must admit, It don't understand it. Let me try: You have a script
a.php which outputs this static content:
img src=b.php
b.php outputs the static content img src=c.jpeg
This can't work. You browser tries to download an image with the name
'img src=c.jpeg'. I think THAT's your problem and the reason why I
did not understand you problem. If you use a PHP script inside an img
src attribute then this PHP-Script must output an image. Complete with
content-type header and the image as binary data in the body.
Or another solution for a.php:
html
body
img src=?php include('b.php')? /
/body
/html
but I don't see the sense here. You can just do all this in one script:
?php
$curr_time = (localtime());
if ($curr_time[2] = 6 and $curr_time[2] = 17) {
$img = 'a.jpg';
}
else {
$img = 'b.jpg';
}

html

img src=?=$img? /

/html

And two more functions I'm using regularly: mkpath($path, $mode) - Create a directory with all parent directories and make sure the directory mode is really set (setting umask to 0 during directory creation) redirect($url) - Creates a correct url (absolute and with SID if needed), sends location header and exits the script. -- Bye, K http://www.ailis.de/~k/ (FidoNet: 2:240/2188.18) [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) signature.asc Description: OpenPGP digital signature

So your looking from something that starts with '{' and continues

If you are already using the ? meta character then you can simply do this:
/{(.*?)}/
The while not-approch is useful if you don't want to use the ? meta
character (to be compatible to regex engines which don't support this).
But then it would look like this:
/{([^}]*)}/
But all these expressions are to lazy for the required work. The tags
should be matched more exactly using this:
/{$([\w\.]+)}/
This implies that the variable names always begin with a dollar
character and they can contain upper and lowercase characters, numbers,
underscores and periods. The variable name must contain at least one
character, so {$} is not matched.

[PHP] localeconv
Hi,
I just noticed an annoying issue with locales in PHP and I'm not sure if
this behaviour is intended or it's a bug.
I'm doing the following:
setlocale(LC_ALL, 'de_DE');
$l = localeconv();
printf(Decimal point: %s\n, $l['decimal_point']);
printf(Thousands sep: %s\n, $l['thousands_sep']);
This should output a , as decimal point and a . as thousands
separator but it does only output the standard characters (A dot as
decimal point and nothing as thousands_sep).
My de_DE locale is properly set up. All other data returned by
localeconv is correct (EUR currency, Euro currency symbol, monetary
decimal point and monetary thousand separator and so on). Only the
decimal_point and thousands_sep is not working.
Also interesting is that printf(%.2f, 123.45) correctly outputs
123,45. So PHP IS using a comma as decimal point but why does it not
show up in localeconv()?
I tried exactly the same code in C on the same machine and this is
working perfectly:
#include locale.h
int main(int argc, char *argv[])
{
struct lconv *l;
setlocale(LC_ALL, de_DE);
l = localeconv();
printf(Decimal point: %s\n, l-decimal_point);
printf(Thousands sep: %s\n, l-thousands_sep);
return 0;
}
This outputs correct german decimal point and thousands separator.
Is there a reason for this misbehaviour of PHP? Or is it a bug? I
encounter this with PHP 5.0.2 and 4.3.9.

Runing this we get: true bool(false) int(0)
Are you sure you posted the example correctly? It outputs this: false
bool(false) int(0)
And this output is absolutely correct. Your condition gives new values
to $a and $b because you use = and not ==. So you do this:
$b = 0;
$a = 1 $b;
The condition checks the value of $a (which is false) and so you land in
the else branch and that's why $b is int(0) and $a is bool(false)
I think you want this:
if ($a == 1 $b == 0)

Your condition gives new values to $a and $b because you use = and not ==. So you do this: Maybe you never read this: http://hu2.php.net/manual/en/language.operators.php#language.operators.precedence The result is not so obvious. There sould some internal behavior which cause this. I don't see the problem. The behaviour of your code matches the precendences in my opinion: $a = 1 $b = 0 PHP sees two expressions here: $a = 1 $b (because has higher priority than =) and $b = 0; So the condition resolves to 1 0 while $a is set to false and $b is set to 0; So where is the problem? -- Bye, K http://www.ailis.de/~k/ (FidoNet: 2:240/2188.18) [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) signature.asc Description: OpenPGP digital signature

Hodicska Gergely wrote: $a = 1 $b = 0 PHP sees two expressions here: After the precedence table the first thing should be evaluating 1 $b, so we get: $a = false = 0 Which is not meaningful thing, and maybe this cause that the evaluating of the statment is not in the right order. = has a right associativity. This is well explained on the page you think I have not read. See Example 15-1. $b = 0 is evaluated first and the 1 $b is evaluated after that. Everything else would make no sense. (1 $b) = 0 is not a valid expression and throws an error. -- Bye, K http://www.ailis.de/~k/ (FidoNet: 2:240/2188.18) [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) signature.asc Description: OpenPGP digital signature
Re: [PHP] php compiler
Hodicska Gergely wrote: Oke, but has a higher precedence. The right associativity has sense when all the operand has the same precedence. I think the precedence of left and right associative operands can't be compared. The switch between associativities already separates the expression (if it could be explained this way). So you have to handle left-evaluated expressions and right-evaluated expressions separately. That's why $b = 0 and 1 $b are evaluated separately. The PHP manual gives a fine example: Note: Although ! has a higher precedence than =, PHP will still allow expressions similar to the following: if (!$a = foo()), in which case the output from foo() is put into $a. And that's because = is right and ! is non-associative. -- Bye, K http://www.ailis.de/~k/ (FidoNet: 2:240/2188.18) [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) signature.asc Description: OpenPGP digital signature
[PHP] imagecopyresampled()
Hello, I have a problem with imagecopyresampled() and I'm not sure if this is a bug in GD or PHP or it's a feature. I'm trying to do the following (This example doesn't make much sense, it's just a simple way to reproduce the problem): I have an alphatransparent image 512x512. I want to resample that image to 256x256 and draw it onto a blue background. After that I want the background color to be pixel-transparent. With GD I'm doing it like that: 1. Create new true color image with a size of 255x255 2. Allocate a background color and fill the new image 3. Load the alphatransparent PNG 4. Render the PNG on the background image with imagecopyresampled 5. Define the background color as transparent (imagecolortransparent) 6. Save the image as PNG. Now here is the result: http://www.ailis.de/~k/test/imagecopyresampled/255.png If I do exactly the same with a target image size which is a base of 2 (2, 4, 8, 16, 256) it works. See here: http://www.ailis.de/~k/test/imagecopyresampled/256.png With imagecopyresized everything works fine. But imagecopyresampled has problems with binary uneven target sizes. Is this a GD bug? I'm using PHP 4.3.3 with GD 2.0.23 (The stuff from current Debian Sarge). Does anybody know a solution or a workaround? -- Bye, K http://www.ailis.de/~k/ (FidoNet: 2:240/2188.18) [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
